drm/ast: Fix connector leak during driver unload

2018-12-06T04:12:02+00:00

When unloading the ast driver, a warning message is printed by drm_mode_config_cleanup() because a reference is still held to one of the drm_connector structs. Correct this by calling drm_crtc_force_disable_all() in ast_fbdev_destroy().

drm/ast: Fix incorrect free on ioregs

2018-11-28T23:41:11+00:00

If the platform has no IO space, ioregs is placed next to the already allocated regs. In this case, it should not be separately freed. This prevents a kernel warning from __vunmap "Trying to vfree() nonexistent vm area" when unloading the driver.

drm/ast: Remove existing framebuffers before loading driver

2018-11-18T23:50:02+00:00

If vesafb attaches to the AST device, it configures the framebuffer memory for uncached access by default. When ast.ko later tries to attach itself to the device, it wants to use write-combining on the framebuffer memory, but vesefb's existing configuration for uncached access takes precedence. This results in reduced performance. Removing the framebuffer's configuration before loding the AST driver fixes the problem. Other DRM drivers already contain equivalent code.

drm: drop _mode_ from drm_mode_connector_attach_encoder

Just makes it longer, and for most things in drm_connector.[hc] we just use the drm_connector_ prefix. Done with sed + a bit of manual fixup for the indenting.

drm/ast: fix mode_valid's return type

2018-04-25T07:09:22+00:00

The method struct drm_connector_helper_funcs::mode_valid is defined as returning an 'enum drm_mode_status' but the driver implementation for this method uses an 'int' for it. Fix this by using 'enum drm_mode_status' in the driver too.
