2021-10-04drm/i915: Clean up disabled warningsNathan Chancellor
i915 enables a wider set of warnings with '-Wall -Wextra' then disables several with cc-disable-warning. If an unknown flag gets added to KBUILD_CFLAGS when building with clang, all subsequent calls to cc-{disable-warning,option} will fail, meaning that all of these warnings do not get disabled [1]. A separate series will address the root cause of the issue by not adding these flags when building with clang [2]; however, the symptom of these extra warnings appearing can be addressed separately by just removing the calls to cc-disable-warning, which makes the build ever so slightly faster because the compiler does not need to be called as much before building. The following warnings are supported by GCC 4.9 and clang 10.0.1, which are the minimum supported versions of these compilers so the call to cc-disable-warning is not necessary. Masahiro cleaned this up for the reset of the kernel in commit 4c8dd95a723d ("kbuild: add some extra warning flags unconditionally"). * -Wmissing-field-initializers * -Wsign-compare * -Wtype-limits * -Wunused-parameter -Wunused-but-set-variable was implemented in clang 13.0.0 and -Wframe-address was implemented in clang 12.0.0 so the cc-disable-warning calls are kept for these two warnings. Lastly, -Winitializer-overrides is clang's version of -Woverride-init, which is disabled for the specific files that are problematic. clang added a compatibility alias in clang 8.0.0 so -Winitializer-overrides can be removed.

2021-10-04drm/i915/pxp: Enable PXP power managementHuang, Sean Z
During the power event S3+ sleep/resume, hardware will lose all the encryption keys for every hardware session, even though the session state might still be marked as alive after resume. Therefore, we should consider the session as dead on suspend and invalidate all the objects. The session will be automatically restarted on the first protected submission on resume. v2: runtime suspend also invalidates the keys v3: fix return codes, simplify rpm ops (Chris), use the new worker func v4: invalidate the objects on suspend, don't re-create the arb sesson on resume (delayed to first submission). v5: move irq changes back to irq patch (Rodrigo) v6: drop invalidation in runtime suspend (Rodrigo) Signed-off-by: Huang, Sean Z <sean.z.huang@intel.com> Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210924191452.1539378-13-alan.previn.teres.alexis@intel.com
2021-10-04drm/i915/pxp: Implement PXP irq handlerHuang, Sean Z
The HW will generate a teardown interrupt when session termination is required, which requires i915 to submit a terminating batch. Once the HW is done with the termination it will generate another interrupt, at which point it is safe to re-create the session. Since the termination and re-creation flow is something we want to trigger from the driver as well, use a common work function that can be called both from the irq handler and from the driver set-up flows, which has the addded benefit of allowing us to skip any extra locks because the work itself serializes the operations. v2: use struct completion instead of bool (Chris) v3: drop locks, clean up functions and improve comments (Chris), move to common work function. v4: improve comments, simplify wait logic (Rodrigo) v5: unconditionally set interrupts, rename state_attacked var (Rodrigo) v10: remove inclusion of intel_gt_types.h from intel_pxp.h (Jani) Signed-off-by: Alan Previn <alan.previn.teres.alexis@intel.com> Signed-off-by: Huang, Sean Z <sean.z.huang@intel.com> Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210924191452.1539378-10-alan.previn.teres.alexis@intel.com

2021-10-04drm/i915/pxp: Create the arbitrary session after bootHuang, Sean Z
Create the arbitrary session, with the fixed session id 0xf, after system boot, for the case that application allocates the protected buffer without establishing any protection session. Because the hardware requires at least one alive session for protected buffer creation. This arbitrary session will need to be re-created after teardown or power event because hardware encryption key won't be valid after such cases. The session ID is exposed as part of the uapi so it can be used as part of userspace commands. v2: use gt->uncore->rpm (Chris) v3: s/arb_is_in_play/arb_is_valid (Chris), move set-up to the new init_hw function v4: move interface defs to separate header, set arb_is valid to false on fini (Rodrigo) v5: handle async component binding Signed-off-by: Huang, Sean Z <sean.z.huang@intel.com> Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210924191452.1539378-8-alan.previn.teres.alexis@intel.com

2021-09-24drm/i915 Implement LMEM backup and restore for suspend / resumeThomas Hellström
Just evict unpinned objects to system. For pinned LMEM objects, make a backup system object and blit the contents to that. Backup is performed in three steps, 1: Opportunistically evict evictable objects using the gpu blitter. 2: After gt idle, evict evictable objects using the gpu blitter. This will be modified in an upcoming patch to backup pinned objects that are not used by the blitter itself. 3: Backup remaining pinned objects using memcpy. Also move uC suspend to after 2) to make sure we have a functional GuC during 2) if using GuC submission. v2: - Major refactor to make sure gem_exec_suspend@hang-SX subtests work, and suspend / resume works with a slightly modified GuC submission enabling patch series. v3: - Fix a potential use-after-free (Matthew Auld) - Use i915_gem_object_create_shmem() instead of i915_gem_object_create_region (Matthew Auld) - Minor simplifications (Matthew Auld) - Fix up kerneldoc for i195_ttm_restore_region(). - Final lmem_suspend() call moved to i915_gem_backup_suspend from i915_gem_suspend_late, since the latter gets called at driver unload and we don't unnecessarily want to run it at that time. v4: - Interface change of ttm- & lmem suspend / resume functions to use flags rather than bools.

2021-08-03drm/i915/guc/rc: Setup and enable GuCRC featureVinay Belgaumkar
This feature hands over the control of HW RC6 to the GuC. GuC decides when to put HW into RC6 based on it's internal busyness algorithms. GuCRC needs GuC submission to be enabled, and only supported on Gen12+ for now. When GuCRC is enabled, do not set HW RC6. Use a H2G message to tell GuC to enable GuCRC. When disabling RC6, tell GuC to revert RC6 control back to KMD. KMD is still responsible for enabling everything related to Coarse Power Gating though. v2: Address comments (Michal W) v3: Don't set hysterisis values when GuCRC is used (Matt Roper) v4: checkpatch() Reviewed-by: Michal Wajdeczko <michal.wajdeczko@intel.com> Signed-off-by: Vinay Belgaumkar <vinay.belgaumkar@intel.com> Signed-off-by: John Harrison <John.C.Harrison@Intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210730202119.23810-15-vinay.belgaumkar@intel.com

2021-07-28drm/i915: Extract i915_module.cDaniel Vetter
The module init code is somewhat misplaced in i915_pci.c, since it needs to pull in init/exit functions from every part of the driver and pollutes the include list a lot. Extract an i915_module.c file which pulls all the bits together, and allows us to massively trim the include list of i915_pci.c. The downside is that have to drop the error path check Jason added to catch when we set up the pci driver too early. I think that risk is acceptable for this pretty nice include.

2021-07-08drm/i915: Drop I915_CONTEXT_PARAM_RINGSIZEJason Ekstrand
This reverts commit 88be76cdafc7 ("drm/i915: Allow userspace to specify ringsize on construction"). This API was originally added for OpenCL but the compute-runtime PR has sat open for a year without action so we can still pull it out if we want. I argue we should drop it for three reasons: 1. If the compute-runtime PR has sat open for a year, this clearly isn't that important. 2. It's a very leaky API. Ring size is an implementation detail of the current execlist scheduler and really only makes sense there. It can't apply to the older ring-buffer scheduler on pre-execlist hardware because that's shared across all contexts and it won't apply to the GuC scheduler that's in the pipeline. 3. Having userspace set a ring size in bytes is a bad solution to the problem of having too small a ring. There is no way that userspace has the information to know how to properly set the ring size so it's just going to detect the feature and always set it to the maximum of 512K. This is what the compute-runtime PR does. The scheduler in i915, on the other hand, does have the information to make an informed choice. It could detect if the ring size is a problem and grow it itself. Or, if that's too hard, we could just increase the default size from 16K to 32K or even 64K instead of relying on userspace to do it. Let's drop this API for now and, if someone decides they really care about solving this problem, they can do it properly.

2021-06-17drm/i915/gt: Pipelined page migrationChris Wilson
If we pipeline the PTE updates and then do the copy of those pages within a single unpreemptible command packet, we can submit the copies and leave them to be scheduled without having to synchronously wait under a global lock. In order to manage migration, we need to preallocate the page tables (and keep them pinned and available for use at any time), causing a bottleneck for migrations as all clients must contend on the limited resources. By inlining the ppGTT updates and performing the blit atomically, each client only owns the PTE while in use, and so we can reschedule individual operations however we see fit. And most importantly, we do not need to take a global lock on the shared vm, and wait until the operation is complete before releasing the lock for others to claim the PTE for themselves.

2021-06-11drm/i915/ttm: Introduce a TTM i915 gem object backendThomas Hellström
Most logical place to introduce TTM buffer objects is as an i915 gem object backend. We need to add some ops to account for added functionality like delayed delete and LRU list manipulation. Initially we support only LMEM and SYSTEM memory, but SYSTEM (which in this case means evicted LMEM objects) is not visible to i915 GEM yet. The plan is to move the i915 gem system region over to the TTM system memory type in upcoming patches. We set up GPU bindings directly both from LMEM and from the system region, as there is no need to use the legacy TTM_TT memory type. We reserve that for future porting of GGTT bindings to TTM. Remove the old lmem backend.
