drm/radeon: add DisplayPort MST support (v2)

2015-03-19T16:26:51Z

This adds initial DP 1.2 MST support to radeon, on CAYMAN and up in theory. This is off by default. v2: agd5f: - add UNIPHY3 offsets - move atom cmd table code into atombios_encoders.c - whitespace cleanup - replace some magic numbers with proper defines Signed-off-by: Dave Airlie Signed-off-by: Alex Deucher

drm/radeon: program auxch directly (v2)

2015-03-19T16:26:44Z

The atombios tables have an unfortunate restriction on only being able to write 12 bytes, MST really wants 16-bytes here, and since the hw can do it, we should just write directly to it. This uses a module option to allow for it now, and maybe we should provide the old code as a fallback for a while. v2: (agd5f) - move registers to a proper register header - only enable on DCE5+ - enable by default on DCE5+ - Switch pad to aux mode before using it - reformat instance handling to better match the rest of the driver Signed-off-by: Dave Airlie Signed-off-by: Alex Deucher

drm/radeon: make MMU_NOTIFIER optional

2015-01-22T15:42:21Z

In cases where MMU_NOTIFIER is not available, userptr will not be available. Similar to i915, although not making an exception for CAP_SYS_ADMIN. The proposed userspace patches for userptr seem to handle the fall- back properly, so a userptr-less kernel should not be a problem. Signed-off-by: Rob Clark Signed-off-by: Alex Deucher

drm/radeon: split semaphore and sync object handling v2

2014-11-20T18:00:16Z

Previously we just allocated space for four hardware semaphores in each software semaphore object. Make software semaphore objects represent only one hardware semaphore address again by splitting the sync code into it's own object. v2: fix typo in comment Signed-off-by: Christian König Signed-off-by: Alex Deucher

drm/radeon: Add radeon <--> amdkfd interface

2014-07-15T10:53:32Z

This patch adds the interface between the radeon driver and the amdkfd driver. The interface implementation is contained in radeon_kfd.c and radeon_kfd.h. The interface itself is represented by a pointer to struct kfd_dev. The pointer is located inside radeon_device structure. All the register accesses that amdkfd need are done using this interface. This allows us to avoid direct register accesses in amdkfd proper, while also avoiding locking between amdkfd and radeon. The single exception is the doorbells that are used in both of the drivers. However, because they are located in separate pci bar pages, the danger of sharing registers between the drivers is minimal. Having said that, we are planning to move the doorbells as well to radeon. v3: Add interface for sa manager init and fini. The init function will allocate a buffer on system memory and pin it to the GART address space via the radeon sa manager. All mappings of buffers to GART address space are done via the radeon sa manager. The interface of allocate memory will use the radeon sa manager to sub allocate from the single buffer that was allocated during the init function. Change lower_32/upper_32 calls to use linux macros Add documentation for the interface v4: Change ptr field type in kgd_mem from uint32_t* to void* to match to type that is returned by radeon_sa_bo_cpu_addr v5: Change format of mqd structure to work with latest KV firmware Add support for AQL queues creation to enable working with open-source HSA runtime. Move generic kfd-->kgd interface and other generic kgd definitions to a generic header file that will be used by AMD's radeon and amdgpu drivers Signed-off-by: Oded Gabbay

drm/radeon: consolidate r600_audio.c into r600_hdmi.c

2014-10-01T13:00:03Z

Most of that functionality is only used by r600_hdmi.c and I'm planning to change that further. Signed-off-by: Alex Deucher

drm/radeon: move drm_buffer to drm/radeon/

2014-09-10T07:11:21Z

Radeon UMS is the last user of drm_buffer. Move it out of sight so radeon can drop it together with UMS. Signed-off-by: David Herrmann Reviewed-by: Thierry Reding Reviewed-by: Alex Deucher Signed-off-by: Dave Airlie
