2024-07-05Merge v6.10-rc6 into drm-nextDaniel Vetter
The exynos-next pull is based on a newer -rc than drm-next. hence backmerge first to make sure the unrelated conflicts we accumulated don't end up randomly in the exynos merge pull, but are separated out. Conflicts are all benign: Adjacent changes in amdgpu and fbdev-dma code, and cherry-pick conflict in xe. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2024-07-03driver core: have match() callback in struct bus_type take a const *Greg Kroah-Hartman
In the match() callback, the struct device_driver * should not be changed, so change the function callback to be a const *. This is one step of many towards making the driver core safe to have struct device_driver in read-only memory. Because the match() callback is in all busses, all busses are modified to handle this properly. This does entail switching some container_of() calls to container_of_const() to properly handle the constant *. For some busses, like PCI and USB and HV, the const * is cast away in the match callback as those busses do want to modify those structures at this point in time (they have a local lock in the driver structure.) That will have to be changed in the future if they wish to have their struct device * in read-only-memory. Cc: Rafael J.

2024-07-02platform/x86: toshiba_acpi: Fix quickstart quirk handlingArmin Wolf
The global hci_hotkey_quickstart quirk flag is tested in toshiba_acpi_enable_hotkeys() before the quirk flag is properly initialized based on SMBIOS data. This causes the quirk to be applied to all models, some of which behave erratically as a result. Fix this by initializing the global quirk flags during module initialization before registering the ACPI driver. This also allows us to mark toshiba_dmi_quirks[] as __initconst.

2024-06-24platform/x86: lg-laptop: Use ACPI device handle when evaluating WMAB/WMBBArmin Wolf
On the LG Gram 16Z90S, the WMAB and WMBB ACPI methods are not mapped under \XINI, but instead are mapped under \_SB.XINI. The reason for this is that the LGEX0820 ACPI device used by this driver is mapped at \_SB.XINI, so the ACPI methods where moved as well to appear below the LGEX0820 ACPI device. Fix this by using the ACPI handle from the ACPI device when evaluating both methods.

When reading token data from sysfs on my Inspiron 3505, the token locations and values are wrong.

This however is not true as soon as da_tokens[] contains zeroed token entries. Those entries are being skipped when initialising token_attrs, breaking the core assumption of match_attribute().

2024-05-31platform/x86/intel: TPMI domain id and CPU mappingSrinivas Pandruvada
Each TPMI power domain includes a group of CPUs. Several power management settings in this case applicable to a group of CPUs. There can be several power domains in a CPU package. So, provide interfaces for: - Get power domain id for a Linux CPU - Get mask of Linux CPUs in a power domain Hardware Punit uses different CPU numbering, which is not based on APIC (Advanced Programmable Interrupt Controller) CPU numbering. The Linux CPU numbering is based on APIC CPU numbering. Some PM features like Intel Speed Select, the CPU core mask provided by the hardware is based on the Punit CPU numbering. To use the core mask, this mask needs to be converted to a Linux CPUs mask. So, provide interfaces for: - Convert to a Linux CPU number from a Punit CPU number - Convert to a Punit CPU number from a Linux CPU number On each CPU online, MSR 0x54 is used to read the mapping and stores in a per cpu array. Create a hash for faster searching of a Linux CPU number from a Punit CPU number.

2024-05-31platform/x86: ISST: Avoid some SkyLake server modelsSrinivas Pandruvada
Some SkyLake server variants don't support any SST functionality. No use of providing any SST related interfaces on them. All supported SkyLake servers provide mailbox interface via MSR. So check for the presence of MSR 0xB0 and 0xB1. If not present don't load common module. Move defines for MSR_OS_MAILBOX_INTERFACE and MSR_OS_MAILBOX_DATA to common header file to avoid duplicating them.

2024-05-31platform/x86: ISST: Add model specific loading for common moduleSrinivas Pandruvada
SST common module is loaded when model specific or TPMI SST driver registers for services. There are model specific features used in SST common modules which are checked with a CPU model list. So, this module is model specific. There are some use cases where loading the common module independently only on the supported CPU models helps. The first use case is for preventing SST TPMI module loading if the model specific features are not implemented. The second use case for presenting information to user space when SST is used in OOB (Out of Band) mode. 1. With TPMI, SST interface is architectural. This means that no need to add new PCI device IDs for new CPU models. This means that there can be lag in adding CPU models for the model specific features in the common module. For example, before adding CPU model to GRANITERAPIDS_D to hpm_cpu_ids[], SST is still functional for some features and but will get/set wrong data for features like SST-CP. This is because IOCTL ISST_IF_GET_PHY_ID, will not give correct mapping for newer CPU models. So adding explicit model check during load time will prevent such cases. For unsupported CPU models, common driver will fail to load and hence dependent modules will not be loaded. 2. When the SST TPMI features are controlled by some OOB agent (not from OS interface), even if the CPU model is supported, there will be no user space interface available for tools as SST TPMI modules will not be loaded. User space interface is registered when TPMI modules call isst_if_cdev_register(). Even in this case user space orchestrator software needs to get power domain information to schedule workload and get/set turbo ratio limits. This information is exposed by the common module using IOCTLs ISST_IF_GET_PHY_ID and ISST_IF_MSR_COMMAND respectively. Since the user space MSR access can be locked, direct MSR access from the user space is not an option using /dev/cpu/*/msr. Converge all the existing model checks to one common place and use driver data to differentiate. On successful model check call isst_misc_reg().
