This patch_context map/unmap pair has become a mere wrapper for the more
general gk20a_mem_{begin,end}(). To be consistent about mappings,
require that each patch_write is surrounded by an explicit begin/end
pair, instead of relying on possible inefficient per-write map/unmap.
Remove also the cpu_va check from .._write_end() since the buffers may
be exist in vidmem without a cpu mapping.

Fix calculation of timeout in multiple places. The #defines
GR_IDLE_CHECK_DEFAULT and GR_IDLE_CHECK_MAX are meant to be used
only for defining the frequency of checking for timeout. Using them
for actual timeouts makes the timeout really short.

Part of golden context initialization is in powerup sequence, and
part done as part of first channel creation. The sequence is
missing a context reset, which causes initialization of golden
context to fail on dGPU.
Just moving the code to golden context initialization does not work,
because iGPU can be rail gated, and part of the sequence is required
in GPU boot.
Thus a part of context initialization is replicated to golden context
init after a context reset.

In gr_gk20a_ctx_zcull_setup(), gr_gk20a_update_smpc_ctxsw_mode(),
and in gk20a_channel_suspend(), we call channel specific APIs
to disable/preempt/enable channel
But we do not consider TSGs in this case
Hence use correct (below) APIs in above functions which
will handle channel or TSG internally :
gk20a_disable_channel_tsg()
gk20a_fifo_preempt()
gk20a_enable_channel_tsg()

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.

In gr_gk20a_find_priv_offset_in_buffer, replace "Unknown address type" error
with informational message: gr_gk20a_exec_ctx_ops calls
gk20a_get_ctx_buffer_offsets and if that fails,
calls gr_gk20a_get_pm_ctx_buffer_offsets; HWPM registers will fail the first
call, so an error or warning is overkill.

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.

pointer would be NULL and crash for nonallocated buffers. This can

Also refactor the function upwards and call it from

The cs_lock cyclestats mutex is unconditionally taken when removing cs
support, but it wouldn't be initialized if some part of gr init would
fail before it. Move it up to happen first, before other inits.

With NVGPU_IOCTL_CHANNEL_EVENTS_CTRL, nvgpu can
raise events to User space. But user space
cannot distinguish between various types of events.
To overcome this, we need finer-grained API to
deliver various events to user space.
Remove old API NVGPU_IOCTL_CHANNEL_EVENTS_CTRL,
and all the support for this API (we can remove
this since User space has not started using this
API at all)
Add new API NVGPU_IOCTL_CHANNEL_EVENT_ID_CTRL
which will accept an event_id (like BPT.INT or
BPT.PAUSE), a command to enable the event,
and return a file descriptor on which
we can raise the event (if cmd=enable)
Event is disabled when file descriptor is closed
Add file operations "gk20a_event_id_ops"
to support polling on event fd
Also add API gk20a_channel_get_event_data_from_id()
to get event_data of event from its id

bug 1648908
This commit adds support for FECS ctxsw tracing. Code is compiled
conditionnaly under CONFIG_GK20_CTXSW_TRACE.
This feature requires an updated FECS ucode that writes one record to a ring
buffer on each context switch. On RM/Kernel side, the GPU driver reads records
from the master ring buffer and generates trace entries into a user-facing
VM ring buffer. For each record in the master ring buffer, RM/Kernel has
to retrieve the vmid+pid of the user process that submitted related work.
Features currently implemented:
- master ring buffer allocation
- debugfs to dump master ring buffer
- FECS record per context switch (with both current and new contexts)
- dedicated device for ctxsw tracing (access to VM ring buffer)
- SOF generation (and access to PTIMER)
- VM ring buffer allocation, and reconfiguration
- enable/disable tracing at user level
- event-based trace filtering
- context_ptr to vmid+pid mapping
- read system call for ctxsw dev
- mmap system call for ctxsw dev (direct access to VM ring buffer)
- poll system call for ctxsw dev
- save/restore register on ELPG/CG6
- separate user ring from FECS ring handling
Features requiring ucode changes:
- enable/disable tracing at FECS level
- actual busy time on engine (bug 1642354)
- master ring buffer threshold interrupt (P1)
- API for GPU to CPU timestamp conversion (P1)
- vmid/pid/uid based filtering (P1)
