dmabuf internals that nvgpu relies upon for storing meta-data for
compressible buffers changed in k6.1. For now, disable compression
on all k6.1+ kernels.
Additionally, fix numerous compilation issues due to the bit rotted
compression config. All normal Tegra products support compression
and thus have this config enabled. Over the last several years
compression dependent code crept in that wasn't protected under the
compression config.

- During nvgpu module unload, the poweroff sequence
will not wait for the ACK from the PMU for the RPCs sent.
- Due to this, rpc_payload struct info will be present
in pmu seq struct.
- This can lead to memory corruption during unload path.
- To avoid this, return a different value for driver shutting
down scenario from fw ack function and based on this return value
free the RPC payload and release the respective pmu sequence struct.

When a user-domain gets removed, tsg belongs to this also gets removed
and runlist update happens accordingly. If same tsg was submitted to gpu
then updated runlist also needs to re-submit. This works fine with the
existing legacy cases but if GPU is running the shadow domain submitted
by manual mode scheduler and domain belongs to this gets removed then
updated runlist is not being submitted to GPU. This runlist buffer
inconsistency causes mmu fault later.
This change adds a "remove" field in the runlist domain which gets set
to true when runlist update happens for the channel removal. Later
worker thread submit the updated runlist if this flag set to true.

There are three issues with shadow domain submission:
1. runlist mem is not being swapped with mem_hw for shadow domain when
there is non-shadow domain being bound to tsg which does not allow runlist
to have all the tsgs. To fix this nvgpu_runlist_swap_mem() is being called
for shadow domain as well.
2. tsg num_active_channels is being set as part of non-shadow domain which
does happen after shadow domain. Due to this, runlist tsg length is not
being set as part of runlist reconstruct and leaving tsg length 0 for last
tsg. To fix this, tsg num_active_channels always get set for shadow domain
as it gets configured first.
3. NV_BUILD_CONFIGURATION_VARIANT_IS_EMBEDDED is not solving the purpose
to differentiate l4t and embedded_linux builds so using
NV_BUILD_SYSTEM_TYPE in place of this to find out the build type.
L4t is using round robin scheduling and this issue coming with manual mode
scheduling so adding the fix only for manual mode scheduling support.

EPL lib constructor is replaced by NvEplInit() by safety services.
NvGPU, being an EPL user, needs to call NvEplInit before using EPL
API to report errors.
NvEplInit() usage is limited to user space in Linux, so NvGPU is not
expected to call NvEplInit on Linux.

decryption and the decrypted content will be written back
into the same WPR location. So on recovery with LSPMU absence
and on warm boot case, to perform the authentication , the ucode
blob needs to be copied into the WPR from sysmem always.
Below are the LS ucodes authentication type
* LSPMU - Only Signed ( Only for non-safety build, for safety LSPMU is NA)
* CTXSW FECS/GPCCS - Encrypted and Signed (on both safety and non-safety build)

nvpmodel updates the devfreq frequency limits as per power requirements
for specific chip. Clock arbiter ignored these limits and set clock
to maximum supported frequency which may lead to leaking power and
over heating.
Add support to get the devfreq limits by registering PM_QOS notifiers.
Note that with this patch we enable CONFIG_GK20A_PM_QOS when PM_DEVFREQ
is enabled. So it will be enabled for all supported kernels (4.9, 4.14
kernels continue to support this. For 5.10+ kernels notifiers added in
this patch will be used. Thermal framework related notifiers for kernels
after 4.14 will not be registered as those use downstream interfaces
that are not available.)
We maintain devfreq min/max limits in the scale profile and update those
in the notifier calls. We use these limits to clamp the frequency in the
clock arbiter.
