There are several places where we don't want to check
if a particular asic could support DC, but rather, if
DC is enabled. Set a flag if DC is enabled and check
for that rather than if a device supports DC or not.

virtual display is enabled unconditionally in SR-IOV, but
without specifying the virtual_display module, the number
of crtcs defaults to 0. Set a single display by default
for SR-IOV if the virtual_display parameter is not set.
Only enable virtual display by default on SR-IOV on asics
which actually have display hardware.

amdgpu_device_asic_has_dc_support() just checks the asic itself.
amdgpu_device_has_dc_support() is a runtime check which not
only checks the asic, but also other things in the driver
like whether virtual display is enabled. We want the latter
here.

We'll need to get the pixel clock to generate proper display modes for
all the current named modes. Let's add it to struct drm_cmdline_mode and
fill it when parsing the named mode.

The current code to deal with named modes will only set the mode name, and
then it's up to drivers to try to match that name to whatever mode or
configuration they see fit.
The plan is to remove that need and move the named mode handling out of
drivers and into the core, and only rely on modes and properties. Let's
start by properly filling drm_cmdline_mode from a named mode.

The current named mode parsing relies only on the mode name, and doesn't

The current construction of the named mode parsing doesn't allow to extend
it easily. Let's move it to a separate function so we can add more
parameters and modes.
In order for the tests to still pass, some extra checks are needed, so
it's not a 1:1 move.

If we fail to get a valid panel ID in drm_edid_get_panel_id() we'd
like to see the EDID that was read so we have a chance of
understanding what's wrong. There's already a function for that, so
let's call it in the error case.
NOTE: edid_block_read() has a retry loop in it, so actually we'll only
print the block read back from the final attempt. This still seems

- 0 initialize both nvif args and parsed HDMI infoframe buffers
- Fixed missing memset(…, 0, …) for nvif args before sending VSI
infoframe
- Fixed incorrect data pointer and size in nvkm_uoutp_mthd_infoframe()
(was previously pointing at the start of the nvif_outp_infoframe_args

- Get rid of duplicated scdc assignments, since we only use it to write the

struct drm_display_mode embeds a list head, so overwriting
the full struct with another one will corrupt the list
(if the destination mode is on a list). Use drm_mode_copy()
instead which explicitly preserves the list head of
the destination mode.
Even if we know the destination mode is not on any list
using drm_mode_copy() seems decent as it sets a good
example. Bad examples of not using it might eventually
get copied into code where preserving the list head
actually matters.
Obviously one case not covered here is when the mode
itself is embedded in a larger structure and the whole
structure is copied. But if we are careful when copying
into modes embedded in structures I think we can be a
little more reassured that bogus list heads haven't been
propagated in.

This patch adds the support for the notification of HD-audio hotplug
via the already existing drm_audio_component framework to radeon
driver. 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: radeon driver provides the
get_eld ops for HD-audio, and it notifies the audio hotplug via
pin_eld_notify callback upon each radeon_audio_enable() call.
The pin->id is referred as the port number passed to the notifier
callback, and the corresponding connector is looked through the
encoder list in the get_eld callback in turn.
The bind and unbind callbacks handle the device-link so that it
assures the PM call order.
Also, as a gratis bonus, this patch "fixes" the regression by the
recent change in HD-audio to be more strict for the HDMI/DP
connection, too. Since the HD-audio HDMI/DP codec requires both the
connection bit and the valid ELD to be provided, it started failing on
some RADEON gfx boards where the ELD update performed instably. As
this change switches the communication to a direct way between the
audio and the graphics drivers, now the system receives the proper
ELD, and the HDMI/DP hotplug starts working again.
[ v2: fix the logic in radeon_audio_component_get_eld to walk the
connector list since that is where the EDID lives and we can
derive the encoder from the connector because the encoder has
not been assigned at this point (i.e., during monitor probe).
v3: the component binding is moved outside radeon_audio_init() and
_fini(), as those are called from suspend/resume, too.
Drop modeset lock calls that caused Oops.
Moved Kconfig change so that it can be applied on older kernels.
v4: revive drm_modeset_lock*() again, add the missing
device_link_remove() call at unbinding
v5: squash in mutex fix
v6: squash in fix for audio get_eld callback ]

v3d_perfmon_open_file() instantiates a mutex for a particular file
instance, but it never destroys it by calling mutex_destroy() in
v3d_perfmon_close_file().
Similarly, v3d_perfmon_create_ioctl() instantiates a mutex for a
particular perfmon, but it never destroys it by calling mutex_destroy()
in v3d_perfmon_destroy_ioctl().
So, add the missing mutex_destroy on both cases.

mutex_init is supposed to be balanced by a call to mutex_destroy, but
this is not currently happening on the v3d driver.
Considering the introduction of a DRM-managed mutex_init variant, switch
to the drmm_mutex_init.

The same BO may need different MTYPEs and SNOOP flags in PTEs depending
on its current location relative to the mapping GPU. Setting MTYPEs from
clients ahead of time is not practical for coherent memory sharing.
Instead determine the correct MTYPE for the desired coherence model and
current BO location when updating the page tables.
To maintain backwards compatibility with MTYPE-selection in
AMDGPU_VA_OP_MAP, the coherence-model-based MTYPE selection is only
applied if it chooses an MTYPE other than MTYPE_NC (the default).
Add two AMDGPU_GEM_CREATE_... flags to indicate the coherence model. The
default if no flag is specified is non-coherent (i.e. coarse-grained
coherent at dispatch boundaries).
Update amdgpu_amdkfd_gpuvm.c to use this new method to choose the
correct MTYPE depending on the current memory location.
v2:
* check that bo is not NULL (e.g. PRT mappings)
* Fix missing ~ bitmask in gmc_v11_0.c
v3:
* squash in "drm/amdgpu: Inherit coherence flags on dmabuf import"

Currently, we are calling fill_dc_dirty_rects() even if PSR isn't
supported by the relevant link in amdgpu_dm_commit_planes(), this is
undesirable especially because when drm.debug is enabled we are printing
messages in fill_dc_dirty_rects() that are only useful for debugging PSR
(and confusing otherwise). So, we can instead limit the filling of dirty
rectangles to only when PSR is enabled.
