Always try to stop the rings, even if the GPU reset itself has been disabled (via modparam i915.reset). This should at least stop the hw from spinning in the background consuming resources (e.g. power and memory bandwidth) letting the system rest-in-peace.

Before modifying the ring register (RING_START, HEAD, TAIL, CTL) we first make sure it is stopped (or else the hw may not resample the registers). However, we do not need to let the hw restart until after we have reprogrammed all the rings. This should help prevent situations where pending operations on the ring may resume (because we are trying to re-initialize following an unsuccessful GPU hang, i.e. from i915_gem_unset_wedged).

Since the removal of the stop_machine(), it is allowed and expected for the nop_submit_request() and nop_complete_submit_request() to run in parallel to the i915_gem_set_wedged() processing.

Rather that plumb the link parameters separately to intel_ddi_pre_enable_dp() let's just pass the entire crtc state. intel_ddi_pre_enable_hdmi() already took the crtc state, but for some reason intel_ddi_pre_enable() still wanted to extract has_infoframe from therein and pass it in separately.

Our current logic to read LSPCON's current mode, stops retries and breaks wait-loop, if it gets LSPCON_MODE_INVALID as return from the core function. This doesn't allow us to try reading the mode again. This patch removes this condition and allows retries reading the currnt mode until timeout. This also fixes/prevents some of the noise in form of debug messages while running IGT CI test cases.

A bug recently encountered involved the issue where are we were submitting requests to different ppGTT, each would pin a segment of the GGTT for its logical context and ring. However, this is invisible to eviction as we do not tie the context/ring VMA to a request and so do not automatically wait upon it them (instead they are marked as pinned, preventing eviction entirely). Instead the eviction code must flush those contexts by switching to the kernel context. This selftest tries to fill the GGTT with contexts to exercise a path where the switch-to-kernel-context failed to make forward progress and we fail with ENOSPC. v2: Make the hole in the filled GGTT explicit. v3: Swap out the arbitrary timeout for a private notification from i915_gem_evict_something() Signed-off-by:

For some selftests, we want to issue requests but delay them going to hardware. Furthermore, we don't want those requests to block indefinitely (or else we may hang the driver and block testing) so we want to employ a timeout. So naturally we want a fence that is automatically signaled by a timer. v2: Add kselftests. v3: Limit the API available to selftests; there isn't an overwhelming reason to export it universally.

In the full-ppgtt world, we can fill the GGTT full of context objects. These context objects are currently implicitly tracked by the requests that pin them i.e. they are only unpinned when the request is completed and retired, but we do not have the link from the vma to the request (anymore). In order to unpin those contexts, we have to issue another request and wait upon the switch to the kernel context. The bug during eviction was that we assumed that a full GGTT meant we would have requests on the GGTT timeline, and so we missed situations where those requests where merely in flight (and when even they have not yet been submitted to hw yet). The fix employed here is to change the already-is-idle test to no look at the execution timeline, but count the outstanding requests and then check that we have switched to the kernel context. Erring on the side of overkill here just means that we stall a little longer than may be strictly required, but we only expect to hit this path in extreme corner cases where returning an erroneous error is worse than the delay. v2: Logical inversion when swapping over branches.

Add the minimal amount of PSR tracking into the crtc state. This allows precomputing the possibility of using PSR correctly, and it means we can safely call the psr enable/disable functions for any DP endcoder.

Get rid of redundant intel_dp_num_rates(). We can simply look at the rate and limit based on that. Cc: Manasi Navare <manasi.d.navare@intel.com> Reviewed-by: <manasi.d.navare@intel.com> Signed-off-by:

Turn intel_dp_source_supports_hbr2() into a simple helper to query the pre-filled source rates array, and move the conditions about which platforms support which rates to the single point of truth in intel_dp_set_source_rates(). This also reduces the code paths you have to think about in the source rates initialization in intel_dp_set_source_rates(), making it easier to grasp.

With intel_encoder_current_mode() using the normal state readout code it actually works on PCH platforms as well. So let's nuke the PCH check from intel_lvds_init(). I suppose there aren't any machines that actually need this, but at least we get to eliminate a few lines of code, and one FIXME. Signed-off-by:
