MMU exception conditions are reported in the V3D_MMU_CTRL register as write-1-to-clear (W1C) bits. The MMU interrupt handling code clears any exceptions, but does so by masking out any other bits and writing the result back. There are some important control bits in that register, including MMU_ENABLE, so a safer approach is to simply write back the value just read unaltered. Signed-off-by:

It doesn't seem like drm.h docs are included anywhere. Render them next to drm_mode.h, under the "Userspace API Structures" section. This also allows references to e.g. DRM_CAP_* to be properly linkified elsewhere in our docs. Signed-off-by:

Sphinx doesn't like old doc-comments in drm.h and generates warnings like: ./include/uapi/drm/drm.h:87: warning: cannot understand function prototype: 'struct drm_clip_rect ' ./include/uapi/drm/drm.h:97: warning: cannot understand function prototype: 'struct drm_drawable_info ' ./include/uapi/drm/drm.h:105: warning: cannot understand function prototype: 'struct drm_tex_region ' ... Demote these to regular comments, because converting all of them is quite a lot of work (also requires documenting all of the struct fields for instance). Also many of these structures aren't really used by modern user-space. We can easily convert these remaining old comments to Sphinx style on a one-by-one basis. Signed-off-by: -

The "max-brightness" is a standard backlight property that we need to support for the Samsung GT-I8190 Golden because the display will go black if we crank up the brightness too high. As the platform needs this ability to give picture this is a regression fix along with the addition of the property to the GT-I8190 device tree.

VIRTIO itself has no dependencies and therefore can easily be just select'ed, instead of depending on it. The current depends on causes any others trying to select VIRTIO to fail like this: drivers/gpu/drm/Kconfig:74:error: recursive dependency detected! drivers/gpu/drm/Kconfig:74: symbol DRM_KMS_HELPER is selected by DRM_VIRTIO_GPU drivers/gpu/drm/virtio/Kconfig:2: symbol DRM_VIRTIO_GPU depends on VIRTIO drivers/virtio/Kconfig:2: symbol VIRTIO is selected by GPIO_VIRTIO drivers/gpio/Kconfig:1618: symbol GPIO_VIRTIO depends on GPIOLIB drivers/gpio/Kconfig:14: symbol GPIOLIB is selected by I2C_MUX_LTC4306 drivers/i2c/muxes/Kconfig:47: symbol I2C_MUX_LTC4306 depends on I2C drivers/i2c/Kconfig:8: symbol I2C is selected by FB_DDC drivers/video/fbdev/Kconfig:63: symbol FB_DDC depends on FB drivers/video/fbdev/Kconfig:12: symbol FB is selected by DRM_KMS_FB_HELPER drivers/gpu/drm/Kconfig:80: symbol DRM_KMS_FB_HELPER depends on DRM_KMS_HELPER It seems that having both 'depends on' as well as 'select' on the same symbol sends us into big trouble, and Kconfig can't break up the circular dependency (note that in the tested configuration, neither I2C, FB or DRM are enabled at all). Perhaps we could consider this a bug in Kconfig, but the trouble can easily be circumvented by changing 'depends on' into 'select'. DRM_VIRTIO_GPU also depends on VIRTIO_MENU, so even after this change, that option will only show up if the user already enabled virtio in the config. This change didn't cause any changes in the .config after menuconfig run, so we should be completely safe here. Signed-off-by:

User-space expects to be able to pick a primary plane for each CRTC exposed by the driver. Make sure this assumption holds in drm_mode_config_validate. Use the legacy drm_crtc.primary field to check this, because it's simpler and we require drivers to set it anyways. Accumulate a set of primary planes which are already used for a CRTC in a bitmask. Error out if a primary plane is re-used. v2: new patch v3: - Use u64 instead of __u64 (Jani) - Use `unsigned int` instead of `unsigned` (Jani) v4: - Use u32 instead of u64 for plane mask (Ville) - Use drm_plane_mask instead of BIT (Ville) - Fix typos (Ville) Signed-off-by:
