2025-12-29drm/i915/gvt: Use the appropriate header for the DPLL macroAnkit Nautiyal
The macro `DPLL_ID_SKL_DPLL0` is defined in display/intel_dpll_mgr.h. Previously, GVT included the header display/intel_display_core.h` because other macros also depended on it. After porting those macros to use the new APIs, the only remaining dependency was for the DPLL macro. Replace the indirect include with the correct header and drop intel_display_core.h to reduce unnecessary dependencies.

2025-12-29drm/i915/gvt: Change for_each_pipe to use pipe_valid APIAnkit Nautiyal
Add a new API to check if a given pipe is valid using DISPLAY_RUNTIME_INFO() for GVT. Update GVT to use this API instead of accessing `DISPLAY_RUNTIME_INFO->pipe_mask` directly in the `for_each_pipe` macro. Since `for_each_pipe` is defined in i915/display/intel_display.h, which also contains other macros used by gvt/display.c, we cannot drop the intel_display.h header yet. This causes a build error because `for_each_pipe` is included from both i915/display/intel_display.h and gvt/display_helpers.h. To resolve this, rename the GVT macro to `gvt_for_each_pipe` and make it call the new API. This avoids exposing display internals and prepares for display modularization. v2: - Expose API to check if pipe is valid rather than the runtime info pipe mask. (Jani) - Rename the macro to `gvt_for_each_pipe` to resolve build error. v3: - Use EXPORT_SYMBOL_NS_GPL(..., "I915_GVT"); (Jani) - Use enum pipe at call sites instead of casting in the macro.

2025-12-29drm/i915/gvt: Add header to use display offset functions in macrosAnkit Nautiyal
Introduce gvt/display_helpers.h to make DISPLAY_MMIO_BASE and INTEL_DISPLAY_DEVICE_*_OFFSET macros call exported display functions. This lets GVT keep using existing register macros (e.g., TRANSCONF(display, pipe)) while ensuring offset calculations happen through functions instead of accessing display internals. Ideally, we would remove the display headers that define these macros, but some macros in GVT still depend on them and have not yet been ported. Keeping those headers leads to build conflicts, so as a stopgap, we use temporary ifdef/undef blocks to override the macros with API-backed versions. These will be removed once all dependent macros are ported and the conflicting headers can be safely dropped. Note: TRANSCONF() expects a pipe index but some GVT callers pass a transcoder, causing -Werror=enum-conversion. Fix: cast to enum pipe in the GVT-side macro override. This works for all cases as TRANSCODER_{A,B,C,D} all have 1:1 mapping to PIPE_{A,B,C,D} except for TRANSCODER_EDP which is used in one place. In any case, the cast preserves the previous behaviour. v2: - Remove prefix `gvt/` while including the header file. (Jani) - Explain the rationale behind temporary ifdef/undefs and plan to drop them. (Jani). v3: - Meld the patch to cast argument to enum pipe for the pipe-offset macro. (Jani) - Add a FIXME to highlight the cast.

2025-12-29drm/i915/display: Add APIs to be used by gvt to get the register offsetsAnkit Nautiyal
GVT code uses macros for register offsets that require display internal structures. This makes clean separation of display code and modularization difficult. Introduce APIs to abstract offset calculations: - intel_display_device_pipe_offset() - intel_display_device_trans_offset() - intel_display_device_cursor_offset() - intel_display_device_mmio_base() These APIs return absolute base offsets for the respective register groups, allowing GVT to compute MMIO addresses without using internal macros or struct fields. This prepares the path to separate display-dependent code from i915/gvt/*. v2: - Build GVT APIs only when GVT is actually enabled.

2025-12-29misc: fastrpc: Update dma_bits for CDSP support on Kaanapali SoCKumari Pallavi
DSP currently supports 32-bit IOVA (32-bit PA + 4-bit SID) for both Q6 and user DMA (uDMA) access. This is being upgraded to 34-bit PA + 4-bit SID due to a hardware revision in CDSP for Kaanapali SoC, which expands the DMA addressable range. Update DMA bits configuration in the driver to support CDSP on Kaanapali SoC. Set the default `dma_bits` to 32-bit and update it to 34-bit based on CDSP and OF matching on the fastrpc node.

2025-12-29drm/i915/vdsc: Account for DSC slice overhead in intel_vdsc_min_cdclk()Ankit Nautiyal
When DSC is enabled on a pipe, the pipe pixel rate input to the CDCLK frequency and pipe joining calculation needs an adjustment to account for compression overhead "bubbles" added at each horizontal slice boundary. Account for this overhead while computing min cdclk required for DSC. v2: - Get rid of the scaling factor and return unchanged pixel-rate instead of 0. v3: - Use mul_u32_u32() for the bubble-adjusted pixel rate to avoid 64x64 multiplication and drop redundant casts in DIV_ROUND_UP_ULL().

The restarting message from PF to VF is sent twice during AER error handling: once from adf_error_detected() and again from adf_disable_sriov(). This causes userspace subservices to shutdown unexpectedly when they receive a duplicate restarting message after already being restarted. Avoid calling adf_pf2vf_notify_restarting() and adf_pf2vf_wait_for_restarting_complete() from adf_error_detected() so that the restarting msg is sent only once from PF to VF.

2025-12-28brd: replace simple_strtol with kstrtoul in ramdisk_sizeThorsten Blum
Replace simple_strtol() with the recommended kstrtoul() for parsing the 'ramdisk_size=' boot parameter. Unlike simple_strtol(), which returns a long, kstrtoul() converts the string directly to an unsigned long and avoids implicit casting. Check the return value of kstrtoul() and reject invalid values. This adds error handling while preserving behavior for existing values, and removes use of the deprecated simple_strtol() helper. The current code silently sets 'rd_size = 0' if parsing fails, instead of leaving the default value (CONFIG_BLK_DEV_RAM_SIZE) unchanged.

2025-12-28drm/i915/gem: Zero-initialize the eb.vma array in i915_gem_do_execbufferKrzysztof Niemiec
Initialize the eb.vma array with values of 0 when the eb structure is first set up. In particular, this sets the eb->vma[i].vma pointers to NULL, simplifying cleanup and getting rid of the bug described below. During the execution of eb_lookup_vmas(), the eb->vma array is successively filled up with struct eb_vma objects. This process includes calling eb_add_vma(), which might fail; however, even in the event of failure, eb->vma[i].vma is set for the currently processed buffer. If eb_add_vma() fails, eb_lookup_vmas() returns with an error, which prompts a call to eb_release_vmas() to clean up the mess. Since eb_lookup_vmas() might fail during processing any (possibly not first) buffer, eb_release_vmas() checks whether a buffer's vma is NULL to know at what point did the lookup function fail. In eb_lookup_vmas(), eb->vma[i].vma is set to NULL if either the helper function eb_lookup_vma() or eb_validate_vma() fails. eb->vma[i+1].vma is set to NULL in case i915_gem_object_userptr_submit_init() fails; the current one needs to be cleaned up by eb_release_vmas() at this point, so the next one is set. If eb_add_vma() fails, neither the current nor the next vma is set to NULL, which is a source of a NULL deref bug described in the issue linked in the Closes tag. When entering eb_lookup_vmas(), the vma pointers are set to the slab poison value, instead of NULL. This doesn't matter for the actual lookup, since it gets overwritten anyway, however the eb_release_vmas() function only recognizes NULL as the stopping value, hence the pointers are being set to NULL as they go in case of intermediate failure. This patch changes the approach to filling them all with NULL at the start instead, rather than handling that manually during failure.

2025-12-28ublk: scan partition in async wayMing Lei
Implement async partition scan to avoid IO hang when reading partition tables. Similar to nvme_partition_scan_work(), partition scanning is deferred to a work queue to prevent deadlocks. When partition scan happens synchronously during add_disk(), IO errors can cause the partition scan to wait while holding ub->mutex, which can deadlock with other operations that need the mutex. Changes: - Add partition_scan_work to ublk_device structure - Implement ublk_partition_scan_work() to perform async scan - Always suppress sync partition scan during add_disk() - Schedule async work after add_disk() for trusted daemons - Add flush_work() in ublk_stop_dev() before grabbing ub->mutex Reviewed-by: Caleb Sander Mateos <csander@purestorage.com> Reported-by: Yoav Cohen <yoav@nvidia.com> Closes: https://lore.kernel.org/linux-block/DM4PR12MB63280C5637917C071C2F0D65A9A8A@DM4PR12MB6328.namprd12.prod.outlook.com/ Fixes: 71f28f3136af ("ublk_drv: add io_uring based userspace block driver") Signed-off-by: Ming Lei <ming.lei@redhat.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2025-12-28soc: samsung: exynos-chipid: add google,gs101-otp supportTudor Ambarus
GS101 is different (but also e850 and autov9 I assume) from the SoCs that are currently handled by the exynos-chipid driver because the chip ID info is part of the OTP registers. GS101 OTP has a clock, an interrupt line, a register space (that contains product and chip ID, TMU data, ASV, etc) and a 32Kbit memory space that can be read/program/locked with specific commands. On GS101 the "ChipID block" is just an abstraction, it's not a physical device. When the power-on sequence progresses, the OTP chipid values are loaded to the OTP registers. Add the GS101 chip ID support. The support is intentionally added in the exynos-chipid driver, and not in a dedicated Exynos OTP driver, because we estimate that there will not be any OTP consumers in the kernel other than the chip ID/SoC interface. The downstream GS101 drivers confirm this supposition.
