Until now the emmc worked when booting because the bootrom set up the
pin config correctly to load the initial bootloader from it.
So when the kernel started it "just" reused this setup but never made
sure it was actually correct.
This then breaks when the system is started via some other means, like
downloading the initial bootloader via the bootrom usb download.
With actual emmc pin-config added, barebox is able to access the eMMC
even when booted via USB.

The differences in the vendor-approved CPU and GPU OPPs for the standard
Rockchip RK3588 variant [1] and the industrial Rockchip RK3588J variant [2]
come from the latter, presumably, supporting an extended temperature range
that's usually associated with industrial applications, despite the two SoC
variant datasheets specifying the same upper limit for the allowed ambient
temperature for both variants. However, the lower temperature limit is
specified much lower for the RK3588J variant. [1][2]
To be on the safe side and to ensure maximum longevity of the RK3588J SoCs,
only the CPU and GPU OPPs that are declared by the vendor to be always safe
for this SoC variant may be provided. As explained by the vendor [3] and
according to the RK3588J datasheet, [2] higher-frequency/higher-voltage
CPU and GPU OPPs can be used as well, but at the risk of reducing the SoC
lifetime expectancy. Presumably, using the higher OPPs may be safe only
when not enjoying the assumed extended temperature range that the RK3588J,
as an SoC variant targeted specifically at higher-temperature, industrial
applications, is made (or binned) for.
Anyone able to keep their RK3588J-based board outside the above-presumed
extended temperature range at all times, and willing to take the associated
risk of possibly reducing the SoC lifetime expectancy, is free to apply
a DT overlay that adds the higher CPU and GPU OPPs.
With all this and the downstream RK3588(J) DT definitions [4][5] in mind,
let's delete the RK3588J CPU and GPU OPPs that are not considered belonging
to the normal operation mode for this SoC variant. To quote the RK3588J
datasheet [2], "normal mode means the chipset works under safety voltage
and frequency; for the industrial environment, highly recommend to keep in
normal mode, the lifetime is reasonably guaranteed", while "overdrive mode
brings higher frequency, and the voltage will increase accordingly; under
the overdrive mode for a long time, the chipset may shorten the lifetime,
especially in high-temperature condition".
To sum the RK3588J datasheet [2] and the vendor-provided DTs up, [4][5]
the maximum allowed CPU core, GPU and NPU frequencies are as follows:
IP core | Normal mode | Overdrive mode
------------+-------------+----------------
Cortex-A55 | 1,296 MHz | 1,704 MHz
Cortex-A76 | 1,608 MHz | 2,016 MHz
GPU | 700 MHz | 850 MHz
NPU | 800 MHz | 950 MHz
Unfortunately, when it comes to the actual voltages for the RK3588J CPU and
GPU OPPs, there's a discrepancy between the RK3588J datasheet [2] and the
downstream kernel code. [4][5] The RK3588J datasheet states that "the max.
working voltage of CPU/GPU/NPU is 0.75 V under the normal mode", while the
downstream kernel code actually allows voltage ranges that go up to 0.95 V,
which is still within the voltage range allowed by the datasheet. However,
the RK3588J datasheet also tells us to "strictly refer to the software
configuration of SDK and the hardware reference design", so let's embrace
the voltage ranges provided by the downstream kernel code, which also
prevents the undesirable theoretical outcome of ending up with no usable
OPPs on a particular board, as a result of the board's voltage regulator(s)
being unable to deliver the exact voltages, for whatever reason.
The above-described voltage ranges for the RK3588J CPU OPPs remain taken
from the downstream kernel code [4][5] by picking the highest, worst-bin
values, which ensure that all RK3588J bins will work reliably. Yes, with
some power inevitably wasted as unnecessarily generated heat, but the
reliability is paramount, together with the longevity. This deficiency
may be revisited separately at some point in the future.
The provided RK3588J CPU OPPs follow the slightly debatable "provide only
the highest-frequency OPP from the same-voltage group" approach that's been
established earlier, [6] as a result of the "same-voltage, lower-frequency"
OPPs being considered inefficient from the IPA governor's standpoint, which
may also be revisited separately at some point in the future.

The RK3588 thermal sensor driver only receives interrupts when a
higher-temperature threshold is crossed; it cannot notify when the
sensor cools back off. As a result, the driver must poll for temperature
changes to detect when the conditions for a thermal trip are no longer
met. However, it only does so if the DT enables polling.
Before this patch, the RK1 DT did not enable polling, causing the fan to
continue running at the speed corresponding to the highest temperature
reached.
Follow suit with similar RK3588 boards by setting a polling-delay of
1000ms, enabling the driver to detect when the sensor cools back off,
allowing the fan speed to decrease as appropriate.

__VA_OPT__ is a macro that is useful when some arguments can be present
or not to entirely skip some part of a definition. Unfortunately, it
is a too recent addition that some of the still supported old GCC
versions do not know about, and is anyway not part of C11 that is the
version used in the kernel.
Find a trick to remove this macro, typically '__VA_ARGS__ + 0' is a
workaround used in netlink.h which works very well here, as we either
expect:
- 0
- A positive value
- No value, which means the field should be 0.

The RZ/G2L driver utilises the VSPD to read data from input sources.
The rzg2l_du_kms component lists a restricted subset of the capabilities
of the VSPD which prevents additional formats from being used for
display planes.
The supported display plane formats are mapped in rzg2l_du_vsp_formats[].
Extend the rzg2l_du_format_infos[] table with the corresponding mappings
between the supported DRM formats and the formats exposed by the VSP in
rzg2l_du_vsp_formats, maintaining the same ordering in both tables.
The RPF module on VSPD supports various format conversion and send the

Commit 61167ad5fecd ("mm: pass nid to reserve_bootmem_region()") introduce
a way to set nid to all reserved region.
But there is a corner case it will leave some region with invalid nid.
When memblock_set_node() doubles the array of memblock.reserved, it may
lead to a new reserved region before current position. The new region
will be left with an invalid node id.
Repeat the process when detecting it.

The second parameter of memblock_set_node() is size instead of end.
Since it iterates from lower address to higher address, finally the node
id is correct. But during the process, some of them are wrong.
Pass size instead of end.

We need to access the PMIC during late system shutdown and at that time
we are not allowed to sleep anymore.
To make this case work, and since we can't detect this case in a
non-racy way, switch to using udelay() unconditionally, instead of
usleep_range().

acpm_dequeue_by_polling() uses a loop counter and assumes that each
iteration of the loop takes 20us. It may take longer, though, because
usleep_range() may sleep a different amount.
Switch to using ktime_get() / ktime_before() to detect the timeout
condition more reliably.
This change also makes the code easier to follow and it allows us to
adjust the sleep if necessary, without having to adjust the loop
counter exit condition.

It's not enough to have a dependency on CONFIG_FB, as that can be in
a loadable module when vivid itself is builtin:

vivid-osd.c:(.text+0xdc0): undefined reference to `fb_alloc_cmap'
vivid-osd.c:(.text+0xe26): undefined reference to `register_framebuffer'
Change the dependency to only allow configurations that can be built,
but change the FB to FB_CORE so this is also possible when using
DRM with FB compatibility rather than full fbdev.

When mounting the same share twice, once with the "linux" mount parameter
(or equivalently "posix") and then once without (or e.g. with "nolinux"),
we were incorrectly reusing the same tree connection for both mounts.
This meant that the first mount of the share on the client, would
cause subsequent mounts of that same share on the same client to
ignore that mount parm ("linux" vs. "nolinux") and incorrectly reuse
the same tcon.

the server
Fix regression in mounts to e.g. onedrive shares.
Generally, reparse points are processed by the SMB server during the
SMB OPEN request, but there are few reparse points which do not have
OPEN-like meaning for the SMB server and has to be processed by the SMB
client. Those are symlinks and special files (fifo, socket, block, char).
For Linux SMB client, it is required to process also name surrogate reparse
points as they represent another entity on the SMB server system. Linux
client will mark them as separate mount points. Examples of name surrogate
reparse points are NTFS junction points (e.g. created by the "mklink" tool
on Windows servers).
So after processing the name surrogate reparse points, clear the
-EOPNOTSUPP error code returned from the parse_reparse_point() to let SMB
server to process reparse points.
And remove printing misleading error message "unhandled reparse tag:" as
reparse points are handled by SMB server and hence unhandled fact is normal
operation.

When we're polling for responses and get a response that corresponds to
another request, we save the RX data in order to drain the RX queue.
If the response for the current request is not found in the request's
iteration of the queue, or if the queue is empty, we must check whether
the RX data was saved by a previous request when it drained the RX queue.
We failed to check for already saved responses when the queue was empty,
and requests could time out. Check saved RX before bailing out on empty
RX queue.

Normally scratch page is not allowed when a vm is operate under page
fault mode, i.e., in the existing codes, DRM_XE_VM_CREATE_FLAG_SCRATCH_PAGE
and DRM_XE_VM_CREATE_FLAG_FAULT_MODE are mutual exclusive. The reason
is fault mode relies on recoverable page to work, while scratch page
can mute recoverable page fault.
On xe2 and xe3, out of bound prefetch can cause page fault and further
system hang because xekmd can't resolve such page fault. SYCL and OCL
language runtime requires out of bound prefetch to be silently dropped
without causing any functional problem, thus the existing behavior
doesn't meet language runtime requirement.
At the same time, HW prefetching can cause page fault interrupt. Due to
page fault interrupt overhead (i.e., need Guc and KMD involved to fix
the page fault), HW prefetching can be slowed by many orders of magnitude.
Fix those problems by allowing scratch page under fault mode for xe2 and
xe3. With scratch page in place, HW prefetching could always hit scratch
page instead of causing interrupt.
A side effect is, scratch page could hide application program error.
Application out of bound accesses are hided by scratch page mapping,
instead of get reported to user.

v3: Move the scratch page flag check to after scratch page wa (Thomas)

When a vm runs under fault mode, if scratch page is enabled, we need
to clear the scratch page mapping on vm_bind for the vm_bind address
range. Under fault mode, we depend on recoverable page fault to
establish mapping in page table. If scratch page is not cleared, GPU
access of address won't cause page fault because it always hits the
existing scratch page mapping.
When vm_bind with IMMEDIATE flag, there is no need of clearing as
immediate bind can overwrite the scratch page mapping.
So far only is xe2 and xe3 products are allowed to enable scratch page
under fault mode. On other platform we don't allow scratch page under
fault mode, so no need of such clearing.
v2: Rework vm_bind pipeline to clear scratch page mapping. This is similar
to a map operation, with the exception that PTEs are cleared instead of
pointing to valid physical pages. (Matt, Thomas)

TLB. (Matt, Thomas)
