After IGT migrating to dynamic sub-tests, the pipe prefixes in the expected fails list are incorrect. Lets drop those to accurately match the expected fails. In addition, update the xfails list to match the current passing list. This should have ideally failed in the CI run because some tests were marked as fail even though they passed but due to the mismatch in test names, the matching didn't correctly work and was resulting in those failures not being seen. Here is the passing pipeline for apq8016 with this change: https://gitlab.freedesktop.org/drm/msm/-/jobs/57050562Signed-off-by:

This reverts commit 8a91b29f. The regulator_disable() added by the original commit solves one kind of regulator imbalance but adds another one as it allows the regulator to be disabled one more time than it is enabled in the following scenario: 1. Start video pipeline -> sn65dsi83_atomic_pre_enable -> regulator_enable 2. PLL lock fails -> regulator_disable 3. Stop video pipeline -> sn65dsi83_atomic_disable -> regulator_disable The reason is clear from the code flow, which looks like this (after removing unrelated code): static void sn65dsi83_atomic_pre_enable() { regulator_enable(ctx->vcc); if (PLL failed locking) { regulator_disable(ctx->vcc); <---- added by patch being reverted return; } } static void sn65dsi83_atomic_disable() { regulator_disable(ctx->vcc); } The use case for introducing the additional regulator_disable() was removing the module for debugging (see link below for the discussion). If the module is removed after a .atomic_pre_enable, i.e. with an active pipeline from the DRM point of view, .atomic_disable is not called and thus the regulator would not be disabled. According to the discussion however there is no actual use case for removing the module with an active pipeline, except for debugging/development. On the other hand, the occurrence of a PLL lock failure is possible due to any physical reason (e.g. a temporary hardware failure for electrical reasons) so handling it gracefully should be supported. As there is no way for .atomic[_pre]_enable to report an error to the core, the only clean way to support it is calling regulator_disabled() only in .atomic_disable, unconditionally, as it was before.

We must always register the DRM bridge, since zynqmp_dp_hpd_work_func calls drm_bridge_hpd_notify, which in turn expects hpd_mutex to be initialized. We do this before zynqmp_dpsub_drm_init since that calls drm_bridge_attach.

Add the NVreg_RegistryDwords command line parameter, which allows specifying additional registry keys to be sent to GSP-RM. This allows additional configuration, debugging, and experimentation with GSP-RM, which uses these keys to alter its behavior. Note that these keys are passed as-is to GSP-RM, and Nouveau does not parse them. This is in contrast to the Nvidia driver, which may parse some of the keys to configure some functionality in concert with GSP-RM. Therefore, any keys which also require action by the driver may not function correctly when passed by Nouveau. Caveat emptor. The name and format of NVreg_RegistryDwords is the same as used by the Nvidia driver, to maintain compatibility. Signed-off-by:

Avoid usage of global zynqmp_dpsub.dma_enabled flag in DPSUB layer context. This flag signals whether the driver runs in DRM CRTC or DRM bridge mode, assuming that all display layers share the same live or non-live mode of operation. Using per-layer mode instead of global flag will simplify future support of the hybrid scenario. Remove redundant checks in DMA request/release contexts as zynqmp_disp_layer.info is well-defined for all layer types, including the correct number of DMA channels required for each particular layer.

In V3D, the conclusion of a job is indicated by a IRQ. When a job finishes, then we update the local and the global GPU stats of that queue. But, while the GPU stats are being updated, a user might be reading the stats from sysfs or fdinfo. For example, on `gpu_stats_show()`, we could think about a scenario where `v3d->queue[queue].start_ns != 0`, then an interrupt happens, we update the value of `v3d->queue[queue].start_ns` to 0, we come back to `gpu_stats_show()` to calculate `active_runtime` and now, `active_runtime = timestamp`. In this simple example, the user would see a spike in the queue usage, that didn't match reality. In order to address this issue properly, use a seqcount to protect read and write sections of the code. Fixes: 09a93cc4 ("drm/v3d: Implement show_fdinfo() callback for GPU usage stats") Reported-by:

This will make it easier to instantiate the GPU stats variables and it will create a structure where we can store all the variables that refer to GPU stats.

Currently, we manually perform all operations to update the GPU stats variables. Apart from the code repetition, this is very prone to errors, as we can see on commit 35f4f8c9 ("drm/v3d: Don't increment `enabled_ns` twice"). Therefore, create two functions to manage updating all GPU stats variables. Now, the jobs only need to call for `v3d_job_update_stats()` when the job is done and `v3d_job_start_stats()` when starting the job. Co-developed-by:
