STB (Spill to DRAM) is an optional debugging facility that is only enabled
through the enable_stb module parameter. On some platforms the SMU refuses
the S2D setup outright, and on long-running systems the large telemetry
region can fail to ioremap. In either case amd_stb_s2d_init() returns an
error and, because probe treated that as fatal, the entire PMC driver
failed to load - silently disabling s0i3 support even though STB is only a
debug aid.
Downgrade the failure to a warning and continue probing so that s0i3
support via the LPS0 handler no longer depends on an optional debug
feature.
Since probe no longer aborts on this path, the LPS0 and debugfs unwinding
added by the earlier fix in this series becomes unreachable and is removed.

amd_pmc_probe() registers the LPS0 s2idle handler with
acpi_register_lps0_dev() and creates the driver's debugfs directory before
calling amd_stb_s2d_init(), which is the last step in probe that can fail.
When amd_stb_s2d_init() fails (for example the S2D telemetry region cannot
be ioremapped on a long-running system, or the SMU rejects the S2D setup)
the error path only calls pci_dev_put() and returns. This leaves
amd_pmc_s2idle_dev_ops on the global lps0_s2idle_devops_head list and leaks
the debugfs directory, while the devm-managed resources backing the handler
are torn down.
Reloading the module then walks the corrupted list in
acpi_register_lps0_dev() and hits:
list_add corruption. next->prev should be prev, but was NULL.
kernel BUG at lib/list_debug.c:29!
acpi_register_lps0_dev+0x44/0x80
amd_pmc_probe+0x224/0x380 [amd_pmc]
platform_probe+0x67/0x90
Even without a reload, the stale registration means the next s2idle
transition calls into torn-down driver state.
Unwind the debugfs directory and the LPS0 registration on the
amd_stb_s2d_init() error path. acpi_unregister_lps0_dev() is safe to call
unconditionally here: it is guarded on the same conditions as
acpi_register_lps0_dev(), which is exactly what amd_pmc_remove() already
relies on.

amd_stb_s2d_init() creates the v2 "stb_read" debugfs node before mapping
the telemetry buffer into dev->stb_virt_addr, leaving a window during probe
where a read faults on a NULL dev->stb_virt_addr in
amd_stb_debugfs_open_v2()/amd_stb_handle_efr().
This becomes trivial to hit once a failed STB init no longer aborts probe
(next patch), which leaves the node registered with a NULL buffer. Create
it only after dev->stb_virt_addr is mapped.

amd_stb_s2d_init() discards the return value of several S2D SMU commands.
When the SMU refuses a command (e.g. "SMU cmd failed. err: 0xff") the
failure is only noticed indirectly - if at all - and reported as -EIO,
masking the real error.
More seriously, the S2D_PHYS_ADDR_LOW/HIGH return values are ignored, so
on failure phys_addr_low/hi are left uninitialised and the assembled
address is passed straight to devm_ioremap(). When the SMU leaves them at
zero this maps physical address 0 and trips the ioremap-on-RAM warning:
amd_pmc AMDI000B:00: SMU cmd failed. err: 0xff
ioremap on RAM at 0x0000000000000000 - 0x0000000000ffffff
WARNING: CPU: 13 PID: 4592 at arch/x86/mm/ioremap.c:...
Check the return value of each SMU command and propagate it, and reject a
zero physical address before calling devm_ioremap().

amd_stb_debugfs_open_v2() switches dev->msg_port to MSG_PORT_S2D to query
S2D telemetry but only restores it to MSG_PORT_PMC on one path. The early
return on the dump_custom_stb path (and the error/allocation returns) leave
the port stuck on MSG_PORT_S2D, so subsequent SMU communication - including
the s2idle prepare/restore handlers - is directed at the wrong mailbox.

always restored, mirroring the fix in amd_stb_s2d_init().

The ThinkPad T14 Gen 2 AMD was sold under two machine types, 20XK and
20XL, but only 20XK has been in the s2idle quirk list since the quirk
was introduced in commit 455cd867b85b ("platform/x86: thinkpad_acpi:
Add a s2idle resume quirk for a number of laptops").
On 20XL machines the firmware SMI handler therefore still runs on the
NVMe D3->D0 transition when exiting suspend-to-idle. With IOMMU
translation enabled (the default), this intermittently stalls resume
for ~10.25 seconds: seven devices across three root ports (nvme, both
xhci_hcd functions, xhci-pci-renesas, snd_hda_intel x2, snd_rn_pci_acp3x)
block in pci_pm_resume_noirq and are released simultaneously, consistent
with all cores being held in SMM.
Add the missing 20XL machine type, mirroring the existing 20XK entry.
This is the same class of omission fixed by commit 9a469c6dfab3
("platform/x86: thinkpad_acpi: Add missing T14s Gen1 type to s2idle
quirk list").
Verified on a ThinkPad T14 Gen 2a (type 20XLS41C00, BIOS R1MET62W 1.32,
kernel 6.12.95): with this entry the quirk message appears at probe and
a 14-hour suspend resumes in ~1s with no noirq stalls, where previously
even short suspends could hit the ~10s delay. A further two-day soak
(short naps and two ~14-hour suspends) showed every resume clean.

PMFW reports the S0i3 subsystem accounting per SoC, and the set of IP
blocks and their bit ordering differ across SoC generations. Family
1Ah, Model 80h accounts for a distinct set of 19 IP blocks, which does
not match the ordering in soc15_ip_blk[].
Commit 043af31c8d30 ("platform/x86/amd/pmc: Add PMC driver support for
AMD 1Ah M80H SoC") wired amd_1ah_m80_cpu_info to soc15_ip_blk[], so

It was reported that suspend-then-hibernate stopped working with modern
systemd versions on AMD Cezanne systems. The reason for this breakage
was because systemd switched to using alarmtimer instead of the wakealarm
sysfs file.
On AMD Cezanne systems, amd_pmc_verify_czn_rtc() programs a secondary
timer with the alarm time. This was introduced by
commit 59348401ebed ("platform/x86: amd-pmc: Add special handling for
timer based S0i3 wakeup"). However, this function uses rtc_read_alarm(),
which only reads the aie_timer, not the next expiring timer from the
timerqueue.
When both alarmtimer and wakealarm are active, the first expiring timer
might be the alarmtimer, but amd_pmc_verify_czn_rtc() would only see
the aie_timer, potentially missing the earlier alarm.
Switch to rtc_read_next_alarm() to read whichever timer will fire next.
Also handle -ENOENT (no alarm pending) explicitly as a non-error case.

The ECs in the IdeaPads that need the delay_suspend quirk send lots
of messages when charging, which not only causes intermediate wakeups
when suspended, but also prevents the device from reaching the deepest
suspend state.
Because of this amd_pmc_intermediate_wakeup_need_delay() returns false
during intermediate wakeups and amd_pmc_want_suspend_delay() is called.
So far it always logged its "Delaying suspend by 2.5s ..." messages
then, which spams dmesg. This commit makes sure that those messages are
only logged once per suspend.

Enabling the new delay_suspend module parameter delays suspend for
2.5 seconds which is known to help for some AMD-based Lenovo Laptops
that otherwise failed to send/receive events for key presses or the
lid switch after s2idle. Apparently the EC needs to do some things
in the background before suspend or it gets into a bad state.
There are many reports of AMD-based laptops (mostly but not exclusively
IdeaPads) about similar issues on the web; this parameter gives
affected users an easy way to try out if their issues have the same
root cause and to work around them until their specific device is added
to the quirks list.
The parameter description has a note encouraging users to report
their device so it can be added to the quirks list, inspired by a
similar request in parameter descriptions of the ideapad-laptop module.
The module parameter can be set to "1" to explicitly enable it,
"0" to disable it even on devices that are assumed to be affected,
or -1 (the default) to enable it if the device is assumed to be affected
(according to fwbug_list[])

Some IdeaPad Slim 3 devices and similar with AMD CPUs have a
nonfunctional keyboard and lid switch after s2idle.
It helps to delay suspend by 2.5 seconds so the EC has some time
to do whatever it needs to get done before suspend - unfortunately
at least on my 16ABR8 waking it with a timer (wakealarm) still
triggers the issue, but at least normal resume via keypress or
lid works fine. On the 14ARP10 wakealarm has been reported to also
work fine with this patch.
This issue has been reported for many different devices, this patch
has been tested with the Zen3-based IdeaPad Slim 3 16ABR8 (82XR)
and the Zen3+-based IdeaPad Slim 3 14ARP10 (83K6) and IdeaPad Slim 3
15ARP10 (83MM).

boot_cpu_data.x86_model detection to distinguish the M70 sub-variant.
Add scratch_reg to amd_pmc_cpu_info and populate it for each SoC
variant, allowing amd_pmc_idlemask_read() to drop its cpu_id switch
in favour of a single cpu_info->scratch_reg lookup.
Move dev->cpu_id assignment into amd_pmc_set_cpu_info() so it is valid
before the switch statement. Handle SP/SHP directly in the switch since
their NULL driver_data bypasses the early return, and remove the duplicate
check from probe.
Remove amd_pmc_get_os_hint() and use cpu_info->os_hint directly at call
sites and rename AMD_CPU_ID_* to PCI_DEVICE_ID_AMD_CPU_ID_* with backward
compatibility aliases.

This is the exact same thing as the 'alloc_obj()' version, only much
smaller because there are a lot fewer users of the *alloc_flex()

As with alloc_obj() version, this was done entirely with mindless brute

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)
(where TYPE may also be *VAR)
The resulting allocations no longer return "void *", instead returning
"TYPE *".

atkbd serio0: Spurious ACK on isa0060/serio0. Some program might be trying to access hardware directly.

The ROG Xbox Ally (non-X) SoC features a similar architecture to the
Steam Deck. While the Steam Deck supports S3 (s2idle causes a crash),
this support was dropped by the Xbox Ally which only S0ix suspend.
Since the handler is missing here, this causes the device to not suspend
and the AMD GPU driver to crash while trying to resume afterwards due to
a power hang.

Chris reported that even on a BIOS that has a new enough SMU F/W
version there is still a spurious IRQ1. Although the solution was
added to SMU F/W 64.66.0 it turns out there needs to be a matching
SBIOS change to activate it. Thus Linux shouldn't be avoiding the
IRQ1 workaround on newer SMU F/W because there is no indication the
BIOS change is in place.
Drop the match for 64.66.0+ and instead match all RN/CZN/BRC (they
all share same SMU F/W). Adjust the quirk infrastructure to allow
quirking the workaround on or off and also adjust existing quirks
to match properly.
Unfortunately this may cause some systems that did have the SBIOS
change in place to regress in keyboard wakeup but we don't have a
way to know. If a user reports a keyboard wakeup regression they can
run with amd_pmc.disable_workarounds=1 to deactivate the workaround
and share DMI data so that their system can be quirked not to use
the workaround in the upstream kernel.

The area of memory that contains the metrics table may contain garbage
when the cycle starts. This normally doesn't matter because the cycle
itself will populate it with valid data, however commit 9f5595d5f03fd
("platform/x86/amd: pmc: Require at least 2.5 seconds between HW sleep
cycles") started to use it during the check() phase. Depending upon
what garbage is in the table it's possible that the system will wait
2.5 seconds for even the first cycle, which will be visible to a user.
To prevent this from happening explicitly clear the table when logging
is started.

MECHREVO Wujie 14XA (GX4HRXL) wakes up immediately after s2idle entry.
This happens regardless of whether the laptop is plugged into AC power,
or whether any peripheral is plugged into the laptop.
Similar to commit a55bdad5dfd1 ("platform/x86/amd/pmc: Disable keyboard
wakeup on AMD Framework 13"), the MECHREVO Wujie 14XA wakes up almost
instantly after s2idle suspend entry (IRQ1 is the keyboard):
2025-04-18 17:23:57,588 DEBUG: PM: Triggering wakeup from IRQ 9
2025-04-18 17:23:57,588 DEBUG: PM: Triggering wakeup from IRQ 1
Add this model to the spurious_8042 quirk to workaround this.
This patch does not affect the wake-up function of the built-in keyboard.
Because the firmware of this machine adds an insurance for keyboard
wake-up events, as it always triggers an additional IRQ 9 to wake up the
system.

When an APU exits HW sleep with no active wake sources the Linux kernel will
rapidly assert that the APU can enter back into HW sleep. This happens in a
few ms. Contrasting this to Windows, Windows can take 10s of seconds to
enter back into the resiliency phase for Modern Standby.
For some situations this can be problematic because it can cause leakage
from VDDCR_SOC to VDD_MISC and force VDD_MISC outside of the electrical
design guide specifications. On some designs this will trip the over
voltage protection feature (OVP) of the voltage regulator module, but it
could cause APU damage as well.
To prevent this risk, add an explicit sleep call so that future attempts
to enter into HW sleep will have enough time to settle. This will occur
while the screen is dark and only on cases that the APU should enter HW
sleep again, so it shouldn't be noticeable to any user.

Pull misc x86 updates from Borislav Petkov:
- The first part of a restructuring of AMD's representation of a
northbridge which is legacy now, and the creation of the new AMD node
concept which represents the Zen architecture of having a collection
of I/O devices within an SoC. Those nodes comprise the so-called data
fabric on Zen.
This has at least one practical advantage of not having to add a PCI
ID each time a new data fabric PCI device releases. Eventually, the
lot more uniform provider of data fabric functionality amd_node.c
will be used by all the drivers which need it
- Smaller cleanups
