2025-06-03drm/shmem-helper: Import dmabuf without mapping its sg_tableShixiong Ou
[WHY] 1. Drivers using DRM_GEM_SHADOW_PLANE_HELPER_FUNCS and DRM_GEM_SHMEM_DRIVER_OPS (e.g., udl, ast) do not require sg_table import. They only need dma_buf_vmap() to access the shared buffer's kernel virtual address. 2. On certain Aspeed-based boards, a dma_mask of 0xffff_ffff may trigger SWIOTLB during dmabuf import. However, IO_TLB_SEGSIZE restricts the maximum DMA streaming mapping memory, resulting in errors like: ast 0000:07:00.0: swiotlb buffer is full (sz: 3145728 bytes), total 32768 (slots), used 0 (slots) [HOW] Provide a gem_prime_import implementation without sg_table mapping to avoid issues (e.g., "swiotlb buffer is full"). Drivers that do not require sg_table can adopt this.

2025-06-02PCI: j721e: Fix host/endpoint dependenciesArnd Bergmann
The j721e driver has a single platform driver that can be built-in or a loadable module, but it calls two separate backend drivers depending on whether it is a host or endpoint. If the two modes are not the same, we can end up with a situation where the built-in pci-j721e driver tries to call the modular host or endpoint driver, which causes a link failure: ld.lld-21: error: undefined symbol: cdns_pcie_ep_setup >>> referenced by pci-j721e.c >>> drivers/pci/controller/cadence/pci-j721e.o:(j721e_pcie_probe) in archive vmlinux.a ld.lld-21: error: undefined symbol: cdns_pcie_host_setup >>> referenced by pci-j721e.c >>> drivers/pci/controller/cadence/pci-j721e.o:(j721e_pcie_probe) in archive vmlinux.a Rework the dependencies so that the 'select' is done by the common Kconfig symbol, based on which of the two are enabled. Effectively this means that having one built-in makes the other either built-in or disabled, but all configurations will now build.

2025-06-02pwm: axi-pwmgen: fix missing separate external clockDavid Lechner
Add proper support for external clock to the AXI PWM generator driver. In most cases, the HDL for this IP block is compiled with the default ASYNC_CLK_EN=1. With this option, there is a separate external clock that drives the PWM output separate from the peripheral clock. So the driver should be enabling the "axi" clock to power the peripheral and the "ext" clock to drive the PWM output. When ASYNC_CLK_EN=0, the "axi" clock is also used to drive the PWM output and there is no "ext" clock. Previously, if there was a separate external clock, users had to specify only the external clock and (incorrectly) omit the AXI clock in order to get the correct operating frequency for the PWM output. The devicetree bindings are updated to fix this shortcoming and this patch changes the driver to match the new bindings. To preserve compatibility with any existing dtbs that specify only one clock, we don't require the clock name on the first clock.

2025-06-02PCI: WARN (not BUG()) when we fail to assign optional resourcesIlpo Järvinen
Resource fitting/assignment code checks if there's a remainder in add_list (aka. realloc_head in the inner functions) using BUG_ON(). This problem typically results in a mere PCI device resource assignment failure which does not warrant using BUG_ON(). The machine could well come up usable even if this condition occurs because the realloc_head relates to resources which are optional anyway. Change BUG_ON() to WARN_ON_ONCE() and free the list if it's not empty.

This change is essentially a Panfrost port of commit a3707f53eb3f ("drm/panthor: show device-wide list of DRM GEM objects over DebugFS"). The DebugFS file is almost the same as in Panthor, minus the GEM object usage flags, since Panfrost has no kernel-only BO's. Two additional GEM state flags which are displayed but aren't relevant to Panthor are 'Purged' and 'Purgeable', since Panfrost implements an explicit shrinker and a madvise ioctl to flag objects as reclaimable.

Perfcnt samples buffer is not exposed to UM, but we would like to keep a tag on it as a potential debug aid. PRIME imported GEM buffers are UM exposed, but since the usual Panfrost UM driver code path is not followed in their creation, they might remain unlabelled for their entire lifetime, so a generic tag was deemed preferable.

This commit is done in preparation of a following one that will allow UM to set BO labels through a new ioctl().

2025-06-02drm/sched/tests: Use one lock for fence contextPhilipp Stanner
There is no need for separate locks for single jobs and the entire scheduler. The dma_fence context can be protected by the scheduler lock, allowing for removing the jobs' locks. This simplifies things and reduces the likelyhood of deadlocks etc. Replace the jobs' locks with the mock scheduler lock.

2025-06-02drm/i915/guc: Handle race condition where wakeref count drops below 0Jesus Narvaez
There is a rare race condition when preparing for a reset where guc_lrc_desc_unpin() could be in the process of deregistering a context while a different thread is scrubbing outstanding contexts and it alters the context state and does a wakeref put. Then, if there is a failure with deregister_context(), a second wakeref put could occur. As a result the wakeref count could drop below 0 and fail an INTEL_WAKEREF_BUG_ON() check. Therefore if there is a failure with deregister_context(), undo the context state changes and do a wakeref put only if the context was set to be destroyed earlier. v2: Expand comment to better explain change.

The rational is to avoid the need to handle the potential EDEADLK error returned by the former helper, which would require restarting the entire atomic sequence.
