Conversion of instances of printk based drm logging macros to the struct drm_device based logging macros in i915/display/intel_dpll_mgr.c. This also involves extracting the struct drm_i915_private device pointer from various intel types to use in the drm_device based macros. Note that this converts DRM_DEBUG_DRIVER to drm_dbg().

As the coherency of the dma-buf is explicitly defined to be under user control, flushing any caches on attach/detach of the dma-buf is additional work that doesn't aide the user in the slightest.

We have switched from tail manipulation to forced context restore to implement WaIdleLiteRestore. Remove the old defines and comments. Note: we still do emit the WA tail, and use it as our first attempt to avoid forcing a full-restore instead of a lite-restore, we just have a much stronger backup mechanism for repeated preemptions.

Later on, new mapping types were introduced by commit cc662126 ("drm/i915: Introduce DRM_I915_GEM_MMAP_OFFSET"). Those new mapping types suffer from the same lockdep splat issue but they now succeed when tried on top of a userptr object.

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: -

This reverts commit d2a4bb6f. So, turns out that this ended up just breaking things. While many laptops incorrectly advertise themselves as supporting PWM backlight controls, they actually will only work with DPCD backlight controls. Unfortunately, it also seems there are a number of systems which advertise DPCD backlight controls in their eDP DPCD but don't actually support them. Talking with some laptop manufacturers has shown it might be possible to probe this support via the EDID (!?!?) but I haven't been able to confirm that this would work on any other manufacturer's systems. So in the mean time, we'll just revert this commit for now and go back to the old way of doing things. Fixes: d2a4bb6f ("drm/i915: Don't use VBT for detecting DPCD backlight controls") 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:

TGL is suffering of timeouts and fifo underruns when disabling transcoder in MST mode, this is fixed by set TRANS_DDI_MODE_SELECT to 0(HDMI mode) when clearing DDI select. Although BSpec disable sequence don't require this step, it is a harmless change and it is also done by Windows driver. Anyhow HW team was notified about that but it can take some time to documentation to be updated. A case that always lead to those issues is: - do a modeset enabling pipe A and pipe B in the same MST stream leaving A as master - disable pipe A, promote B as master doing a full modeset in A - enable pipe A, changing the master transcoder back to A(doing a full modeset in B) - Pow: underruns and timeouts The transcoders involved will only work again when complete disabled and their power wells turned off causing a reset in their registers. v2: Setting TRANS_DDI_MODE_SELECT to default when clearing DDI select not anymore when disabling TRANS_DDI, both work but this one looks more safe.
