* gpu: nvgpu: gv11b: fix fb flush issueseshendra Gadagottu2018-06-25
| | | | | | | | | | | | | | | | | | | | | membar.sys does synchronization with the whole system (GPU and CPU), membar.gl does synchronization within the GPU. In gv11b, fb flush is generating membar.gl instead of membar.sys, which is an issue. To fix this issue. following WAR is used: 1. Use bar1 engine id and bind it to a particular pdb, 2. Then instead of a fb_flush, issue a tlb invalidate of the bar1 pdb. Now allocation of vm for bar1 instance block and bar1 binding is done without check for bar1 support. Only bar1 register mapping is done based on bar1 support enabled.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In gk20a_submit_channel_gpfifo the gpfifo entries can come from a kernel buffer or from userspace. To simplify the logic in gk20a_submit_append_gpfifo, extract out a function that copies the entries directly from userspace to the gpu memory for performance, and another function that copies from a kernel buffer to the gpu memory. The latter is used for kernel submits and when the gpfifo pipe exists which would mean that the gpfifo memory is in vidmem and is thus not directly accessible with a kernel virtual pointer. While this function is being changed a lot, also rename it to start with nvgpu_ instead of gk20a_. Additionally, simplify pushbuffer debug tracing by always using the kernel memory for the prints. Tracing when the gpfifo memory has been allocated in vidmem is no longer supported; sysmem is almost always used in practice anyway.

| | | | | | | | | | | | | | | | | | | | | | | | | | Make ecc sysfs hash table per GPU by adding it as part of nvgpu_os_linux. Using a single hash table might give incorrect results as GPUs have same filenames and a filename is used as a key for a lookup. Add device_attribute as part of struct gk20a_ecc_stat. Using a single array of pointers of device attribute for an ecc_stat results in memory leak and incorrect stats if multiple GPUs are present on the system. This array of pointers will always hold info for GPU which created sysfs nodes last. Fix this by making device attribute array per ecc stat per GPU. Fix ecc stat removal to consider zero sub-units for a given number of hwunits. The multiplication with zero results in not removing any sysfs node at all.
