Adds system power management support in KMS kernel driver. Depends on: https://patchwork.freedesktop.org/series/62377/ Changes since v1: Since we have unified mclk/pclk/pipeline->aclk to one mclk, which will be turned on/off when crtc atomic enable/disable, removed runtime power management. Removes run time get/put related flow. Adds to disable the aclk when register access finished. Changes since v2: Rebases to the drm-misc-next branch. Signed-off-by:

The names for these functions are rather confusing. drm_dp_add_port() sounds like a function that would simply create a port and add it to a topology, and do nothing more. Similarly, drm_dp_update_port() would be assumed to be the function that should be used to update port information after initial creation. While those assumptions are currently correct in how these functions are used, a quick glance at drm_dp_add_port() reveals that drm_dp_add_port() can also update the information on a port, and seems explicitly designed to do so. This can be explained pretty simply by the fact that there's more situations that would involve updating the port information based on a link address response as opposed to a connection status notification than the driver's initial topology probe. Case in point: reprobing link addresses after suspend/resume. Since we're about to start using drm_dp_add_port() differently for suspend/resume reprobing, let's rename both functions to clarify what they actually do.

Extends the user space ioctl for CL submissions so it can include a request to flush the cache once the CL execution has completed. Fixes memory write violation messages reported by the kernel in workloads involving shader memory writes (SSBOs, shader images, scratch, etc) which sometimes also lead to GPU resets during Piglit and CTS workloads. v2: if v3d_job_init() fails we need to kfree() the job instead of v3d_job_put() it (Eric Anholt). v3 (Eric Anholt): - Drop _FLAG suffix from the new flag name. - Add a new param so userspace can tell whether cache flushing is implemented in the kernel.

We say that all of the bits in possible_clones must be set before calling drm_encoder_init(). This isn't true though, since: * The driver may not even have all of the encoder objects that could be used as clones initialized at that point * possible_crtcs isn't used at all outside of userspace, so it's not actually needed to initialize it until drm_dev_register() So, fix it.
