2024-04-12iommu/amd: Do not enable SNP when V2 page table is enabledVasant Hegde
DTE[Mode]=0 is not supported when SNP is enabled in the host. That means to support SNP, IOMMU must be configured with V1 page table (See IOMMU spec [1] for the details). If user passes kernel command line to configure IOMMU domains with v2 page table (amd_iommu=pgtbl_v2) then disable SNP as the user asked by not forcing the page table to v1.

2024-04-11drm/i915: Add SIZE_HINTS property for cursorsVille Syrjälä
Advertize more suitable cursor sizes via the new SIZE_HINTS plane property. We can't really enumerate all supported cursor sizes on the platforms where the cursor height can vary freely, so for simplicity we'll just expose all square+POT sizes between each platform's min and max cursor limits. Depending on the platform this will give us one of three results: - 64x64,128x128,256x256,512x512 - 64x64,128x128,256x256 - 64x64 Cc: Simon Ser <contact@emersion.fr> Cc: Jonas Ådahl <jadahl@redhat.com> Cc: Daniel Stone <daniel@fooishbar.org> Cc: Sameer Lattannavar <sameer.lattannavar@intel.com> Cc: Sebastian Wick <sebastian.wick@redhat.com> Cc: Harry Wentland <harry.wentland@amd.com> Cc: Pekka Paalanen <pekka.paalanen@collabora.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240318204408.9687-3-ville.syrjala@linux.intel.com Reviewed-by: Juha-Pekka Heikkila <juhapekka.heikkila@gmail.com>
2024-04-11drm: Introduce plane SIZE_HINTS propertyVille Syrjälä
Add a new immutable plane property by which a plane can advertise a handful of recommended plane sizes. This would be mostly exposed by cursor planes as a slightly more capable replacement for the DRM_CAP_CURSOR_WIDTH/HEIGHT caps, which can only declare a one size fits all limit for the whole device. Currently eg. amdgpu/i915/nouveau just advertize the max cursor size via the cursor size caps. But always using the max sized cursor can waste a surprising amount of power, so a better strategy is desirable. Most other drivers don't specify any cursor size at all, in which case the ioctl code just claims that 64x64 is a great choice. Whether that is actually true is debatable. A poll of various compositor developers informs us that blindly probing with setcursor/atomic ioctl to determine suitable cursor sizes is not acceptable, thus the introduction of the new property to supplant the cursor size caps. The compositor will now be free to select a more optimal cursor size from the short list of options. Note that the reported sizes (either via the property or the caps) make no claims about things such as plane scaling. So these things should only really be consulted for simple "cursor like" use cases.

2024-04-11binder: check offset alignment in binder_get_object()Carlos Llamas
Commit 6d98eb95b450 ("binder: avoid potential data leakage when copying txn") introduced changes to how binder objects are copied. In doing so, it unintentionally removed an offset alignment check done through calls to binder_alloc_copy_from_buffer() -> check_buffer(). These calls were replaced in binder_get_object() with copy_from_user(), so now an explicit offset alignment check is needed here. This avoids later complications when unwinding the objects gets harder. It is worth noting this check existed prior to commit 7a67a39320df ("binder: add function to copy binder object from buffer"), likely removed due to redundancy at the time.

2024-04-11comedi: vmk80xx: fix incomplete endpoint checkingNikita Zhandarovich
While vmk80xx does have endpoint checking implemented, some things can fall through the cracks. Depending on the hardware model, URBs can have either bulk or interrupt type, and current version of vmk80xx_find_usb_endpoints() function does not take that fully into account. While this warning does not seem to be too harmful, at the very least it will crash systems with 'panic_on_warn' set on them. Fix the issue found by Syzkaller [1] by somewhat simplifying the endpoint checking process with usb_find_common_endpoints() and ensuring that only expected endpoint types are present. This patch has not been tested on real hardware.
