Implmented functions to load and execute PUB which
is the safety POR.
PUB has following functionality:
1) Lower PLM
2) Reset PMU
3) FBPA register access to devtools

Secure Boot and Runtime (SBR) microcode comprises of
single PLM Update Binary (PUB) which will execute on
SEC2 Engine Falcon. NVGPU shall load and execute PUB
and wait for falcon halt. On successful halt NVGPU
shall proceed with ns ucode loading on respective
falcons.

Current clk unit has multiple header files under include folder.
This has combination of public struct which is accessed outside the

This patch segregates them based on their accessibility.
All private items are moved into ucode_clk_inf.h from include which only
clk can access.
All public items are moved into include/clk.h which other units can
access and removed the clk_xxx.h files

Currently, size of zbc index table is defined as a macro. This macro is

Adding below hal will update zbc index table size as per number of

ZBC index table address 0 is reserved. Logic to start zbc table index
from 1 is moved to corresponding hals.

*Init the clk domains inside pmu.clk unit.
*Set this in a member variable and send it to hal.clk unit
*Use this to determine the valid clock domains and read the
 monitor registers for each valid domains.
*Return the domain with error code.
*With this all the clk domain data is removed from hal.clk and

1c991a58af gpu: nvgpu: Add SM diversity support
To achieve permanent fault coverage, the CTAs launched by
each kernel in the mission and redundant contexts must execute on
different hardware resources. This feature proposes modifications
in the software to modify the virtual SM id to TPC mapping across
the mission and redundant contexts. The virtual SM identifier to TPC
mapping is done by nvgpu when setting up the patch context.

The recommendation for the redundant setting is to offset the
assignment by one TPC, and not by one GPC. This will ensure that both
GPC and TPC diversity. The SM and Quadrant diversity will happen
naturally. For kernels with few CTAs, the diversity is guaranteed
to be 100%. In case of completely random CTA allocation,
e.g. large number of CTAs in the waiting queue, the diversity is
1 - 1/#SM, or 87.5% for GV11B, 97.9% for TU104.

Added NvGpu CFLAGS to enable/disable the SM diversity support
"CONFIG_NVGPU_SM_DIVERSITY".

This support is only enabled on gv11b and tu104 QNX non safety build.

fba516ffae gpu: nvgpu: enable PMU ECC interrupt early
PMU IRQs were not enabled assuming entire functionality for LS PMU.
Debugging early init issues of PMU falcon ECC errors triggered
during nvgpu power-on will be cumbersome if interrupts are not
enabled early. FMEA analysis of the nvgpu init path also
requires this interrupt be enabled earlier.

Hence, Enable the PMU ECC IRQ early during nvgpu_finalize_poweron.
pmu_enable_irq is updated to enable interrupts differently for
safety and non-safety. PMU interrupts disabling is moved out
of nvgpu_pmu_destroy to nvgpu_prepare_poweroff. Prepared new
wrapper API nvgpu_pmu_enable_irq.

PMU ECC init and isr mutex init is moved to the beginning of
nvgpu_pmu_early_init as for safety, ls pmu code path is
disabled. Fixed the pmu_early_init dependent and mc
interrupt related unit tests.

Update the doxygen for changed functions.

a52ee77837 gpu: nvgpu: Add SM diversity gpu characteristic flag
To achieve permanent fault coverage, the CTAs launched by
each kernel in the mission and redundant contexts must execute
on different hardware resources.
This feature requires a change in software to make it possible
to modify the virtual SM id to TPC mapping across mission and
redundant contexts.

This CL adds only SM diversity flags which are exposed to
its clients through ioctl/devctl interfaces.
Actual virtual SM id to TPC mapping implementation
will be part of upcoming patch sets.

Added NvGpu CFLAGS to identify the safety build
"CONFIG_NVGPU_BUILD_CONFIGURATION_IS_SAFETY"

a8c9c800cd gpu: nvgpu: reorganization of MC interrupts control
Previously, unit interrupt enabling/disabling and corresponding MC level
interrupt enabling/disabling was not done at the same time.
With this change, stall and nonstall interrupt for units are programmed
at MC level along with individual unit interrupts. Kept access to MC
interrupt registers through mc.intr_lock spinlock.

For doing this separated CE and GR interrupt mask functions.
mc.intr_enable is only used when there is global interrupt
control to be set. Removed mc_gp10b.c as mc_gp10b_intr_enable
is now removed. Removed following functions - mc_gv100_intr_enable,
mc_gv11b_intr_enable & intr_tu104_enable. Removed intr_pmu_unit_config
as we can use the generic unit interrupt control function.
