Several ways for virtualization support were -proposed, paravirt_ops is the winner. -On the other hand, now there are also several IA64 virtualization -technologies like kvm/IA64, xen/IA64 and many other academic IA64 -hypervisors so that it is good to add generic virtualization -infrastructure on Linux/IA64. - - -What is paravirt_ops? ---------------------- -It has been developed on x86 as virtualization support via API, not ABI. -It allows each hypervisor to override operations which are important for -hypervisors at API level. And it allows a single kernel binary to run on -all supported execution environments including native machine. -Essentially paravirt_ops is a set of function pointers which represent -operations corresponding to low level sensitive instructions and high -level functionalities in various area. But one significant difference -from usual function pointer table is that it allows optimization with -binary patch. It is because some of these operations are very -performance sensitive and indirect call overhead is not negligible. -With binary patch, indirect C function call can be transformed into -direct C function call or in-place execution to eliminate the overhead. - -Thus, operations of paravirt_ops are classified into three categories. -- simple indirect call - These operations correspond to high level functionality so that the - overhead of indirect call isn't very important. - -- indirect call which allows optimization with binary patch - Usually these operations correspond to low level instructions. They - are called frequently and performance critical. So the overhead is - very important. - -- a set of macros for hand written assembly code - Hand written assembly codes (.S files) also need paravirtualization - because they include sensitive instructions or some of code paths in - them are very performance critical. - - -The relation to the IA64 machine vector ---------------------------------------- -Linux/IA64 has the IA64 machine vector functionality which allows the -kernel to switch implementations (e.g. initialization, ipi, dma api...) -depending on executing platform. -We can replace some implementations very easily defining a new machine -vector. Thus another approach for virtualization support would be -enhancing the machine vector functionality. -But paravirt_ops approach was taken because -- virtualization support needs wider support than machine vector does. - e.g. low level instruction paravirtualization. It must be - initialized very early before platform detection. - -- virtualization support needs more functionality like binary patch. - Probably the calling overhead might not be very large compared to the - emulation overhead of virtualization. However in the native case, the - overhead should be eliminated completely. - A single kernel binary should run on each environment including native, - and the overhead of paravirt_ops on native environment should be as - small as possible. - -- for full virtualization technology, e.g. KVM/IA64 or - Xen/IA64 HVM domain, the result would be - (the emulated platform machine vector. probably dig) + (pv_ops). - This means that the virtualization support layer should be under - the machine vector layer. - -Possibly it might be better to move some function pointers from -paravirt_ops to machine vector. In fact, Xen domU case utilizes both -pv_ops and machine vector. - - -IA64 paravirt_ops ------------------ -In this section, the concrete paravirt_ops will be discussed. -Because of the architecture difference between ia64 and x86, the -resulting set of functions is very different from x86 pv_ops. - -- C function pointer tables -They are not very performance critical so that simple C indirect -function call is acceptable. The following structures are defined at -this moment.

For details see -linux/include/asm-ia64/paravirt_privop.h -Mostly they correspond to ia64 intrinsics 1-to-1. -Caveat: Now they are defined as C indirect function pointers, but in -order to support binary patch optimization, they will be changed -using GCC extended inline assembly code. - -- a set of macros for hand written assembly code (.S files) -For maintenance purpose, the taken approach for .S files is single -source code and compile multiple times with different macros definitions. -Each pv_ops instance must define those macros to compile. -The important thing here is that sensitive, but non-privileged -instructions must be paravirtualized and that some privileged -instructions also need paravirtualization for reasonable performance. -Developers who modify .S files must be aware of that.

When a suspend request +fails, all suspended devices are resumed and the system continues +to run. Suspend can be retried at a later time. + +Q: Can the driver block suspend/resume requests? + +Yes, a driver can delay its return from a suspend or resume +request until the device is ready to handle requests. It +is advantageous to return as quickly as possible from a +request as suspend/resume are done serially. + +Q: What context is a suspend/resume initiated from? + +A suspend or resume is initiated from a kernel thread context. +It is safe to block, allocate memory, initiate requests +or anything else you can do within the kernel. + +Q: Will requests continue to arrive after a suspend? + +Possibly. It is the driver's responsibility to queue(*), +fail, or drop any requests that arrive after returning +success to a suspend request. It is important that the +driver not access its device until after it receives +a resume request as the device's bus may no longer +be active. + +(*) If a driver queues requests for processing after + resume be aware that the device, network, etc. + might be in a different state than at suspend time. + It's probably better to drop requests unless + the driver is a storage device. + +Q: Do I have to manage bus-specific power management registers + +No. It is the responsibility of the bus driver to manage +PCI, USB, etc. power management registers. The bus driver +or the power management subsystem will also enable any +wake-on functionality that the device has. + +Q: So, really, what do I need to do to support suspend/resume? + +You need to save any device context that would +be lost if the device was powered off and then restore +it at resume time. When ACPI is active, there are +three levels of device suspend states; D1, D2, and D3. +(The suspend state is passed as the "data" argument +to the device callback.) With D3, the device is powered +off and loses all context, D1 and D2 are shallower power +states and require less device context to be saved. To +play it safe, just save everything at suspend and restore +everything at resume. + +Q: Where do I store device context for suspend? + +Anywhere in memory, kmalloc a buffer or store it +in the device descriptor. You are guaranteed that the +contents of memory will be restored and accessible +before resume, even when the system suspends to disk. + +Q: What do I need to do for ACPI vs. APM vs. etc? + +Drivers need not be aware of the specific power management +technology that is active.

Prior to this KVM + initialization, we choose to map virtual to physical addresses + 1:1. That is, the kernel virtual address exactly matches the + physical address on the bus. These mappings are typically done + in arch/ppc/kernel/head.S, or arch/ppc/mm/init.c. Only + absolutely necessary mappings should be done at this time, for + example board control registers or a serial uart. Normal device + driver initialization should map resources later when necessary. + + Although platform dependent, and certainly the case for embedded + 8xx, traditionally memory is mapped at physical address zero, + and I/O devices above physical address 0x80000000. The lowest + and highest (above 0xf0000000) I/O addresses are traditionally + used for devices or registers we need to map during kernel + initialization and prior to KVM operation. For this reason, + and since it followed prior PowerPC platform examples, I chose + to map the embedded 8xx kernel to the 0xc0000000 virtual address. + This way, we can enable the MMU to map the kernel for proper + operation, and still map a few windows before the KVM is operational. + + On some systems, you could possibly run the kernel at the + 0x80000000 or any other virtual address. It just depends upon + mapping that must be done prior to KVM operational. You can never + map devices or kernel spaces that overlap with the user virtual + space. This is why default IMMR mapping used by most BDM tools + won't work. They put the IMMR at something like 0x10000000 or + 0x02000000 for example. You simply can't map these addresses early + in the kernel, and continue proper system operation. + + The embedded 8xx/82xx kernel is mature enough that all you should + need to do is map the IMMR someplace at or above 0xf0000000 and it + should boot far enough to get serial console messages and KGDB + connected on any platform.

Is there some compatibility to the old API? + +Yes, but only for control, bulk and interrupt transfers. We've implemented +some wrapper calls for these transfer types. The usbcore works fine with +these wrappers. For ISO there's no compatibility, because the old ISO-API +and its semantics were unnecessary complicated in our opinion. + +1.4. What's really working? + +As said above, CTRL and BULK already work fine even with the wrappers, +so legacy code wouldn't notice the change. +Regarding to Thomas, ISO transfers now run stable with USB audio. +INT transfers (e.g. mouse driver) work fine, too. + +1.5. Are there any bugs? + +No ;-) +Hm... +Well, of course this implementation needs extensive testing on all available +hardware, but we believe that any fixes shouldn't harm the overall concept. + +1.6. What should be done next? + +A large part of the request handling seems to be identical for UHCI and +OHCI, so it would be a good idea to extract the common parts and have only +the HW specific stuff in uhci.c. Furthermore, all other USB device drivers +should need URBification, if they use isochronous or interrupt transfers. +One thing missing in the current implementation (and the old UHCI driver) +is fair queueing for BULK transfers. Since this would need (in principle) +the alteration of already constructed TD chains (to switch from depth to +breadth execution), another way has to be found. Maybe some simple +heuristics work with the same effect. + +--------------------------------------------------------------------------- + +2. Internal structure and mechanisms + +To get quickly familiar with the internal structures, here's a short +description how the new UHCI driver works. However, the ultimate source of +truth is only uhci.c! + +2.1. Descriptor structure (QHs and TDs) + +During initialization, the following skeleton is allocated in init_skel: + + framespecific | common chain + +framelist[] +[ 0 ]-----> TD --> TD -------\ +[ 1 ]-----> TD --> TD --------> TD ----> QH -------> QH -------> QH ---> NULL + ... TD --> TD -------/ +[1023]-----> TD --> TD ------/ + + ^^ ^^ ^^ ^^ ^^ ^^ + 1024 TDs for 7 TDs for 1 TD for Start of Start of End Chain + ISO INT (2-128ms) 1ms-INT CTRL Chain BULK Chain + +For each CTRL or BULK transfer a new QH is allocated and the containing data +transfers are appended as (vertical) TDs. After building the whole QH with its +dangling TDs, the QH is inserted before the BULK Chain QH (for CTRL) or +before the End Chain QH (for BULK). Since only the QH->next pointers are +affected, no atomic memory operation is required. The three QHs in the +common chain are never equipped with TDs! + +For ISO or INT, the TD for each frame is simply inserted into the appropriate +ISO/INT-TD-chain for the desired frame. The 7 skeleton INT-TDs are scattered +among the 1024 frames similar to the old UHCI driver. + +For CTRL/BULK/ISO, the last TD in the transfer has the IOC-bit set. For INT, +every TD (there is only one...) has the IOC-bit set. + +Besides the data for the UHCI controller (2 or 4 32bit words), the descriptors +are double-linked through the .vertical and .horizontal elements in the +SW data of the descriptor (using the double-linked list structures and +operations), but SW-linking occurs only in closed domains, i.e. for each of +the 1024 ISO-chains and the 8 INT-chains there is a closed cycle. This +simplifies all insertions and unlinking operations and avoids costly +bus_to_virt()-calls. + +2.2. URB structure and linking to QH/TDs + +During assembly of the QH and TDs of the requested action, these descriptors +are stored in urb->urb_list, so the allocated QH/TD descriptors are bound to +this URB. +If the assembly was successful and the descriptors were added to the HW chain, +the corresponding URB is inserted into a global URB list for this controller. +This list stores all pending URBs. + +2.3. Interrupt processing + +Since UHCI provides no means to directly detect completed transactions, the +following is done in each UHCI interrupt (uhci_interrupt()): + +For each URB in the pending queue (process_urb()), the ACTIVE-flag of the +associated TDs are processed (depending on the transfer type +process_{transfer|interrupt|iso}()). If the TDs are not active anymore, +they indicate the completion of the transaction and the status is calculated. +Inactive QH/TDs are removed from the HW chain (since the host controller +already removed the TDs from the QH, no atomic access is needed) and +eventually the URB is marked as completed (OK or errors) and removed from the +pending queue. Then the next linked URB is submitted. After (or immediately +before) that, the completion handler is called. + +2.4. Unlinking URBs + +First, all QH/TDs stored in the URB are unlinked from the HW chain. +To ensure that the host controller really left a vertical TD chain, we +wait for one frame. After that, the TDs are physically destroyed. + +2.5. URB linking and the consequences + +Since URBs can be linked and the corresponding submit_urb is called in +the UHCI-interrupt, all work associated with URB/QH/TD assembly has to be +interrupt save.
