On the THUNDEROBOT ZERO laptop, the second NVMe slot and the discrete
NVIDIA GPU are both controlled by power-resource PXP. Due to the SSDT table
bug (lack of reference), PXP will be shut dow as an "unused" power resource
during initialization, making the NVMe slot #2 + NVIDIA both inaccessible.
This issue was introduced by commit a1224f34d72a ("ACPI: PM: Check
states of power resources during initialization"). Here are test
results on the three consecutive commits:
(bad again!) a1224f34d72a ACPI: PM: Check states of power resources during initialization
(good) bc2836859643 ACPI: PM: Do not turn off power resources in unknown state
(bad) 519d81956ee2 Linux 5.15-rc6
On commit bc2836859643 ("ACPI: PM: Do not turn off power resources in
unknown state") this was not an issue because the power resource state
left UNKNOWN thus being ignored.
See also commit 9b04d99788cf ("ACPI: PM: Do not turn of unused power
resources on the Toshiba Click Mini") which is another almost identical
case to this one.
Fixes: a1224f34d72a ("ACPI: PM: Check states of power resources during initialization")

Pull clk updates from Stephen Boyd:
"Not much changed in the clk framework this time except the clk.h
consumer API moved the context saving APIs around to fix a build error
in certain configurations.
There was a change to the core framework for CLK_OPS_PARENT_ENABLE
behavior during registration, but it wrecked existing drivers that
didn't expect things to be turned off during clk registration so it
got reverted.
This cycle is really a large collection of new clk drivers, primarily
for Qualcomm SoCs but also for Amlogic, SpacemiT, Google, and Aspeed.
Another big change in here is support for automatic hardware clock
gating on Samsung SoCs where the clks turn on and off when needed.
Ideally more vendors move to this method for better power savings. The
highlights are in the updates section below.
Beyond all the new drivers we have a bunch of cleanups like converting
drivers from divider_round_rate() to divider_determine_rate() and
using scoped for each OF child loops. Otherwise it's the usual data
fixes and plugging reference leaks, etc. that's all pretty ordinary
but not critical enough to fix until the next release.
New Drivers:
- Qualcomm Kaanapali global, tcsr, rpmh, display, gpu, camera, and
video clk controllers
- Qualcomm SM8750 camera clk controllers
- Qualcomm MSM8940 and SDM439 global clk controllers
- Google GS101 Display Process Unit (DPU) clk controllers
- SpacemiT K3 clk controllers
- Amlogic t7 clk controllers
- Aspeed AST2700 clk controllers
Updates:
- Convert clock dividers from round_rate() to determine_rate()
- Fix sparse warnings, kernel-doc warnings, and plug leaked OF refs
- Automatic hardware clk gating on Google GS101 SoCs
- Amlogic s4 video clks
- CAN-FD clks and resets on Renesas RZ/T2H, RZ/N2H, RZ/V2H, and
RZ/V2N
- Expanded Serial Peripheral Interface (xSPI) clocks and resets on
Renesas RZ/T21H and RZ/N2H
- DMAC, interrupt controller (ICU), SPI, and thermal (TSU) clocks and
resets on Renesas RZ/V2N
- More serial (RSCI) clocks and resets on Renesas RZ/V2H and RZ/V2N
- CPU frequency scaling on T-HEAD TH1520"

When CONFIG_FB_DEVICE is disabled, struct fb_info does
not provide a valid dev pointer. Direct dereferences of
fb_info->dev therefore result in build failures.
Fix this by avoiding direct accesses to fb_info->dev and

that do not rely on a device pointer.

do_con_write(), fbcon_redraw.*() invoke console_conditional_schedule()
which is a conditional scheduling point based on printk's internal
variables console_may_schedule. It may only be used if the console lock
is acquired for instance via console_lock() or console_trylock().
Prinkt sets the internal variable to 1 (and allows to schedule)
if the console lock has been acquired via console_lock(). The trylock
does not allow it.
The console_conditional_schedule() invocation in do_con_write() is
invoked shortly before console_unlock().
The console_conditional_schedule() invocation in fbcon_redraw.*()
original from fbcon_scroll() / vt's con_scroll() which originate from a
line feed.
In console_unlock() the variable is set to 0 (forbids to schedule) and
it tries to schedule while making progress printing. This is brand new
compared to when console_conditional_schedule() was added in v2.4.9.11.
In v2.6.38-rc3, console_unlock() (started its existence) iterated over
all consoles and flushed them with disabled interrupts. A scheduling
attempt here was not possible, it relied that a long print scheduled
before console_unlock().
Since commit 8d91f8b15361d ("printk: do cond_resched() between lines
while outputting to consoles"), which appeared in v4.5-rc1,
console_unlock() attempts to schedule if it was allowed to schedule
while during console_lock(). Each record is idealy one line so after
every line feed.
This console_conditional_schedule() is also only relevant on
PREEMPT_NONE and PREEMPT_VOLUNTARY builds. In other configurations
cond_resched() becomes a nop and has no impact.
I'm bringing this all up just proof that it is not required anymore. It
becomes a problem on a PREEMPT_RT build with debug code enabled because
that might_sleep() in cond_resched() remains and triggers a warnings.
This is due to
legacy_kthread_func-> console_flush_one_record -> vt_console_print-> lf
-> con_scroll -> fbcon_scroll
and vt_console_print() acquires a spinlock_t which does not allow a
voluntary schedule. There is no need to fb_scroll() to schedule since
console_flush_one_record() attempts to schedule after each line.
!PREEMPT_RT is not affected because the legacy printing thread is only
enabled on PREEMPT_RT builds.
Therefore I suggest to remove console_conditional_schedule().

of_parse_phandle() returns a device_node with refcount incremented,
which is stored in 'entry' and then copied to 'native_mode'. When the
error paths at lines 184 or 192 jump to 'entryfail', native_mode's
refcount is not decremented, causing a refcount leak.

Now that the path to the logo file can be directly entered in Kbuild,
there is no more need to handle all the logo file selection in the
Makefile and the C files.
The only exception is the logo_spe_clut224 which is only used by the
Cell processor (found for example in the Playstation 3) [1]. This
extra logo uses its own different image which shows up on a separate
line just below the normal logo. Because the extra logo uses a
different image, it can not be factorized under the custom logo logic.
Move all the logo file selection logic to Kbuild (except from the
logo_spe_clut224.ppm), this done, clean-up the C code to only leave
one entry for each logo type (monochrome, 16-colors and 224-colors).

The logo_mac_clut224 depends on the runtime value MACH_IS_MAC being
true to be displayed. This makes that logo a one-of-a-kind, as it is
the only one whose selection can not be decided at compile time.
This dynamic logo selection logic conflicts with our upcoming plans to
simplify the logo selection code.
Considering that the logo_mac_clut224 is only used by the Macintosh
68k, a machine whose sales ended some thirty years ago and which thus
represents a very small user base, it is preferable to resolve the
conflict in favour of code simplicity.
Remove the logo_mac_clut224 so that the logo selection can be
statically determined at compile time.
The users who wish to continue using that logo can still download it
from [1] and add:
CONFIG_LOGO_LINUX_CLUT224=y
CONFIG_LOGO_LINUX_CLUT224_FILE="/path/to/logo_mac_clut224.ppm"
to their configuration file to restore it.

Some people like to replace the default Tux boot logo by an image of
their own. There exist a few tutorials here [1] and there [2]. But
this requires modifying the source tree which is a bit cumbersome.
Add a string entry in Kbuild for each of the logo categories
(monochrome, 16-colors, 224-colors). The string entry takes a path to
a .pbm or .ppm image allowing the user to more easily provide a custom
logo without having to modify the sources.
Add an help entry with a short hint on how to convert images to the
portable pixmap file format.
Update the Makefile accordingly. When converted to .c file, the logo
will have one of these fixed file name:
- logo_linux_mono.c
- logo_linux_vga16.c
- logo_linux_clut224.c:
depending on the image type and this regardless of the name of the
.pgm/.ppm source filename. This will allow for further simplifications
in an upcoming change.

When translating a portable pixmap file into a .c file, the pnmtologo
tool expects to receive the image type (either mono, vga16 or clut224)
as an argument under the -t option.
Currently, this information is stored in the file name. Because we
will allow for custom logo in an upcoming change, it is preferable to
decouple the image name from its type.
Add a new $2 parameter to the Makefile logo function which contains
the image type.
Update all the individual targets to provide this new argument.

The fbdev sysfs attributes are registered after sending the uevent for
the device creation, leaving a race window where e.g. udev rules may
not be able to access the sysfs attributes because the registration is
not done yet.
Fix this by switching to device_create_with_groups(). This also results in
a nice cleanup. After switching to device_create_with_groups() all that
is left of fb_init_device() is setting the drvdata and that can be passed
to device_create[_with_groups]() too. After which fb_init_device() can
be completely removed.
Dropping fb_init_device() + fb_cleanup_device() in turn allows removing
fb_info.class_flag as they were the only user of this field.

A userspace program can trigger the RIVA NV3 arbitration code by calling
the FBIOPUT_VSCREENINFO ioctl on /dev/fb*. When doing so, the driver
recomputes FIFO arbitration parameters in nv3_arb(), using state->mclk_khz
(derived from the PRAMDAC MCLK PLL) as a divisor without validating it
first.
In a normal setup, state->mclk_khz is provided by the real hardware and is
non-zero. However, an attacker can construct a malicious or misconfigured
device (e.g. a crafted/emulated PCI device) that exposes a bogus PLL
configuration, causing state->mclk_khz to become zero. Once
nv3_get_param() calls nv3_arb(), the division by state->mclk_khz in the gns
calculation causes a divide error and crashes the kernel.
Fix this by checking whether state->mclk_khz is zero and bailing out before
doing the division.

It is not necessary to clear the driver_data pointer in the ACPI
companion device object on driver remove in the EC and SMBUS HC
ACPI drivers because that pointer is not used there any more after
recent changes.
Drop the unnecessary statements.

After commit 02c057ddefef ("ACPI: video: Convert the driver to a
platform one") the driver_data pointer in the ACPI companion device
object is not cleared automatically on driver remove any more, so
clear it directly in acpi_video_bus_remove().

Fixes a theoretical race on fw_log between the teardown path and fw_log
write functions.
fw_log is written inside fbnic_fw_log_write() and can be reached from
the mailbox handler fbnic_fw_msix_intr(), but fw_log is freed before
IRQ/MBX teardown during cleanup, resulting in a potential data race of
dereferencing a freed/null variable.
Possible Interleaving Scenario:
CPU0: fbnic_fw_msix_intr() // Entry
fbnic_fw_log_write()
if (fbnic_fw_log_ready()) // true
... preempt ...
CPU1: fbnic_remove() // Entry
fbnic_fw_log_free()
vfree(log->data_start);
log->data_start = NULL;
CPU0: continues, walks log->entries or writes to log->data_start
The initialization also has an incorrect order problem, as the fw_log
is currently allocated after MBX setup during initialization.
Fix the problems by adjusting the synchronization order to put
initialization in place before the mailbox is enabled, and not cleared
until after the mailbox has been disabled.

The max_adj field in ptp_clock_info tells userspace how much the PHC
clock frequency can be adjusted. ptp4l reads this and will never request
a correction larger than max_adj.
On both sparx5 and lan969x the clock offset may never converge because
the servo needs a frequency correction larger than the current max_adj
of 200000 (200 ppm) allows. The servo rails at the max and the offset
stays in the tens of microseconds.
The hardware has no inherent max adjustment limit; frequency correction
is done by writing a 64-bit clock period increment to CLK_PER_CFG, and
the register has plenty of range. The 200000 value was just an overly
conservative software limit. The max_adj is shared between sparx5 and
lan969x, and the increased value is safe for both.
Fix this by increasing max_adj to 10000000 (10000 ppm), giving the
servo sufficient headroom.
