e7e4785fa3 selftests: net: test_vxlan_under_vrf: fix HV connectivity test
It looks like test_vxlan_under_vrf.sh is always failing to verify the
connectivity test during the ping between the two simulated VMs.

This is due to the fact that veth-hv in each VM should have a distinct
MAC address.

Fix by setting a unique MAC address on each simulated VM interface.

Without this fix:

 $ sudo ./tools/testing/selftests/net/test_vxlan_under_vrf.sh
 Checking HV connectivity                                           [ OK ]
 Check VM connectivity through VXLAN (underlay in the default VRF)  [FAIL]

With this fix applied:

 $ sudo ./tools/testing/selftests/net/test_vxlan_under_vrf.sh
 Checking HV connectivity                                           [ OK ]
 Check VM connectivity through VXLAN (underlay in the default VRF)  [ OK ]
 Check VM connectivity through VXLAN (underlay in a VRF)            [FAIL]

NOTE: the connectivity test with the underlay VRF is still failing; it
seems that ARP requests are blocked at the simulated hypervisor level,
probably due to some missing ARP forwarding rules. This requires more
investigation (in the meantime we may consider to set that test as
expected failure - XFAIL).

Currently, driver only allow configuring ETS bandwidth of TCs according
to the max TC number queried from firmware. However, the hardware actually

1122eac194 net: hns3: fix some mac statistics is always 0 in device version V2
When driver queries the register number of mac statistics from firmware,
the old firmware runs in device version V2 only returns number of valid
registers, not include number of three reserved registers among of them.
It cause driver doesn't record the last three data when query mac
statistics.

To fix this problem, driver never query register number in device version
V2 and set it to a fixed value which include three reserved registers.

3b6db4a049 net: hns3: sync rx ring head in echo common pull
When the driver processes rx packets, the head pointer is updated only
after the number of received packets reaches 16. However, hardware
relies on the head pointer to calculate the number of FBDs. As a result,
the hardware calculates the FBD incorrectly. Therefore, the driver
proactively updates the head pointer in each common poll to ensure that
the number of FBDs calculated by the hardware is correct.

0b653a81a2 net: hns3: fix pfc packet number incorrect after querying pfc parameters
Currently, driver will send command to firmware to query pfc packet number
when user uses dcb tool to get pfc parameters. However, the periodic
service task will also periodically query and record MAC statistics,
including pfc packet number.

As the hardware registers of statistics is cleared after reading, it will
cause pfc packet number of MAC statistics are not correct after using dcb
tool to get pfc parameters.

To fix this problem, when user uses dcb tool to get pfc parameters, driver
updates MAC statistics firstly and then get pfc packet number from MAC
statistics.

3b4c6566c1 net: hns3: fix failed to add reuse multicast mac addr to hardware when mc mac table is full
Currently, when driver is failed to add a new multicast mac address to
hardware due to the multicast mac table is full, it will directly return.
In this case, if the multicast mac list has some reuse addresses after the
new address, those reuse addresses will never be added to hardware.

To fix this problem, if function hclge_add_mc_addr_common() returns
-ENOSPC, hclge_sync_vport_mac_list() should judge whether continue or
stop to add next address.

As function hclge_sync_vport_mac_list() needs parameter mac_type to know
whether is uc or mc, refine this function to add parameter mac_type and
remove parameter sync. So does function hclge_unsync_vport_mac_list().

Modern devices may redraw display at 60 Hz, make sure we have one input
sample per one frame. Reduce sample period to 15ms, so we would get up
to 66.6 samples per second, although realistically with all the jitter
and extra scheduling wiggle room, we would end up just above 60 samples

and sampling too seldom.

8639e042ad Input: ili210x - improve polled sample spacing
Currently the ili210x driver implements a threaded interrupt handler which
starts upon edge on the interrupt line, and then polls the touch controller
for samples. Every time a sample is obtained from the controller, the thread
function checks whether further polling is required, and if so, waits fixed
amount of time before polling for next sample.

The delay between consecutive samples can thus vary greatly, because the
I2C transfer required to retrieve the sample from the controller takes
different amount of time on different platforms. Furthermore, different
models of the touch controllers supported by this driver require different
delays during retrieval of samples too.

Instead of waiting fixed amount of time before polling for next sample,
determine how much time passed since the beginning of sampling cycle and
then wait only the remaining amount of time within the sampling cycle.
This makes the driver deliver samples with equal spacing between them.

43aa493799 amt: use cancel_delayed_work() instead of flush_delayed_work() in amt_fini()
When the amt module is being removed, it calls flush_delayed_work() to exit
source_gc_wq. But it wouldn't be exited properly because the
amt_source_gc_work(), which is the callback function of source_gc_wq
internally calls mod_delayed_work() again.
So, amt_source_gc_work() would be called after the amt module is removed.
Therefore kernel panic would occur.
In order to avoid it, cancel_delayed_work() should be used instead of
flush_delayed_work().

Test commands:
   modprobe amt
   modprobe -rv amt

Splat looks like:

Tell the RTC core UIE are not supported because the resolution of the alarm
is a minute.

Note that this is in fact also fixing how the resolution is reported as the
previous test was simply ensuring the alarm was more than a minute in the
future while the register has a minute resolution.
This would be ok if the alarm was a countdown but ab8500_rtc_read_alarm
suggests otherwise and the AB8500 datasheet states that the RTC
documentation is not public.

Finally, the comment is wrong and what makes the UIE emulation work is
uie_unsupported being set.

c40a09e56f drm/amd/display: Add callbacks for DMUB HPD IRQ notifications
[Why]
We need HPD IRQ notifications (RX, short pulse) to properly handle
DP MST for DPIA connections.

[How]
A null pointer exception currently occurs when these are received
so add a check to validate that we have a handler installed for
the notification.

Extend the HPD handler to also handle HPD IRQ (RX) since the logic is
the same.

d82b3266ef drm/amd/display: Don't lock connection_mutex for DMUB HPD
[Why]
Per DRM spec we only need to hold that lock when touching
connector->state - which we do not do in that handler.

Taking this locking introduces unnecessary dependencies with other
threads which is bad for performance and opens up the potential for
a deadlock since there are multiple locks being held at once.

[How]
Remove the connection_mutex lock/unlock routine and just iterate over
the drm connectors normally. The iter helpers implicitly lock the
connection list so this is safe to do.

DC link access also does not need to be guarded since the link
table is static at creation - we don't dynamically add or remove links,
just streams.

a44fe9ee05 drm/amdkfd: Fix retry fault drain race conditions
The check for whether to drain retry faults must be under the mmap write
lock to serialize with munmap notifier callbacks.

We were also missing checks on child ranges. To fix that, simplify the
logic by using a flag rather than checking on each prange. That also
allows draining less freqeuntly when many ranges are unmapped at once.

3aac6aa630 drm/amdkfd: lower the VAs base offset to 8KB
The low 16MB of virtual address space are currently reserved for kernel
mode allocations mapped into user virtual address space. This causes
conflicts with HMM/SVM mappings at low virtual addresses. We tried to
move those kernel mode allocations to the upper half of the 64-bit
virtual address space for GFX9, which is naturally reserved for kernel
use. However, TBA (trap handler code) has problems to access addresses
in the high virtual space. We have decided to set this to 8KB of the
lower address space as a temporary fix, while investigate TBA address
problem. It is very unlikely for user space to map memory at this low
region.
