Having I/O regions inside a msm_dp_catalog_private() results in extra layers of one-line wrappers for accessing the data. Move I/O region base and size to the globally visible struct msm_dp_catalog.

2025-07-04drm/msm/dp: split MMSS_DP_DSC_DTO register write to a separate functionDmitry Baryshkov
It's the dp_panel's duty to clear the MMSS_DP_DSC_DTO register. Once DP driver gets DSC support, it will handle that register in other places too.

2025-07-04drm/xe/bmg: fix compressed VRAM handlingMatthew Auld
There looks to be an issue in our compression handling when the BO pages are very fragmented, where we choose to skip the identity map and instead fall back to emitting the PTEs by hand when migrating memory, such that we can hopefully do more work per blit operation. However in such a case we need to ensure the src PTEs are correctly tagged with a compression enabled PAT index on dgpu xe2+, otherwise the copy will simply treat the src memory as uncompressed, leading to corruption if the memory was compressed by the user. To fix this pass along use_comp_pat into emit_pte() on the src side, to indicate that compression should be considered. v2 (Jonathan): tweak the commit message Fixes: 523f191cc0c7 ("drm/xe/xe_migrate: Handle migration logic for xe2+ dgfx") Signed-off-by: Matthew Auld <matthew.auld@intel.com> Cc: Himal Prasad Ghimiray <himal.prasad.ghimiray@intel.com> Cc: Thomas Hellström <thomas.hellstrom@linux.intel.com> Cc: Akshata Jahagirdar <akshata.jahagirdar@intel.com> Cc: <stable@vger.kernel.org> # v6.12+ Reviewed-by: Jonathan Cavitt <jonathan.cavitt@intel.com> Link: https://lore.kernel.org/r/20250701103949.83116-2-matthew.auld@intel.com
2025-07-04bnxt_en: eliminate the compile warning in bnxt_request_irq due to ↵Jason Xing
CONFIG_RFS_ACCEL I received a kernel-test-bot report[1] that shows the [-Wunused-but-set-variable] warning. Since the previous commit I made, as the 'Fixes' tag shows, gives users an option to turn on and off the CONFIG_RFS_ACCEL, the issue then can be discovered and reproduced with GCC specifically. Like Simon and Jakub suggested, use fewer #ifdefs which leads to fewer bugs.

2025-07-04ata: libata-core: Cache the general purpose log directoryDamien Le Moal
The function ata_log_supported() tests if a log page is supported by a device using the General Purpose Log Directory log page, which lists the size of all surported log pages. However, this log page is read from the device using ata_read_log_page() every time ata_log_supported() is called. That is not necessary. Avoid reading the General Purpose Log Directory log page by caching its content in the gp_log_dir buffer defined as part of struct ata_device. The functions ata_read_log_directory() and ata_clear_log_directory() are introduced to manage this buffer. ata_clear_log_directory() zero-fill the gp_log_dir buffer every time ata_dev_configure() is called, that is, when the device is first scanned and when it is being revalidated. The function ata_log_supported() is modified to call ata_read_log_directory() instead of ata_read_log_page(). The function ata_read_log_directory() calls ata_read_log_page() to read the General Purpose Log Directory log page from the device only if the first 16-bits word of the log is not equal to 0x0001, that is, it is not equal to the ACS mandated value for the log version. With this, the log page is read from the device only once for every ata_dev_configure() call. For instance, with pr_debug enabled, a call to ata_dev_configure() before this patch generates the following log page accesses: ata3.00: read log page - log 0x0, page 0x0 ata3.00: read log page - log 0x13, page 0x0 ata3.00: read log page - log 0x0, page 0x0 ata3.00: read log page - log 0x12, page 0x0 ata3.00: read log page - log 0x0, page 0x0 ata3.00: read log page - log 0x30, page 0x0 ata3.00: read log page - log 0x30, page 0x8 ata3.00: read log page - log 0x0, page 0x0 ata3.00: read log page - log 0x0, page 0x0 ata3.00: read log page - log 0x0, page 0x0 ata3.00: read log page - log 0x30, page 0x0 ata3.00: read log page - log 0x0, page 0x0 ata3.00: read log page - log 0x30, page 0x0 ata3.00: read log page - log 0x30, page 0x3 ata3.00: read log page - log 0x30, page 0x4 ata3.00: read log page - log 0x18, page 0x0 That is, the general purpose log directory page is read 7 times. With this patch applied, the number of accesses to this log page is reduced to one: ata3.00: read log page - log 0x0, page 0x0 ata3.00: read log page - log 0x13, page 0x0 ata3.00: read log page - log 0x12, page 0x0 ata3.00: read log page - log 0x30, page 0x0 ata3.00: read log page - log 0x30, page 0x8 ata3.00: read log page - log 0x30, page 0x0 ata3.00: read log page - log 0x30, page 0x0 ata3.00: read log page - log 0x30, page 0x3 ata3.00: read log page - log 0x30, page 0x4 ata3.00: read log page - log 0x18, page 0x0 Signed-off-by: Damien Le Moal <dlemoal@kernel.org> Reviewed-by: Niklas Cassel <cassel@kernel.org> Link: https://lore.kernel.org/r/20250703103622.291272-2-dlemoal@kernel.org Signed-off-by: Niklas Cassel <cassel@kernel.org>
2025-07-04iommu/vt-d: Assign devtlb cache tag on ATS enablementLu Baolu
Commit <4f1492efb495> ("iommu/vt-d: Revert ATS timing change to fix boot failure") placed the enabling of ATS in the probe_finalize callback. This occurs after the default domain attachment, which is when the ATS cache tag is assigned. Consequently, the device TLB cache tag is missed when the domain is attached, leading to the device TLB not being invalidated in the iommu_unmap paths. Fix this by assigning the CACHE_TAG_DEVTLB cache tag when ATS is enabled.

Since this is effectively the correct intent of the code in such cases, mark it as __maybe_unused, tidying up some cruft in the process.
