a9a7e4f018 gpu: nvgpu: allocate wpr reserve space for NVRISCV pmu
Falcon image is cleanly partitioned between a code and
data section where we don't need extra reserved space.
NVRISCV image has no clear partition for code and data
section, so we need reserved wpr space for runtime use.

4d3a935b1a gpu: nvgpu: enable lazy bootstrap support for NVRISCV pmu
Lazy bootstrap is a secure iGPU feature where LS falcons(FECS and
GPCCS) are bootstrapped by LSPMU in both cold boot and recovery boot.
As there is no ACR running after boot, we need LSPMU to bootstrap LS
falcons to support recovery.
In absence of LSPMU, ACR will bootstrap LS falcons but recovery is
not supported.
This CL will enable Low secure falcon manager(lsfm) to support
Lazy bootstrap feature. This will allow nvgpu to send cmds
to lspmu to bootstrap LS falcons.

c041ad5b4b gpu: nvgpu: split nvgpu power on sequence into 2 stages
1) nvgpu poweron sequence split into two stages:
    - nvgpu_early_init() - Initializes the sub units
      which are required to be initialized before the grgmr init.
      For creating dev node, grmgr init and its dependency unit
      needs to move to early stage of GPU power on.
      After successful nvgpu_early_init() sequence,
      NvGpu can indetify the number of MIG instance required
      for each physical GPU.
    - nvgpu_finalize_poweron() - Initializes the sub units which
      can be initialized at the later stage of GPU power on sequence.

    - grmgr init depends on the following HAL sub units,
      * device - To get the device caps.
      * priv_ring - To get the gpc count and other
        MIG config programming.
      * fb - MIG config programming.
      * ltc - MIG config programming.
      * bios, bus, ecc and clk - dependent module of
        priv_ring/fb/ltc.

2) g->ops.xve.reset_gpu() should be called before GPU sub unit
   initialization. Hence, added g->ops.xve.reset_gpu() HAL in the
   early stage of dGPU power on sequence.

3) Increased xve_reset timeout from 100ms to 200ms.

4) Added nvgpu_assert() for gpc_count, gpc_mask and
   max_veid_count_per_tsg for identify the GPU boot
   device probe failure during nvgpu_init_gr_manager().

After grmgr init, NvGpu can identify the number of MIG
instance required for each physical GPU.
For that, added a new API nvgpu_early_poweron() to handle
early init which is required for before dev node creation.

2) Removed fifo dependency in nvgpu_init_gr_manager()

3) Used get_max_subctx_count() directly to query
the veid/subctx count.

c08719cb0b gpu: nvgpu: move graphics specific HALs to fusa files
All graphics code is under CONFIG_NVGPU_GRAPHICS and all the HALs are
in non-fusa files. In order to support graphics in safety,
CONFIG_NVGPU_GRAPHICS needs to be enabled. But since most of the HALs
are in non-fusa files, this causes huge compilation problem.

Fix this by moving all graphics specific HALs used on gv11b to fusa
files. Graphics specific HALs not used on gv11b remain in non-fusa files
and need not be protected with GRAPHICS config.

Protect call to nvgpu_pmu_save_zbc() also with config
CONFIG_NVGPU_POWER_PG, since it is implemented under that config.

Delete hal/ltc/ltc_gv11b.c since sole function in this file is moved to
fusa file.

Enable nvgpu_writel_loop() in safety build since it is needed for now.
This will be revisited later once requirements are clearer.

Move below CTXSW methods under CONFIG_NVGPU_NON_FUSA for now. Safety
CTXSW ucode does not support these methods. These too will be revisited
later once requirements are clearer.

3ec369d60a gpu: nvgpu: Disable Clock Arbitor for TU104
This patch is to disable the clock arbitor for TU104.
TU104 is not a POR for Drive 6.0 so disabling it to easy migration
of clk arb for GA100.
As a first step all the NVRM Clock tests will be skipped by setting
NVGPU_SUPPORT_CLOCK_CONTROLS to false for TU104.
Then clk arbitor will be rewritten for GA100 and enabled back.
This patch implements by adding a new flag NVGPU_CLK_ARB_ENABLED which
holds the status of clk arbitor for each platform and disables them for
TU104

ff706e5456 gpu: nvgpu: handle ctx_reload when force unbinding the channel
When force closing the channel, NEXT and CTX_RELOAD bits might be set.
Currently CTX_RELOAD bit is ignored. However, due to this, the channel
created after the erroneous unbind encounters FECS fault.

If the channel is unbound while it is running, fifo unbind error
happens and can lead to unspecified behavior.

By moving CTX_RELOAD to other channel in the TSG, the channel can be
unbound safely. In other cases, if the channel is truly running
something when it is being unbound it should either get
preempted or be handled through engine reset.

b91f57d933 gpu: nvgpu: remove assert in devctl processing path
Asserting in the path of devctl processing is not safe here because
incompr_kind can be passed out of range by a malicious app and it will
cause nvgpu-rm to crash. Instead return error in case of out of range
value.
