The fw_attributes_class provides a much cleaner interface to all of the attributes introduced to asus-wmi. This patch moves all of these extra attributes over to fw_attributes_class, and shifts the bulk of these definitions to a new kernel module to reduce the clutter of asus-wmi with the intention of deprecating the asus-wmi attributes in future. The work applies only to WMI methods which don't have a clearly defined place within the sysfs and as a result ended up lumped together in /sys/devices/platform/asus-nb-wmi/ with no standard API. Where possible the fw attrs now implement defaults, min, max, scalar, choices, etc. As en example dgpu_disable becomes: /sys/class/firmware-attributes/asus-armoury/attributes/dgpu_disable/ ├── current_value ├── display_name ├── possible_values └── type as do other attributes.

The recent regression report revealed that the use of WC pages for AMD HDMI device together with AMD IOMMU leads to unexpected truncation or noises. The issue seems triggered by the change in the kernel core memory allocation that enables IOMMU driver to use always S/G buffers. Meanwhile, the use of WC pages has been a workaround for the similar issue with standard pages in the past. So, now we need to apply the workaround conditionally, namely, only when IOMMU isn't in place. This patch modifies the workaround code to check the DMA ops at first and apply the snoop-off only when needed.

All the _DSM methods for the LPS0 method are called back to back currently. The intended use of the screen off and screen on calls is supposed to be matching the screen being turned on or off though. Add support for other parts of the kernel to call such a callback. Signed-off-by: Mario Limonciello <mario.limonciello@amd.com>

Normally systems don't wake up from s2idle when the AC adapter has changed, but users or other drivers may have a desire to configure this behavior. Add the ability for the LPS0 device to wake the system when AC adapter changes. Also add a new member to `struct acpi_s2idle_dev_ops` to let drivers indicate the system should wakeup by default from AC adapter changes. Signed-off-by: Mario Limonciello <mario.limonciello@amd.com>
This driver adds full support of the ASUS ROG Ally gamepad:
- dinput is translated to XBox controller (Ally-X only)
- default mode has the QAM buttons mapped (Ally-X only)
* left is XBox button
* right is an XBox + A combo for steam QAM
- force feedback is supported (Ally-X only)
- LED brightness control (0-2)
- LED multicolor class support for all 4 LED, individually addressable
- Support all configuration
Where "Ally-X only" is mentioned, this is because the Ally 1 uses the
existing xpad driver.
The configuration options available are:
- Gamepad mode (game, wasd, mouse)
- Remapping each button, plus macro map (hold a macro button and press other)
- Joystrick and trigger deadzones
- Gamepad vibration intensity
- Leds (using multicolor class)
- Button turbo abilities (per button)
- Joystick repsonse curves
- Joystick anti-deadzones
The attribute path tree looks like this:
- `./sys/../<USB HID>/`
- `joystick_left/
- `deadzone`
- `mapping` (mouse, wasd, custom)
- `anti_deadzone`
- `response_curve`
- `calibration`
- `calibration_reset`
- `trigger_left/
- `deadzone`
- `response_curve`
- `calibration`
- `calibration_reset`
- `gamepad_mode`
- `button_mapping`
- `A`
- `B`
- `dpad_left`
- etc
No settings are applied until `apply_all` is written to. The exception is
for calibrations.
While there is calibration ability, it can be difficult to get correct
and is heavily device dependent, as such it is set when written and not
when `apply_all` is written to. On driver load the set calibrations are
retrieved - this may be what you've set in Linux, Windows, or factory
defaults.
As a note: the proper way to set calibrations is to read the joystick
voltage from the EC whcih currently is not possible.

When PG_hwpoison pages are freed they are treated differently in free_pages_prepare() and instead of being released they are isolated. Page allocation tag counters are decremented at this point since the page is considered not in use. Later on when such pages are released by unpoison_memory(), the allocation tag counters will be decremented again and the following warning gets reported: [ 113.930443][ T3282] ------------[ cut here ]------------ [ 113.931105][ T3282] alloc_tag was not set [ 113.931576][ T3282] WARNING: CPU: 2 PID: 3282 at ./include/linux/alloc_tag.h:130 pgalloc_tag_sub.part.66+0x154/0x164 [ 113.932866][ T3282] Modules linked in: hwpoison_inject fuse ip6t_rpfilter ip6t_REJECT nf_reject_ipv6 ipt_REJECT nf_reject_ipv4 xt_conntrack ebtable_nat ebtable_broute ip6table_nat ip6table_man4 [ 113.941638][ T3282] CPU: 2 UID: 0 PID: 3282 Comm: madvise11 Kdump: loaded Tainted: G W 6.11.0-rc4-dirty ChimeraOS#18 [ 113.943003][ T3282] Tainted: [W]=WARN [ 113.943453][ T3282] Hardware name: QEMU KVM Virtual Machine, BIOS unknown 2/2/2022 [ 113.944378][ T3282] pstate: 40400005 (nZcv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) [ 113.945319][ T3282] pc : pgalloc_tag_sub.part.66+0x154/0x164 [ 113.946016][ T3282] lr : pgalloc_tag_sub.part.66+0x154/0x164 [ 113.946706][ T3282] sp : ffff800087093a10 [ 113.947197][ T3282] x29: ffff800087093a10 x28: ffff0000d7a9d400 x27: ffff80008249f0a0 [ 113.948165][ T3282] x26: 0000000000000000 x25: ffff80008249f2b0 x24: 0000000000000000 [ 113.949134][ T3282] x23: 0000000000000001 x22: 0000000000000001 x21: 0000000000000000 [ 113.950597][ T3282] x20: ffff0000c08fcad8 x19: ffff80008251e000 x18: ffffffffffffffff [ 113.952207][ T3282] x17: 0000000000000000 x16: 0000000000000000 x15: ffff800081746210 [ 113.953161][ T3282] x14: 0000000000000000 x13: 205d323832335420 x12: 5b5d353031313339 [ 113.954120][ T3282] x11: ffff800087093500 x10: 000000000000005d x9 : 00000000ffffffd0 [ 113.955078][ T3282] x8 : 7f7f7f7f7f7f7f7f x7 : ffff80008236ba90 x6 : c0000000ffff7fff [ 113.956036][ T3282] x5 : ffff000b34bf4dc8 x4 : ffff8000820aba90 x3 : 0000000000000001 [ 113.956994][ T3282] x2 : ffff800ab320f000 x1 : 841d1e35ac932e00 x0 : 0000000000000000 [ 113.957962][ T3282] Call trace: [ 113.958350][ T3282] pgalloc_tag_sub.part.66+0x154/0x164 [ 113.959000][ T3282] pgalloc_tag_sub+0x14/0x1c [ 113.959539][ T3282] free_unref_page+0xf4/0x4b8 [ 113.960096][ T3282] __folio_put+0xd4/0x120 [ 113.960614][ T3282] folio_put+0x24/0x50 [ 113.961103][ T3282] unpoison_memory+0x4f0/0x5b0 [ 113.961678][ T3282] hwpoison_unpoison+0x30/0x48 [hwpoison_inject] [ 113.962436][ T3282] simple_attr_write_xsigned.isra.34+0xec/0x1cc [ 113.963183][ T3282] simple_attr_write+0x38/0x48 [ 113.963750][ T3282] debugfs_attr_write+0x54/0x80 [ 113.964330][ T3282] full_proxy_write+0x68/0x98 [ 113.964880][ T3282] vfs_write+0xdc/0x4d0 [ 113.965372][ T3282] ksys_write+0x78/0x100 [ 113.965875][ T3282] __arm64_sys_write+0x24/0x30 [ 113.966440][ T3282] invoke_syscall+0x7c/0x104 [ 113.966984][ T3282] el0_svc_common.constprop.1+0x88/0x104 [ 113.967652][ T3282] do_el0_svc+0x2c/0x38 [ 113.968893][ T3282] el0_svc+0x3c/0x1b8 [ 113.969379][ T3282] el0t_64_sync_handler+0x98/0xbc [ 113.969980][ T3282] el0t_64_sync+0x19c/0x1a0 [ 113.970511][ T3282] ---[ end trace 0000000000000000 ]--- To fix this, clear the page tag reference after the page got isolated and accounted for.

[ Upstream commit c145eea ] mwifiex_get_priv_by_id() returns the priv pointer corresponding to the bss_num and bss_type, but without checking if the priv is actually currently in use. Unused priv pointers do not have a wiphy attached to them which can lead to NULL pointer dereferences further down the callstack. Fix this by returning only used priv pointers which have priv->bss_mode set to something else than NL80211_IFTYPE_UNSPECIFIED. Said NULL pointer dereference happened when an Accesspoint was started with wpa_supplicant -i mlan0 with this config: network={ ssid="somessid" mode=2 frequency=2412 key_mgmt=WPA-PSK WPA-PSK-SHA256 proto=RSN group=CCMP pairwise=CCMP psk="12345678" } When waiting for the AP to be established, interrupting wpa_supplicant with <ctrl-c> and starting it again this happens: | Unable to handle kernel NULL pointer dereference at virtual address 0000000000000140 | Mem abort info: | ESR = 0x0000000096000004 | EC = 0x25: DABT (current EL), IL = 32 bits | SET = 0, FnV = 0 | EA = 0, S1PTW = 0 | FSC = 0x04: level 0 translation fault | Data abort info: | ISV = 0, ISS = 0x00000004, ISS2 = 0x00000000 | CM = 0, WnR = 0, TnD = 0, TagAccess = 0 | GCS = 0, Overlay = 0, DirtyBit = 0, Xs = 0 | user pgtable: 4k pages, 48-bit VAs, pgdp=0000000046d96000 | [0000000000000140] pgd=0000000000000000, p4d=0000000000000000 | Internal error: Oops: 0000000096000004 [#1] PREEMPT SMP | Modules linked in: caam_jr caamhash_desc spidev caamalg_desc crypto_engine authenc libdes mwifiex_sdio +mwifiex crct10dif_ce cdc_acm onboard_usb_hub fsl_imx8_ddr_perf imx8m_ddrc rtc_ds1307 lm75 rtc_snvs +imx_sdma caam imx8mm_thermal spi_imx error imx_cpufreq_dt fuse ip_tables x_tables ipv6 | CPU: 0 PID: 8 Comm: kworker/0:1 Not tainted 6.9.0-00007-g937242013fce-dirty ChimeraOS#18 | Hardware name: somemachine (DT) | Workqueue: events sdio_irq_work | pstate: 00000005 (nzcv daif -PAN -UAO -TCO -DIT -SSBS BTYPE=--) | pc : mwifiex_get_cfp+0xd8/0x15c [mwifiex] | lr : mwifiex_get_cfp+0x34/0x15c [mwifiex] | sp : ffff8000818b3a70 | x29: ffff8000818b3a70 x28: ffff000006bfd8a5 x27: 0000000000000004 | x26: 000000000000002c x25: 0000000000001511 x24: 0000000002e86bc9 | x23: ffff000006bfd996 x22: 0000000000000004 x21: ffff000007bec000 | x20: 000000000000002c x19: 0000000000000000 x18: 0000000000000000 | x17: 000000040044ffff x16: 00500072b5503510 x15: ccc283740681e517 | x14: 0201000101006d15 x13: 0000000002e8ff43 x12: 002c01000000ffb1 | x11: 0100000000000000 x10: 02e8ff43002c0100 x9 : 0000ffb100100157 | x8 : ffff000003d20000 x7 : 00000000000002f1 x6 : 00000000ffffe124 | x5 : 0000000000000001 x4 : 0000000000000003 x3 : 0000000000000000 | x2 : 0000000000000000 x1 : 0001000000011001 x0 : 0000000000000000 | Call trace: | mwifiex_get_cfp+0xd8/0x15c [mwifiex] | mwifiex_parse_single_response_buf+0x1d0/0x504 [mwifiex] | mwifiex_handle_event_ext_scan_report+0x19c/0x2f8 [mwifiex] | mwifiex_process_sta_event+0x298/0xf0c [mwifiex] | mwifiex_process_event+0x110/0x238 [mwifiex] | mwifiex_main_process+0x428/0xa44 [mwifiex] | mwifiex_sdio_interrupt+0x64/0x12c [mwifiex_sdio] | process_sdio_pending_irqs+0x64/0x1b8 | sdio_irq_work+0x4c/0x7c | process_one_work+0x148/0x2a0 | worker_thread+0x2fc/0x40c | kthread+0x110/0x114 | ret_from_fork+0x10/0x20 | Code: a94153f3 a8c37bfd d50323bf d65f03c0 (f940a000) | ---[ end trace 0000000000000000 ]--- Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Acked-by: Brian Norris <briannorris@chromium.org> Reviewed-by: Francesco Dolcini <francesco.dolcini@toradex.com> Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://patch.msgid.link/20240703072409.556618-1-s.hauer@pengutronix.de Signed-off-by: Sasha Levin <sashal@kernel.org>

This is a mess because I've had to drop and cherry-pick stuff. The better way to update this would be
reset --hardon mine.
