* drm/i915: Enable guest i915 full ppgtt functionalityTina Zhang2017-08-155-3/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enable the guest i915 full ppgtt functionality when host can provide this capability. vgt_caps is introduced to guest i915 driver to get the vgpu capabilities from the device model. VGT_CPAS_FULL_PPGTT is one of the capabilities type to let guest i915 dirver know that the guest i915 full ppgtt is supported by device model. Notice that the minor version of pvinfo isn't bumped because of this vgt_caps introduction, due to older guest would be broken by simply increasing the pvinfo version. Although the pvinfo minor version doesn't increase, the compatibility won't be blocked. The compatibility is ensured by checking the value of caps field in pvinfo. Zero means no full ppgtt support and BIT(2) means this feature is provided. Changes since v1: - Use u32 instead of uint32_t (Joonas) - Move VGT_CAPS_FULL_PPGTT introduction to this patch and use #define instead of enum (Joonas) - Rewrite the vgpu full ppgtt capability checking logic. (Joonas) - Some coding style refine. (Joonas) Changes since v2: - Divide the whole patch set into two separate patch series, with one patch in i915 side to check guest i915 full ppgtt capability and enable it when this capability is supported by the device model, and the other one in gvt side which fixs the blocking issue and enables the device model to provide the capability to guest. And this patch focuses on guest i915 side. (Joonas) - Change the title from "introduce vgt_caps to pvinfo" to "Enable guest i915 full ppgtt functionality". (Tina) Change since v3: - Add some comments about pvinfo caps and version. (Joonas) Change since v4: - Tested by Tina Zhang. Change since v5: - Add limitation about supporting 32bit full ppgtt. Change since v6: - Change the fallback to 48bit full ppgtt if i915.ppgtt_enable=2. (Zhenyu) Change in v9: - Remove the fixme comment due to no plan for 32bit full ppgtt support. (Zhenyu) - Reorder the patch-set to fix compiling issue with git-bisect. (Zhenyu) - Add print log when forcing guest 48bit full ppgtt. (Zhenyu) v10: - Update against Joonas's has_full_ppgtt and has_full_48bit_ppgtt disconnect change.

* drm/i915/gvt: Add shadow context descriptor updatingKechen Lu2017-08-103-0/+26
| | | | | | | | | | | | | | | | | | | | The current context logic only updates the descriptor of context when it's being pinned to graphics memory space. But this cannot satisfy the requirement of shadow context. The addressing mode of the pinned shadow context descriptor may be changed according to the guest addressing mode. And this won't be updated, as the already pinned shadow context has no chance to update its descriptor. And this will lead to GPU hang issue, as shadow context is used with wrong descriptor. This patch fixes this issue by letting the pinned shadow context descriptor update its addressing mode on demand. This patch fixes GPU HANG issue which happends after changing the grub parameter i915.enable_ppgtt form 0x01 to 0x03 or vice versa and then rebooting the guest.

* drm/i915: Force CPU synchronisation even if userspace requests ASYNCChris Wilson2017-07-273-8/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The goal here was to minimise doing any thing or any check inside the kernel that was not strictly required. For a userspace that assumes complete control over the cache domains, the kernel is usually using outdated information and may trigger clflushes where none were required. However, swapping is a situation where userspace has no knowledge of the domain transfer, and will leave the object in the CPU cache. The kernel must flush this out to the backing storage prior to use with the GPU. As we use an asynchronous task tracked by an implicit fence for this, we also need to cancel the ASYNC flag on the object so that the object will wait for the clflush to complete before being executed. This also absolves userspace of the responsibility imposed by commit 77ae9957897d ("drm/i915: Enable userspace to opt-out of implicit fencing") that its needed to ensure that the object was out of the CPU cache prior to use on the GPU.

* drm/i915: Only skip updating execobject.offset after errorChris Wilson2017-07-271-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | I was being overly paranoid in not updating the execobject.offset after performing the fallback copy where we set reloc.presumed_offset to -1. The thinking was to ensure that a subsequent NORELOC execbuf would be forced to process the invalid relocations. However this is overkill so long as we *only* update the execobject.offset following a successful update of the relocation value witin the batch. If we have to repeat the execbuf due to a later interruption, then we may skip the relocations on the second pass (honouring NORELOC) since the execobject.offset match the actual offsets (even though reloc.presumed_offset is garbage). Subsequent calls to execbuf with NORELOC should themselves ensure that the reloc.presumed_offset have been corrected in case of future migration. Reporting back the actual execobject.offset, even when reloc.presumed_offset is garbage, ensures that reuse of those objects use the latest information to avoid relocations.

* drm/i915: add config function for YCBCR420 outputsShashank Sharma2017-07-273-3/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch checks encoder level support for YCBCR420 outputs. The logic goes as simple as this: If the input mode is YCBCR420-only mode: prepare HDMI for YCBCR420 output, else continue with RGB output mode. It checks if the mode is YCBCR420 and source can support this output then it marks the ycbcr_420 output indicator into crtc state, for further staging in driver. V2: Split the patch into two, kept helper functions in DRM layer. V3: Changed the compute_config function based on new DRM API. V4: Rebase V5: Rebase V6: Check and handle YCBCR420-only modes, discard the property based approach (Ville) V7: Addressed review comments from Ville - add else case in 12BPC check. - extract ycbcr420 state inside hdmi_12bpc_possible function. V8: Addressed review comments from Ville - Remove extra blank lines. - Remove "HDMI" from the description of ycbcr420 state variable. - Remove local variable, use crtc_state->ycbcr420 instead.

Using power well attributes instead of platform checks to decide whether to init/reset pipe IRQs and VGA correspondingly is cleaner and it allows us to unify the HSW/BDW and GEN9+ power well code in follow-up patches.
