[PATCH openEuler-22.03-LTS-SP1 V1] drm/radeon: Fix encoder->possible_clones
by Cheng Yu 02 Dec '24

02 Dec '24

From: Ville Syrjälä <ville.syrjala(a)linux.intel.com> stable inclusion from stable-v5.10.228 commit df75c78bfeff99f9b4815c3e79e2b1b1e34fe264 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB2YX3 CVE: CVE-2024-50201 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 28127dba64d8ae1a0b737b973d6d029908599611 upstream. Include the encoder itself in its possible_clones bitmask. In the past nothing validated that drivers were populating possible_clones correctly, but that changed in commit 74d2aacbe840 ("drm: Validate encoder->possible_clones"). Looks like radeon never got the memo and is still not following the rules 100% correctly. This results in some warnings during driver initialization: Bogus possible_clones: [ENCODER:46:TV-46] possible_clones=0x4 (full encoder mask=0x7) WARNING: CPU: 0 PID: 170 at drivers/gpu/drm/drm_mode_config.c:615 drm_mode_config_validate+0x113/0x39c ...

[PATCH OLK-6.6 0/5] virtio-fs: introduce multi-queue support
by Shuai Wu 02 Dec '24

02 Dec '24

Patch1 to patch3 are the interfaces for exporting virtio-fs tags from sysfs during multi-queue modification. patches 4 to 5 add multi-queue support to the virtio-fs driver to enhance performance. Although the multi-queue feature has been in the virtio-fs specification since its inception, the current implementation in the Linux kernel creates multiple queues but enqueues requests to only the first request queue. Shuai Wu (5): virtiofs: export filesystem tags through sysfs virtiofs: emit uevents on filesystem events virtiofs: include a newline in sysfs tag virtio-fs: limit number of request queues virtio-fs: add multi-queue support Documentation/ABI/testing/sysfs-fs-virtiofs | 11 ++ fs/fuse/virtio_fs.c | 200 +++++++++++++++++--- 2 files changed, 181 insertions(+), 30 deletions(-) create mode 100644 Documentation/ABI/testing/sysfs-fs-virtiofs -- 2.33.0
