Disable CRTC/pipes in reverse order because some features (MST in TGL+) requires master and slave relationship between pipes, so it should always pick the lowest pipe as master as it will be enabled first and disable in the reverse order so the master will be the last one to be disabled.

The point of debug_object_activate is to mark the first, and only the first, acquisition. The object then remains active until the last release. However, we marked up all successful first acquires even though we allowed concurrent parties to try and acquire the i915_active simultaneously (serialised by the i915_active.mutex).

The intention is that we first try to pin the current vma into the mappable aperture only if it is already in use or it fits in the free space and will not cause contention. The first attempt was meant to be using PIN_NOEVICT to reuse the current vma if possible, following up with different eviction strategies.

Currently, we don't call dma_set_max_seg_size() for i915 because we intentionally do not limit the segment length that the device supports. However, this results in a warning being emitted if we try to map anything larger than SZ_64K on a kernel with CONFIG_DMA_API_DEBUG_SG enabled: [ 7.751926] DMA-API: i915 0000:00:02.0: mapping sg segment longer than device claims to support [len=98304] [max=65536] [ 7.751934] WARNING: CPU: 5 PID: 474 at kernel/dma/debug.c:1220 debug_dma_map_sg+0x20f/0x340 This was originally brought up on https://bugs.freedesktop.org/show_bug.cgi?id=108517 , and the consensus there was it wasn't really useful to set a limit (and that dma-debug isn't really all that useful for i915 in the first place). Unfortunately though, CONFIG_DMA_API_DEBUG_SG is enabled in the debug configs for various distro kernels. Since a WARN_ON() will disable automatic problem reporting (and cause any CI with said option enabled to start complaining), we really should just fix the problem. Note that as me and Chris Wilson discussed, the other solution for this would be to make DMA-API not make such assumptions when a driver hasn't explicitly set a maximum segment size. But, taking a look at the commit which originally introduced this behavior, commit 78c47830 ("dma-debug: check scatterlist segments"), there is an explicit mention of this assumption and how it applies to devices with no segment size: Conversely, devices which are less limited than the rather conservative defaults, or indeed have no limitations at all (e.g. GPUs with their own internal MMU), should be encouraged to set appropriate dma_parms, as they may get more efficient DMA mapping performance out of it. So unless there's any concerns (I'm open to discussion!), let's just follow suite and call dma_set_max_seg_size() with UINT_MAX as our limit to silence any warnings. Changes since v3: * Drop patch for enabling CONFIG_DMA_API_DEBUG_SG in CI. It looks like just turning it on causes the kernel to spit out bogus WARN_ONs() during some igt tests which would otherwise require teaching igt to disable the various DMA-API debugging options causing this. This is too much work to be worth it, since DMA-API debugging is useless for us. So, we'll just settle with this single patch to squelch WARN_ONs() during driver load for users that have CONFIG_DMA_API_DEBUG_SG turned on for some reason. * Move dma_set_max_seg_size() call into i915_driver_hw_probe() - Chris Wilson Signed-off-by:

vgpu ppgtt notification was split into 2 steps, the first step is to update PVINFO's pdp register and then write PVINFO's g2v_notify register with action code to tirgger ppgtt notification to GVT side. currently these steps were not atomic operations due to no any protection, so it is easy to enter race condition state during the MTBF, stress and IGT test to cause GPU hang. the solution is to add a lock to make vgpu ppgtt notication as atomic operation.

Avoid having to pass around (ctx, engine) everywhere by passing the actual intel_context we intend to use. Today we preach this lesson to igt_gpu_fill_dw and its callers' callers.

In order for the Braswell top-level PD to remain the same from the time of request construction to its submission onto HW, as we may be asynchronously rewriting the page tables (thus changing the expected register state after having already stored the old addresses in the request), the top level PD must be preallocated. So wave goodbye to our lazy allocation of those 4x2 pages. v2: A little bit of write-flushing required (presumably it always has been required, but now we are more susceptible and it is showing up!) v3: Put back the forced-PD-reload on every batch, we can't survive without it and explicitly marking the context for PD reload makes Braswell turn nasty.

When setting up subslice_mask, instead of operating on the slice array directly, use a local variable to start bits per slice, then use this to set the per slice array in one step. Signed-off-by:

Add a new SSEU runtime parameter, eu_stride, which is used to mirror the userspace concept of a range of EUs per subslice. This patch simply adds the parameter and updates usage in the QUERY_TOPOLOGY_INFO handler. v2: Add GEM_BUG_ON to make sure eu_stride is valid Signed-off-by:

HCP/MFX power gating is disabled by default, turn it on for the vd units available. User space will also issue a MI_FORCE_WAKEUP properly to wake up proper subwell. During driver load, init_clock_gating happens after device_info_init_mmio read the vdbox disable fuse register, so only present vd units will have these enabled.

This patch fixes the intel_configure_pps_for_dsc_encoder() function to use cpu_transcoder instead of encoder->type to select the correct DSC registers that was wrongly used in the original patch for one DSC register isntance.

DSC engine on ICL supports only 8 and 10 BPC as the input BPC. But DSC engine in TGL supports 8, 10 and 12 BPC. Add 12 BPC support for DSC while calculating compression configuration. v2: Remove the separate define TGL_DP_DSC_MAX_SUPPORTED_BPC and use the value directly.(More such defines can be removed as part of future patches). (Ville) v3: Use values directly instead of accessing the defines everytime for min and max DSC BPC.

According to PSR2_CTL definition in BSpec there is only one instance of PSR2_CTL. Platforms gen < 12 with EDP transcoder only support PSR2 on TRANSCODER_EDP while on TGL PSR2 is only supported by TRANSCODER_A. Since BDW PSR is allowed on any port, but we need to restrict by transcoder. v8: Renamed _psr2_supported_in_trans() to psr2_supported() (Lucas) v9: Renamed psr2_supported() to transcoder_has_psr2() (Ville) BSpec: 7713 BSpec: 20584 Cc: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Reviewed-by:
