2020-07-31	drm/msm/a6xx: add build_bw_table for A640/A650	Jonathan Marek	1	-0/+74
	This sets up bw tables for A640/A650 similar to A618/A630, 0 DDR bandwidth vote, and the CNOC vote. A640 has the same CNOC addresses as A630 and was working, but this is required for A650 to work. Eventually the bw table should be filled by querying the interconnect driver for each BW in the dts, but use these dummy tables for now.

2020-05-18	drm/msm/a6xx: use msm_gem for GMU memory objects	Jonathan Marek	1	-3/+3
	This gives more fine-grained control over how memory is allocated over the DMA api. In particular, it allows using an address range or pinning to a fixed address.

2018-12-11	drm: msm: Use DRM_DEV_* instead of dev_*	Mamta Shukla	1	-7/+7
	Use DRM_DEV_INFO/ERROR/WARN instead of dev_info/err/debug to generate drm-formatted specific log messages so that it will be easy to differentiate in case of multiple instances of driver. Signed-off-by: Mamta Shukla <mamtashukla555@gmail.com> Signed-off-by: Rob Clark <robdclark@gmail.com>
2018-10-03	drm/msm/a6xx: Poll for HFI responses	Jordan Crouse	1	-106/+55
	The only HFI communication with the GMU on sdm845 happens during initialization and all commands are synchronous. A fancy interrupt tasklet and associated infrastructure is entirely not eeded and puts us at the mercy of the scheduler. Instead poll for the message signal and handle the response immediately and go on our way. Signed-off-by: Jordan Crouse <jcrouse@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
2018-08-10	drm/msm: Add A6XX device support	Jordan Crouse	1	-0/+435
	Add support for the A6XX family of Adreno GPUs. The biggest addition is the GMU (Graphics Management Unit) which takes over most of the power management of the GPU itself but in a ironic twist of fate needs a goodly amount of management itself. Add support for the A6XX core code, the GMU and the HFI (hardware firmware interface) queue that the CPU uses to communicate with the GMU.
