Summary
In the Linux kernel, the following vulnerability has been resolved: clk: qcom: videocc-sm8350: use HW_CTRL_TRIGGER for vcodec GDSCs A recent change in the venus driver results in a stuck clock on the Lenovo ThinkPad X13s, for example, when streaming video in firefox: video_cc_mvs0_clk status stuck at 'off' WARNING: CPU: 6 PID: 2885 at drivers/clk/qcom/clk-branch.c:87 clk_branch_wait+0x144/0x15c ... Call trace: clk_branch_wait+0x144/0x15c clk_branch2_enable+0x30/0x40 clk_core_enable+0xd8/0x29c clk_enable+0x2c/0x4c vcodec_clks_enable.isra.0+0x94/0xd8 [venus_core] coreid_power_v4+0x464/0x628 [venus_core] vdec_start_streaming+0xc4/0x510 [venus_dec] vb2_start_streaming+0x6c/0x180 [videobuf2_common] vb2_core_streamon+0x120/0x1dc [videobuf2_common] vb2_streamon+0x1c/0x6c [videobuf2_v4l2] v4l2_m2m_ioctl_streamon+0x30/0x80 [v4l2_mem2mem] v4l_streamon+0x24/0x30 [videodev] using the out-of-tree sm8350/sc8280xp venus support. [1] Update also the sm8350/sc8280xp GDSC definitions so that the hw control mode can be changed at runtime as the venus driver now requires.
