* gpu: nvgpu: Read all fields of device_infoTerje Bergstrom2016-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | | We were not using the engine_type field in device info, and the code did not handle chained entries properly. The code assumed that first entry is for graphics and second for CE, which is not always true. Improve the code to go through all entries of device_info, and preserve values across entries until we reach the last entry. Only last entry triggers a write to fifo engine info. There can also be multiple engines with same type, so accumulate interrupts and reset ids from all of them. As the code got fixed, now it reads the engine enum correctly from hardware. We used to compare that against CE0, but we should compare against CE2. gk20a_fifo_reset_engine() uses wrong constants - it is passed a internal numbering of engines, but it compares them against hardware engine enum.

* gpu: nvgpu: improve channel interleave supportAingara Paramakuru2016-03-15
| | | | | | | | | | | | | | | | | | | | | | | | | | Previously, only "high" priority bare channels were interleaved between all other bare channels and TSGs. This patch decouples priority from interleaving and introduces 3 levels for interleaving a bare channel or TSG: high, medium, and low. The levels define the number of times a channel or TSG will appear on a runlist (see nvgpu.h for details). By default, all bare channels and TSGs are set to interleave level low. Userspace can then request the interleave level to be increased via the CHANNEL_SET_RUNLIST_INTERLEAVE ioctl (TSG-specific ioctl will be added later). As timeslice settings will soon be coming from userspace, the default timeslice for "high" priority channels has been restored.

| | | | | | | | | | | | | | At zcull bind we disable whole GR engine. This is unnecessary, so instead disable only the channel and make sure it's unloaded. Introduces also an API in fifo_gk20a.c to do the channel disable. gr_gk20a_ctx_zcull_setup() was always passed true as last parameter, so remove parameter.
