bfe65407bd gpu: nvgpu: Read sm error ioctl support for tsg
Add READ_SM_ERROR IOCTL support to TSG level.
Moved the struct to save the sm_error details
from gr to tsg as the sm_error support is context
based, not global.

Also corrected MISRA 21.1 error in header file.

nvgpu_dbg_gpu_ioctl_write_single_sm_error_state and
nvgpu_dbg_gpu_ioctl_read_single_sm_error_state
functions are modified to use the tsg struct
nvgpu_tsg_sm_error_state.

52305f0514 gpu: nvgpu: Reduce structure padding waste
The gk20a_init_fifo_setup_sw_common() function allocates memory of
schannel_gk20a and tsg_gk20a tructures for all 512 channels:
    Size   Caller                    Module  Pages     Type
    749568 __nvgpu_vzalloc+0x28/0x78 [nvgpu] pages=182 vmalloc
    602112 __nvgpu_vzalloc+0x28/0x78 [nvgpu] pages=146 vmalloc

This change just simply reorgnizes the member defines in those two
structures to reduce padding waste. After this change:
    Size   Caller                    Module  Pages     Type
    733184 __nvgpu_vzalloc+0x28/0x78 [nvgpu] pages=178 vmalloc
    585728 __nvgpu_vzalloc+0x28/0x78 [nvgpu] pages=142 vmalloc

In summary, it saves 8 pages in 32KB memory.

- Write new pm mode to context buffer header. Ucode use
this mode to enable mode-e context switch. This is Mode-B
context switch of PMs with Mode-E streamout on one context.
If this mode is set, Ucode makes sure that Mode-E pipe
(perfmons, routers, pma) is idle before it context switches PMs.
- This allows us to collect counters in a secure way
(i.e. on context basis) with stream out.

Work around this warning by simply moving the type punning.
This code is certainly dangerous - it assumes the endianness
of the header data is the same as the machine this code is

the warning.

77b806fe7e gpu: nvgpu: gv100: fix PMA list alignment in ctxsw buffer
GV100 ucode is changed so that it expects LIST_nv_perf_pma_ctx_reg list in
ctxsw buffer to be 256 byte aligned but same change is not applied to other
chip ucodes

ADD new HAL (*add_ctxsw_reg_perf_pma) to configure PMA register list and
define a common HAL gr_gk20a_add_ctxsw_reg_perf_pma() for all other
chips except GV100

Define a separate HAL for GV100 gr_gv100_add_ctxsw_reg_perf_pma() and fix
the required alignment in this function

66751bc05d gpu: nvgpu: gv100: fix num_fbpas while adding ctxsw buffer entries
For LIST_nv_pm_fbpa_ctx_regs, we right now call
add_ctxsw_buffer_map_entries_subunits() to add registers corresponding
to all the FBPAs

But while configuring total number of registers, we do not consider
floorswept FBPAs and that causes misalignment in subsequent lists for GV100

Fix this by reading disabled/floorswept FBPAs from fuse and consider only those
FBPAs which are active for GV100

Add new HAL (*add_ctxsw_reg_pm_fbpa) to support this setting and define a
common HAL gr_gk20a_add_ctxsw_reg_pm_fbpa() for all chips except GV100

Define GV100 specific gr_gv100_add_ctxsw_reg_pm_fbpa() with above mentioned
implementation to consider floorsweeping

0ac3ba2a99 gpu: nvgpu: gv11b: fix for gfx preemption
Used chip specific attrib_cb_gfxp_default_size and
attrib_cb_gfxp_size buffer sizes during committing
global callback buffer when gfx preemption is requested.
These sizes are different for gv11b from gp10b.
For gp10b used smaller buffer sizes than specified
value in hw manuals as per sw requirement.

Also used gv11b specific preemption related functions:
gr_gv11b_set_ctxsw_preemption_mode
gr_gv11b_update_ctxsw_preemption_mode

This is required because preemption related buffer
sizes are different for gv11b from gp10b. More optimization
will be done as part of NVGPU-484.

Another issue fixed is: gpu va for preemption buffers
still needs to be 8 bit aligned, even though 49 bits
available now. This done because of legacy implementation
of fecs ucode.

This patch removes the dependency on the header file "uapi/linux/nvgpu.h"
for regops_gk20a.c. The original structure and definitions in the
uapi/linux/nvgpu.h is maintained for userspace libnvrm_gpu.h. The
following changes are made in this patch.

1) Defined common versions of the NVGPU_DBG_GPU_REG_OP* definitions inside
regops_gk20a.h.
2) Defined common version of struct nvgpu_dbg_gpu_reg_op inside
regops_gk20a.h naming it struct nvgpu_dbg_reg_op.
3) Constructed APIs to convert the NVGPU_DBG_GPU_REG_OP* definitions from
linux versions to common and vice versa.
4) Constructed APIs to convert from struct nvgpu_dbg_gpu_reg_op to
struct nvgpu_dbg_reg_op and vice versa.
5) The ioctl handler nvgpu_ioctl_channel_reg_ops first copies from
userspace into a local storage based on struct nvgpu_dbg_gpu_reg_op which
is copied into the struct nvgpu_dbg_reg_op using the APIs above and
after executing the regops handler passes the data back into userspace
by copying back data from struct nvgpu_dbg_reg_op to struct
nvgpu_dbg_gpu_reg_opi.

1480afeb01 gpu: nvgpu: define EVENT_IDs in common code
All the event ids NVGPU_IOCTL_CHANNEL_EVENT_ID_* are defined in linux
specific user header uapi/linux/nvgpu.h and can't be used in common
code

Hence add new definitions of type NVGPU_EVENT_ID_* for all the events
in common code and use them wherever required in common code

For future additions to event ids, we need to update both
NVGPU_IOCTL_CHANNEL_EVENT_ID_* and NVGPU_EVENT_ID_* fields

Also add new API nvgpu_event_id_to_ioctl_channel_event_id() to convert
common event_id of the form NVGPU_EVENT_ID_* to Linux specific event_id
of the form NVGPU_IOCTL_CHANNEL_EVENT_ID_*
Use this API in gk20a_channel/tsg_event_id_post_event() to get correct
event_id

Jira NVGPU-259
