Use unforce levels rather than enable mask instruction.

The cursor_set2 hook provides the cursor hotspot position within the
cursor image. When the hotspot position changes, we can adjust the cursor
position such that the hotspot doesn't move on the screen. This prevents
the cursor from appearing to intermittently jump around on the screen
when the position of the hotspot within the cursor image changes.

It happens on occasion that developers of generic user-space applications
abuse the dumb buffer API to get hold of drm buffers that they can both
mmap() and use for GPU acceleration, using the assumptions that dumb buffers
and buffers available for GPU are
a) The same type and can be aribtrarily type-casted.
b) fully coherent.
This patch makes the most widely used drivers warn nicely when that happens,
the next step will be to fail.
v2: Move drmP.h changes to drm_gem.h. Fix Radeon dumb mmap breakage.

This patch adds the interrupt handling module, in kfd_interrupt.c, and its
related members in different data structures to the amdkfd driver.
The amdkfd interrupt module maintains an internal interrupt ring per amdkfd
device. The internal interrupt ring contains interrupts that needs further
handling. The extra handling is deferred to a later time through a workqueue.
There's no acknowledgment for the interrupts we use. The hardware simply queues
a new interrupt each time without waiting.
The fixed-size internal queue means that it's possible for us to lose
interrupts because we have no back-pressure to the hardware.
v3:
Move amdkfd from drm/radeon/ to drm/amd/
Change device init
Made sure spin lock is taken only if init is complete
Moved bool field to the end of the structure

The queue scheduler divides into two sections, one section is process bounded
and the other section is device bounded.
The device bounded section is handled by this module.
The DQM module handles queue setup, update and tear-down from the device side.
It also supports suspend/resume operation.
v3: Changed device_init, added the use of the new gart allocation functions an
Added documentation.
v4:
Fixed a race in DQM queue scheduler where dqm->lock must be held when accessing
dqm->queue_count and dqm->processes_count. This fixes runlist IB allocation
failures when DQM is under load.
Fixed race in DQM queue destruction where queues being destroyed must be
removed from qpd->queues_list prior to preemption, or concurrent queue
creation activity may reschedule them while their MQD is destroyed.
Fixed EOP queue size setting in CP_HPD_EOP_CONTROL, because the size is
specified as (log2(size_dwords)-1). The previous calculation assumed the
size was specified in bytes, which caused interference between EOP queues
when multiple MEC pipelines were active.

This patch adds a new parameter to the amdkfd driver. This parameter enables
the user to select the scheduling policy of the CP. The choices are:
* CP Scheduling with support for over-subscription
* CP Scheduling without support for over-subscription
* Without CP Scheduling
Note that the third option (Without CP scheduling) is only for debug purposes
and bringup of new H/W. As such, it is _not_ guaranteed to work at all times on
all H/W versions.

from a device through the amd_iommu driver.

process is released.
The bind function is not called here because it is called

This patch adds the process module and three helper modules:
- kfd_process, which handles process which open /dev/kfd
- kfd_doorbell, which provides helper functions for doorbell allocation,
release and mapping to userspace
- kfd_pasid, which provides helper functions for pasid allocation and release
- kfd_aperture, which provides helper functions for managing the LDS, Local GPU
memory and Scratch memory apertures of the process
This patch only contains the basic kfd_process module, which doesn't contain
the reference to the queue scheduler. This was done to allow easier code review.
Also, this patch doesn't contain the calls to the IOMMU driver for binding the
pasid to the device. Again, this was done to allow easier code review
The kfd_process object is created when a process opens /dev/kfd and is closed
when the mm_struct of that process is teared-down.
v3:
Removed kfd_vidmem.c file
Replaced direct mmput call to mmu_notifier release
Removed typedefs
Moved bool field to end of the structure
Added new kernel params for gart usage limitation
Added initialization of sa manager
Fixed debug messages
Remove support for LDS in 32 bit
Changed code to support mmap of doorbell pages from userspace
Added documentation for apertures
v4: Replaced RCU by SRCU for kfd_process list management
v5:
Move amdkfd from drm/radeon/ to drm/amd/
Rename kfd_aperture.c to kfd_flat_memory.c
Protect against multiple init calls
MQD size is H/W dependent so moved it to device info structure
Rename kfd_mem_obj structure's members
Use delayed function for process tear-down

This patch adds the topology module to the driver. The topology is exposed to
userspace through the sysfs.
The calls to add and remove a device to/from topology are done by the radeon
driver.
v3:
The CPU information, that is provided in the topology section of the amdkfd
driver, is extracted from the CRAT table. Unlike the CPU information located
in /sys/devices/system/cpu/cpu*, which is extracted from the SRAT table.
While the CPU information provided by the CRAT and the SRAT tables might be
identical, the node topology might be different. The SRAT table contains the
topology of CPU nodes only. The CRAT table contains the topology of CPU and GPU
nodes together (and can be interleaved). For example CPU node 1 in SRAT can be
CPU node 3 in CRAT. Furthermore it's worth to mention that the CRAT table
contains only HSA compatible nodes (nodes which are compliant with the HSA
spec).
To recap, amdkfd exposes a different kind of topology than the one exposed by
/sys/devices/system/cpu/cpu even though it may contain similar information.
v4:
The topology module doesn't support uevent handling and doesn't notify the
userspace about runtime modifications. It is up to the userspace to acquire
snapshots of the topology information created by the amdkfd and exposed
in sysfs.
The following is an example of how the topology looks on a Kaveri A10-7850K
system with amdkfd installed:
/sys/devices/virtual/kfd/kfd/
|
--- topology/
|
|--- generation_id

v5:
Move amdkfd from drm/radeon/ to drm/amd/
Add a check if dev->gpu pointer is null before accessing it in the
node_show function in kfd_topology.c
This situation may occur when amdkfd is loaded and there is a GPU with a CRAT
table, but that GPU isn't supported by amdkfd

This patch adds the interface between the radeon driver and the amdkfd driver.
The interface implementation is contained in radeon_kfd.c and radeon_kfd.h.
The interface itself is represented by a pointer to struct
kfd_dev. The pointer is located inside radeon_device structure.
All the register accesses that amdkfd need are done using this interface. This
allows us to avoid direct register accesses in amdkfd proper, while also
avoiding locking between amdkfd and radeon.
The single exception is the doorbells that are used in both of the drivers.
However, because they are located in separate pci bar pages, the danger of
sharing registers between the drivers is minimal.
Having said that, we are planning to move the doorbells as well to radeon.
v3:
Add interface for sa manager init and fini. The init function will allocate a
buffer on system memory and pin it to the GART address space via the radeon sa
manager.
All mappings of buffers to GART address space are done via the radeon sa
manager. The interface of allocate memory will use the radeon sa manager to sub
allocate from the single buffer that was allocated during the init function.
Change lower_32/upper_32 calls to use linux macros
Add documentation for the interface
v4:
Change ptr field type in kgd_mem from uint32_t* to void* to match to type that
is returned by radeon_sa_bo_cpu_addr
v5:
Change format of mqd structure to work with latest KV firmware
Add support for AQL queues creation to enable working with open-source HSA
runtime.
Move generic kfd-->kgd interface and other generic kgd definitions to a generic
header file that will be used by AMD's radeon and amdgpu drivers

This patch fixes a bug in the accounting of the device_state.
In the current code, the device_state was put (decremented) too many times,
which sometimes lead to the driver getting stuck permanently in
put_device_state_wait(). That happen because the device_state->count would go
below zero, which is never supposed to happen.
The root cause is that the device_state was decremented in put_pasid_state()
and put_pasid_state_wait() but also in all the functions that call those
functions. Therefore, the device_state was decremented twice in each of these
code paths.
The fix is to decouple the device_state accounting from the pasid_state
accounting - remove the call to put_device_state() from the
put_pasid_state() and the put_pasid_state_wait())

This notifier closes an important gap in the current mmu_notifier
implementation, the existing callbacks are called too early or too late to
reliably manage a non-CPU TLB. Specifically, invalidate_range_start() is
called when all pages are still mapped and invalidate_range_end() when all
pages are unmapped and potentially freed.
This is fine when the users of the mmu_notifiers manage their own SoftTLB,
like KVM does. When the TLB is managed in software it is easy to wipe out
entries for a given range and prevent new entries to be established until
invalidate_range_end is called.
But when the user of mmu_notifiers has to manage a hardware TLB it can
still wipe out TLB entries in invalidate_range_start, but it can't make
sure that no new TLB entries in the given range are established between
invalidate_range_start and invalidate_range_end.
To avoid silent data corruption the entries in the non-CPU TLB need to be
flushed when the pages are unmapped (at this point in time no _new_ TLB
entries can be established in the non-CPU TLB) but not yet freed (as the
non-CPU TLB may still have _existing_ entries pointing to the pages about
to be freed).
To fix this problem we need to catch the moment when the Linux VMM flushes
remote TLBs (as a non-CPU TLB is not very CPU TLB), as this is the point
in time when the pages are unmapped but _not_ yet freed.
The mmu_notifier_invalidate_range() function aims to catch that moment.
IOMMU code will be one user of the notifier-callback. Currently this is
only the AMD IOMMUv2 driver, but its code is about to be more generalized
and converted to a generic IOMMU-API extension to fit the needs of similar
functionality in other IOMMUs as well.
The current attempt in the AMD IOMMUv2 driver to work around the
invalidate_range_start/end() shortcoming is to assign an empty page table
to the non-CPU TLB between any invalidata_range_start/end calls. With the
empty page-table assigned, every page-table walk to re-fill the non-CPU
TLB will cause a page-fault reported to the IOMMU driver via an interrupt,
possibly causing interrupt storms.
The page-fault handler in the AMD IOMMUv2 driver doesn't handle the fault
if an invalidate_range_start/end pair is active, it just reports back
SUCCESS to the device and let it refault the page. But existing hardware
(newer Radeon GPUs) that makes use of this feature don't re-fault
indefinitly, after a certain number of faults for the same address the
device enters a failure state and needs to be resetted.
To avoid the GPUs entering a failure state we need to get rid of the
empty-page-table workaround and use the mmu_notifier_invalidate_range()
function introduced with this patch.
