[PATCH] drm/msm/dp: reset drm_dev to NULL at dp_display_unbind()
by Kuogee Hsieh 22 Jun '22

22 Jun '22

During msm initialize phase, dp_display_unbind() will be called to undo initializations had been done by dp_display_bind() previously if there is error happen at msm_drm_bind. Under this kind of circumstance, drm_device may not be populated completed which causes system crash at drm_dev_dbg(). This patch reset drm_dev to NULL so that following drm_dev_dbg() will not refer to any internal fields of drm_device to prevent system from crashing.

[PATCH v2 00/68] drm/vc4: Fix hotplug for vc4
by Maxime Ripard 22 Jun '22

22 Jun '22

Hi, Here is a series that address multiple issues when trying to unbind/rebind vc4-related devices to their drivers. Most of these issues involve either use-after-free, improper resource liberation or similar. It has been tested on the Pi3 and Pi4, with X and glxgears running and KASAN enabled to properly validate our memory accesses. Pi3 isn't functional after a rebind though, with vblank timeouts occuring. I'm not quite sure why at this point, but at least the kernel doesn't completely … [View More]crash now.

[PATCH] drm/fourcc: fix integer type usage in uapi header
by Carlos Llamas 22 Jun '22

22 Jun '22

Kernel uapi headers are supposed to use __[us]{8,16,32,64} types defined by <linux/types.h> as opposed to 'uint32_t' and similar. See [1] for the relevant discussion about this topic. In this particular case, the usage of 'uint64_t' escaped headers_check as these macros are not being called here. However, the following program triggers a compilation error: #include <drm/drm_fourcc.h> int main() { unsigned long x = AMD_FMT_MOD_CLEAR(RB); return 0; } gcc error: drm.… [View More]

[PATCH v4 0/7] usb: typec: Introduce typec-switch binding
by Prashant Malani 22 Jun '22

22 Jun '22

This series introduces a binding for Type-C data lane switches. These control the routing and operating modes of USB Type-C data lanes based on the PD messaging from the Type-C port driver regarding connected peripherals. The first patch introduces a change to the Type-C mux class mode-switch matching code, while the second adds a config guard to a Type-C header. The next couple of patches introduce the new "typec-switch" binding as well as one user of it (the ANX7625 drm bridge). The … [View More]

[PATCH] drm/msm/dpu: Increment vsync_cnt before waking up userspace
by Stephen Boyd 22 Jun '22

22 Jun '22

The 'vsync_cnt' is used to count the number of frames for a crtc. Unfortunately, we increment the count after waking up userspace via dpu_crtc_vblank_callback() calling drm_crtc_handle_vblank(). drm_crtc_handle_vblank() wakes up userspace processes that have called drm_wait_vblank_ioctl(), and if that ioctl is expecting the count to increase it won't. Increment the count before calling into the drm APIs so that we don't have to worry about ordering the increment with anything else in drm. This … [View More]
