Use the existence of the workqueue itself to determine when to enable HDCP features rather than sprinkling asic checks all over the code. Also add a check for the existence of the hdcp workqueue in the irq handling on the off chance we get and HPD RX interrupt with the CP bit set. This avoids a crash if the driver doesn't support HDCP for a particular asic.

If we rewind the RING_TAIL on a context, due to a preemption event, we must force the context restore for the RING_TAIL update to be properly handled. Rather than note which preemption events may cause us to rewind the tail, compare the new request's tail with the previously submitted RING_TAIL, as it turns out that timeslicing was causing unexpected rewinds. <idle>-0 0d.s2 1280851190us : __execlists_submission_tasklet: 0000:00:02.0 rcs0: expired last=130:4698, prio=3, hint=3 <idle>-0 0d.s2 1280851192us : __i915_request_unsubmit: 0000:00:02.0 rcs0: fence 66:119966, current 119964 <idle>-0 0d.s2 1280851195us : __i915_request_unsubmit: 0000:00:02.0 rcs0: fence 130:4698, current 4695 <idle>-0 0d.s2 1280851198us : __i915_request_unsubmit: 0000:00:02.0 rcs0: fence 130:4696, current 4695 ^---- Note we unwind 2 requests from the same context <idle>-0 0d.s2 1280851208us : __i915_request_submit: 0000:00:02.0 rcs0: fence 130:4696, current 4695 <idle>-0 0d.s2 1280851213us : __i915_request_submit: 0000:00:02.0 rcs0: fence 134:1508, current 1506 ^---- But to apply the new timeslice, we have to replay the first request before the new client can start -- the unexpected RING_TAIL rewind <idle>-0 0d.s2 1280851219us : trace_ports: 0000:00:02.0 rcs0: submit { 130:4696*, 134:1508 } synmark2-5425 2..s. 1280851239us : process_csb: 0000:00:02.0 rcs0: cs-irq head=5, tail=0 synmark2-5425 2..s. 1280851240us : process_csb: 0000:00:02.0 rcs0: csb[0]: status=0x00008002:0x00000000 ^---- Preemption event for the ELSP update; note the lite-restore synmark2-5425 2..s. 1280851243us : trace_ports: 0000:00:02.0 rcs0: preempted { 130:4698, 66:119966 } synmark2-5425 2..s. 1280851246us : trace_ports: 0000:00:02.0 rcs0: promote { 130:4696*, 134:1508 } synmark2-5425 2.... 1280851462us : __i915_request_commit: 0000:00:02.0 rcs0: fence 130:4700, current 4695 synmark2-5425 2.... 1280852111us : __i915_request_commit: 0000:00:02.0 rcs0: fence 130:4702, current 4695 synmark2-5425 2.Ns1 1280852296us : process_csb: 0000:00:02.0 rcs0: cs-irq head=0, tail=2 synmark2-5425 2.Ns1 1280852297us : process_csb: 0000:00:02.0 rcs0: csb[1]: status=0x00000814:0x00000000 synmark2-5425 2.Ns1 1280852299us : trace_ports: 0000:00:02.0 rcs0: completed { 130:4696!, 134:1508 } synmark2-5425 2.Ns1 1280852301us : process_csb: 0000:00:02.0 rcs0: csb[2]: status=0x00000818:0x00000040 synmark2-5425 2.Ns1 1280852302us : trace_ports: 0000:00:02.0 rcs0: completed { 134:1508, 0:0 } synmark2-5425 2.Ns1 1280852313us : process_csb: process_csb:2336 GEM_BUG_ON(!i915_request_completed(*execlists->active) && !reset_in_progress(execlists)) Fixes: 8ee36e04 ("drm/i915/execlists: Minimalistic timeslicing") Referenecs: 82c69bf5 ("drm/i915/gt: Detect if we miss WaIdleLiteRestore") Signed-off-by: -

Virtual engines are fleeting. They carry a reference count and may be freed when their last request is retired. This makes them unsuitable for the task of housing engine->retire.work so assert that it is not used. Tvrtko tracked down an instance where we did indeed violate this rule. In virtual_submit_request, we flush a completed request directly with __i915_request_submit and this causes us to queue that request on the veng's breadcrumb list and signal it. Leading us down a path where we should not attach the retire. Reported-by:

We lack full state readout of DSC config, which may lead to DSC enable using a config that's all zeros, failing spectacularly. Force full modeset and thus compute config at probe to get a sane state, until we implement DSC state readout. Any fastset that did appear to work with DSC at probe, worked by coincidence. [1] is an example of a change that triggered the issue on TGL DSI DSC.

To enable non-persistent contexts, we require a means of cancelling any inflight work from that context. This is first done "gracefully" by using preemption to kick the active context off the engine, and then forcefully by resetting the engine if it is active. If we are unable to reset the engine to remove hostile userspace, we should not allow userspace to opt into using non-persistent contexts. If the per-engine reset fails, we still do a full GPU reset, but that is rare and usually indicative of much deeper issues. The damage is already done. However, the goal of the interface to allow long running compute jobs without causing collateral damage elsewhere, and if we are unable to support that we should make that known by not providing the interface (and falsely pretending we can).

While certain modeset operations on gv100+ need us to temporarily disable the LUT, we make the mistake of sometimes neglecting to reprogram the LUT after such modesets. In particular, moving a head from one encoder to another seems to trigger this quite often. GV100+ is very picky about having a LUT in most scenarios, so this causes the display engine to hang with the following error code: disp: chid 1 stat 00005080 reason 5 [INVALID_STATE] mthd 0200 data 00000001 code 0000002d) So, fix this by always re-programming the LUT if we're clearing it in a state where the wndw is still visible, and has a XLUT handle programmed.

The input_read function declares the size of the hex array relative to sizeof(buf), but buf is a pointer argument of the function. The hex array is meant to contain hexadecimal representation of the bin array.

If CONFIG_QFMT_V2 is not enabled, but CONFIG_QUOTA is enabled, when a user tries to mount a file system with the quota or project quota enabled, the kernel will emit a very confusing messsage: EXT4-fs warning (device vdc): ext4_enable_quotas:5914: Failed to enable quota tracking (type=0, err=-3). Please run e2fsck to fix. EXT4-fs (vdc): mount failed We will now report an explanatory message indicating which kernel configuration options have to be enabled, to avoid customer/sysadmin confusion.
