64269c2c55 gpu: nvgpu: modify init_pbdma_intr_descs into separate HALs
init_pbdma_intr_descs HAL ops is used to update the internal values of
the struct intr within struct fifo_gk20a. Three kinds of
intr_descriptors are filled i.e. device_fatal_0, channel_fatal_0 and
restartable_0. Breaking them into separate HALs has the advantage of
reusing the h/w headers corresponding to the device_fatal_0 as they are
same across all the architectures while those of channel_fatal_0 varies.

Another advantage is to now decouple pbdma from filling in values
within the fifo_gk20a struct. A new method gk20a_fifo_init_pbdma_descs
is constructed that initializes the above intr struct by calling the
separate HAL ops for these.

f9ca472d5f gpu: nvgpu: move pbdma HAL functions to hal/fifo/pbdma
The following HAL pointers are moved to a separate HAL unit named pbdma.

pbdma_acquire_val
get_pbdma_signature
dump_pbdma_status
handle_pbdma_intr_0
handle_pbdma_intr_1
read_pbdma_data
reset_pbdma_header

The functions corresponding to these HAL units are also moved to
pbdma_{arch} files under hal/fifo correspondinging to arch gm20b,
gp10b, gv11b and tu104. Any calls to gk20a_readl and gk20a_writel
are replaced by nvgpu_readl and nvgpu_writel respectively.

Moved cbc related code and data from gr to cbc unit.

Ltc and cbc related data is moved from gr header:
1. Ltc related data moved from gr_gk20a -> gk20a and it
will be moved eventually to ltc unit:
u32 slices_per_ltc;
u32 cacheline_size;

2. cbc data moved from gr_gk20a -> nvgpu_cbc
u32 compbit_backing_size;
u32 comptags_per_cacheline;
u32 gobs_per_comptagline_per_slice;
u32 max_comptag_lines;
struct gk20a_comptag_allocator comp_tags;
struct compbit_store_desc compbit_store;

3. Following config data moved gr_gk20a -> gk20a
u32 comptag_mem_deduct;
u32 max_comptag_mem;
These are part of initial config which should be available
during nvgpu_probe. So it can't be moved to nvgpu_cbc.

Modified code to use above updated data structures.

Removed cbc init sequence from gr and added in
common cbc unit. This sequence is getting called
from common nvgpu init code.

cb91bf1e13 gpu: nvgpu: protect recovery with engines_reset_mutex
Rename gr_reset_mutex to engines_reset_mutex and acquire it
before initiating recovery. Recovery running in parallel with
engine reset is not recommended.

On hitting engine reset, h/w drops the ctxsw_status to INVALID in
fifo_engine_status register. Also while the engine is held in reset
h/w passes busy/idle straight through. fifo_engine_status registers
are correct in that there is no context switch outstanding
as the CTXSW is aborted when reset is asserted.

Use deferred_reset_mutex to protect deferred_reset_pending variable
If deferred_reset_pending is true then acquire engines_reset_mutex
and call gk20a_fifo_deferred_reset.
gk20a_fifo_deferred_reset would also check the value of
deferred_reset_pending before initiating reset process

d27f875d2c gpu: nvgpu: change err to info print if failing eng id is -1
For handle_sched_error, change err to info print for failing eng
id returned as -1 i.e. FIFO_INVAL_ENGINE_ID as no engine is found
busy doing ctxsw. May be ctxsw already finished for the context
for which ctxsw timeout intr was triggered.

Possible Causes:
a)
On hitting engine reset, h/w drops the ctxsw_status to INVALID in
fifo_engine_status register. Also while the engine is held in reset
h/w passes busy/idle straight through. fifo_engine_status registers
are correct in that there is no context switch outstanding
as the CTXSW is aborted when reset is asserted.
This is just a side effect of how gv100 and earlier versions of
ctxsw_timeout behave.
With gv10b and later, h/w snaps the context at the point of error
so that s/w can see the tsg_id which caused the HW timeout.
b)
If engines are not busy and ctxsw state is valid then intr occurred
in the past and if the ctxsw state has moved on to VALID from LOAD
or SAVE, it means that whatever timed out eventually finished
anyways. The problem with this is that s/w cannot conclude which
context caused the problem as maybe more switches occurred before
intr is handled.

nvgpu_gr_hwmp_map_find_priv_offset() - find a given offset in the map

The sequence to create the map by reading various netlist segments is
moved to a static API nvgpu_gr_hwpm_map_create()

70453a8606 Revert "Revert "gpu: nvgpu: allocate only active runlists""
This reverts commit f67bc51e51.

Currently a fifo_runlist_info_gk20a structure is allocated and
initialized for each possible runlist. But only a few runlists
are actually used.

Skip allocation and initialization of inactive runlists. Active
runlists info is stored in the active_runlist_info array.If a
runlist is active, then runlist_info[runlist_id] points to one
entry in active_runlist_info. Otherwise, runlist_info[runlist_id]
is NULL.

Operations that used to walk through all runlists are modified
to walk though active runlists only.

c23738969d Revert "Revert "gpu: nvgpu: array of pointers to runlists""
This reverts commit ade1d50cbe.

Currently a fifo_runlist_info_gk20a structure is allocated and
initialized for each possible runlist. But only a few runlists
are actually used.

Use an array of pointers to runlists in fifo_gk20a. The array
keeps existing indexing by runlist_id. In this patch a context
is still allocated for each possible runlist, but follow up
patch will allow to skip context allocation for inactive
runlists.
