Currently we are using hardcoded 7 for io and fast wake lines.
According to Bspec io and fast wake times are both 42us for
DISPLAY_VER >= 12 and 50us and 32us for older platforms.
Calculate line counts for these and configure them into PSR2_CTL
accordingly
Use 45 us for the fast wake calculation as 42 seems to be too
tight based on testing.

Enable damage clipping on the primary plane and iterate over small
areas of reported framebuffer damage. Avoid the overhead of permanent
full-screen updates that cirrus currently implements.
This problem is indicated by the warning
drm_plane_enable_fb_damage_clips() not called
in the kernel's log. Without damage clipping, drivers do full updates
of the screen area. This is costly as many screen updates, such as
cursor movement or command-line input, only change a small portion
of the output. Damage clipping allows renderers to inform drivers about
the changed areas.
With the damage information known, cirrus now iterates over a list of
change areas and only flushes those to the hardware's scanout buffer.

Replace simple-KMS helpers with DRM's regular helpers for atomic
modesetting. Avoids the mid-layer and the additional wrappers around
GEM's shadow-plane helpers.
Most of the simple-KMS code is just wrappers around regular atomic
helpers. The conversion is therefore equivalent to pulling the
simple-KMS helpers into cirrus and removing all the intermediate
code and data structures between the driver and the atomic helpers.
As the simple-KMS helpers lump primary plan, CRTC and encoder into a
single data structure, the conversion to regular helpers allows to
split modesetting from plane updates and handle each individually.

On s390 PCI functions may be hotplugged individually even when they
belong to a multi-function device. In particular on an SR-IOV device VFs
may be removed and later re-added.
In commit a50297cf8235 ("s390/pci: separate zbus creation from
scanning") it was missed however that struct pci_bus and struct
zpci_bus's resource list retained a reference to the PCI functions MMIO
resources even though those resources are released and freed on
hot-unplug. These stale resources may subsequently be claimed when the
PCI function re-appears resulting in use-after-free.
One idea of fixing this use-after-free in s390 specific code that was
investigated was to simply keep resources around from the moment a PCI
function first appeared until the whole virtual PCI bus created for
a multi-function device disappears. The problem with this however is
that due to the requirement of artificial MMIO addreesses (address
cookies) extra logic is then needed to keep the address cookies
compatible on re-plug. At the same time the MMIO resources semantically
belong to the PCI function so tying their lifecycle to the function
seems more logical.
Instead a simpler approach is to remove the resources of an individually
hot-unplugged PCI function from the PCI bus's resource list while
keeping the resources of other PCI functions on the PCI bus untouched.
This is done by introducing pci_bus_remove_resource() to remove an
individual resource. Similarly the resource also needs to be removed
from the struct zpci_bus's resource list. It turns out however, that
there is really no need to add the MMIO resources to the struct
zpci_bus's resource list at all and instead we can simply use the
zpci_bar_struct's resource pointer directly.

Starting from an used_idx different than 0 is needed in use cases like
virtual machine migration. Not doing so and letting the caller set an
avail idx different than 0 causes destination device to try to use old
buffers that source driver already recover and are not available
anymore.
Since vdpa_sim does not support receive inflight descriptors as a
destination of a migration, let's set both avail_idx and used_idx the
same at vq start. This is how vhost-user works in a
VHOST_SET_VRING_BASE call.
Although the simple fix is to set last_used_idx at vdpasim_set_vq_state,
it would be reset at vdpasim_queue_ready. The last_avail_idx case is
fixed with commit 0e84f918fac8 ("vdpa_sim: not reset state in
vdpasim_queue_ready"). Since the only option is to make it equal to
last_avail_idx, adding the only change needed here.
This was discovered and tested live migrating the vdpa_sim_net device.

Currently vhost_vdpa_cleanup() unmaps the DMA mappings by calling
`iommu_unmap(v->domain, map->start, map->size);`
from vhost_vdpa_general_unmap() when the parent vDPA driver doesn't
provide DMA config operations.
However, the IOMMU domain referred to by `v->domain` is freed in
vhost_vdpa_free_domain() before vhost_vdpa_cleanup() in
vhost_vdpa_release() which results in NULL pointer de-reference.
Accordingly, moving the call to vhost_vdpa_free_domain() in
vhost_vdpa_cleanup() would makes sense. This will also help
detaching the dma device in error handling of vhost_vdpa_alloc_domain().
This issue was observed on terminating QEMU with SIGQUIT.

AMD has issued an advisory indicating that having fTPM enabled in
BIOS can cause "stuttering" in the OS. This issue has been fixed
in newer versions of the fTPM firmware, but it's up to system
designers to decide whether to distribute it.
This issue has existed for a while, but is more prevalent starting
with kernel 6.1 because commit b006c439d58db ("hwrng: core - start
hwrng kthread also for untrusted sources") started to use the fTPM
for hwrng by default. However, all uses of /dev/hwrng result in
unacceptable stuttering.
So, simply disable registration of the defective hwrng when detecting
these faulty fTPM versions. As this is caused by faulty firmware, it
is plausible that such a problem could also be reproduced by other TPM
interactions, but this hasn't been shown by any user's testing or reports.
It is hypothesized to be triggered more frequently by the use of the RNG
because userspace software will fetch random numbers regularly.
Intentionally continue to register other TPM functionality so that users
that rely upon PCR measurements or any storage of data will still have
access to it. If it's found later that another TPM functionality is
exacerbating this problem a module parameter it can be turned off entirely
and a module parameter can be introduced to allow users who rely upon
fTPM functionality to turn it on even though this problem is present.

When probing the ucd90320 access to some of the registers randomly fails.
Sometimes it NACKs a transfer, sometimes it returns just random data and
the PEC check fails.
Experimentation shows that this seems to be triggered by a register access
directly back to back with a previous register write. Experimentation also
shows that inserting a small delay after register writes makes the issue go
away.
Use a similar solution to what the max15301 driver does to solve the same
problem. Create a custom set of bus read and write functions that make sure
that the delay is added.

The fixes are:
- rtl8192e driver fixes for where the driver was attempting to

- rtl8723bs driver fixes for issues found by Hans in testing
The deleted driver is the removal of the r8188eu wireless driver as
now in 6.3-rc1 we have a "real" wifi driver for one that includes
support for many many more devices than this old driver did. So it's
time to remove it as it is no longer needed. The maintainers of this
driver all have acked its removal. Many thanks to them over the years
for working to clean it up and keep it working while the real driver
was being developed.

If the driver detects during probe that firmware is in recovery
mode then i40e_init_recovery_mode() is called and the rest of
probe function is skipped including pci_set_drvdata(). Subsequent
i40e_shutdown() called during shutdown/reboot dereferences NULL
pointer as pci_get_drvdata() returns NULL.
To fix call pci_set_drvdata() also during entering to recovery mode.
Reproducer:
1) Lets have i40e NIC with firmware in recovery mode
2) Run reboot

For l3s mode, skb->dev is set to ipvlan interface in ipvlan_nf_input():
skb->dev = addr->master->dev
but, skb->skb_iif remain unchanged, this will cause socket lookup failed
if a target socket is bound to a interface, like the following example:
ip link add ipvlan0 link eth0 type ipvlan mode l3s
ip addr add dev ipvlan0 192.168.124.111/24
ip link set ipvlan0 up
ping -c 1 -I ipvlan0 8.8.8.8
100% packet loss
This is because there is no match sk in __raw_v4_lookup() as sk->sk_bound_dev_if != dif(skb->skb_iif).
Fix this by make skb->skb_iif track skb->dev in ipvlan_nf_input().

The CI results for the 'fast request' patch set (enables error return
codes for fire-and-forget H2G messages) hit an issue with the KMD
sending context submission requests on an invalid context. That was
caused by a fault injection probe failing the context creation of a
kernel context. However, there was no return code checking on any of
the kernel context registration paths. So the driver kept going and
tried to use the kernel context for the record defaults process.
This would not cause any actual problems. The invalid requests would
be rejected by GuC and ultimately the start up sequence would
correctly wedge due to the context creation failure. But fixing the
issue correctly rather ignoring it means we won't get CI complaining
when the fast request patch lands and enables the extra error checking.
So fix it by checking for errors and aborting as appropriate when
creating kernel contexts. While at it, clean up some other submission
init related failure cleanup paths. Also, rename guc_init_lrc_mapping
to guc_init_submission as the former name hasn't been valid in a long
time.
