This info is missing from the implementation of PIO channels as they're

4 years agodrm/nouveau: Add HD-audio component notifier support

drm/nouveau: Add HD-audio component notifier support

This patch adds the support for the notification of HD-audio hotplug
via the already existing drm_audio_component framework.  This allows
us more reliable hotplug notification and ELD transfer without
accessing HD-audio bus; it's more efficient, and more importantly, it
works without waking up the runtime PM.

The implementation is rather simplistic: nouveau driver provides the
get_eld ops for HD-audio, and it notifies the audio hotplug via
pin_eld_notify callback upon each nv50_audio_enable() and _disable()
call.  As the HD-audio pin assignment seems corresponding to the CRTC,
the crtc->index number is passed directly as the zero-based port
number.

The bind and unbind callbacks handle the device-link so that it
assures the PM call order.

drm/nouveau/acr: implement new subdev to replace "secure boot"

ACR is responsible for managing the firmware for LS (Low Secure) falcons,
this was previously handled in the driver by SECBOOT.

This rewrite started from some test code that attempted to replicate the
procedure RM uses in order to debug early Turing ACR firmwares that were
provided by NVIDIA for development.

Compared with SECBOOT, the code is structured into more individual steps,
with the aim of making the process easier to follow/debug, whilst making
it possible to support newer firmware versions that may have a different
binary format or API interface.

The HS (High Secure) binary(s) are now booted earlier in device init, to
match the behaviour of RM, whereas SECBOOT would delay this until we try
to boot the first LS falcon.

There's also additional debugging features available, with the intention
of making it easier to solve issues during FW/HW bring-up in the future.

drm/nouveau/mmu: Add correct turing page kinds

Turing introduced a new simplified page kind
scheme, reducing the number of possible page
kinds from 256 to 16.  It also is the first
NVIDIA GPU in which the highest possible page
kind value is not reserved as an "invalid" page
kind.

To address this, the invalid page kind is made
an explicit property of the MMU HAL, and a new
table of page kinds is added to the tu102 MMU
HAL.

One hardware change not addressed here is that
0x00 is technically no longer a supported page
kind, and pitch surfaces are instead intended to
share the block-linear generic page kind 0x06.
However, because that will be a rather invasive
change to nouveau and 0x00 still works fine in
practice on Turing hardware, addressing this new
behavior is deferred.

The pointer used to walk the table of move ops

declared static, meaning its state was carried
over between invocations of the function, and also

Since the table is ordered such that newer GPU

that initializing newer GPUs after older GPUs
would result in no suitable ttm move acceleration
operations being found, and ttm would fall back
to CPU blits on the older GPUs.

drm/nouveau/kms/nv04-nv4x: Use match_string() helper to simplify the code

match_string() returns the array index of a matching string.
Use it instead of the open-coded implementation.

4 years agodrm/nouveau/ce/gp10b: Use correct copy engine

drm/nouveau/ce/gp10b: Use correct copy engine

gp10b uses the new engine enumeration mechanism introduced in the Pascal
architecture. As a result, the copy engine, which used to be at index 2
for prior Tegra GPU instantiations, has now moved to index 0. Fix up the
index and also use the gp100 variant of the copy engine class because on
gp10b the PASCAL_DMA_COPY_B class is not supported.

drm/nouveau/ltc/gp10b: Add custom L2 cache implementation

There are extra registers that need to be programmed to make the level 2
cache work on GP10B, such as the stream ID register that is used when an
SMMU is used to translate memory addresses.
