Subject: [PATCH 001/148] drm/sun4i: Use DRM_GEM_CMA_VMAP_DRIVER_OPS for GEM
operations
Our driver makes a typical use of CMA, with GEM object allocated as
GEM CMA objects. Use DRM_GEM_CMA_VMAP_DRIVER_OPS to describe the ops
instead of duplicating them.
Because DRM_GEM_CMA_VMAP_DRIVER_OPS implements a gem_create_object op
which sets per-object funcs (drm_cma_gem_default_funcs), we can also
get rid of free_object_unlocked and gem_vm_ops, which are superseded
by the object funcs.

Subject: [PATCH 003/148] drm/v3d: Refactor job management.
The CL submission had two jobs embedded in an exec struct. When I
added TFU support, I had to replicate some of the exec stuff and some
of the job stuff. As I went to add CSD, it became clear that actually
what was in exec should just be in the two CL jobs, and it would let
us share a lot more code between the 4 queues.
v2: Fix missing error path in TFU ioctl's bo[] allocation.

From: Eric Anholt <eric@anholt.net>
Date: Tue, 16 Apr 2019 15:58:54 -0700
Subject: [PATCH 004/148] drm/v3d: Add support for compute shader dispatch.
The compute shader dispatch interface is pretty simple -- just pass in
the regs that userspace has passed us, with no CLs to run. However,
with no CL to run it means that we need to do manual cache flushing of
the L2 after the HW execution completes (for SSBO, atomic, and
image_load_store writes that are the output of compute shaders).
This doesn't yet expose the L2 cache's ability to have a region of the
address space not write back to memory (which could be used for
shared_var storage).
So far, the Mesa side has been tested on V3D v4.2 simpenrose (passing
the ES31 tests), and on the kernel side on 7278 (failing atomic
compswap tests in a way that doesn't reproduce on simpenrose).
v2: Fix excessive allocation for the clean_job (reported by Dan
Carpenter). Keep refs on jobs until clean_job is finished, to
avoid spurious MMU errors if the output BOs are freed by userspace
before L2 cleaning is finished.

Subject: [PATCH 006/148] drm/v3d: Add missing implicit synchronization.
It is the expectation of existing userspace (X11 + Mesa, in
particular) that jobs submitted to the kernel against a shared BO will
get implicitly synchronized by their submission order. If we want to
allow clever userspace to disable implicit synchronization, we should
do that under its own submit flag (as amdgpu and lima do).
Note that we currently only implicitly sync for the rendering pass,
not binning -- if you texture-from-pixmap in the binning vertex shader
(vertex coordinate generation), you'll miss out on synchronization.
Fixes flickering when multiple clients are running in parallel,
particularly GL apps and compositors.
v2: Fix a missing refcount on the CSD done fence for L2 cleaning.

+Samsung s6e63m0 AMOLED LCD panel
+
+Required properties:
+ - compatible: "samsung,s6e63m0"
+ - reset-gpios: GPIO spec for reset pin
+ - vdd3-supply: VDD regulator
+ - vci-supply: VCI regulator
+
+The panel must obey rules for SPI slave device specified in document [1].
+
+The device node can contain one 'port' child node with one child
+'endpoint' node, according to the bindings defined in [2]. This
+node should describe panel's video bus.
+
+[1]: Documentation/devicetree/bindings/spi/spi-bus.txt
+[2]: Documentation/devicetree/bindings/media/video-interfaces.txt

+Example:
+
+ s6e63m0: display@0 {
+ compatible = "samsung,s6e63m0";
+ reg = <0>;
+ reset-gpio = <&mp05 5 1>;
+ vdd3-supply = <&ldo12_reg>;

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This patch adds Samsung S6E63M0 AMOLED LCD panel driver, connected over
spi. It's based on already removed, non-device-tree S6E63M0 driver and
panel-samsung-ld9040. It can be found for example in some of Samsung
Aries based phones.

Subject: [PATCH 019/148] drm/panel: Add OSD101T2587-53TS driver
The panel is similar to OSD101T2045-53TS (which is handled by panel-simple)
with one big difference: osd101t2587-53ts needs MIPI_DSI_TURN_ON_PERIPHERAL
message to be sent from the host to be operational and thus can not be
handled by panel-simple.

Subject: [PATCH 031/148] drm/atomic: Create __drm_atomic_helper_crtc_reset()
for subclassing crtc_state.
We already have __drm_atomic_helper_connector_reset() and
__drm_atomic_helper_plane_reset(), extend this to crtc as well.
This will allow us to set default values in the crtc_state, without
having to do it in each driver separately.
Of all drivers that need conversion, only nouveau is done in this
commit, because it wrote its own __drm_atomic_helper_crtc_reset(),
clashing with the drm core.

i915 has its own hw readout and doesn't use the reset helpers directly.
Still it has 2 places where it initialises the crtc_state. Fix those
by calling __drm_atomic_helper_crtc_reset().

Subject: [PATCH 048/148] drm/msm: Convert to using
__drm_atomic_helper_crtc_reset() for reset.
Convert msm to using __drm_atomic_helper_crtc_reset(), instead of
writing its own version. Instead of open coding
destroy_state(), call it directly for freeing the old state.

Subsystem-wide refactorings
===========================
-De-midlayer drivers
--------------------
-
-With the recent ``drm_bus`` cleanup patches for 3.17 it is no longer required
-to have a ``drm_bus`` structure set up. Drivers can directly set up the
-``drm_device`` structure instead of relying on bus methods in ``drm_usb.c``
-and ``drm_pci.c``. The goal is to get rid of the driver's ``->load`` /
-``->unload`` callbacks and open-code the load/unload sequence properly, using
-the new two-stage ``drm_device`` setup/teardown.
-
-Once all existing drivers are converted we can also remove those bus support
-files for USB and platform devices.
-
-All you need is a GPU for a non-converted driver (currently almost all of
-them, but also all the virtual ones used by KVM, so everyone qualifies).
-
-Contact: Daniel Vetter, Thierry Reding, respective driver maintainers

-
Remove custom dumb_map_offset implementations

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The 50 ms default timeout waiting for vblanks is too small
for the first vblank from the ST-Ericsson MCDE display
controller over DSI. Presumably this is because the DSI
display is command-mode only and the state machine will
take some time setting up its state for the first display
update, and we hit a timeout. 100 ms makes it pass without
problems.

Subject: [PATCH 052/148] drm/scheduler: rework job destruction
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
We now destroy finished jobs from the worker thread to make sure that
we never destroy a job currently in timeout processing.
By this we avoid holding lock around ring mirror list in drm_sched_stop
which should solve a deadlock reported by a user.
v2: Remove unused variable.
v4: Move guilty job free into sched code.
v5:
Move sched->hw_rq_count to drm_sched_start to account for counter
decrement in drm_sched_stop even when we don't call resubmit jobs
if guily job did signal.
v6: remove unused variable

job.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Problem:
Sched thread's cleanup function races against TO handler
and removes the guilty job from mirror list and we
have no way of differentiating if the job was removed from within the
TO handler or from the sched thread's clean-up function.
Fix:
Add a flag to scheduler to hint the TO handler that the guilty job needs
to be explicitly released.
v2: whitespace fix

Also reject TDRs if another one already running.
v2:
Stop all schedulers across device and entire XGMI hive before
force signaling HW fences.
Avoid passing job_signaled to helper fnctions to keep all the decision
making about skipping HW reset in one place.
v3:
Fix SW sched. hang after non HW reset. sched.hw_rq_count has to be balanced
against it's decrement in drm_sched_stop in non HW reset case.
v4: rebase

Subject: [PATCH 058/148] drm/virtio: set seqno for dma-fence
This is motivated by having meaningful ftrace events, but it also
fixes use cases where dma_fence_is_later is called, such as in
sync_file_merge.
In other drivers, fence creation and cmdbuf submission normally
happen atomically,
mutex_lock();
fence = dma_fence_create(..., ++timeline->seqno);
submit_cmdbuf();
mutex_unlock();
and have no such issue. But in our driver, because most ioctls
queue commands into ctrlq, we do not want to grab a lock. Instead,
we set seqno to 0 when a fence is created, and update it when the
command is finally queued and the seqno is known.

Subject: [PATCH 064/148] drm/virtio: Remove redundant return type
virtio_gpu_fence_emit() always returns 0, since it
has no error paths.
Consequently no calls for virtio_gpu_fence_emit()
use the return value, and it can be removed.

+HD702E lcd is FriendlyELEC developed eDP LCD panel with 800x1280
+resolution. It has built in Goodix, GT9271 captive touchscreen
+with backlight adjustable via PWM.
+
+Required properties:
+- compatible: should be "friendlyarm,hd702e"
+- power-supply: regulator to provide the supply voltage
+
+Optional properties:
+- backlight: phandle of the backlight device attached to the panel
+
+Optional nodes:
+- Video port for LCD panel input.
+
+This binding is compatible with the simple-panel binding, which is specified
+in simple-panel.txt in this directory.
+

Subject: [PATCH 069/148] drm: Some ocd in drm_file.c
Move the open helper around to avoid the forward decl, and give
drm_setup a drm_legacy_ prefix since it's all legacy stuff in there.
v2: Move drm_legacy_setup into drm_legacy_misc.c (Chris). The
counterpart in the form of drm_legacy_dev_reinit is there already too,
plus it fits perfectly into Dave's work of making DRIVER_LEGACY code
compile-time optional.

Subject: [PATCH 070/148] drm/fb-helper: Avoid race with DRM userspace
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
drm_fb_helper_is_bound() is used to check if DRM userspace is in control.
This is done by looking at the fb on the primary plane. By the time
fb-helper gets around to committing, it's possible that the facts have
changed.
Avoid this race by holding the drm_device->master_mutex lock while
committing. When DRM userspace does its first open, it will now wait
until fb-helper is done. The helper will stay away if there's a master.
Two igt tests fail with the new 'bail out if master' rule. Work around
this by relaxing this rule for drm_fb_helper_restore_fbdev_mode_unlocked()
until the tests have been fixed. Add todo entry for this.
Locking rule: Always take the fb-helper lock first.
v5: drm_fb_helper_restore_fbdev_mode_unlocked(): Use
restore_fbdev_mode_force()
v2:
- Remove drm_fb_helper_is_bound() (Daniel Vetter)
- No need to check fb_helper->dev->master in
drm_fb_helper_single_fb_probe(), restore_fbdev_mode() has the check.

From 85438a8ddf031f416758ecf8c080ff92075acb01 Mon Sep 17 00:00:00 2001
From: Thomas Zimmermann <tzimmermann@suse.de>
Date: Wed, 8 May 2019 10:26:11 +0200
Subject: [PATCH 073/148] drm: Add |struct drm_gem_vram_object| and helpers
The type |struct drm_gem_vram_object| implements a GEM object for simple
framebuffer devices with dedicated video memory. The BO is either located
in VRAM or system memory.
The implementation has been created from the respective code in ast,
bochs and mgag200. These drivers copy their implementation from each
other; except for the names of several data types. The helpers are
currently build with TTM, but this is considered an implementation
detail and may change in future updates.
v5:
* do WARN_ON_ONCE for pin-count mismatches
* allocate only 2 entries in placements array
v4:
* cleanups from checkpatch.pl
* removed several fixed-size types from interfaces
* DRM_VRAM_HELPER now selects DRM_TTM
* remove separate config option for GEM VRAM
v2:
* rename to |struct drm_gem_vram_object|
* move drm_is_gem_ttm() to a later patch in the series
* add drm_gem_vram_kmap_at()
* return is_iomem from kmap functions
* redefine TTM placement flags for public interface
* documentation fixes

Subject: [PATCH 076/148] drm: Add drm_gem_vram_fill_create_dumb() to create
dumb buffers
The helper function drm_gem_vram_fill_create_dumb() implements most of
struct drm_driver.dumb_create() for GEM-VRAM buffer objects. It's not a
full implementation of the callback, as several driver-specific parameters
are still required.

Subject: [PATCH 078/148] drm: Add VRAM MM, a simple memory manager for
dedicated VRAM
The VRAM MM memory manager is a helper library that manages dedicated video
memory of simple framebuffer devices. It is supported to be used with
struct drm_gem_vram_object, but does not depend on it.
The implementation is based on the respective code from ast, bochs, and
mgag200. These drivers share the exact same implementation except for type
names. The helpers are currently build with TTM. This may change in future
revisions.
v4:
* cleanups from checkpatch.pl
v2:
* renamed to struct drm_vram_mm
* add drm_vram_mm_mmap() helper
* documentation fixes

Subject: [PATCH 080/148] drm: Integrate VRAM MM into struct drm_device
There's now a pointer to struct drm_vram_mm stored in struct drm_device.
DRM drivers that use VRAM MM should use this field to refer to their
instance of the data structure. Appropriate helpers are now provided as
well.
Adding struct drm_vram_mm to struct drm_device further avoids wrappers
and boilerplate code in drivers. This patch implements default functions
for callbacks in struct drm_driver and struct file_operations that use
the struct drm_vram_mm stored in struct drm_device. Drivers that need to
provide their own implementations can still do so.
The patch also adds documentation for the VRAM helper library in general.
v5:
* set .llseek to no_llseek() from DRM_VRAM_MM_FILE_OPERATIONS
v4:
* cleanups from checkpatch.pl
* document VRAM helper library

+/**
+ * DOC: overview
+ *
+ * This library provides &struct drm_gem_vram_object (GEM VRAM), a GEM
+ * buffer object that is backed by video RAM. It can be used for
+ * framebuffer devices with dedicated memory. The video RAM can be
+ * managed with &struct drm_vram_mm (VRAM MM). Both data structures are
+ * supposed to be used together, but can also be used individually.
+ *
+ * With the GEM interface userspace applications create, manage and destroy
+ * graphics buffers, such as an on-screen framebuffer. GEM does not provide
+ * an implementation of these interfaces. It's up to the DRM driver to
+ * provide an implementation that suits the hardware. If the hardware device
+ * contains dedicated video memory, the DRM driver can use the VRAM helper
+ * library. Each active buffer object is stored in video RAM. Active
+ * buffer are used for drawing the current frame, typically something like
+ * the frame's scanout buffer or the cursor image. If there's no more space
+ * left in VRAM, inactive GEM objects can be moved to system memory.
+ *
+ * The easiest way to use the VRAM helper library is to call
+ * drm_vram_helper_alloc_mm(). The function allocates and initializes an
+ * instance of &struct drm_vram_mm in &struct drm_device.vram_mm . Use
+ * &DRM_GEM_VRAM_DRIVER to initialize &struct drm_driver and
+ * &DRM_VRAM_MM_FILE_OPERATIONS to initialize &struct file_operations;
+ * as illustrated below.
+ *
+ * .. code-block:: c
+ *
+ * struct file_operations fops ={
+ * .owner = THIS_MODULE,
+ * DRM_VRAM_MM_FILE_OPERATION
+ * };
+ * struct drm_driver drv = {
+ * .driver_feature = DRM_ ... ,
+ * .fops = &fops,
+ * DRM_GEM_VRAM_DRIVER
+ * };
+ *
+ * int init_drm_driver()
+ * {
+ * struct drm_device *dev;
+ * uint64_t vram_base;
+ * unsigned long vram_size;
+ * int ret;
+ *
+ * // setup device, vram base and size
+ * // ...
+ *
+ * ret = drm_vram_helper_alloc_mm(dev, vram_base, vram_size,
+ * &drm_gem_vram_mm_funcs);
+ * if (ret)
+ * return ret;
+ * return 0;
+ * }
+ *
+ * This creates an instance of &struct drm_vram_mm, exports DRM userspace
+ * interfaces for GEM buffer management and initializes file operations to
+ * allow for accessing created GEM buffers. With this setup, the DRM driver
+ * manages an area of video RAM with VRAM MM and provides GEM VRAM objects
+ * to userspace.
+ *
+ * To clean up the VRAM memory management, call drm_vram_helper_release_mm()
+ * in the driver's clean-up code.
+ *
+ * .. code-block:: c
+ *
+ * void fini_drm_driver()
+ * {
+ * struct drm_device *dev = ...;
+ *
+ * drm_vram_helper_release_mm(dev);
+ * }
+ *
+ * For drawing or scanout operations, buffer object have to be pinned in video
+ * RAM. Call drm_gem_vram_pin() with &DRM_GEM_VRAM_PL_FLAG_VRAM or
+ * &DRM_GEM_VRAM_PL_FLAG_SYSTEM to pin a buffer object in video RAM or system
+ * memory. Call drm_gem_vram_unpin() to release the pinned object afterwards.
+ * If you have to evict a buffer object from video RAM (e.g., for freeing up
+ * memory), unpin the buffer and call drm_gem_vram_push_to_system().
+ *
+ * A buffer object that is pinned in video RAM has a fixed address within that
+ * memory region. Call drm_gem_vram_offset() to retrieve this value. Typically
+ * it's used to program the hardware's scanout engine for framebuffers, set
+ * the cursor overlay's image for a mouse cursor, or use it as input to the
+ * hardware's draing engine.
+ *
+ * To access a buffer object's memory from the DRM driver, call
+ * drm_gem_vram_kmap(). It (optionally) maps the buffer into kernel address
+ * space and returns the memory address. Use drm_gem_vram_kunmap() to
+ * release the mapping.

From 5b3709793d151e6e12eb6a38a5da3f7fc2923d3a Mon Sep 17 00:00:00 2001
From: Thomas Zimmermann <tzimmermann@suse.de>
Date: Wed, 8 May 2019 10:26:19 +0200
Subject: [PATCH 081/148] drm/ast: Convert AST driver to |struct
drm_gem_vram_object|
The data structure |struct drm_gem_vram_object| and its helpers replace
|struct ast_bo|. It's the same implementation; except for the type names.
v4:
* cleanups from checkpatch.pl

Subject: [PATCH 082/148] drm/ast: Convert AST driver to VRAM MM
The data structure |struct drm_vram_mm| and its helpers replace ast's
TTM-based memory manager. It's the same implementation; except for the
type names.
v4:
* don't select DRM_TTM or DRM_VRAM_MM_HELPER
v3:
* use drm_gem_vram_mm_funcs
* convert driver to drm_device-based instance
v2:
* implement ast_mmap() with drm_vram_mm_mmap()

Subject: [PATCH 083/148] drm/ast: Replace mapping code with
drm_gem_vram_{kmap/kunmap}()
The AST driver establishes several memory mappings for frame buffers
and cursors. This patch converts the driver to use the equivalent
drm_gem_vram_kmap() functions. It removes the dependencies on TTM
and cleans up the code.

From: Thomas Zimmermann <tzimmermann@suse.de>
Date: Wed, 8 May 2019 10:26:22 +0200
Subject: [PATCH 084/148] drm/bochs: Convert bochs driver to |struct
drm_gem_vram_object|
The data structure |struct drm_gem_vram_object| and its helpers replace
|struct bochs_bo|. It's the same implementation; except for the type
names.
v5:
* use PRIME helpers from GEM VRAM
v4:
* cleanups from checkpatch.pl
* select config option DRM_VRAM_HELPER
Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de>

Subject: [PATCH 085/148] drm/bochs: Convert bochs driver to VRAM MM
The data structure |struct drm_vram_mm| and its helpers replace bochs'
TTM-based memory manager. It's the same implementation; except for the
type names.
v5:
* set .llseek via DRM_VRAM_MM_FILE_OPERATIONS
v4:
* don't select DRM_TTM or DRM_VRAM_MM_HELPER
v3:
* use drm_gem_vram_mm_funcs
* convert driver to drm_device-based instance
v2:
* implement bochs_mmap() with drm_vram_mm_mmap()

Subject: [PATCH 087/148] drm/mgag200: Convert mgag200 driver to VRAM MM
The data structure |struct drm_vram_mm| and its helpers replace mgag200's
TTM-based memory manager. It's the same implementation; except for the type
names.
v4:
* don't select DRM_TTM or DRM_VRAM_MM_HELPER
v3:
* use drm_gem_vram_mm_funcs
* convert driver to drm_device-based instance
v2:
* implement mgag200_mmap() with drm_vram_mm_mmap()

Subject: [PATCH 088/148] drm/mgag200: Replace mapping code with
drm_gem_vram_{kmap/kunmap}()
The mgag200 driver establishes several memory mappings for frame buffers
and cursors. This patch converts the driver to use the equivalent
drm_gem_vram_kmap() functions. It removes the dependencies on TTM
and cleans up the code.
v4:
* cleanups from checkpatch.pl

Subject: [PATCH 089/148] drm/vboxvideo: Convert vboxvideo driver to |struct
drm_gem_vram_object|
This patch replaces |struct vbox_bo| and its helpers with the generic
implementation of |struct drm_gem_vram_object|. The only change in
semantics is that &ttm_bo_driver.verify_access() now does the actual
verification.
v4:
* select config option DRM_VRAM_HELPER
v3:
* remove forward declaration of struct vbox_gem_object
v2:
nothing

Subject: [PATCH 090/148] drm/vboxvideo: Convert vboxvideo driver to VRAM MM
The data structure |struct drm_vram_mm| and its helpers replace vboxvideo's
TTM-based memory manager. It's the same implementation; except for the type
names.
v4:
* don't select DRM_TTM or DRM_VRAM_MM_HELPER
v3:
* use drm_gem_vram_mm_funcs
* convert driver to drm_device-based instance
v2:
* implement vbox_mmap() with drm_vram_mm_mmap()

Subject: [PATCH 092/148] drm/hisilicon: Convert hibmc-drm driver to VRAM MM
The data structure |struct drm_vram_mm| and its helpers replace hibmc's
TTM-based memory manager. It's the same implementation; except for the
type names.
v5:
* set .llseek via DRM_VRAM_MM_FILE_OPERATIONS
v4:
* don't select DRM_TTM or DRM_VRAM_MM_HELPER
v3:
* use drm_gem_vram_mm_funcs
* convert driver to drm_device-based instance
v2:
* implement hibmc_mmap() with drm_vram_mm_mmap()

GENERIC_SHORT_WRITE_2 transfer
Some DSI panels do use GENERIC_SHORT_WRITE_2 transfer protocol to host

Add support for the same transfer, so-that so-that the panels which are
requesting similar transfer type will process properly.

Content-Transfer-Encoding: 8bit
drm_fb_helper_hotplug_event() should tolerate the fb_helper argument being
NULL. Commit 03a9606e7fee ("drm/fb-helper: Avoid race with DRM userspace")
introduced a fb_helper dereference before the NULL check.
Fixup by moving the dereference after the NULL check.

Subject: [PATCH 095/148] drm/doc: Allow new UAPI to be used once it's in
drm-next/drm-misc-next.
I was trying to figure out if it was permissible to merge the Mesa
side of V3D's CSD support yet while it's in drm-misc-next but not
drm-next, and developers on #dri-devel IRC had differing opinions of
what the requirement was.
v2: Restrict to just drm-next or drm-misc-next on airlied's request.

Subject: [PATCH 096/148] drm/doc: Document expectation that userspace review
looks at kernel uAPI.
The point of this review process is that userspace using the new uAPI
can actually live with the uAPI being provided, and it's hard to know
that without having actually looked into a kernel patch yourself.

Subject: [PATCH 100/148] drm/v3d: Fix and extend MMU error handling.
We were setting the wrong flags to enable PTI errors, so we were
seeing reads to invalid PTEs show up as write errors. Also, we
weren't turning on the interrupts. The AXI IDs we were dumping
included the outstanding write number and so they looked basically
random. And the VIO_ADDR decoding was based on the MMU VA_WIDTH for
the first platform I worked on and was wrong on others. In short,
this was a thorough mess from early HW enabling.
Tested on V3D 4.1 and 4.2 with intentional L2T, CLE, PTB, and TLB
faults.

Subject: [PATCH 101/148] drm: Fix drm.h uapi header for GNU/kFreeBSD
Like GNU/Linux, GNU/kFreeBSD's sys/types.h does not define the uintX_t
types, which differs from the BSDs' headers. Thus we should include
stdint.h to ensure we have all the required integer types.

Subject: [PATCH 104/148] drm: Add drm_gem_vram_{pin/unpin}_reserved() and
convert mgag200
The new interfaces drm_gem_vram_{pin/unpin}_reserved() are variants of the
GEM VRAM pin/unpin functions that do not reserve the BO during validation.
The mgag200 driver requires this behavior for its cursor handling. The
patch also converts the driver to use the new interfaces.

Subject: [PATCH 105/148] drm: Reserve/unreserve GEM VRAM BOs from within
pin/unpin functions
The original bochs and vbox implementations of pin and unpin functions
automatically reserved BOs during validation. This functionality got lost
while converting the code to a generic implementation. This may result
in validating unlocked TTM BOs.
Adding the reserve and unreserve operations to GEM VRAM's pin and unpin
functions fixes the bochs and vbox drivers. Additionally the patch changes
the mgag200, ast and hibmc drivers to not reserve BOs by themselves.

Subject: [PATCH 107/148] drm/rockchip: Change the scl_vop_cal_scl_fac to pass
drm_format_info
The Rockchip VOP driver has a function, scl_vop_cal_scl_fac, that will
lookup the drm_format_info structure from the fourcc passed to it by its
caller.
However, its only caller already derefences the drm_format_info structure
it has access to to retrieve that fourcc. Change the prototype of that
function to pass the drm_format_info structure directly, removing the need
for an extra lookup.

Subject: [PATCH 108/148] drm: Remove users of drm_format_num_planes
drm_format_num_planes() is basically a lookup in the drm_format_info table
plus an access to the num_planes field of the appropriate entry.
Most drivers are using this function while having access to the entry
already, which means that we will perform an unnecessary lookup. Removing
the call to drm_format_num_planes is therefore more efficient.
Some drivers will not have access to that entry in the function, but in
this case the overhead is minimal (we just have to call drm_format_info()
to perform the lookup) and we can even avoid multiple, inefficient lookups
in some places that need multiple fields from the drm_format_info
structure.

Subject: [PATCH 109/148] drm: Remove users of
drm_format_(horz|vert)_chroma_subsampling
drm_format_horz_chroma_subsampling and drm_format_vert_chroma_subsampling
are basically a lookup in the drm_format_info table plus an access to the
hsub and vsub fields of the appropriate entry.
Most drivers are using this function while having access to the entry
already, which means that we will perform an unnecessary lookup. Removing
the call to these functions is therefore more efficient.
Some drivers will not have access to that entry in the function, but in
this case the overhead is minimal (we just have to call drm_format_info()
to perform the lookup) and we can even avoid multiple, inefficient lookups
in some places that need multiple fields from the drm_format_info
structure.
This is amplified by the fact that most of the time the callers will have
to retrieve both the vsub and hsub fields, meaning that they would perform
twice the lookup.

Subject: [PATCH 110/148] drm/fourcc: Pass the format_info pointer to
drm_format_plane_cpp
So far, the drm_format_plane_cpp function was operating on the format's
fourcc and was doing a lookup to retrieve the drm_format_info structure and
return the cpp.
However, this is inefficient since in most cases, we will have the
drm_format_info pointer already available so we shouldn't have to perform a
new lookup. Some drm_fourcc functions also already operate on the
drm_format_info pointer for that reason, so the API is quite inconsistent
there.
Let's follow the latter pattern and remove the extra lookup while being a
bit more consistent. In order to be extra consistent, also rename that
function to drm_format_info_plane_cpp and to a static function in the
header to match the current policy.

Subject: [PATCH 111/148] drm/fourcc: Pass the format_info pointer to
drm_format_plane_width/height
So far, the drm_format_plane_height/width functions were operating on the
format's fourcc and was doing a lookup to retrieve the drm_format_info
structure and return the cpp.
However, this is inefficient since in most cases, we will have the
drm_format_info pointer already available so we shouldn't have to perform a
new lookup. Some drm_fourcc functions also already operate on the
drm_format_info pointer for that reason, so the API is quite inconsistent
there.
Let's follow the latter pattern and remove the extra lookup while being a
bit more consistent.
In order to be extra consistent, also rename that function to
drm_format_info_plane_cpp and to a static function in the header to match
the current policy. The parameters order have also be changed to match the
other functions prototype.

Subject: [PATCH 112/148] drm: Replace instances of drm_format_info by
drm_get_format_info
drm_get_format_info directly calls into drm_format_info, but takes directly
a struct drm_mode_fb_cmd2 pointer, instead of the fourcc directly. It's
shorter to not dereference it, and we can customise the behaviour at the
driver level if we want to, so let's switch to it where it makes sense.

Since it's pretty trivial, let's remove the function and have the users use

Subject: [PATCH 116/148] drm/lima: add timeout to drm scheduler init
After "5918045c4ed4 drm/scheduler: rework job destruction", lima started
to leak memory due to buffers not being destroyed after job execution in
the drm scheduler.
This started happening because the drm scheduler only destroyed buffers
after cancelling the job timeout handler, and for lima this handler was
never started as lima specified a MAX_SCHEDULE_TIMEOUT timeout.
Lima seems to run well in its current state with a real timeout, so to
make it more aligned with the other drivers from now on, let's use a
real default timeout.
This also fixes the observed memory leaks.
The 500ms value was chosen as it is the current value for all other
embedded gpu drivers using drm sched.

MIME-Version: 1.0

Content-Transfer-Encoding: 8bit
After "5918045c4ed4 drm/scheduler: rework job destruction", jobs are
only deleted when the timeout handler is able to be cancelled
successfully.
In case no timeout handler is running (timeout == MAX_SCHEDULE_TIMEOUT),
job cleanup would be skipped which may result in memory leaks.
Add the handling for the (timeout == MAX_SCHEDULE_TIMEOUT) case in
drm_sched_cleanup_jobs.

Subject: [PATCH 121/148] drm: Replace drm_gem_vram_push_to_system() with
kunmap + unpin
The push-to-system function forces a buffer out of video RAM. This decision
should rather be made by the memory manager. By replacing the function with
calls to the kunmap and unpin functions, the buffer's memory becomes available,
but the buffer remains in VRAM until it's evicted by a pin operation.
This patch replaces the remaining instances of drm_gem_vram_push_to_system()
in ast and mgag200, and removes the function from DRM.

Subject: [PATCH 122/148] drm: Rename reserve/unreserve to lock/unlock in GEM
VRAM helpers
To align with the rest of DRM terminology, the GEM VRAM helpers now use
lock and unlock in places where reserve and unreserve where used before.
All callers have been adapted.

Subject: [PATCH 123/148] drm: Assert that BO is locked in drm_gem_vram_{pin,
unpin}_locked()
We may not call drm_gem_vram_{pin,unpin}_locked() with an unlocked
BO. Now test for this.

Subject: [PATCH 125/148] drm/gma500: drop drmP.h from header files
Drop use of drmp.h from all header files in drm/gma500.
Fix fallout in all files.
In some cases moved include lines and sorted them too.
With drmP.h removed from all header files it can now be removed from
each .c file without any further dependencies

Subject: [PATCH 126/148] drm/gma500: make local header files more
self-contained
Add proper forward declarations to minimize dependencies on
other header files.
Just add enough that we can safely include all header files in
alphabetically order in relevant files.

Subject: [PATCH 127/148] drm/gma500: drop use of DRM_UDELAY wrapper
The DRM_UDELAY wrapper from drm_os_linux.h is used in a few places,
all other places calls udelay() with no wrapper.
There is no reason to continue to use this wrapper - so drop it
and direct call udelay().

Subject: [PATCH 128/148] drm/gma500: drop drmp.h include from all .c files
Drop remaining uses of the deprecated drmP.h in gma500
Replaced drmp.h with forward declarations or include files
as relevant.
Moved all include files to blocks in following order:
\#include <linux/*>
\#include <asm/*>
\#include <drm/*>
\#include ""
And within each block sort the include files alphabetically.

Subject: [PATCH 133/148] drm: Add HDR source metadata property
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This patch adds a blob property to get HDR metadata
information from userspace. This will be send as part
of AVI Infoframe to panel.
It also implements get() and set() functions for HDR output
metadata property.The blob data is received from userspace and
saved in connector state, the same is returned as blob in get
property call to userspace.
v2: Rebase and modified the metadata structure elements
as per Ville's POC changes.
v3: No Change
v4: Addressed Shashank's review comments
v5: Rebase.
v6: Addressed Brian Starkey's review comments, defined
new structure with header for dynamic metadata scalability.
Merge get/set property functions for metadata in this patch.
v7: Addressed Jonas Karlman review comments and defined separate
structure for infoframe to better align with CTA 861.G spec. Added
Shashank's RB.
v8: Addressed Ville's review comments. Moved sink metadata structure
out of uapi headers as suggested by Jonas Karlman.
v9: Rebase and addressed Jonas Karlman review comments.
v10: Addressed Ville's review comments, dropped the metdata_changed
state variable as its not needed anymore.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This adds reference count for HDR metadata blob,
handled as part of duplicate and destroy connector
state functions.
v2: Removed the hdr_metadata_changed initialization as
the variable is dropped and not required.

Subject: [PATCH 136/148] drm: Enable HDR infoframe support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Enable Dynamic Range and Mastering Infoframe for HDR
content, which is defined in CEA 861.3 spec.
The metadata will be computed based on blending
policy in userspace compositors and passed as a connector
property blob to driver. The same will be sent as infoframe
to panel which support HDR.
Added the const version of infoframe for DRM metadata
for HDR.
v2: Rebase and added Ville's POC changes.
v3: No Change
v4: Addressed Shashank's review comments and merged the
patch making drm infoframe function arguments as constant.
v5: Rebase
v6: Fixed checkpatch warnings with --strict option. Addressed
Shashank's review comments and added his RB.
v7: Addressed Brian Starkey's review comments. Merged 2 patches
into one.
v8: Addressed Jonas Karlman review comments.
v9: Addressed Jonas Karlman review comments.
v10: Addressed Ville's review comments.
v11: Added BUILD_BUG_ON and sizeof instead of magic numbers as
per Ville's comments.

Subject: [PATCH 137/148] drm: Add HLG EOTF
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
ADD HLG EOTF to the list of EOTF transfer functions supported.
Hybrid Log-Gamma (HLG) is a high dynamic range (HDR) standard.
HLG defines a nonlinear transfer function in which the lower
half of the signal values use a gamma curve and the upper half
of the signal values use a logarithmic curve.
v2: Rebase
v3: Fixed a warning message
v4: Addressed Shashank's review comments
v5: Addressed Jonas Karlman's review comment and dropped the i915
tag from header.

Fixes the following build warning:
drivers/gpu/drm/mediatek/mtk_hdmi.c:327:2: warning: enumeration value ‘HDMI_INFOFRAME_TYPE_DRM’ not handled in switch [-Wswitch]
Introduced with the addition of HDMI_INFOFRAME_TYPE_DRM in the commit
below, but the code really should have been future-proofed from the
start.

Subject: [PATCH 146/148] drm/vc4: Allocate binner bo when starting to use the
V3D
The binner BO is not required until the V3D is in use, so avoid
allocating it at probe and do it on the first non-dumb BO allocation.
Keep track of which clients are using the V3D and liberate the buffer
when there is none left, using a kref. Protect the logic with a
mutex to avoid race conditions.
The binner BO is created at the time of the first render ioctl and is
destroyed when there is no client and no exec job using it left.
The Out-Of-Memory (OOM) interrupt also gets some tweaking, to avoid
enabling it before having allocated a binner bo.
We also want to keep the BO alive during runtime suspend/resume to avoid
failing to allocate it at resume. This happens when the CMA pool is
