2022-09-12Revert "drm/i915/display: Re-add check for low voltage sku for max dp source ↵Ville Syrjälä1-29/+3
rate" This reverts commit d5929835080a60f9119d024fa42f315913942f76. With the Parade PS8461E MUX workaround (WaEdpLinkRateDataReload) implemented we can get finally rid of the is_low_voltage_sku() check that incorrectly prevents many machines from using the 8.1Gpbs link rate.

2022-09-12drm/i915/vdsc: Set VDSC PIC_HEIGHT before using for DP DSCAnkit Nautiyal3-1/+3

So taking out the lines to set pic_height from the helper intel_dp_dsc_compute_params() to individual encoders, and setting pic_height, before it is used to calculate slice_height for DP.

2022-09-06drm/i915: Implement WaEdpLinkRateDataReloadVille Syrjälä1-0/+22
A lot of modern laptops use the Parade PS8461E MUX for eDP switching. The MUX can operate in jitter cleaning mode or redriver mode, the first one resulting in higher link quality. The jitter cleaning mode needs to know the link rate used and the MUX achieves this by snooping the LINK_BW_SET, LINK_RATE_SELECT and SUPPORTED_LINK_RATES DPCD accesses. When the MUX is powered down (seems this can happen whenever the display is turned off) it loses track of the snooped link rates so when we do the LINK_RATE_SELECT write it no longer knowns which link rate we're selecting, and thus it falls back to the lower quality redriver mode. This results in unstable high link rates (eg. usually 8.1Gbps link rate no longer works correctly). In order to avoid all that let's re-snoop SUPPORTED_LINK_RATES from the sink at the start of every link training. Unfortunately we don't have a way to detect the presence of the MUX. It looks like the set of laptops equipped with this MUX is fairly large and contains devices from multiple manufacturers. It may also still be growing with new models. So a quirk doesn't seem like a very easily maintainable option, thus we shall attempt to do this unconditionally on all machines that use LINK_RATE_SELECT. Hopefully this extra DPCD read doesn't cause issues for any unaffected machine. If that turns out to be the case we'll need to convert this into a quirk in the future.

Bump up the block size appropriately so that we'll copy over the last five bytes of the block as well.

2022-08-29drm/i915/display: avoid warnings when registering dual panel backlightArun R Murthy1-14/+12
Commit 20f85ef89d94 ("drm/i915/backlight: use unique backlight device names") added support for multiple backlight devices on dual panel systems, but did so with error handling on -EEXIST from backlight_device_register(). Unfortunately, that triggered a warning in dmesg all the way down from sysfs_add_file_mode_ns() and sysfs_warn_dup(). Instead of optimistically always attempting to register with the default name ("intel_backlight", which we have to retain for backward compatibility), check if a backlight device with the name exists first, and, if so, use the card and connector based name. v2: reworked on top of the patch commit 20f85ef89d94 ("drm/i915/backlight: use unique backlight device names") v3: fixed the ref count leak(Jani N) Fixes: 20f85ef89d94 ("drm/i915/backlight: use unique backlight device names") Signed-off-by: Arun R Murthy <arun.r.murthy@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220808035750.3111046-1-arun.r.murthy@intel.com (cherry picked from commit 4234ea30051200fc6016de10e4d58369e60b38f1) Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>

git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu Pull iommu updates from Joerg Roedel: - The most intrusive patch is small and changes the default allocation policy for DMA addresses. Before the change the allocator tried its best to find an address in the first 4GB. But that lead to performance problems when that space gets exhaused, and since most devices are capable of 64-bit DMA these days, we changed it to search in the full DMA-mask range from the beginning. This change has the potential to uncover bugs elsewhere, in the kernel or the hardware. There is a Kconfig option and a command line option to restore the old behavior, but none of them is enabled by default. - Add Robin Murphy as reviewer of IOMMU code and maintainer for the dma-iommu and iova code - Chaning IOVA magazine size from 1032 to 1024 bytes to save memory - Some core code cleanups and dead-code removal - Support for ACPI IORT RMR node - Support for multiple PCI domains in the AMD-Vi driver - ARM SMMU changes from Will Deacon: - Add even more Qualcomm device-tree compatible strings - Support dumping of IMP DEF Qualcomm registers on TLB sync timeout - Fix reference count leak on device tree node in Qualcomm driver - Intel VT-d driver updates from Lu Baolu: - Make intel-iommu.h private - Optimize the use of two locks - Extend the driver to support large-scale platforms - Cleanup some dead code - MediaTek IOMMU refactoring and support for TTBR up to 35bit - Basic support for Exynos SysMMU v7 - VirtIO IOMMU driver gets a map/unmap_pages() implementation - Other smaller cleanups and fixes * tag 'iommu-updates-v5.20-or-v6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (116 commits) iommu/amd: Fix compile warning in init code iommu/amd: Add support for AVIC when SNP is enabled iommu/amd: Simplify and Consolidate Virtual APIC (AVIC) Enablement ACPI/IORT: Fix build error implicit-function-declaration drivers: iommu: fix clang -wformat warning iommu/arm-smmu: qcom_iommu: Add of_node_put() when breaking out of loop iommu/arm-smmu-qcom: Add SM6375 SMMU compatible dt-bindings: arm-smmu: Add compatible for Qualcomm SM6375 MAINTAINERS: Add Robin Murphy as IOMMU SUBSYTEM reviewer iommu/amd: Do not support IOMMUv2 APIs when SNP is enabled iommu/amd: Do not support IOMMU_DOMAIN_IDENTITY after SNP is enabled iommu/amd: Set translation valid bit only when IO page tables are in use iommu/amd: Introduce function to check and enable SNP iommu/amd: Globally detect SNP support iommu/amd: Process all IVHDs before enabling IOMMU features iommu/amd: Introduce global variable for storing common EFR and EFR2 iommu/amd: Introduce Support for Extended Feature 2 Register iommu/amd: Change macro for IOMMU control register bit shift to decimal value iommu/exynos: Enable default VM instance on SysMMU v7 iommu/exynos: Add SysMMU v7 register set ...

2022-06-30drm/i915/bios: debug log ddi port info after parsingJani Nikula1-2/+6
The ddc pin and aux channel sanitization may disable DVI/HDMI and DP, respectively, of ports parsed earlier, in "last one wins" fashion. With parsing and printing interleaved, we'll end up logging support first and disabling later anyway. Now that we've split ddi port info parsing and printing, take it further by doing the printing in a separate loop, fixing the logging. Note that this also changes the logging order from VBT child device order to port number order.

Eliminate the PIPECONF RMWs from .comit_commit() so that we can finally declare the whole vblank evade part (and the noarm() part) of the pipe commit free of register reads. Or at least I hope that's the last read... Only the i9xx/ilk codepaths need this for now, but let's add the same thing for hsw+ just in case we want to start calling that during fastsets at some point (eg. to change dithering settings/etc.).

This reverts commit 73867c8709b5 ("drm/i915/display: Remove check for low voltage sku for max dp source rate"), which, on an i7-11850H iGPU with a Thinkpad X1 Extreme Gen 4, attached to a LG LP160UQ1-SPB1 embedded panel, causes wild flickering glitching technicolor pyrotechnics on resumption from suspend. The display shows strobing colors in an utter disaster explosion of pantone, as though bombs were dropped on the leprechauns at the base of the rainbow. Rebooting the machine fixes the issue, presumably because the display is initialized by firmware rather than by i915. Otherwise, the GPU appears to work fine.

Abstract the bit extraction from the VBT per-panel bitfields slightly. Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220615151445.8531-3-ville.syrjala@linux.intel.com Reviewed-by: Jani Nikula <jani.nikula@intel.com>
2022-06-16drm/i915/bios: Don't parse the DPS panel type when the VBT does not have itVille Syrjälä1-0/+8
Older VBTs don't have all the stuff we've defined for the LVDS options block (40). In particular we're currently parsing the DPS panel type bits even though they may not exist, which could mean we end up flagging the machine as supporting static DRRS when the VBT declared no such thing. We don't actually have a clear idea which VBT versions have which bits so we rely on the block size instead. Here's a quick list from my VBT stash: mgm version 108 -> 4 bytes alv version 120 -> 4 bytes cst version 134 -> 14 bytes pnv version 144 -> 14 bytes cl version 142 -> 16 bytes ctg version 155 -> 24 bytes Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220615151445.8531-2-ville.syrjala@linux.intel.com Acked-by: Jani Nikula <jani.nikula@intel.com>
