Subject: [PATCH 02/34] drm/i915: Move the SDP split debug spew to the correct
 place
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

Adding ad-hoc debug prints all over the place is not good.
Move the SDP split debug spew into the proper place (state
dumper).

Subject: [PATCH 03/34] drm/i915/psr: Move plane sel fetch configuration into
 plane source files
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently selective fetch configuration for planes is implemented in psr
code. More suitable place for this code is where everything else is
configured for planes -> move it into skl_universal_plane.c and
intel_cursor.c. This also allows us to drop hooks for cursor handling.

v3: Checkpatch warnings fixed
v2: Removed setting sel_fetch_area->y1/y2 as -1

Subject: [PATCH 04/34] drm/i915/psr: Add proper handling for disabling sel
 fetch for planes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently we are enabling selective fetch for all planes that are visible.
This is suboptimal as we might be fetching for memory for planes that are
not part of selective update.

Fix this by adding proper handling for disabling plane selective fetch:
If plane previously part of selective update is now not part of update:
Add it into updated planes and let the plane configuration to disable
selective fetch for it.

v3: Checkpatch warnings fixed
v2:
  - Add setting sel_fetch_area->y1/y2 to -1
  - Remove setting again local sel_fetch_area variable

 enabled

In earlier versions, FBC was restricted if PSR2 is enabled. From
xe2lpd onwards no such restrictions are needed anymore.

Currently no one can figure out what the PSR code is doing since
we're including any of it in the basic state dump. Add at least the
bare minimum there.

v2: Also dump has_panel_replay (Jouni)

Subject: [PATCH 07/34] drm/i915: Skip some timing checks on BXT/GLK DSI
 transcoders
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Apparently some BXT/GLK systems have DSI panels whose timings
don't agree with the normal cpu transcoder hblank>=32 limitation.
This is perhaps fine as there are no specific hblank/etc. limits
listed for the BXT/GLK DSI transcoders.

Move those checks out from the global intel_mode_valid() into
into connector specific .mode_valid() hooks, skipping BXT/GLK
DSI connectors. We'll leave the basic [hv]display/[hv]total
checks in intel_mode_valid() as those seem like sensible upper
limits regardless of the transcoder used.

Subject: [PATCH 09/34] drm/i915/mst: Reject modes that require the bigjoiner
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We have no bigjoiner support in the MST code, so .mode_valid()
pretending otherwise is just going to result black screens for
users. Reject any mode that needs the joiner.

Use the >= and < operators for the DISPLAY_VER checks everywhere.
This is what most of the code does, but especially recently random
pieces of code have started doing this differently for no good reason.

Conversion done with the following cocci:

DISPLAY_VER(i915) > ver
)

@script:python inc@

new_ver;
@@
coccinelle.new_ver = str(int(old_ver) + 1)

when _intel_dsb_commit function is called by intel_dsb_commit function,
the dewake_scanline variable may have an int value.
So the dewake_scanline variable is necessary to defined as an int.

Subject: [PATCH 17/34] drm/i915/display: Skip state verification with TBT-ALT
 mode

With TBT-ALT mode we are not programming C20 chip PLL's and
hence we don't need to check state verification. We don't
need to program DP link signal levels i.e.pre-emphasis and
voltage swing either.

This patch fixes dmesg errors like this one

"[drm] ERROR PHY F Write 0c06 failed after 3 retries."

We are preparing for Xe driver. I915 and Xe object implementation are
differing. Do not use  i915_gem_object->base directly. Instead use
intel_bo_to_drm_bo.

Also use drm_gem_object_put instead of i915_gem_object_put. This should be
ok as i915_gem_object_put is really just doing 	__drm_gem_object_put.

Subject: [PATCH 23/34] drm/i915/display: Split i915 specific code away from
 intel_fb.c
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We are preparing for Xe driver. Backing object implementation is differing
between i915 and Xe. Split i915 specific code into separate source file
built only for i915.

v9:
  - Use ERR_CAST
v8:
  - return original error code from intel_fb_bo_lookup_valid_bo on failure
v7:
  - drop #include <drm/drm_plane.h>
  - s/user_mode_cmd/mode_cmd/
  - Use passed i915 pointer instead of to_i915(obj->base.dev)
v6: Add missing intel_fb_bo.[ch]
v5:
  - Keep drm_any_plane_has_format check in intel_fb.c
  - Use mode_cmd instead of user_mode_cmd for intel_fb_bo_lookup_valid_bo
v4: Move drm_any_plane_has_format check into intel_fb_bo.c
v3: Fix failure handling in intel_framebuffer_init
v2: Couple of fixes to error value handling

Subject: [PATCH 26/34] drm/i915/dsi: Use devm_gpiod_get() for all GPIOs

soc_gpio_set_value() already uses devm_gpiod_get(), lets be consistent
and use devm_gpiod_get() for all GPIOs.

This allows removing the intel_dsi_vbt_gpio_cleanup() function,
which only function was to put the GPIO-descriptors.

Subject: [PATCH 27/34] drm/i915: Fix ADL+ tiled plane stride when the POT
 stride is smaller than the original
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

plane_view_scanout_stride() currently assumes that we had to pad the
mapping stride with dummy pages in order to align it. But that is not
the case if the original fb stride exceeds the aligned stride used
to populate the remapped view, which is calculated from the user
specified framebuffer width rather than the user specified framebuffer
stride.

Ignore the original fb stride in this case and just stick to the POT
aligned stride. Getting this wrong will cause the plane to fetch the
wrong data, and can lead to fault errors if the page tables at the
bogus location aren't even populated.

TODO: figure out if this is OK for CCS, or if we should instead increase
the width of the view to cover the entire user specified fb stride
instead...

Subject: [PATCH 28/34] drm/i915: handle uncore spinlock when not available
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The uncore code may not always be available (e.g. when we build the
display code with Xe), so we can't always rely on having the uncore's
spinlock.

To handle this, split the spin_lock/unlock_irqsave/restore() into
spin_lock/unlock() followed by a call to local_irq_save/restore() and
create wrapper functions for locking and unlocking the uncore's
spinlock.  In these functions, we have a condition check and only
actually try to lock/unlock the spinlock when I915 is defined, and
thus uncore is available.

This keeps the ifdefs contained in these new functions and all such
logic inside the display code.

Subject: [PATCH 34/34] drm/i915/display: Add intel_fb_bo_framebuffer_fini
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Xe needs intel_fb_bo_framebuffer_fini for taking care of unpinning the fb
and taking reference.  In i915 this can be empty.

Also move intel_frontbuffer_get to be done after
intel_fb_bo_framebuffer_init to have reasonable sequences:

intel_fb_bo_framebuffer_init
intel_frontbuffer_get
...
intel_frontbuffer_put
intel_fb_bo_framebuffer_fini

v2: Empty function instead of define
