drivers/gpu/drm/ast: Fix infinite loop if read fails

2016-12-18T13:39:50+00:00

ast_get_dram_info() configures a window in order to access BMC memory.
A BMC register can be configured to disallow this, and if so, causes
an infinite loop in the ast driver which renders the system unusable.

Fix this by erroring out if an error is detected.  On powerpc systems with
EEH, this leads to the device being fenced and the system continuing to
operate.

drm: Make the connector .detect() callback optional

2016-12-01T15:05:53+00:00

Many drivers (21 to be exact) create connectors that are always
connected (for instance to an LVDS or DSI panel). Instead of forcing
them to implement a dummy .detect() handler, make the callback optional
and consider the connector as always connected in that case.

drm/ast: free correct pointer in astfb_create() error paths

2016-11-14T06:45:16+00:00

In the err_free_vram and err_release_fbi error paths in astfb_create(), we
attempt to free afbdev->sysram. The only jumps to these error paths occur
before we assign afbdev->sysram = sysram. Free sysram instead.

drm: define drm_compat_ioctl NULL on CONFIG_COMPAT=n and reduce #ifdefs

2016-11-02T15:33:47+00:00

If we define drm_compat_ioctl NULL on CONFIG_COMPAT=n, we don't have to
check for the config everywhere.

drm/drivers: add support for using the arch wc mapping API.

2016-10-26T06:48:01+00:00

This fixes a regression in all these drivers since the cache
mode tracking was fixed for mixed mappings. It uses the new
arch API to add the VRAM range to the PAT mapping tracking
tables.

drm: use drm_file to tag vm-bos

2016-09-19T09:22:08+00:00

Rather than using "struct file*", use "struct drm_file*" as tag VM tag for
BOs. This will pave the way for "struct drm_file*" without any "struct
file*" back-pointer.
