The buffer of SA bo will be used by many cases. So it's better

Fix the following issues with SDMA RAS error reporting:
1. Read the EDC_COUNTER2 register also to fetch error counts
for all sub-blocks in SDMA.
2. SDMA RAS on Aldebaran suports single-bit uncorrectable errors
only. So, report error count in UE count instead of CE count.

If we skipped loading MEC2 firmware separately
from MEC, then MEC2 will be running the same
firmware image. Copy the MEC version and feature
numbers into MEC2 version and feature numbers.
This is needed for things like GWS support, where
we rely on knowing what version of firmware is
running on MEC2. Leaving these MEC2 entries blank
breaks our ability to version-check enables and
workarounds.

Add back the double-sscanf so that both decimal
and hexadecimal values could be read in, but this
time invert the scan so that hexadecimal format
with a leading 0x is tried first, and if that
fails, then try decimal format.
Also use a logical-AND instead of nesting double
if-conditional.

Add bad_page_cnt_threshold to debugfs, an optional
file system used for debugging, for reporting
purposes only--it usually matches the size of
EEPROM but may be different depending on the
"bad_page_threshold" kernel module option.
The "bad_page_cnt_threshold" is a dynamically
computed value. It depends on three things: the
VRAM size; the size of the EEPROM (or the size
allocated to the RAS table therein); and the
"bad_page_threshold" module parameter. It is a
dynamically computed value, when the amdgpu module
is run, on which further parameters and logic
depend, and as such it is helpful to see the
dynamically computed value in debugfs.

"retire_page", which caused the kernel to recall
the method with *pos == end of file, and that

also a bug.
Fix the logic of the check of the result of

and non-zero on error, not the other way
around. This patch fixes this bug.

Remove double-sscanf to scan for %llu and 0x%llx,
as that is not going to work!
The %llu will consume the "0" in "0x" of your
input, and the hex value you think you're entering
will always be 0. That is, a valid hex value can
never be consumed.
On the other hand, just entering a hex number
without leading 0x will either be scanned as a
string and not match, for instance FAB123, or
the leading decimal portion is scanned as the
%llu, for instance 123FAB will be scanned as 123,
which is not correct.
Thus remove the first %llu scan and leave only the
%llx scan, removing the leading 0x since %llx can
scan either.
Addresses are usually always hex values, so this
suffices.

Add emit mem sync callback for sdma_v5_2
In amdgpu sync object test, three threads created jobs
to send GFX IB and SDMA IB in sequence. After the first
GFX thread joined, sometimes the third thread will reuse
the same physical page to store the SDMA IB. There will
be a risk that SDMA will read GFX IB in the previous physical
page. So it's better to flush the cache before commit sdma IB.
