2023-06-15drm/msm/dpu: add DSC 1.2 hw blocks for relevant chipsetsAbhinav Kumar
Add DSC 1.2 hardware blocks to the catalog with necessary sub-block and feature flag information. Each display compression engine (DCE) contains dual DSC encoders so both share same base address but with its own different sub block address. changes in v4: -- delete DPU_DSC_HW_REV_1_1 -- re arrange sc8280xp_dsc[] changes in v4: -- fix checkpatch warning changes in v10: -- remove hard slice from commit text -- replace DPU_DSC_NATIVE_422_EN with DPU_DSC_NATIVE_42x_EN -- change DSC_BLK_1_2 .len from 0x100 to 0x29c changes in v11: -- remove comment at DSC_BLK_1_2 marco Signed-off-by: Abhinav Kumar <quic_abhinavk@quicinc.com> Signed-off-by: Kuogee Hsieh <quic_khsieh@quicinc.com> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Reviewed-by: Marijn Suijten <marijn.suijten@somainline.org> Patchwork: https://patchwork.freedesktop.org/patch/539507/ Link: https://lore.kernel.org/r/1685036458-22683-10-git-send-email-quic_khsieh@quicinc.com Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>
2023-06-15drm/msm/dpu: add support for DSC encoder v1.2 engineKuogee Hsieh
Add support for DSC 1.2 by providing the necessary hooks to program the DPU DSC 1.2 encoder.

2023-06-15drm/msm/dsi: update hdisplay calculation for dsi_timing_setupJessica Zhang
Currently, hdisplay is being divided by 3 for DSC. However, this calculation only works for cases where BPP = 8.

2023-06-13Revert "drm/amdgpu: remove TOPDOWN flags when allocating VRAM in large bar ↵Arunpravin Paneer Selvam
system" This reverts commit c105518679b6e87232874ffc989ec403bee59664. This patch disables the TOPDOWN flag for APU and few dGPU cards which has the VRAM size equal to the BAR size. When we enable the TOPDOWN flag, we get the free blocks at the highest available memory region and we don't split the lower order blocks. This change is required to keep off the fragmentation related issues particularly in ASIC which has VRAM space <= 500MiB Hence, we are reverting this patch.

2023-06-13drm/amdgpu: Reset CP_VMID_PREEMPT after trailing fence signaledJiadong Zhu
When MEC executes unmap_queue for mid command buffer preemption, it will kick the write pointer of the gfx ring, set CP_VMID_PREEMPT to trigger the preemption and wait for CP_VMID_PREEMPT becomes zero after the preemption done. There is a race condition that PFP may excute the resetting command before MEC set CP_VMID_PREEMPT. As a result, hang happens as CP_VMID_PREEMPT is always 0xffff. To avoid this, we send resetting CP_VMID_PREEMPT command after the trailing fence is siganled and update gfx write pointer explicitly.

2023-06-13drm/nouveau: don't detect DSM for non-NVIDIA deviceRatchanan Srirattanamet
The call site of nouveau_dsm_pci_probe() uses single set of output variables for all invocations. So, we must not write anything to them unless it's an NVIDIA device. Otherwise, if we are called with another device after the NVIDIA device, we'll clober the result of the NVIDIA device. For example, if the other device doesn't have _PR3 resources, the detection later would miss the presence of power resource support, and the rest of the code will keep using Optimus DSM, breaking power management for that machine. Also, because we're detecting NVIDIA's DSM, it doesn't make sense to run this detection on a non-NVIDIA device anyway. Thus, check at the beginning of the detection code if this is an NVIDIA card, and just return if it isn't. This, together with commit d22915d22ded ("drm/nouveau/devinit/tu102-: wait for GFW_BOOT_PROGRESS == COMPLETED") developed independently and landed earlier, fixes runtime power management of the NVIDIA card in Lenovo Legion 5-15ARH05. Without this patch, the GPU resumption code will "timeout", sometimes hanging userspace. As a bonus, we'll also stop preventing _PR3 usage from the bridge for unrelated devices, which is always nice, I guess.

2023-06-10drm/i915: add a dedicated workqueue inside drm_i915_privateLuca Coelho
In order to avoid flush_scheduled_work() usage, add a dedicated workqueue in the drm_i915_private structure. In this way, we don't need to use the system queue anymore. This change is mostly mechanical and based on Tetsuo's original patch[1]. v6 by Jani: - Also create unordered_wq for mock device Link: https://patchwork.freedesktop.org/series/114608/ [1] Cc: Tetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Cc: Jani Nikula <jani.nikula@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Jani Nikula <jani.nikula@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/c816ebe17ef08d363981942a096a586a7658a65e.1686231190.git.jani.nikula@intel.com
2023-06-10drm/i915: use pointer to i915 instead of rpm in wakerefLuca Coelho
Currently a pointer to an intel_runtime_pm structure is stored in the wake reference structures so the runtime data can be accessed. We can save the entire device information (drm_i915_private) instead, since we'll need to reference the new workqueue we'll add in subsequent patches.

2023-06-09mm/gup: remove unused vmas parameter from get_user_pages()Lorenzo Stoakes
Patch series "remove the vmas parameter from GUP APIs", v6. (pin_/get)_user_pages[_remote]() each provide an optional output parameter for an array of VMA objects associated with each page in the input range. These provide the means for VMAs to be returned, as long as mm->mmap_lock is never released during the GUP operation (i.e. the internal flag FOLL_UNLOCKABLE is not specified). In addition, these VMAs can only be accessed with the mmap_lock held and become invalidated the moment it is released. The vast majority of invocations do not use this functionality and of those that do, all but one case retrieve a single VMA to perform checks upon. It is not egregious in the single VMA cases to simply replace the operation with a vma_lookup(). In these cases we duplicate the (fast) lookup on a slow path already under the mmap_lock, abstracted to a new get_user_page_vma_remote() inline helper function which also performs error checking and reference count maintenance. The special case is io_uring, where io_pin_pages() specifically needs to assert that the VMAs underlying the range do not result in broken long-term GUP file-backed mappings. As GUP now internally asserts that FOLL_LONGTERM mappings are not file-backed in a broken fashion (i.e. requiring dirty tracking) - as implemented in "mm/gup: disallow FOLL_LONGTERM GUP-nonfast writing to file-backed mappings" - this logic is no longer required and so we can simply remove it altogether from io_uring. Eliminating the vmas parameter eliminates an entire class of danging pointer errors that might have occured should the lock have been incorrectly released. In addition, the API is simplified and now clearly expresses what it is intended for - applying the specified GUP flags and (if pinning) returning pinned pages. This change additionally opens the door to further potential improvements in GUP and the possible marrying of disparate code paths. I have run this series against gup_test with no issues. Thanks to Matthew Wilcox for suggesting this refactoring! This patch (of 6): No invocation of get_user_pages() use the vmas parameter, so remove it. The GUP API is confusing and caveated. Recent changes have done much to improve that, however there is more we can do. Exporting vmas is a prime target as the caller has to be extremely careful to preclude their use after the mmap_lock has expired or otherwise be left with dangling pointers. Removing the vmas parameter focuses the GUP functions upon their primary purpose - pinning (and outputting) pages as well as performing the actions implied by the input flags. This is part of a patch series aiming to remove the vmas parameter altogether.
