‘ds_port’ is clearly not used anywhere and ‘result_write_min_hblank’ is
only utilised when debugging is enabled. The alternative would be to
allocate the variable under the same clause as the debugging code, but
that would become very messy, very quickly.

Refactor register_backlight_device():
1) Turn the connector-type + signal check into an early exit
condition to avoid the indentation level of the rest of the code
2) Add an array bounds check for the arrays indexed by dm->num_of_edps
3) register_backlight_device() always increases dm->num_of_edps if
amdgpu_dm_register_backlight_device() has assigned a backlight_dev to
the current dm->backlight_link[dm->num_of_edps] slot.
So on its next call dm->backlight_dev[dm->num_of_edps] always point to
the next empty slot and the "if (!dm->backlight_dev[dm->num_of_edps])"
check will thus always succeed and can be removed.
4) Add a bl_idx local variable to use as array index, rather then
using dm->num_of_edps to improve the code readability.

backlight_device_register() returns an ERR_PTR on error, but other code
such as amdgpu_dm_connector_destroy() assumes dm->backlight_dev[i] is NULL
if no backlight is registered.
Clear dm->backlight_dev[i] on registration failure, to avoid other code
trying to deref an ERR_PTR pointer.

[Why]
For engines not supporting soft reset, i.e. VCN, there will be a failed
ib test before mode 1 reset during asic reset. The fences in this case
are never signaled and next time when we try to free the sa_bo, kernel
will hang.
[How]
During pre_asic_reset, driver will clear job fences and afterwards the
fences' refcount will be reduced to 1. For drm_sched_jobs it will be
released in job_free_cb, and for non-sched jobs like ib_test, it's meant
to be released in sa_bo_free but only when the fences are signaled. So
we have to force signal the non_sched bad job's fence during
pre_asic_reset or the clear is not complete.

The lack of a definition for this counter is what initially prompted me
to investigate a problem which really manifested itself as the previous
change, "net: mscc: ocelot: fix transfer from region->buf to ocelot->stats".
When TX_MM_HOLD is defined in enum ocelot_stat but not in struct
ocelot_stat_layout ocelot_mm_stats_layout, this creates a hole, which
due to the aforementioned bug, makes all counters following TX_MM_HOLD
be recorded off by one compared to their correct position. So for
example, a non-zero TX_PMAC_OCTETS would be reported as TX_MERGE_FRAGMENTS,
TX_PMAC_UNICAST would be reported as TX_PMAC_OCTETS, TX_PMAC_64 would be
reported as TX_PMAC_PAUSE, etc etc. This is because the size of the hole
(1) is much smaller than the size of the region, so the phenomenon where
the stats are off-by-one, rather than lost, prevails.
However, the phenomenon where stats are lost can be seen too, for
example with DROP_LOCAL, which is at the beginning of its own region
(offset 0x000400 vs the previous 0x0002b0 constitutes a discontinuity).
This is also reported as off by one and saved to TX_PMAC_1527_MAX, but
that counter is not reported to the unstructured "ethtool -S", as
opposed to DROP_LOCAL which is (as "drop_local").

To understand the problem, we need some definitions.
The driver is aware of multiple counters (enum ocelot_stat), yet not all
switches supported by the driver implement all counters. There are 2
statistics layouts: ocelot_stats_layout and ocelot_mm_stats_layout, the
latter having 36 counters more than the former.
ocelot->stats[] is not a compact array, i.e. there are elements within
it which are not going to be populated for ocelot_stats_layout. On the
other hand, ocelot->stats[] is easily indexable, for example "tx_octets"
for port 3 can be found at ocelot->stats[3 * OCELOT_NUM_STATS +
OCELOT_STAT_TX_OCTETS], and that is why we keep it sparse.
Regions, as created by ocelot_prepare_stats_regions(), are compact
(every element from region->buf will correspond to a counter that is
present in this switch's layout) but are not easily indexable.
Let's define holes as the ranges of values of enum ocelot_stat for which
ocelot_stats_layout doesn't have a "reg" defined. For example, there is
a hole between OCELOT_STAT_RX_GREEN_PRIO_7 and OCELOT_STAT_TX_OCTETS
which is of 23 elements that are only present on ocelot_mm_stats_layout,
and as such, they are also present in enum ocelot_stat. Let's define the
left extremity of the hole - the last enum ocelot_stat still defined -
as A (in this case OCELOT_STAT_RX_GREEN_PRIO_7) and the right extremity -
the first enum ocelot_stat that is defined after a series of undefined
ones - as B (in this case OCELOT_STAT_TX_OCTETS).
There is a bug in the procedure which transfers stats from region->buf[]
to ocelot->stats[].
For each hole in the ocelot_stats_layout, the logic transfers the stats
starting with enum ocelot_stat B to ocelot->stats[] index A + 1. So all
stats after a hole are saved to a position which is off by B - A + 1
elements.
This causes 2 kinds of issues:
(a) counters which shouldn't increment increment
(b) counters which should increment don't
Holes in the ocelot_stat_layout automatically imply the end of a region
and the beginning of a new one; however the reverse is not necessarily
true. For example, for ocelot_mm_stat_layout, there could be multiple
regions (which indicate discontinuities in register addresses) while
there is no hole (which indicates discontinuities in enum ocelot_stat
values).
In the example above, the stats from the second region->buf[] are not
transferred to ocelot->stats starting with index
"port * OCELOT_NUM_STATS + OCELOT_STAT_TX_OCTETS" as they should, but
rather, starting with element
"port * OCELOT_NUM_STATS + OCELOT_STAT_RX_GREEN_PRIO_7 + 1".
That stats[] array element is not reported to user space for switches
that use ocelot_stat_layout, and that is how issue (b) occurs.
However, if the length of the second region is larger than the hole,
then some stats will start to be transferred to the ocelot->stats[]
indices which *are* reported to user space, but those indices contain
wrong values (corresponding to unexpected counters). This is how issue
(a) occurs.
The procedure, as it was introduced in commit d87b1c08f38a ("net: mscc:
ocelot: use bulk reads for stats"), was not buggy, because there were no
holes in the struct ocelot_stat_layout instances at that time. The
problem is that when those holes were introduced, the function was not
updated to take them into consideration.
To update the procedure, we need to know, for each region, which enum
ocelot_stat corresponds to its region->base. We have no way of deducing
that based on the contents of struct ocelot_stats_region, so we need to
add this information.

The blamed commit changed struct ocelot_stat_layout :: "u32 offset" to
"u32 reg".
However, "u32 reg" is not quite a register address, but an enum
ocelot_reg, which in itself encodes an enum ocelot_target target in the
upper bits, and an index into the ocelot->map[target][] array in the
lower bits.
So, whereas the previous code comparison between stats_layout[i].offset
and last + 1 was correct (because those "offsets" at the time were
32-bit relative addresses), the new code, comparing layout[i].reg to
last + 4 is not correct, because the "reg" here is an enum/index, not an
actual register address.
What we want to compare are indeed register addresses, but to do that,
we need to actually go through the same motions as
__ocelot_bulk_read_ix() itself.
With this bug, all statistics counters are deemed by
ocelot_prepare_stats_regions() as constituting their own region.
(Truncated) log on VSC9959 (Felix) below (prints added by me):
Before:
region of 1 contiguous counters starting with SYS:STAT:CNT[0x000]
region of 1 contiguous counters starting with SYS:STAT:CNT[0x001]
region of 1 contiguous counters starting with SYS:STAT:CNT[0x002]
...

region of 45 contiguous counters starting with SYS:STAT:CNT[0x080]
region of 18 contiguous counters starting with SYS:STAT:CNT[0x100]
Since commit d87b1c08f38a ("net: mscc: ocelot: use bulk reads for
stats") intended bulking as a performance improvement, and since now,
with trivial-sized regions, performance is even worse than without
bulking at all, this could easily qualify as a performance regression.

The root cause is traced to the vc_maps which alloced in open_card_oam()
are not freed in close_card_oam(). The vc_maps are used to record
open connections, so when close a vc_map in close_card_oam(), the memory
should be freed. Moreover, the ubr0 is not closed when close a idt77252
device, leading to the memory leak of vc_map and scq_info.
Fix them by adding kfree in close_card_oam() and implementing new
close_card_ubr0() to close ubr0.

This tag contains habanalabs driver and accel changes for v6.4:
- uAPI changes:
- Add opcodes to the CS ioctl to allow user to stall/resume specific engines
inside Gaudi2. This is to allow the user to perform power
testing/measurements when training different topologies.
- Expose in the INFO ioctl the amount of device memory that the driver
and f/w reserve for themselves.
- Expose in the INFO ioctl a bit-mask of the available rotator engines
in Gaudi2. This is to align with other engines that are already exposed.
- Expose in the INFO ioctl the register's address of the f/w that should
be used to trigger interrupts from within the user's code running in the
compute engines.
- Add a critical-event bit in the eventfd bitmask so the user will know the
event that was received was critical, and a reset will now occur
- Expose in the INFO ioctl two new opcodes to fetch information on h/w and
f/w events. The events recorded are the events that were reported in the
eventfd.
- New features and improvements:
- Add a dedicated interrupt ID in MSI-X in the device to the notification of
an unexpected user-related event in Gaudi2. Handle it in the driver by
reporting this event.
- Allow the user to fetch the device memory current usage even when the
device is undergoing compute-reset (a reset type that only clears the
compute engines).
- Enable graceful reset mechanism for compute-reset. This will give the
user a few seconds before the device is reset. For example, the user can,
during that time, perform certain device operations (dump data for debug)
or close the device in an orderly fashion.
- Align the decoder with the rest of the engines in regard to notification
to the user about interrupts and in regard to performing graceful reset
when needed (instead of immediate reset).
- Add support for assert interrupt from the TPC engine.
- Get the reset type that is necessary to perform per event from the
auto-generated irq_map array.
- Print the specific reason why a device is still in use when notifying to
the user about it (after the user closed the device's FD).
- Move to threaded IRQ when handling interrupts of workload completions.
- Firmware related fixes:
- Fix RAZWI event handler to match newest f/w version.
- Read error cause register in dma core events because the f/w doesn't
do that.
- Increase maximum time to wait for completion of Gaudi2 reset due to f/w
bug.
- Align to the latest firmware specs.
- Enforce the release order of the compute device and dma-buf.
i.e increment the device file refcount for any dma-buf that was exported
for that device. This will make sure the compute device release function
won't be called until the user closes all the FDs of the relevant
dma-bufs. Without this change, closing the device's FD before/without
closing the dma-buf's FD would always lead to hard-reset of the device.
- Fix a link in the drm documentation to correctly point to the accel section.
- Compilation warnings cleanups
- Misc bug fixes and code cleanups

Upon entering switchdev mode, VF/SF representors are spawned in the
devlink instance's net namespace, whereas the PF net device transforms
into the uplink representor, remaining in the net namespace the PF net
device was in. Therefore, if a PF net device's namespace is different from
its parent devlink net namespace, entering switchdev mode can create an
illegal situation where all representors sharing the same core device
are NOT in the same net namespace.
To avoid this issue, block entering switchdev mode for devices whose child
netdev net namespace has diverged from the parent devlink's.

Previously, NETNS_LOCAL was not set for uplink representors, inconsistent
with VF representors, and allowed the uplink representor to be moved
between net namespaces and separated from the VF representors it shares
the core device with. Such usage would break the isolation model of
namespaces, as devices in different namespaces would have access to
shared memory.
To solve this issue, set NETNS_LOCAL for uplink representors if eswitch is
in switchdev mode.

When a system with E810 with existing VFs gets rebooted the following
hang may be observed.
Pid 1 is hung in iavf_remove(), part of a network driver:

During reboot all drivers PM shutdown callbacks are invoked.
In iavf_shutdown() the adapter state is changed to __IAVF_REMOVE.
In ice_shutdown() the call chain above is executed, which at some point
calls iavf_remove(). However iavf_remove() expects the VF to be in one
of the states __IAVF_RUNNING, __IAVF_DOWN or __IAVF_INIT_FAILED. If
that's not the case it sleeps forever.
So if iavf_shutdown() gets invoked before iavf_remove() the system will
hang indefinitely because the adapter is already in state __IAVF_REMOVE.
Fix this by returning from iavf_remove() if the state is __IAVF_REMOVE,
as we already went through iavf_shutdown().

Filters shouldn't be removed in VSI rebuild path. Removing them on PF
VSI results in no rule for PF MAC after changing for example queues
amount.
Remove all filters only in the VSI remove flow. As unload should also
cause the filter to be removed introduce, a new function ice_stop_eth().
It will unroll ice_start_eth(), so remove filters and close VSI.
