HW bug description: in case of HW thread context switch
the dpc configuration of the exiting thread is dragged
one cycle into the next thread.
In order to avoid the consequences of this bug, the DPC register
is set to an initial value, and not changed afterwards.

This commit add new configuration that enables us to distinguish
between building the kernel for platforms that have a different set
of auxiliary registers for each cpu and platforms that have a shared
set of auxiliary registers across every thread in each core.
On platforms that implement a different set of auxiliary registers
disabling this configuration insures that we initialize registers on
every cpu and not just for the first thread of the core.
Example for non shared registers is working with EZsim (non silicon)

On ARC700 (and nSIM), user mode memory error triggers an L2 interrupt
which is handled gracefully by kernel (or it tries to despite this being
imprecise, and error could get charged to kernel itself). The offending
task is killed and kernel moves on.
NPS hardware however raises a Machine Check exception for same error
which is NOT recoverable by kernel.
This patch aligns kernel handling for nSIM case, to same as hardware by
overriding the default user space bus error handler.

The xen driver initializes struct ubuf_info fields using designated

Configuration Request Retry Status ("CRS") completions are a required part
of PCIe. A PCIe device may respond to config a request with a CRS
completion to indicate that it needs more time to initialize. A Root Port
that receives a CRS completion may automatically retry the request, or it
may treat the request as a failed transaction. For a failed read, it will
likely synthesize all 1's data, i.e., 0xffffffff, to complete the read to
the CPU.
CRS Software Visibility ("CRS SV") is an optional feature. Per PCIe r3.1,
sec 2.3.2, if supported and enabled, a Root Port that receives a CRS
completion for a config read of the Vendor ID will synthesize 0x0001 data
(an invalid Vendor ID) instead of retrying or failing the transaction. The
0x0001 data makes the CRS completion visible to software, so it can perform
other tasks while waiting for the device.
The iProc "Stingray" PCIe controller does not support CRS completions
correctly. From the Stingray PCIe Controller spec:
4.7.3.3. Retry Status On Configuration Cycle
Endpoints are allowed to generate retry status on configuration cycles.
In this case, the RC needs to re-issue the request. The IP does not
handle this because the number of configuration cycles needed will
probably be less than the total number of non-posted operations needed.
When a retry status is received on the User RX interface for a
configuration request that was sent on the User TX interface, it will be
indicated with a completion with the CMPL_STATUS field set to 2=CRS, and
the user will have to find the address and data values and send a new
transaction on the User TX interface. When the internal configuration
space returns a retry status during a configuration cycle (user_cscfg =
1) on the Command/Status interface, the pcie_cscrs will assert with the
pcie_csack signal to indicate the CRS status.
When the CRS Software Visibility Enable register in the Root Control
register is enabled, the IP will return the data value to 0x0001 for the
Vendor ID value and 0xffff (all 1’s) for the rest of the data in the
request for reads of offset 0 that return with CRS status. This is true
for both the User RX Interface and for the Command/Status interface.
When CRS Software Visibility is enabled, the CMPL_STATUS field of the
completion on the User RX Interface will not be 2=CRS and the pcie_cscrs
signal will not assert on the Command/Status interface.
The Stingray hardware never reissues configuration requests when it
receives CRS completions. Contrary to what sec 4.7.3.3 above says, when it
receives a CRS completion, it synthesizes 0xffff0001 data regardless of the
address of the read or the value of the CRS SV enable bit.
This is broken in two ways:
1) When CRS SV is disabled, the Root Port should never synthesize the
0x0001 value. If it receives a CRS completion, it should fail the
transaction and synthesize all 1's data.
2) When CRS SV is enabled, the Root Port should only synthesize 0x0001
data if it receives a CRS completion for a read of the Vendor ID. If it
receives a CRS completion for any other read, it should fail the
transaction and synthesize all 1's data.
This breaks pci_flr_wait(), which reads the Command register and expects to
see all 1's data if the read fails because of CRS completions. On
Stingray, it sees the incorrect 0xffff0001 data instead.
It also breaks config registers that contain the 0xffff0001 value. If we
read such a register, software can't distinguish a CRS completion from the
actual value read from the device.
On Stingray, if we read 0xffff0001 data, assume this indicates a CRS
completion and retry the read for 500ms. If we time out, return all 1's
(0xffffffff) data. Note that this corrupts registers that happen to
contain 0xffff0001.
Stingray advertises CRS SV support in its Root Capabilities register, and
the CRS SV enable bit is writable (even though the hardware ignores it).
Mask out PCI_EXP_RTCAP_CRSVIS so software doesn't try to use CRS SV.

Vulkan VkFence semantics require that the application be able to perform
a CPU wait on work which may not yet have been submitted. This is
perfectly safe because the CPU wait has a timeout which will get
triggered eventually if no work is ever submitted. This behavior is
advantageous for multi-threaded workloads because, so long as all of the
threads agree on what fences to use up-front, you don't have the extra
cross-thread synchronization cost of thread A telling thread B that it
has submitted its dependent work and thread B is now free to wait.
Within a single process, this can be implemented in the userspace driver
by doing exactly the same kind of tracking the app would have to do
using posix condition variables or similar. However, in order for this
to work cross-process (as is required by VK_KHR_external_fence), we need
to handle this in the kernel.
This commit adds a WAIT_FOR_SUBMIT flag to DRM_IOCTL_SYNCOBJ_WAIT which
instructs the IOCTL to wait for the syncobj to have a non-null fence and
then wait on the fence. Combined with DRM_IOCTL_SYNCOBJ_RESET, you can
easily get the Vulkan behavior.
v2:
- Fix a bug in the invalid syncobj error path
- Unify the wait-all and wait-any cases
v3:
- Unify the timeout == 0 case a bit with the timeout > 0 case
- Use wait_event_interruptible_timeout
v4:
- Use proxy fence
v5:
- Revert to a combination of v2 and v3
- Don't use proxy fences
- Don't use wait_event_interruptible_timeout because it just adds an
extra layer of callbacks

It is useful in certain circumstances to know when the fence is replaced
in a syncobj. Specifically, it may be useful to know when the fence
goes from NULL to something valid. This does make syncobj_replace_fence
a little more expensive because it has to take a lock but, in the common
case where there is no callback list, it spends a very short amount of
time inside the lock.
v2:

around fence_replace to make the callback work.

The atomic exchange operation in drm_syncobj_replace_fence is sufficient
for the case where it races with itself. However, if you have a race
between a replace_fence and dma_fence_get(syncobj->fence), you may end
up with the entire replace_fence happening between the point in time
where the one thread gets the syncobj->fence pointer and when it calls
dma_fence_get() on it. If this happens, then the reference may be
dropped before we get a chance to get a new one. The new helper uses
dma_fence_get_rcu_safe to get rid of the race.
This is also needed because it allows us to do a bit more than just get
a reference in drm_syncobj_fence_get should we wish to do so.
v2:
- RCU isn't that scary
- Call rcu_read_lock/unlock
- Don't rename fence to _fence

b) sglist handling doesn't optimize on the fact that each element
is a page.

If the LLDD resets or detaches from an fc port, the LLDD will
deregister all remoteports seen by the fc port and deregister the
localport associated with the fc port. The teardown of the localport
structure will be held off due to reference counting until all the
remoteports are removed (and they are held off until all
controllers/associations to terminated). Currently, if the fc port
is reinit/reattached and registered again as a localport it is
treated as an independent entity from the prior localport and all
prior remoteports and controllers cannot be revived. They are
created as new and separate entities.
This patch changes the localport registration to look at the known
localports that are waiting to be torndown. If they are the same port
based on wwn's, the local port is transitioned out of the teardown
state. This allows the remote ports and controller connections to
be reestablished and resumed as long as the localport can also be
reregistered within the timeout windows.
The patch adds a new routine nvme_fc_attach_to_unreg_lport() with
the functionality and moves the lport get/put routines to avoid
forward references.
