The PM Runtime docs say: Drivers in ->remove() callback should undo the runtime PM changes done in ->probe().

2022-02-23drm/edid: Always set RGB444Maxime Ripard1-1/+1
In order to fill the drm_display_info structure each time an EDID is read, the code currently will call drm_add_display_info with the parsed EDID. drm_add_display_info will then call drm_reset_display_info to reset all the fields to 0, and then set them to the proper value depending on the EDID. In the color_formats case, we will thus report that we don't support any color format, and then fill it back with RGB444 plus the additional formats described in the EDID Feature Support byte. However, since that byte only contains format-related bits since the 1.4 specification, this doesn't happen if the EDID is following an earlier specification. In turn, it means that for one of these EDID, we end up with color_formats set to 0. The EDID 1.3 specification never really specifies what it means by RGB exactly, but since both HDMI and DVI will use RGB444, it's fairly safe to assume it's supposed to be RGB444. Let's move the addition of RGB444 to color_formats earlier in drm_add_display_info() so that it's always set for a digital display.

2022-02-17drm/vc4: crtc: Fix runtime_pm reference countingMaxime Ripard1-3/+5
At boot on the BCM2711, if the HDMI controllers are running, the CRTC driver will disable itself and its associated HDMI controller to work around a hardware bug that would leave some pixels stuck in a FIFO. In order to avoid that issue, we need to run some operations in lockstep between the CRTC and HDMI controller, and we need to make sure the HDMI controller will be powered properly. However, since we haven't enabled it through KMS, the runtime_pm state is off at this point so we need to make sure the device is powered through pm_runtime_resume_and_get, and once the operations are complete, we call pm_runtime_put. However, the HDMI controller will do that itself in its post_crtc_powerdown, which means we'll end up calling pm_runtime_put for a single pm_runtime_get, throwing the reference counting off. Let's remove the pm_runtime_put call in the CRTC code in order to have the proper counting.

2022-02-11drm/cma-helper: Set VM_DONTEXPAND for mmapRobin Murphy1-0/+1
drm_gem_cma_mmap() cannot assume every implementation of dma_mmap_wc() will end up calling remap_pfn_range() (which happens to set the relevant vma flag, among others), so in order to make sure expectations around VM_DONTEXPAND are met, let it explicitly set the flag like most other GEM mmap implementations do. This avoids repeated warnings on a small minority of systems where the display is behind an IOMMU, and has a simple driver which does not override drm_gem_cma_default_funcs. Arm hdlcd is an in-tree affected driver. Out-of-tree, the Apple DCP driver is affected; this fix is required for DCP to be mainlined.

The biggest problem is in rk3288_win23_data[] vs. rk3368_win23_data[] .format field: RK3288's format: VOP_REG(RK3288_WIN2_CTRL0, 0x7, 1) RK3368's format: VOP_REG(RK3368_WIN2_CTRL0, 0x3, 5) Bits 5:6 (i.e., shift 5, mask 0x3) are correct for RK3399, according to the TRM. There are a few other small differences between the 3288 and 3368 definitions that were swapped in commit 7707f7227f09. I reviewed them to the best of my ability according to the RK3399 TRM and fixed them up. This fixes IOMMU issues (and display errors) when testing with BG24 color formats.

2022-01-22lib/stackdepot: allow optional init and stack_table allocation by kvmalloc()Vlastimil Babka4-0/+17
Currently, enabling CONFIG_STACKDEPOT means its stack_table will be allocated from memblock, even if stack depot ends up not actually used. The default size of stack_table is 4MB on 32-bit, 8MB on 64-bit. This is fine for use-cases such as KASAN which is also a config option and has overhead on its own. But it's an issue for functionality that has to be actually enabled on boot (page_owner) or depends on hardware (GPU drivers) and thus the memory might be wasted. This was raised as an issue [1] when attempting to add stackdepot support for SLUB's debug object tracking functionality. It's common to build kernels with CONFIG_SLUB_DEBUG and enable slub_debug on boot only when needed, or create only specific kmem caches with debugging for testing purposes. It would thus be more efficient if stackdepot's table was allocated only when actually going to be used. This patch thus makes the allocation (and whole stack_depot_init() call) optional: - Add a CONFIG_STACKDEPOT_ALWAYS_INIT flag to keep using the current well-defined point of allocation as part of mem_init(). Make CONFIG_KASAN select this flag. - Other users have to call stack_depot_init() as part of their own init when it's determined that stack depot will actually be used. This may depend on both config and runtime conditions. Convert current users which are page_owner and several in the DRM subsystem. Same will be done for SLUB later. - Because the init might now be called after the boot-time memblock allocation has given all memory to the buddy allocator, change stack_depot_init() to allocate stack_table with kvmalloc() when memblock is no longer available. Also handle allocation failure by disabling stackdepot (could have theoretically happened even with memblock allocation previously), and don't unnecessarily align the memblock allocation to its own size anymore.

2022-01-14drm/amdgpu: Fix rejecting Tahiti GPUsLukas Fink1-1/+1
eb4fd29afd4a ("drm/amdgpu: bind to any 0x1002 PCI diplay class device") added generic bindings to amdgpu so that that it binds to all display class devices with VID 0x1002 and then rejects those in amdgpu_pci_probe. Unfortunately it reuses a driver_data value of 0 to detect those new bindings, which is already used to denote CHIP_TAHITI ASICs. The driver_data value given to those new bindings was changed in dd0761fd24ea1 ("drm/amdgpu: set CHIP_IP_DISCOVERY as the asic type by default") to CHIP_IP_DISCOVERY (=36), but it seems that the check in amdgpu_pci_probe was forgotten to be changed. Therefore, it still rejects Tahiti GPUs.

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "It's a relatively calm development cycle, but still lots of updates in the driver side like Intel SOF. Below are some highlights: ALSA / ASoC core: - A new kselftest for ALSA control API - PCM NO_REWINDS support - Potential race fixes around control removals - Unify x86 SG-buffer memory allocation code - Cleanups and race fixes for ASoC DPCM locking ASoC: - Refinements and cleanups around the delay() APIs - Wider use of dev_err_probe(). - Continuing cleanups and improvements to the SOF code - Support for pin switches in simple-card derived cards - Support for AMD Renoir ACP, Asahi Kasei Microdevices AKM4375, Intel systems using NAU8825 and MAX98390, Mediatek MT8915, nVidia Tegra20 S/PDIF, Qualcomm systems using ALC5682I-VS and Texas Instruments TLV320ADC3xxx HD-audio / USB-audio: - Fix deadlock at HD-audio codec unbinding - Fixes for Tegra194 HD-audio, new HDA support for CS35L41 codec - Quirks for Lenovo and HP machines, Gigabyte mobo, Bose device Misc: - Fix virmidi drain behavior Note that the merge of CS35L41 codec support is still half-baked, and at least one ACPI change is missing.
