| | | | | | | | | | | | | | | | | | | | | bug 1764398 PGSequencer settings use index to writ to PSORDER register setting. HW has implementation for 28 PSORDER (PSORDER0 - 27). Every write will auto increment index and index will wrap around after it reaches 27. In PROD settings we are writing enable for 0 to 27 and zero for 28 to 65. This overwrites enables written to 0 to 27. Effectively those partitions are never power gated.

* gpu: nvgpu: add PRAMIN support for mem accessorsKonsta Holtta2016-05-24
| | | | | | | | | | | | | | | | | | | | To support vidmem, implement a way to access buffers via the PRAMIN window instead of just kernel-mapped sysmem buffers for iGPU as of now. Depending on the buffer aperture, choose between the two access types in the buffer memory accessor functions. vmap()/vunmap() pairs are no-ops for buffers that can't be cpu-mapped. Two uses of DMA_ATTR_READ_ONLY are removed in the ucode loading path to support writing to them too via the indirection in addition to cpu.

* 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: refactor gk20a_mem_{wr,rd} for vidmemKonsta Holtta2016-05-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To support vidmem, pass g and mem_desc to the buffer memory accessor functions. This allows the functions to select the memory access method based on the buffer aperture instead of using the cpu pointer directly (like until now). The selection and aperture support will be in another patch; this patch only refactors these accessors, but keeps the underlying functionality as-is. gk20a_mem_{rd,wr}32() work as previously; add also gk20a_mem_{rd,wr}() for byte-indexed accesses, gk20a_mem_{rd,wr}_n() for memcpy()-like functionality, and gk20a_memset() for filling buffers with a constant. The 8 and 16 bit accessor functions are removed. vmap()/vunmap() pairs are abstracted to gk20a_mem_{begin,end}() to support other types of mappings or conditions where mapping the buffer is unnecessary or different. Several function arguments that would access these buffers are also changed to take a mem_desc instead of a plain cpu pointer. Some relevant occasions are changed to use the accessor functions instead of cpu pointers without them (e.g., memcpying to and from), but the majority of direct accesses will be adjusted later, when the buffers are moved to support vidmem.

* | 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.
