2022-03-04sysfb: Enable boot time VESA graphic mode selectionMichal Suchanek
Since switch to simplefb/simpledrm VESA graphic mode selection with vga= kernel parameter is no longer available with legacy BIOS. The x86 realmode boot code enables the VESA graphic modes when option FB_BOOT_VESA_SUPPORT is enabled. This option is selected by vesafb but not simplefb/simpledrm. To enable use of VESA modes with simplefb in legacy BIOS boot mode drop dependency of BOOT_VESA_SUPPORT on FB, also drop the FB_ prefix. Select the option from sysfb rather than the drivers that depend on it. The BOOT_VESA_SUPPORT is not specific to framebuffer but rather to x86 platform, move it from fbdev to x86 Kconfig.

2022-03-03ACPI: APEI: explicit init of HEST and GHES in apci_init()Shuai Xue
From commit e147133a42cb ("ACPI / APEI: Make hest.c manage the estatus memory pool") was merged, ghes_init() relies on acpi_hest_init() to manage the estatus memory pool. On the other hand, ghes_init() relies on sdei_init() to detect the SDEI version and (un)register events. The dependencies are as follows: ghes_init() => acpi_hest_init() => acpi_bus_init() => acpi_init() ghes_init() => sdei_init() HEST is not PCI-specific and initcall ordering is implicit and not well-defined within a level. Based on above, remove acpi_hest_init() from acpi_pci_root_init() and convert ghes_init() and sdei_init() from initcalls to explicit calls in the following order: acpi_hest_init() ghes_init() sdei_init() Signed-off-by: Shuai Xue <xueshuai@linux.alibaba.com> Signed-off-by: Rafael J.

git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/drivers Qualcomm driver updates for v5.18 This refactors the Qualcomm mdt file loader, to partially decouple it from the SCM peripheral-authentication-service. This is needed as newer platforms, such as the Qualcomm SM8450, require the metadata to remain accessible to TrustZone during a longer time. This is followed by the introduction of remoteproc drivers for SM8450 (Snapdragon 8 Gen 1). It changes the way hardware version differences are handled in the LLCC driver and introduces support for Qualcomm SM8450. While updating the dt binding for LLCC it also introduces the missing SM8350 compatible. The ocmem and aoss drivers gains missing put_device() calls and rpmpd gains a missing check for kcalloc() failure. The SPM driver is updated to avoid instantiating the SPM cpuidle devices if the CPUs aren't controlled by SPM, such as when Snapdragon 8916 operates in 32-bit mode without PSCI. The RPM power-domain driver gains MSM8226 support. Lastly the socinfo driver gains knowledge about a few new SoCs and PMICs. * tag 'qcom-drivers-for-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (37 commits) soc: qcom: rpmpd: Add MSM8226 support dt-bindings: power: rpmpd: Add MSM8226 to rpmpd binding soc: qcom: mdt_loader: Fix split-firmware condition dt-bindings: arm: msm: Add LLCC compatible for SM8450 dt-bindings: arm: msm: Add LLCC compatible for SM8350 soc: qcom: llcc: Add configuration data for SM8450 SoC soc: qcom: llcc: Update register offsets for newer LLCC HW soc: qcom: llcc: Add missing llcc configuration data soc: qcom: llcc: Add write-cache cacheable support soc: qcom: llcc: Update the logic for version info extraction soc: qcom: llcc: Add support for 16 ways of allocation soc: qcom: socinfo: Add some more PMICs and SoCs firmware: qcom: scm: Add support for MC boot address API firmware: qcom: scm: Drop cpumask parameter from set_boot_addr() firmware: qcom: scm: Simplify set_cold/warm_boot_addr() cpuidle: qcom-spm: Check if any CPU is managed by SPM remoteproc: qcom: pas: Add SM8450 remoteproc support dt-bindings: remoteproc: qcom: pas: Add SM8450 PAS compatibles remoteproc: qcom: pas: Carry PAS metadata context soc: qcom: mdt_loader: Extract PAS operations ...

2022-03-01efi: fix return value of __setup handlersRandy Dunlap
When "dump_apple_properties" is used on the kernel boot command line, it causes an Unknown parameter message and the string is added to init's argument strings: Unknown kernel command line parameters "dump_apple_properties BOOT_IMAGE=/boot/bzImage-517rc6 efivar_ssdt=newcpu_ssdt", will be passed to user space. Run /sbin/init as init process with arguments: /sbin/init dump_apple_properties with environment: HOME=/ TERM=linux BOOT_IMAGE=/boot/bzImage-517rc6 efivar_ssdt=newcpu_ssdt Similarly when "efivar_ssdt=somestring" is used, it is added to the Unknown parameter message and to init's environment strings, polluting them (see examples above). Change the return value of the __setup functions to 1 to indicate that the __setup options have been handled.

2022-02-28efivars: Respect "block" flag in efivar_entry_set_safe()Jann Horn
When the "block" flag is false, the old code would sometimes still call check_var_size(), which wrongly tells ->query_variable_store() that it can block. As far as I can tell, this can't really materialize as a bug at the moment, because ->query_variable_store only does something on X86 with generic EFI, and in that configuration we always take the efivar_entry_set_nonblocking() path.

It looks like the old QCOM_SCM_BOOT_SET_ADDR API is broken on some MSM8916 firmware versions that implement the newer SMC32 calling convention. It just returns -EINVAL no matter which arguments are being passed. This does not cause any problems downstream because it first tries to use the new multi-cluster API replacement which is working fine. Implement support for the multi-cluster variant of the SCM call by attempting it first but still fallback to the old call in case of an error. Also, to be absolutely sure only use the multi-cluster variant with the SMC calling convention since older platforms should not need this.

2022-02-03firmware: qcom: scm: Drop cpumask parameter from set_boot_addr()Stephan Gerhold
qcom_scm_set_cold/warm_boot_addr() currently take a cpumask parameter, but it's not very useful because at the end we always set the same entry address for all CPUs. This also allows speeding up probe of cpuidle-qcom-spm a bit because only one SCM call needs to be made to the TrustZone firmware, instead of one per CPU. The main reason for this change is that it allows implementing the "multi-cluster" variant of the set_boot_addr() call more easily without having to rely on functions that break in certain build configurations or that are not exported to modules.

2022-02-03firmware: qcom: scm: Simplify set_cold/warm_boot_addr()Stephan Gerhold
The qcom_scm_set_cold/warm_boot_addr() implementations have a lot of functionality that is actually not used. For example, set_warm_boot_addr() caches the last used entry address and skips making the SCM call when the entry address is unchanged. But there is actually just a single call of qcom_scm_set_warm_boot_addr() in the whole kernel tree, which always configures the entry address to cpu_resume_arm(). Simplify this by having a single qcom_scm_set_boot_addr() function for both cold and warm boot address. This is totally sufficient for the functionality supported in the mainline tree.

2022-01-23efi: runtime: avoid EFIv2 runtime services on Apple x86 machinesArd Biesheuvel
Aditya reports [0] that his recent MacbookPro crashes in the firmware when using the variable services at runtime. The culprit appears to be a call to QueryVariableInfo(), which we did not use to call on Apple x86 machines in the past as they only upgraded from EFI v1.10 to EFI v2.40 firmware fairly recently, and QueryVariableInfo() (along with UpdateCapsule() et al) was added in EFI v2.00. The only runtime service introduced in EFI v2.00 that we actually use in Linux is QueryVariableInfo(), as the capsule based ones are optional, generally not used at runtime (all the LVFS/fwupd firmware update infrastructure uses helper EFI programs that invoke capsule update at boot time, not runtime), and not implemented by Apple machines in the first place. QueryVariableInfo() is used to 'safely' set variables, i.e., only when there is enough space. This prevents machines with buggy firmwares from corrupting their NVRAMs when they run out of space. Given that Apple machines have been using EFI v1.10 services only for the longest time (the EFI v2.0 spec was released in 2006, and Linux support for the newly introduced runtime services was added in 2011, but the MacbookPro12,1 released in 2015 still claims to be EFI v1.10 only), let's avoid the EFI v2.0 ones on all Apple x86 machines.

2022-01-19RISC-V: Introduce sv48 support without relocatable kernelPalmer Dabbelt
This patchset allows to have a single kernel for sv39 and sv48 without being relocatable. The idea comes from Arnd Bergmann who suggested to do the same as x86, that is mapping the kernel to the end of the address space, which allows the kernel to be linked at the same address for both sv39 and sv48 and then does not require to be relocated at runtime. This implements sv48 support at runtime. The kernel will try to boot with 4-level page table and will fallback to 3-level if the HW does not support it. Folding the 4th level into a 3-level page table has almost no cost at runtime. Note that kasan region had to be moved to the end of the address space since its location must be known at compile-time and then be valid for both sv39 and sv48 (and sv57 that is coming). * riscv-sv48-v3: riscv: Explicit comment about user virtual address space size riscv: Use pgtable_l4_enabled to output mmu_type in cpuinfo riscv: Implement sv48 support asm-generic: Prepare for riscv use of pud_alloc_one and pud_free riscv: Allow to dynamically define VA_BITS riscv: Introduce functions to switch pt_ops riscv: Split early kasan mapping to prepare sv48 introduction riscv: Move KASAN mapping next to the kernel mapping riscv: Get rid of MAXPHYSMEM configs Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>

By adding a new 4th level of page table, give the possibility to 64bit kernel to address 2^48 bytes of virtual address: in practice, that offers 128TB of virtual address space to userspace and allows up to 64TB of physical memory. If the underlying hardware does not support sv48, we will automatically fallback to a standard 3-level page table by folding the new PUD level into PGDIR level.

Although this won't hinder the kernel build itself, we're going to catch up before RC1" * tag 'sound-5.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (415 commits) ALSA: hda: intel-dsp-config: reorder the config table ALSA: hda: intel-dsp-config: add JasperLake support ALSA: hda: cs35l41: fix double free on error in probe() ALSA: hda: Fix dependencies of CS35L41 on SPI/I2C buses ALSA: hda: Fix dependency on ASoC cs35l41 codec ASoC: cs35l41: Add support for hibernate memory retention mode ASoC: cs35l41: Update handling of test key registers ALSA: intel_hdmi: Check for error num after setting mask ASoC: wcd9335: Keep a RX port value for each SLIM RX mux ASoC: amd: acp: acp-mach: Change default RT1019 amp dev id ALSA: virmidi: Remove duplicated code ALSA: seq: virmidi: Add a drain operation ASoC: topology: Fix typo ASoC: fsl_asrc: refine the check of available clock divider ASoC: Intel: bytcr_rt5640: Add support for external GPIO jack-detect ASoC: Intel: bytcr_rt5640: Support retrieving the codec IRQ from the AMCR0F28 ACPI dev ASoC: rt5640: Add support for boards with an external jack-detect GPIO ASoC: rt5640: Allow snd_soc_component_set_jack() to override the codec IRQ ASoC: rt5640: Change jack_work to a delayed_work ASoC: rt5640: Fix possible NULL pointer deref on resume ...
