eafc9c2704 amdgpu: use NULL instead of 0 for pointer
In the AMD powerplay driver, a pointer is checked for validity by
comparing against an integer '0', which causes a harmless warning
when building with "make W=1":

drivers/gpu/drm/amd/amdgpu/../powerplay/hwmgr/processpptables.c:1502:16: error: ordered comparison of pointer with integer zero [-Werror=extra]

This changes the code to the more conventional "if (pointer)" check.

ce64bc25ef drm/amdgpu: pipeline evictions as well
This boosts Xonotic from 38fps to 47fps when artificially limiting VRAM to
256MB for testing. It should improve all CPU bound rendering situations
where we have a lot of swapping to/from VRAM.

fd320bf692 drm/amdkfd: Remove create_workqueue()
alloc_workqueue replaces deprecated create_workqueue().

create_workqueue has been replaced with alloc_workqueue with max_active
as 0 since there is no need for throttling the number of active work items.

WQ_MEM_RECLAIM has not been set to because kfd_process_wq will not be
used in memory reclaim path.

kfd_process_wq is used for delay destruction. A work item embedded in
kfd_process gets queued to kfd_process_wq and when it executes it
destroys and frees the containing kfd_process and thus itself.

This requires a dedicated workqueue because a work item once queued, may
get freed at any point of time and any external entity cannot
flush the work item. So, in order to wait for such a work item,
it needs to be put on a dedicated workqueue.

kfd_module_exit() calls kfd_process_destroy_wq which ensures that all
pending work items are finished before the module is removed.

flush_workqueue is unnecessary since destroy_workqueue() itself calls
drain_workqueue() which flushes repeatedly till the workqueue
becomes empty.

Hence flush_workqueue has been removed.

2. Populate SMC ACPI minimum voltage using VBIOS boot SCLK and MCLK

When static voltage is configured as VDDCI, driver still tries to program
a voltage for MM minVoltage using VDDC-VDDCI delta requirement.
minVoltage should be set as boot up voltage.

84b89bdced drm/amdgpu: Turn off CRTCs on driver unload
amdgpu leaks a runtime pm ref if at least one CRTC is enabled on unload.
The ref is taken by amdgpu_crtc_set_config() and held as long as a CRTC
is in use. Fix by turning off all CRTCs on unload.

6ce62d8b6f drm/amdgpu: Forbid runtime pm on driver unload
The PCI core calls pm_runtime_forbid() on device probe in pci_pm_init(),
making this the default state when amdgpu is loaded.
amdgpu_driver_load_kms() therefore calls pm_runtime_allow(), but there's
no pm_runtime_forbid() in amdgpu_driver_unload_kms() to balance it. Add
it so that we leave the device in the same state that we found it.

This isn't a bug, it's just good housekeeping. When amdgpu is first
loaded with runpm=1, then unloaded and loaded again with runpm=0,
pm_runtime_forbid() will be called from amdgpu_pmops_runtime_idle() or
amdgpu_pmops_runtime_suspend(), so the behaviour is correct. If there
ever is a third party driver for AMD cards, this commit avoids that it
has to clean up behind amdgpu.

c9c9bbd754 drm/amdgpu: Don't leak runtime pm ref on driver load
If an error occurs in amdgpu_device_init() after adev->rmmio has been
set, its caller amdgpu_driver_load_kms() will skip runtime pm
initialization and call amdgpu_driver_unload_kms(), which acquires a
runtime pm ref that is leaked.

Balance by releasing a runtime pm ref in the error path of
amdgpu_driver_load_kms().

4a7885476a drm/amdgpu: Don't leak runtime pm ref on driver unload
amdgpu_driver_load_kms() calls pm_runtime_put_autosuspend() if
amdgpu_device_is_px(dev), but amdgpu_driver_unload_kms() calls
pm_runtime_get_sync() unconditionally. We therefore leak a runtime pm
ref whenever amdgpu is unloaded on a non-PX machine or if runpm=0. The
GPU will subsequently never runtime suspend after loading amdgpu again.

Fix by taking the runtime pm ref under the same condition that it was
released on driver load.

048765ad5a amdgpu: fix asic initialization for virtualized environments (v2)
When executing in a PCI passthrough based virtuzliation environemnt, the
hypervisor will usually attempt to send a PCIe bus reset signal to the
ASIC when the VM reboots. In this scenario, the card is not correctly
initialized, but we still consider it to be posted. Therefore, in a
passthrough based environemnt we should always post the card to guarantee
it is in a good state for driver initialization.

However, if we are operating in SR-IOV mode it is up to the GIM driver
to manage the asic state, therefore we should not post the card (and
shouldn't be able to do it either).

v2: add missing semi-colon

and some drivers even ignore the start parameter altogether.

This is needed for atomic drivers, where an atomic commit can

and issue for drm_atomic_helper_legacy_set_gamma, which this patch

121b78e679 drm/amdkfd: unbind only existing processes
When unbinding a process from a device (initiated by amd_iommu_v2), the
driver needs to make sure that process still exists in the process table.
There is a possibility that amdkfd's own notifier handler -
kfd_process_notifier_release() - was called before the unbind function
and it already removed the process from the process table.

v2:
Because there can be only one process with the specified pasid, and
because *p can't be NULL inside the hash_for_each_rcu macro, it is more
reasonable to just put the whole code inside the if statement that
compares the pasid value. That way, when we exit hash_for_each_rcu, we
simply exit the function as well.

76bf0db554 dma-buf/fence: make fence context 64 bit v2
Fence contexts are created on the fly (for example) by the GPU scheduler used
in the amdgpu driver as a result of an userspace request. Because of this
userspace could in theory force a wrap around of the 32bit context number
if it doesn't behave well.

Avoid this by increasing the context number to 64bits. This way even when
userspace manages to allocate a billion contexts per second it takes more
than 500 years for the context number to wrap around.

v2: fix printf formats as well.

425c452b54 drm/amd: add Kconfig dependency for ACP on DRM_AMDGPU
The DRM_AMD_ACP option doesn't have any dependencies and selects
MFD_CORE, which results in MFD_CORE=y.  Since the code is only called
from DRM_AMDGPU, it should depend on it.  Adding the dependency results
in MFD_CORE being selected as a module again if amdgpu is also a module.

9d746ab681 drm/amdgpu: Fix hdmi deep color support.
When porting the hdmi deep color detection code from
radeon-kms to amdgpu-kms apparently some kind of
copy and paste error happened, attaching an else
branch to the wrong if statement.

The result is that hdmi deep color mode is always
disabled, regardless of gpu and display capabilities and
user wishes, as the code mistakenly thinks that the display
doesn't provide the required max_tmds_clock limit and falls
back to 8 bpc.

This patch fixes deep color support, as tested on a
R9 380 Tonga Pro + suitable display, and should be
backported to all kernels with amdgpu-kms support.

amdgpu_mn_get which is called during ioct path relies on mmap_sem for
write.  If the waiting task gets killed by the oom killer it would block
oom_reaper from asynchronous address space reclaim and reduce the
chances of timely OOM resolving.  Wait for the lock in the killable mode
and return with EINTR if the task got killed while waiting.

Date:   Tue Sep 30 12:14:26 2008 -0700

    drm: Rework vblank-wait handling to allow interrupt reduction.

to stay backwards-compatible with old UMS code that didn't even tell
the kernel when it did a modeset, so that the kernel could
save/restore vblank counters. At worst this means vblanks will be
somewhat funky on a setup that very likely no one still runs.

So let's just nuke it.

Plan B would be to set it unconditionally in drm_vblank_init for kms
drivers, instead of in each driver separately. So if this patch breaks
anything please only restore the hunks in drmP.h and drm_irq.c, plus
add a check for DRIVER_MODESET in drm_vblank_init.

Stumbled over this in a discussion on irc with Chris.

local translation of the user handle to the GEM object. Let's remove the
unused parameter and save some space.

It is preferred to use ARRAY_SIZE() for size calculation, instead
using sizeof(array)/sizeof(*array). It makes the code more readable.
