Having an array pipe_crc[I915_MAX_PIPES] in struct drm_i915_private should be an obvious clue this should be located in struct intel_crtc instead. Make it so. As a side-effect, fix some errors in indexing pipe_crc with both pipe and crtc index. And, of course, reduce the size of i915_drv.h.

We monitor the health of the system via periodic heartbeat pulses. The pulses also provide the opportunity to perform garbage collection. However, we interpret an incomplete pulse (a missed heartbeat) as an indication that the system is no longer responsive, i.e. hung, and perform an engine or full GPU reset. Given that the preemption granularity can be very coarse on a system, we let the sysadmin override our legacy timeouts which were "optimised" for desktop applications. The heartbeat interval can be adjusted per-engine using, /sys/class/drm/card?/engine/*/heartbeat_interval_ms Signed-off-by:

After initialising a preemption request, we give the current resident a small amount of time to vacate the GPU. The preemption request is for a higher priority context and should be immediate to maintain high quality of service (and avoid priority inversion). However, the preemption granularity of the GPU can be quite coarse and so we need a compromise. The preempt timeout can be adjusted per-engine using, /sys/class/drm/card?/engine/*/preempt_timeout_ms and can be disabled by setting it to 0. Signed-off-by:

When we allow ourselves to sleep before a GPU reset after disabling submission, even for a few milliseconds, gives an innocent context the opportunity to clear the GPU before the reset occurs. However, how long to sleep depends on the typical non-preemptible duration (a similar problem to determining the ideal preempt-reset timeout or even the heartbeat interval). As this seems of a hard policy decision, punt it to userspace. The timeout can be adjusted using /sys/class/drm/card?/engine/*/stop_timeout_ms Signed-off-by:

We busywait on an inflight request (one that is currently executing on HW, and so might complete quickly) prior to setting up an interrupt and sleeping. The trade off is that we keep an expensive CPU core busy in order to avoid wake up latency: where that trade off should lie is best left to the sysadmin. The busywait mechanism can be compiled out with ./scripts/config --set-val DRM_I915_SPIN_REQUEST 0 The maximum busywait duration can be adjusted per-engine using, /sys/class/drm/card?/engine/*/ms_busywait_duration_ns Signed-off-by:

Execlists uses a scheduling quantum (a timeslice) to alternate execution between ready-to-run contexts of equal priority. This ensures that all users (though only if they of equal importance) have the opportunity to run and prevents livelocks where contexts may have implicit ordering due to userspace semaphores. The timeslicing mechanism can be compiled out with ./scripts/config --set-val DRM_I915_TIMESLICE_DURATION 0 The timeslice duration can be adjusted per-engine using, /sys/class/drm/card?/engine/*/timeslice_duration_ms Signed-off-by:

Use the per-engine sysfs directory to let userspace discover the mmio_base of each engine. Prior to recent generations, the user accessible registers on each engine are at a fixed offset relative to each engine -- but require absolute addressing. As the absolute address depends on the actual physical engine, this is not always possible to determine from userspace (for example icl may expose vcs1 or vcs2 as the second vcs engine). Make this easy for userspace to discover by providing the mmio_base in sysfs. Signed-off-by:

Preliminary stub to add engines underneath /sys/class/drm/cardN/, so that we can expose properties on each engine to the sysadmin. To start with we have basic analogues of the i915_query ioctl so that we can pretty print engine discovery from the shell, and flesh out the directory structure. Later we will add writeable sysadmin properties such as per-engine timeout controls.

An odd and highly unlikely path caught us out. On delayed submission (due to an asynchronous reset handler), we poked the priority_hint and kicked the tasklet. However, we had already marked the device as wedged and swapped out the tasklet for a no-op. The result was that we never cleared the priority hint and became upset when we later checked. <0> [574.303565] i915_sel-6278 2.... 481822445us : __i915_subtests: Running intel_execlists_live_selftests/live_error_interrupt <0> [574.303565] i915_sel-6278 2.... 481822472us : __engine_unpark: 0000:00:02.0 rcs0: <0> [574.303565] i915_sel-6278 2.... 481822491us : __gt_unpark: 0000:00:02.0 <0> [574.303565] i915_sel-6278 2.... 481823220us : execlists_context_reset: 0000:00:02.0 rcs0: context:f4ee reset <0> [574.303565] i915_sel-6278 2.... 481824830us : __intel_context_active: 0000:00:02.0 rcs0: context:f51b active <0> [574.303565] i915_sel-6278 2.... 481825258us : __intel_context_do_pin: 0000:00:02.0 rcs0: context:f51b pin ring:{start:00006000, head:0000, tail:0000} <0> [574.303565] i915_sel-6278 2.... 481825311us : __i915_request_commit: 0000:00:02.0 rcs0: fence f51b:2, current 0 <0> [574.303565] i915_sel-6278 2d..1 481825347us : __i915_request_submit: 0000:00:02.0 rcs0: fence f51b:2, current 0 <0> [574.303565] i915_sel-6278 2d..1 481825363us : trace_ports: 0000:00:02.0 rcs0: submit { f51b:2, 0:0 } <0> [574.303565] i915_sel-6278 2.... 481826809us : __intel_context_active: 0000:00:02.0 rcs0: context:f51c active <0> [574.303565] <idle>-0 7d.h2 481827326us : cs_irq_handler: 0000:00:02.0 rcs0: CS error: 1 <0> [574.303565] <idle>-0 7..s1 481827377us : process_csb: 0000:00:02.0 rcs0: cs-irq head=3, tail=4 <0> [574.303565] <idle>-0 7..s1 481827379us : process_csb: 0000:00:02.0 rcs0: csb[4]: status=0x10000001:0x00000000 <0> [574.305593] <idle>-0 7..s1 481827385us : trace_ports: 0000:00:02.0 rcs0: promote { f51b:2*, 0:0 } <0> [574.305611] <idle>-0 7..s1 481828179us : execlists_reset: 0000:00:02.0 rcs0: reset for CS error <0> [574.305611] i915_sel-6278 2.... 481828284us : __intel_context_do_pin: 0000:00:02.0 rcs0: context:f51c pin ring:{start:00007000, head:0000, tail:0000} <0> [574.305611] i915_sel-6278 2.... 481828345us : __i915_request_commit: 0000:00:02.0 rcs0: fence f51c:2, current 0 <0> [574.305611] <idle>-0 7dNs2 481847823us : __i915_request_unsubmit: 0000:00:02.0 rcs0: fence f51b:2, current 1 <0> [574.305611] <idle>-0 7dNs2 481847857us : execlists_hold: 0000:00:02.0 rcs0: fence f51b:2, current 1 on hold <0> [574.305611] <idle>-0 7.Ns1 481847863us : intel_engine_reset: 0000:00:02.0 rcs0: flags=4 <0> [574.305611] <idle>-0 7.Ns1 481847945us : execlists_reset_prepare: 0000:00:02.0 rcs0: depth<-1 <0> [574.305611] <idle>-0 7.Ns1 481847946us : intel_engine_stop_cs: 0000:00:02.0 rcs0: <0> [574.305611] <idle>-0 7.Ns1 538584284us : intel_engine_stop_cs: 0000:00:02.0 rcs0: timed out on STOP_RING -> IDLE <0> [574.305611] <idle>-0 7.Ns1 538584347us : __intel_gt_reset: 0000:00:02.0 engine_mask=1 <0> [574.305611] <idle>-0 7.Ns1 538584406us : execlists_reset_rewind: 0000:00:02.0 rcs0: <0> [574.305611] <idle>-0 7dNs2 538585050us : __i915_request_reset: 0000:00:02.0 rcs0: fence f51b:2, current 1 guilty?

Inside the general i915_oa_init_reg_state() we avoid using the perf->mutex. However, we rely on perf->exclusive_stream being valid to access at that point, and for that we have to control the race with disabling perf. This relies on the disabling being a heavy barrier that inspects all active contexts, after marking the perf->exclusive_stream as not available. This should ensure that there are no more concurrent accesses to the perf->exclusive_stream as we destroy it. Mark up the races around the perf->exclusive_stream so that they stand out much more. (And hopefully we will be running kcsan to start validating that the only races we have are carefully controlled.) Signed-off-by:

We need to be extremely careful inside i915_request_await_start() as it needs to walk the list of requests in the foreign timeline with very little protection. As we hold our own timeline mutex, we can not nest inside the signaler's timeline mutex, so all that remains is our RCU protection. However, to be safe we need to tell the compiler that we may be traversing the list only under RCU protection, and furthermore we need to start declaring requests as elements of the timeline from their construction.

Attaching to the i915_active barrier is a two stage process, and a flush is only effective when the barrier is activation. Thus it is possible for us to see a barrier, and attempt to flush, only for our flush to have no effect.

We don't (yet?) have support for those capabilities, but, given that we shared the pte_encode function betweed GGTT and PPGTT, we still set those bits to the PPGTT PPAT values. The DMA engine gets very confused when those bits are set while the iommu is enabled, leading to errors. E.g. when loading the GuC we get: [ 9.796218] DMAR: DRHD: handling fault status reg 2 [ 9.796235] DMAR: [DMA Write] Request device [00:02.0] PASID ffffffff fault addr 0 [fault reason 02] Present bit in context entry is clear [ 9.899215] [drm:intel_guc_fw_upload [i915]] *ERROR* GuC firmware signature verification failed To fix this, just have dedicated gen8_pte_encode function per type of gtt. Also, explicitly set vm->pte_encode for gen8_ppgtt, even if we don't use it, to make sure we don't accidentally assign it to the GGTT one, like we do for gen6_ppgtt, in case we need it in the future.

Wa_1608008084 is an additional WA that applies to writes on FF_MODE2 register. We can't read it back either from CPU or GPU. Since the other bits should be 0, recommendation to handle Wa_1604555607 is to actually just write the timer value. Do a write only and don't try to read it, neither before or after the WA is applied. Fixes: ff690b21 ("drm/i915/tgl: Implement Wa_1604555607") Signed-off-by:

Looks like the pipe rounding mode bit has moved from PIPE_CHICKEN to PIPE_MISC on tgl. Frob the new location. Bspec does still document the old bits as well, so I left the code for them as is until we get clarification from the hw folks on whether the old bits still do something useful. Signed-off-by:

This register was placed in the middle of the PP_STATUS definition instead of together with the PP_CONTROL where it should. Since it's not used and there are no current plans to use it, just remove the definition. v2: remove the define rather than moving it. Signed-off-by:

The implicit "dev_priv" local variable use has been a long-standing pain point in the register access macros I915_READ(), I915_WRITE(), POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW(). Replace the sole remaining I915_WRITE() in i915_drv.c with intel_uncore_write(), although it might be better to keep the entire file void of direct register access. No functional changes.

The DRAM related routines are pretty isolated from the rest of the i915_drv.c, split it out to a separate file. Put the eDRAM stuff in the same bag, and rename the visible functions to have intel_dram_ prefix. Do some benign whitespace fixes and dev_priv -> i915 conversions while at it. Reviewed-by:

On Tiger Lake we do not support source keying in the pixel formats P010, P012, P016. v2: Move WA to end of function. Create helper function for format check. Less verbose debugging messaging. v3: whitespace v4(MattR): - Actually return EINVAL to reject this combination. - Pass format parameter as u32. - Make test TGL-specific for now. - Switch to per-device logging. - Shorten/simplify comment.
