2024-05-06drm/i915/gt: Automate CCS Mode setting during engine resetsAndi Shyti
We missed setting the CCS mode during resume and engine resets. Create a workaround to be added in the engine's workaround list. This workaround sets the XEHP_CCS_MODE value at every reset. The issue can be reproduced by running: $ clpeak --kernel-latency Without resetting the CCS mode, we encounter a fence timeout: Fence expiration time out i915-0000:03:00.0:clpeak[2387]:2!

https://anongit.freedesktop.org/git/drm/drm-intel into drm-next UAPI Changes: - drm/i915/guc: Use context hints for GT frequency Allow user to provide a low latency context hint. When set, KMD sends a hint to GuC which results in special handling for this context. SLPC will ramp the GT frequency aggressively every time it switches to this context. The down freq threshold will also be lower so GuC will ramp down the GT freq for this context more slowly. We also disable waitboost for this context as that will interfere with the strategy. We need to enable the use of SLPC Compute strategy during init, but it will apply only to contexts that set this bit during context creation. Userland can check whether this feature is supported using a new param- I915_PARAM_HAS_CONTEXT_FREQ_HINT. This flag is true for all guc submission enabled platforms as they use SLPC for frequency management. The Mesa usage model for this flag is here - https://gitlab.freedesktop.org/sushmave/mesa/-/commits/compute_hint - drm/i915/gt: Enable only one CCS for compute workload Enable only one CCS engine by default with all the compute sices allocated to it. While generating the list of UABI engines to be exposed to the user, exclude any additional CCS engines beyond the first instance *** NOTE: This W/A will make all DG2 SKUs appear like single CCS SKUs by default to mitigate a hardware bug. All the EUs will still remain usable, and all the userspace drivers have been confirmed to be able to dynamically detect the change in number of CCS engines and adjust. For the smaller percent of applications that get perf benefit from letting the userspace driver dispatch across all 4 CCS engines we will be introducing a sysfs control as a later patch to choose 4 CCS each with 25% EUs (or 50% if 2 CCS). NOTE: A regression has been reported at https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/10895 However Andi has been triaging the issue and we're closing in a fix to the gap in the W/A implementation: https://lists.freedesktop.org/archives/intel-gfx/2024-April/348747.html Driver Changes: - Add new and fix to existing workarounds: Wa_14018575942 (MTL), Wa_16019325821 (Gen12.70), Wa_14019159160 (MTL), Wa_16015675438, Wa_14020495402 (Gen12.70) (Tejas, John, Lucas) - Fix UAF on destroy against retire race and remove two earlier partial fixes (Janusz) - Limit the reserved VM space to only the platforms that need it (Andi) - Reset queue_priority_hint on parking for execlist platforms (Chris) - Fix gt reset with GuC submission is disabled (Nirmoy) - Correct capture of EIR register on hang (John) - Remove usage of the deprecated ida_simple_xx() API - Refactor confusing __intel_gt_reset() (Nirmoy) - Fix the fix for GuC reset lock confusion (John) - Simplify/extend platform check for Wa_14018913170 (John) - Replace dev_priv with i915 (Andi) - Add and use gt_to_guc() wrapper (Andi) - Remove bogus null check (Rodrigo, Dan) .

2024-04-24drm/i915: Fix gt reset with GuC submission is disabledNirmoy Das
Currently intel_gt_reset() kills the GuC and then resets requested engines. This is problematic because there is a dedicated CSB FIFO which only GuC can access and if that FIFO fills up, the hardware will block on the next context switch until there is space that means the system is effectively hung. If an engine is reset whilst actively executing a context, a CSB entry will be sent to say that the context has gone idle. Thus if reset happens on a very busy system then killing GuC before killing the engines will lead to deadlock because of filled up CSB FIFO. To address this issue, the GuC should be killed only after resetting the requested engines and before calling intel_gt_init_hw(). v2: Improve commit message(John) Cc: John Harrison <john.c.harrison@intel.com> Signed-off-by: Nirmoy Das <nirmoy.das@intel.com> Reviewed-by: John Harrison <John.C.Harrison@Intel.com> Reviewed-by: Andi Shyti <andi.shyti@linux.intel.com> Signed-off-by: Andi Shyti <andi.shyti@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240422201951.633-2-nirmoy.das@intel.com

2024-04-08drm/i915/guc: Fix the fix for reset lock confusionJohn Harrison
The previous fix for the circlular lock splat about the busyness worker wasn't quite complete. Even though the reset-in-progress flag is cleared at the start of intel_uc_reset_finish, the entire function is still inside the reset mutex lock. Not sure why the patch appeared to fix the issue both locally and in CI. However, it is now back again. There is a further complication that the wedge code path within intel_gt_reset() jumps around so much that it results in nested reset_prepare/_finish calls. That is, the call sequence is: intel_gt_reset | reset_prepare | __intel_gt_set_wedged | | reset_prepare | | reset_finish | reset_finish The nested finish means that even if the clear of the in-progress flag was moved to the end of _finish, it would still be clear for the entire second call. Surprisingly, this does not seem to be causing any other problems at present. As an aside, a wedge on fini does not call the finish functions at all. The reset_in_progress flag is left set (twice). So instead of trying to cancel the worker anywhere at all in the reset path, just add a cancel to intel_guc_submission_fini instead. Note that it is not a problem if the worker is still active during a reset. Either it will run before the reset path starts locking things and will simply block the reset code for a tiny amount of time. Or it will run after the locks have been acquired and will early exit due to the try-lock. Also, do not use the reset-in-progress flag to decide whether a synchronous cancel is safe (from a lockdep perspective) or not. Instead, use the actual reset mutex state (both the genuine one and the custom rolled BACKOFF one).

2024-03-28drm/i915/gt: Reset queue_priority_hint on parkingChris Wilson
Originally, with strict in order execution, we could complete execution only when the queue was empty. Preempt-to-busy allows replacement of an active request that may complete before the preemption is processed by HW.

2024-03-26drm/i915/gt: Reset queue_priority_hint on parkingChris Wilson
Originally, with strict in order execution, we could complete execution only when the queue was empty. Preempt-to-busy allows replacement of an active request that may complete before the preemption is processed by HW. If that happens, the request is retired from the queue, but the queue_priority_hint remains set, preventing direct submission until after the next CS interrupt is processed. This preempt-to-busy race can be triggered by the heartbeat, which will also act as the power-management barrier and upon completion allow us to idle the HW. We may process the completion of the heartbeat, and begin parking the engine before the CS event that restores the queue_priority_hint, causing us to fail the assertion that it is MIN. <3>[ 166.210729] __engine_park:283 GEM_BUG_ON(engine->sched_engine->queue_priority_hint != (-((int)(~0U >> 1)) - 1)) <0>[ 166.210781] Dumping ftrace buffer: <0>[ 166.210795] --------------------------------- ... <0>[ 167.302811] drm_fdin-1097 2..s1. 165741070us : trace_ports: 0000:00:02.0 rcs0: promote { ccid:20 1217:2 prio 0 } <0>[ 167.302861] drm_fdin-1097 2d.s2. 165741072us : execlists_submission_tasklet: 0000:00:02.0 rcs0: preempting last=1217:2, prio=0, hint=2147483646 <0>[ 167.302928] drm_fdin-1097 2d.s2. 165741072us : __i915_request_unsubmit: 0000:00:02.0 rcs0: fence 1217:2, current 0 <0>[ 167.302992] drm_fdin-1097 2d.s2. 165741073us : __i915_request_submit: 0000:00:02.0 rcs0: fence 3:4660, current 4659 <0>[ 167.303044] drm_fdin-1097 2d.s1. 165741076us : execlists_submission_tasklet: 0000:00:02.0 rcs0: context:3 schedule-in, ccid:40 <0>[ 167.303095] drm_fdin-1097 2d.s1. 165741077us : trace_ports: 0000:00:02.0 rcs0: submit { ccid:40 3:4660* prio 2147483646 } <0>[ 167.303159] kworker/-89 11..... 165741139us : i915_request_retire.part.0: 0000:00:02.0 rcs0: fence c90:2, current 2 <0>[ 167.303208] kworker/-89 11..... 165741148us : __intel_context_do_unpin: 0000:00:02.0 rcs0: context:c90 unpin <0>[ 167.303272] kworker/-89 11..... 165741159us : i915_request_retire.part.0: 0000:00:02.0 rcs0: fence 1217:2, current 2 <0>[ 167.303321] kworker/-89 11..... 165741166us : __intel_context_do_unpin: 0000:00:02.0 rcs0: context:1217 unpin <0>[ 167.303384] kworker/-89 11..... 165741170us : i915_request_retire.part.0: 0000:00:02.0 rcs0: fence 3:4660, current 4660 <0>[ 167.303434] kworker/-89 11d..1. 165741172us : __intel_context_retire: 0000:00:02.0 rcs0: context:1216 retire runtime: { total:56028ns, avg:56028ns } <0>[ 167.303484] kworker/-89 11..... 165741198us : __engine_park: 0000:00:02.0 rcs0: parked <0>[ 167.303534] <idle>-0 5d.H3. 165741207us : execlists_irq_handler: 0000:00:02.0 rcs0: semaphore yield: 00000040 <0>[ 167.303583] kworker/-89 11..... 165741397us : __intel_context_retire: 0000:00:02.0 rcs0: context:1217 retire runtime: { total:325575ns, avg:0ns } <0>[ 167.303756] kworker/-89 11..... 165741777us : __intel_context_retire: 0000:00:02.0 rcs0: context:c90 retire runtime: { total:0ns, avg:0ns } <0>[ 167.303806] kworker/-89 11..... 165742017us : __engine_park: __engine_park:283 GEM_BUG_ON(engine->sched_engine->queue_priority_hint != (-((int)(~0U >> 1)) - 1)) <0>[ 167.303811] --------------------------------- <4>[ 167.304722] ------------[ cut here ]------------ <2>[ 167.304725] kernel BUG at drivers/gpu/drm/i915/gt/intel_engine_pm.c:283! <4>[ 167.304731] invalid opcode: 0000 [#1] PREEMPT SMP NOPTI <4>[ 167.304734] CPU: 11 PID: 89 Comm: kworker/11:1 Tainted: G W 6.8.0-rc2-CI_DRM_14193-gc655e0fd2804+ #1 <4>[ 167.304736] Hardware name: Intel Corporation Rocket Lake Client Platform/RocketLake S UDIMM 6L RVP, BIOS RKLSFWI1.R00.3173.A03.2204210138 04/21/2022 <4>[ 167.304738] Workqueue: i915-unordered retire_work_handler [i915] <4>[ 167.304839] RIP: 0010:__engine_park+0x3fd/0x680 [i915] <4>[ 167.304937] Code: 00 48 c7 c2 b0 e5 86 a0 48 8d 3d 00 00 00 00 e8 79 48 d4 e0 bf 01 00 00 00 e8 ef 0a d4 e0 31 f6 bf 09 00 00 00 e8 03 49 c0 e0 <0f> 0b 0f 0b be 01 00 00 00 e8 f5 61 fd ff 31 c0 e9 34 fd ff ff 48 <4>[ 167.304940] RSP: 0018:ffffc9000059fce0 EFLAGS: 00010246 <4>[ 167.304942] RAX: 0000000000000200 RBX: 0000000000000000 RCX: 0000000000000006 <4>[ 167.304944] RDX: 0000000000000000 RSI: 0000000000000000 RDI: 0000000000000009 <4>[ 167.304946] RBP: ffff8881330ca1b0 R08: 0000000000000001 R09: 0000000000000001 <4>[ 167.304947] R10: 0000000000000001 R11: 0000000000000001 R12: ffff8881330ca000 <4>[ 167.304948] R13: ffff888110f02aa0 R14: ffff88812d1d0205 R15: ffff88811277d4f0 <4>[ 167.304950] FS: 0000000000000000(0000) GS:ffff88844f780000(0000) knlGS:0000000000000000 <4>[ 167.304952] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 <4>[ 167.304953] CR2: 00007fc362200c40 CR3: 000000013306e003 CR4: 0000000000770ef0 <4>[ 167.304955] PKRU: 55555554 <4>[ 167.304957] Call Trace: <4>[ 167.304958] <TASK> <4>[ 167.305573] ____intel_wakeref_put_last+0x1d/0x80 [i915] <4>[ 167.305685] i915_request_retire.part.0+0x34f/0x600 [i915] <4>[ 167.305800] retire_requests+0x51/0x80 [i915] <4>[ 167.305892] intel_gt_retire_requests_timeout+0x27f/0x700 [i915] <4>[ 167.305985] process_scheduled_works+0x2db/0x530 <4>[ 167.305990] worker_thread+0x18c/0x350 <4>[ 167.305993] kthread+0xfe/0x130 <4>[ 167.305997] ret_from_fork+0x2c/0x50 <4>[ 167.306001] ret_from_fork_asm+0x1b/0x30 <4>[ 167.306004] </TASK> It is necessary for the queue_priority_hint to be lower than the next request submission upon waking up, as we rely on the hint to decide when to kick the tasklet to submit that first request.

2024-03-11drm/i915: Drop WA 16015675438Lucas De Marchi
With dynamic load-balancing disabled on the compute side, there's no reason left to enable WA 16015675438. Drop it from both PVC and DG2. Note that this can be done because now the driver always set a fixed partition of EUs during initialization via the ccs_mode configuration. The flag to GuC is still needed because of 18020744125, so update the comment accordingly.

2024-03-07drm/i915/guc: Use context hints for GT frequencyVinay Belgaumkar
Allow user to provide a low latency context hint. When set, KMD sends a hint to GuC which results in special handling for this context. SLPC will ramp the GT frequency aggressively every time it switches to this context. The down freq threshold will also be lower so GuC will ramp down the GT freq for this context more slowly. We also disable waitboost for this context as that will interfere with the strategy. We need to enable the use of SLPC Compute strategy during init, but it will apply only to contexts that set this bit during context creation. Userland can check whether this feature is supported using a new param- I915_PARAM_HAS_CONTEXT_FREQ_HINT. This flag is true for all guc submission enabled platforms as they use SLPC for frequency management. The Mesa usage model for this flag is here - https://gitlab.freedesktop.org/sushmave/mesa/-/commits/compute_hint v2: Rename flags as per review suggestions (Rodrigo, Tvrtko).

2024-03-04drm/i915/guc: Correct capture of EIR register on hangJohn Harrison
The EIR register (0x20B0) was being included in the engine class list for render and compute as the absolute register address. However, it is actually a ring register available on all engines at an offset of (base) + 0xB0. As it was included as an RCS engine but with the absolute address, GuC was adding on another 0x2000 and coming out at an invalid location. Thus it would reject the register and complain about only managing a partial capture. So update the list to use the RING_EIR version of the register and include it for all engines.
