HID: amd_sfh: Validate PCI BAR size before mapping
The amd_sfh driver maps PCI BAR 2 using pcim_iomap_regions() and
subsequently accesses MMIO registers at offsets up to 0x10958 (e.g.,
AMD_P2C_MSG3 at 0x1068C). However, the driver never validates that the BAR
size is large enough to cover these accesses. If the driver is bound to a
device with a smaller BAR 2, this leads to an out-of-bounds memory access
and a page fault during the probe function.
For example, a page fault can occur when reading from privdata->mmio +
AMD_P2C_MSG3 in mp2_select_ops():
BUG: unable to handle page fault for address: ffffc9000390368c
PGD 100000067 P4D 100000067 PUD 1012c1067 PMD 105b64067 PTE 0

Fix this by verifying that the length of BAR 2 is at least 128KB before
attempting to map it. Since the maximum accessed offset is 0x10958, and PCI
BAR sizes are powers of 2, any legitimate hardware will have a BAR size of
at least 128KB.

HID: amd_sfh: Serialize access to the shared emp2 pointer
The SFH accessors reach the device through a file-global emp2 pointer that is published at probe and cleared on remove. amd_get_sfh_info() is exported and called from other modules on unrelated threads, so a reader can observe a non-NULL emp2 and then race a concurrent unbind that clears it and frees the device. Serialize the emp2 publish/clear and all readers under a mutex, so a reader either sees a live device for the whole access or sees NULL.

HID: amd_sfh: Track MP2 version explicitly
The MP2 version is currently known only implicitly, from whether an ops pointer was stored in the PCI driver_data. Subsequent changes need to act on the MP2 version directly, for example to read the operating-mode register only on confirmed MP2 v2. Track the MP2 version explicitly so that version-specific behaviour can be gated on it, and leave it unset for generations that do not require such handling.

HID: amd_sfh: clear hid_sensor_hubs entry on probe failure
In amdtp_hid_probe(), the newly allocated HID device is stored in cli_data->hid_sensor_hubs[cur_hid_dev] before calling hid_add_device(). If hid_add_device() fails, the error path frees the HID device and its driver_data but does not clear the array entry, leaving a dangling pointer. When the caller (amd_sfh_hid_client_init or amd_sfh1_1_hid_client_init) detects the probe failure, it jumps to its cleanup label, which unconditionally calls amd_sfh_hid_client_deinit() and subsequently amdtp_hid_remove(). The latter iterates over all hid_sensor_hubs[] entries and, upon encountering the non-NULL but freed pointer, performs a use-after-free read followed by double-free of both the HID device and its driver_data. Clear the array entry in the error path of amdtp_hid_probe() so that amdtp_hid_remove() skips the failed entry.

Also, remove the initialization of the first enum member, since it is not needed.

HID: amd_sfh: don't log error when device discovery fails with -EOPNOTSUPP
When sensor discovery fails on systems without AMD SFH sensors, the
code already emits a warning via dev_warn() in amd_sfh_hid_client_init().
The subsequent dev_err() in sfh_init_work() for the same -EOPNOTSUPP
return value is redundant and causes unnecessary alarm.
Suppress the dev_err() for -EOPNOTSUPP to avoid confusing users who
have no AMD SFH sensors.

Convert 'alloc_obj' family to use the new default GFP_KERNEL argument
This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types
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 *". Signed-off-by: Kees Cook <kees@kernel.org> |

HID: amd_sfh: Fix SRA sensor when it's the only sensor
On systems that only have an SRA sensor connected to SFH the sensor
doesn't get enabled due to a bad optimization condition of breaking
the sensor walk loop.
This optimization is unnecessary in the first place because if there
is only one device then the loop only runs once. Drop the condition
and explicitly mark sensor as enabled.

HID: amd_sfh: Default to HPD disabled
Unless you know to look for it, HPD is a surprising behavior; particularly because it can wake the system from suspend. It also has implications for power consumption because sensors are left enabled. After the sensors have been probed (and HPD is found present), explicitly turn off HPD by default.

HID: intel-thc: fix CONFIG_HID dependency
In drivers/hid/, most drivers depend on CONFIG_HID, while a couple of the
drivers in subdirectories instead depend on CONFIG_HID_SUPPORT and use
'select HID'. With the newly added INTEL_THC_HID, this causes a build
warning for a circular dependency:
WARNING: unmet direct dependencies detected for HID
Depends on [m]: HID_SUPPORT [=y] && INPUT [=m]
Selected by [y]:
- INTEL_THC_HID [=y] && HID_SUPPORT [=y] && X86_64 [=y] && PCI [=y] && ACPI [=y]

- PANTHERLORD_FF [=y] && HID_SUPPORT [=y] && HID [=y] && HID_PANTHERLORD [=m]
It's better to be consistent and always use 'depends on HID' for HID
drivers. The notable exception here is USB_KBD/USB_MOUSE, which are
alternative implementations that do not depend on the HID subsystem.
Do this by extending the "if HID" section below, which means that a few
of the duplicate "depends on HID" and "depends on INPUT" statements
can be removed in the process.

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Batch sizing of multiple BARs while memory decoding is disabled
instead of disabling/enabling decoding for each BAR individually;
this optimizes virtualized environments where toggling decoding
enable is expensive (Alex Williamson)
- Add host bridge .enable_device() and .disable_device() hooks for
bridges that need to configure things like Requester ID to StreamID
mapping when enabling devices (Frank Li)
- Extend struct pci_ecam_ops with .enable_device() and
.disable_device() hooks so drivers that use pci_host_common_probe()
instead of their own .probe() have a way to set the
.enable_device() callbacks (Marc Zyngier)
- Drop 'No bus range found' message so we don't complain when DTs
don't specify the default 'bus-range = <0x00 0xff>' (Bjorn Helgaas)
- Rename the drivers/pci/of_property.c struct of_pci_range to
of_pci_range_entry to avoid confusion with the global of_pci_range
in include/linux/of_address.h (Bjorn Helgaas)
Driver binding:
- Update resource request API documentation to encourage callers to
supply a driver name when requesting resources (Philipp Stanner)
- Export pci_intx_unmanaged() and pcim_intx() (always managed) so
callers of pci_intx() (which is sometimes managed) can explicitly
choose the one they need (Philipp Stanner)
- Convert drivers from pci_intx() to always-managed pcim_intx() or
never-managed pci_intx_unmanaged(): amd_sfh, ata (ahci, ata_piix,
pata_rdc, sata_sil24, sata_sis, sata_uli, sata_vsc), bnx2x, bna,
ntb, qtnfmac, rtsx, tifm_7xx1, vfio, xen-pciback (Philipp Stanner)
- Remove pci_intx_unmanaged() since pci_intx() is now always
unmanaged and pcim_intx() is always managed (Philipp Stanner)
Error handling:
- Unexport pcie_read_tlp_log() to encourage drivers to use PCI core
logging rather than building their own (Ilpo Järvinen)
- Move TLP Log handling to its own file (Ilpo Järvinen)
- Store number of supported End-End TLP Prefixes always so we can
read the correct number of DWORDs from the TLP Prefix Log (Ilpo
Järvinen)
- Read TLP Prefixes in addition to the Header Log in
pcie_read_tlp_log() (Ilpo Järvinen)
- Add pcie_print_tlp_log() to consolidate printing of TLP Header and
Prefix Log (Ilpo Järvinen)
- Quirk the Intel Raptor Lake-P PIO log size to accommodate vendor
BIOSes that don't configure it correctly (Takashi Iwai)
ASPM:
- Save parent L1 PM Substates config so when we restore it along with
an endpoint's config, the parent info isn't junk (Jian-Hong Pan)
Power management:
- Avoid D3 for Root Ports on TUXEDO Sirius Gen1 with old BIOS because
the system can't wake up from suspend (Werner Sembach)
Endpoint framework:
- Destroy the EPC device in devm_pci_epc_destroy(), which previously
didn't call devres_release() (Zijun Hu)
- Finish virtual EP removal in pci_epf_remove_vepf(), which
previously caused a subsequent pci_epf_add_vepf() to fail with
-EBUSY (Zijun Hu)
- Write BAR_MASK before iATU registers in pci_epc_set_bar() so we
don't depend on the BAR_MASK reset value being larger than the
requested BAR size (Niklas Cassel)
- Prevent changing BAR size/flags in pci_epc_set_bar() to prevent
reads from bypassing the iATU if we reduced the BAR size (Niklas
Cassel)
- Verify address alignment when programming iATU so we don't attempt
to write bits that are read-only because of the BAR size, which
could lead to directing accesses to the wrong address (Niklas
Cassel)
- Implement artpec6 pci_epc_features so we can rely on all drivers
supporting it so we can use it in EPC core code (Niklas Cassel)
- Check for BARs of fixed size to prevent endpoint drivers from
trying to change their size (Niklas Cassel)
- Verify that requested BAR size is a power of two when endpoint
driver sets the BAR (Niklas Cassel)
Endpoint framework tests:
- Clear pci-epf-test dma_chan_rx, not dma_chan_tx, after freeing
dma_chan_rx (Mohamed Khalfella)
- Correct the DMA MEMCPY test so it doesn't fail if the Endpoint
supports both DMA_PRIVATE and DMA_MEMCPY (Manivannan Sadhasivam)
- Add pci-epf-test and pci_endpoint_test support for capabilities
(Niklas Cassel)
- Add Endpoint test for consecutive BARs (Niklas Cassel)
- Remove redundant comparison from Endpoint BAR test because a > 1MB
BAR can always be exactly covered by iterating with a 1MB buffer
(Hans Zhang)
- Move and convert PCI Endpoint tests from tools/pci to Kselftests
(Manivannan Sadhasivam)
Apple PCIe controller driver:
- Convert StreamID mapping configuration from a bus notifier to the
.enable_device() and .disable_device() callbacks (Marc Zyngier)

- Add Requester ID to StreamID mapping configuration when enabling
devices (Frank Li)

- Add suspend/resume support for i.MX8MQ, i.MX8Q, and i.MX95 (Richard
Zhu)
- Add DT compatible string 'fsl,imx8q-pcie-ep' and driver support for

Li)
- Add DT binding for optional i.MX95 Refclk and driver support to
enable it if the platform hasn't enabled it (Richard Zhu)
- Configure PHY based on controller being in Root Complex or Endpoint
mode (Frank Li)
- Rely on dbi2 and iATU base addresses from DT via
dw_pcie_get_resources() instead of hardcoding them (Richard Zhu)
- Deassert apps_reset in imx_pcie_deassert_core_reset() since it is
asserted in imx_pcie_assert_core_reset() (Richard Zhu)
- Add missing reference clock enable or disable logic for IMX6SX,
IMX7D, IMX8MM (Richard Zhu)
- Remove redundant imx7d_pcie_init_phy() since
imx7d_pcie_enable_ref_clk() does the same thing (Richard Zhu)
Freescale Layerscape PCIe controller driver:
- Simplify by using syscon_regmap_lookup_by_phandle_args() instead
of syscon_regmap_lookup_by_phandle() followed by
of_property_read_u32_array() (Krzysztof Kozlowski)
Marvell MVEBU PCIe controller driver:
- Add MODULE_DEVICE_TABLE() to enable module autoloading (Liao Chen)
MediaTek PCIe Gen3 controller driver:
- Use clk_bulk_prepare_enable() instead of separate
clk_bulk_prepare() and clk_bulk_enable() (Lorenzo Bianconi)
- Rearrange reset assert/deassert so they're both done in the
*_power_up() callbacks (Lorenzo Bianconi)
- Document that Airoha EN7581 requires PHY init and power-on before
PHY reset deassert, unlike other MediaTek Gen3 controllers (Lorenzo
Bianconi)
- Move Airoha EN7581 post-reset delay from the en7581 clock .enable()
method to mtk_pcie_en7581_power_up() (Lorenzo Bianconi)
- Sleep instead of delay during Airoha EN7581 power-up, since this is
a non-atomic context (Lorenzo Bianconi)
- Skip PERST# assertion on Airoha EN7581 during probe and
suspend/resume to avoid a hardware defect (Lorenzo Bianconi)
- Enable async probe to reduce system startup time (Douglas Anderson)
Microchip PolarFlare PCIe controller driver:
- Set up the inbound address translation based on whether the
platform allows coherent or non-coherent DMA (Daire McNamara)
- Update DT binding such that platforms are DMA-coherent by default
and must specify 'dma-noncoherent' if needed (Conor Dooley)
Mobiveil PCIe controller driver:
- Convert mobiveil-pcie.txt to YAML and update 'interrupt-names'
and 'reg-names' (Frank Li)
Qualcomm PCIe controller driver:
- Add DT SM8550 and SM8650 optional 'global' interrupt for link
events (Neil Armstrong)
- Add DT 'compatible' strings for IPQ5424 PCIe controller (Manikanta
Mylavarapu)
- If 'global' IRQ is supported for detection of Link Up events, tell
DWC core not to wait for link up (Krishna chaitanya chundru)
Renesas R-Car PCIe controller driver:
- Avoid passing stack buffer as resource name (King Dix)
Rockchip PCIe controller driver:
- Simplify clock and reset handling by using bulk interfaces (Anand
Moon)
- Pass typed rockchip_pcie (not void) pointer to
rockchip_pcie_disable_clocks() (Anand Moon)
- Return -ENOMEM, not success, when pci_epc_mem_alloc_addr() fails
(Dan Carpenter)
Rockchip DesignWare PCIe controller driver:
- Use dll_link_up IRQ to detect Link Up and enumerate devices so
users don't have to manually rescan (Niklas Cassel)
- Tell DWC core not to wait for link up since the 'sys' interrupt is
required and detects Link Up events (Niklas Cassel)
Synopsys DesignWare PCIe controller driver:
- Don't wait for link up in DWC core if driver can detect Link Up
event (Krishna chaitanya chundru)
- Update ICC and OPP votes after Link Up events (Krishna chaitanya
chundru)
- Always stop link in dw_pcie_suspend_noirq(), which is required at
least for i.MX8QM to re-establish link on resume (Richard Zhu)
- Drop racy and unnecessary LTSSM state check before sending
PME_TURN_OFF message in dw_pcie_suspend_noirq() (Richard Zhu)
- Add struct of_pci_range.parent_bus_addr for devices that need their
immediate parent bus address, not the CPU address, e.g., to program
an internal Address Translation Unit (iATU) (Frank Li)
TI DRA7xx PCIe controller driver:
- Simplify by using syscon_regmap_lookup_by_phandle_args() instead of
syscon_regmap_lookup_by_phandle() followed by
of_parse_phandle_with_fixed_args() or of_property_read_u32_index()
(Krzysztof Kozlowski)

HID: amd_sfh: Use always-managed version of pcim_intx()
pci_intx() is a hybrid function which can sometimes be managed through devres. To remove this hybrid nature from pci_intx(), it is necessary to port users to either an always-managed or a never-managed version. All users of amd_mp2_pci_remove(), where pci_intx() is used, call pcim_enable_device(), which is why the driver needs the always-managed version. Replace pci_intx() with pcim_intx().

HID: amd_sfh: Add support to export device operating states
Add support to export device operating states, such as laptop placement, platform types and propagate this data to AMD PMF driver for use in actions. To retrieve the device operating states data, SRA sensor support need to be enabled in AMD SFH driver. So add support to enable the SRA sensor. Also, remove explicit assignments to sensor_index enum.

HID: amd_sfh: Switch to device-managed dmam_alloc_coherent()
Using the device-managed version allows to simplify clean-up in probe()
error path.
Additionally, this device-managed ensures proper cleanup, which helps to
resolve memory errors, page faults, btrfs going read-only, and btrfs
disk corruption.

HID: amd_sfh: free driver_data after destroying hid device
HID driver callbacks aren't called anymore once hid_destroy_device() has been called. Hence, hid driver_data should be freed only after the hid_destroy_device() function returned as driver_data is used in several callbacks. I observed a crash with kernel 6.10.0 on my T14s Gen 3, after enabling KASAN to debug memory allocation, I got this output: [ 13.050438] ================================================================== [ 13.054060] BUG: KASAN: slab-use-after-free in amd_sfh_get_report+0x3ec/0x530 [amd_sfh] [ 13.054809] psmouse serio1: trackpoint: Synaptics TrackPoint firmware: 0x02, buttons: 3/3 [ 13.056432] Read of size 8 at addr ffff88813152f408 by task (udev-worker)/479 [ 13.060970] CPU: 5 PID: 479 Comm: (udev-worker) Not tainted 6.10.0-arch1-2 #1 893bb55d7f0073f25c46adbb49eb3785fefd74b0 [ 13.063978] Hardware name: LENOVO 21CQCTO1WW/21CQCTO1WW, BIOS R22ET70W (1.40 ) 03/21/2024 [ 13.067860] Call Trace: [ 13.069383] input: TPPS/2 Synaptics TrackPoint as /devices/platform/i8042/serio1/input/input8 [ 13.071486] <TASK> [ 13.071492] dump_stack_lvl+0x5d/0x80 [ 13.074870] snd_hda_intel 0000:33:00.6: enabling device (0000 -> 0002) [ 13.078296] ?

HID: amd_sfh: Move sensor discovery before HID device initialization
Sensors discovery is independent of HID device initialization. If sensor
discovery fails after HID initialization, then the HID device needs to be
deinitialized. Therefore, sensors discovery should be moved before HID
device initialization.

Kbuild updates for v6.10
- Avoid 'constexpr', which is a keyword in C23
- Allow 'dtbs_check' and 'dt_compatible_check' run independently of
'dt_binding_check'
- Fix weak references to avoid GOT entries in position-independent
code generation
- Convert the last use of 'optional' property in arch/sh/Kconfig
- Remove support for the 'optional' property in Kconfig
- Remove support for Clang's ThinLTO caching, which does not work with
the .incbin directive
- Change the semantics of $(src) so it always points to the source
directory, which fixes Makefile inconsistencies between upstream and

kbuild: use $(src) instead of $(srctree)/$(src) for source directory
Kbuild conventionally uses $(obj)/ for generated files, and $(src)/ for
checked-in source files. It is merely a convention without any functional
difference. In fact, $(obj) and $(src) are exactly the same, as defined
in scripts/Makefile.build:
src := $(obj)
When the kernel is built in a separate output directory, $(src) does
not accurately reflect the source directory location. While Kbuild
resolves this discrepancy by specifying VPATH=$(srctree) to search for
source files, it does not cover all cases. For example, when adding a
header search path for local headers, -I$(srctree)/$(src) is typically
passed to the compiler.
This introduces inconsistency between upstream and downstream Makefiles
because $(src) is used instead of $(srctree)/$(src) for the latter.
To address this inconsistency, this commit changes the semantics of
$(src) so that it always points to the directory in the source tree.
Going forward, the variables used in Makefiles will have the following
meanings:
$(obj) - directory in the object tree
$(src) - directory in the source tree (changed by this commit)
$(objtree) - the top of the kernel object tree
$(srctree) - the top of the kernel source tree
Consequently, $(srctree)/$(src) in upstream Makefiles need to be replaced
with $(src).
