efi/libstub: arm: Print CPU boot mode and MMU state at boot
On 32-bit ARM, we may boot at HYP mode, or with the MMU and caches off (or both), even though the EFI spec does not actually support this. While booting at HYP mode is something we might tolerate, fiddling with the caches is a more serious issue, as disabling the caches is tricky to do safely from C code, and running without the Dcache makes it impossible to support unaligned memory accesses, which is another explicit requirement imposed by the EFI spec. So take note of the CPU mode and MMU state in the EFI stub diagnostic output so that we can easily diagnose any issues that may arise from this. E.g., EFI stub: Entering in SVC mode with MMU enabled Also, capture the CPSR and SCTLR system register values at EFI stub entry, and after ExitBootServices() returns, and check whether the MMU and Dcache were disabled at any point. If this is the case, a diagnostic message like the following will be emitted: efi: [Firmware Bug]: EFI stub was entered with MMU and Dcache disabled, please fix your firmware! efi: CPSR at EFI stub entry : 0x600001d3 efi: SCTLR at EFI stub entry : 0x00c51838 efi: CPSR after ExitBootServices() : 0x600001d3 efi: SCTLR after ExitBootServices(): 0x00c50838 Signed-off-by: Ard Biesheuvel <ardb@kernel.org> Reviewed-by: Leif Lindholm <leif@nuviainc.com> |

efi/libstub: arm: Omit arch specific config table matching array on arm64
On arm64, the EFI stub is built into the kernel proper, and so the stub can refer to its symbols directly. Therefore, the practice of using EFI configuration tables to pass information between them is never needed, so we can omit any code consuming such tables when building for arm64.

efi: Make it possible to disable efivar_ssdt entirely
In most cases, such as CONFIG_ACPI_CUSTOM_DSDT and CONFIG_ACPI_TABLE_UPGRADE, boot-time modifications to firmware tables are tied to specific Kconfig options. Currently this is not the case for modifying the ACPI SSDT via the efivar_ssdt kernel command line option and associated EFI variable. This patch adds CONFIG_EFI_CUSTOM_SSDT_OVERLAYS, which defaults disabled, in order to allow enabling or disabling that feature during the build.

efi: Replace zero-length array and use struct_size() helper
The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.
Lastly, make use of the sizeof_field() helper instead of an open-coded
version.
This issue was found with the help of Coccinelle and audited _manually_.

firmware/dmi: Report DMI Bios & EC firmware release
Some vendors like HPe or Dell, encode the release version of their BIOS
in the "System BIOS {Major|Minor} Release" fields of Type 0.
This information is used to know which bios release actually runs.
It could be used for some quirks, debugging sessions or inventory tasks.
A typical output for a Dell system running the 65.27 bios is :
[root@t1700 ~]# cat /sys/devices/virtual/dmi/id/bios_release
65.27
[root@t1700 ~]#
Servers that have a BMC encode the release version of their firmware in the
"Embedded Controller Firmware {Major|Minor} Release" fields of Type 0.
This information is used to know which BMC release actually runs.
It could be used for some quirks, debugging sessions or inventory tasks.
A typical output for a Dell system running the 3.75 bmc release is :
[root@t1700 ~]# cat /sys/devices/virtual/dmi/id/ec_firmware_release
3.75

ARM/SoC: drivers for v5.7
These are updates to SoC specific drivers that did not have
another subsystem maintainer tree to go through for some
reason:
- Some bus and memory drivers for the MIPS P5600 based
Baikal-T1 SoC that is getting added through the MIPS tree.
- There are new soc_device identification drivers for TI K3,
Qualcomm MSM8939
- New reset controller drivers for NXP i.MX8MP, Renesas
RZ/G1H, and Hisilicon hi6220
- The SCMI firmware interface can now work across ARM SMC/HVC
as a transport.
- Mediatek platforms now use a new driver for their "MMSYS"
hardware block that controls clocks and some other aspects
in behalf of the media and gpu drivers.
- Some Tegra processors have improved power management
support, including getting woken up by the PMIC and cluster
power down during idle.
- A new v4l staging driver for Tegra is added.
- Cleanups and minor bugfixes for TI, NXP, Hisilicon,
Mediatek, and Tegra.

ARM: SoC changes for v5.8
One new platform gets added, the Realtek RTD1195, which is an older Cortex-a7 based relative of the RTD12xx chips that are already supported in arch/arm64. The platform may also be extended to support running 32-bit kernels on those 64-bit chips for memory-constrained machines. In the Renesas shmobile platform, we gain support for "RZ/G1H" or R8A7742, an eight-core chip based on Cortex-A15 and Cortex-A7 cores, originally released in 2016 as one of the last high-end 32-bit designs. There is ongoing cleanup for the integrator, tegra, imx, and omap2 platforms, with integrator getting very close to the goal of having zero code in arch/arm/, and omap2 moving more of the chip specifics from old board code into device tree files. The Versatile Express platform is made more modular, with built-in drivers now becoming loadable modules. This is part of a greater effort for the Android OS to have a common kernel binary for all platforms and any platform specific code in loadable modules. The PXA platform drops support for Compulab's pxa2xx boards that had rather unusual flash and PCI drivers but no known users remaining. All device drivers specific to those boards can now get removed as well. Across platforms, there is ongoing cleanup, with Geert and Rob revisiting some a lot of Kconfig options.

arm64 updates for 5.8
- Branch Target Identification (BTI)
* Support for ARMv8.5-BTI in both user- and kernel-space. This
allows branch targets to limit the types of branch from which
they can be called and additionally prevents branching to
arbitrary code, although kernel support requires a very recent
toolchain.
* Function annotation via SYM_FUNC_START() so that assembly
functions are wrapped with the relevant "landing pad"
instructions.
* BPF and vDSO updates to use the new instructions.
* Addition of a new HWCAP and exposure of BTI capability to
userspace via ID register emulation, along with ELF loader
support for the BTI feature in .note.gnu.property.
* Non-critical fixes to CFI unwind annotations in the sigreturn
trampoline.
- Shadow Call Stack (SCS)
* Support for Clang's Shadow Call Stack feature, which reserves
platform register x18 to point at a separate stack for each
task that holds only return addresses. This protects function
return control flow from buffer overruns on the main stack.
* Save/restore of x18 across problematic boundaries (user-mode,
hypervisor, EFI, suspend, etc).
* Core support for SCS, should other architectures want to use it
too.
* SCS overflow checking on context-switch as part of the existing
stack limit check if CONFIG_SCHED_STACK_END_CHECK=y.
- CPU feature detection
* Removed numerous "SANITY CHECK" errors when running on a system
with mismatched AArch32 support at EL1. This is primarily a
concern for KVM, which disabled support for 32-bit guests on
such a system.
* Addition of new ID registers and fields as the architecture has
been extended.
- Perf and PMU drivers
* Minor fixes and cleanups to system PMU drivers.
- Hardware errata
* Unify KVM workarounds for VHE and nVHE configurations.
* Sort vendor errata entries in Kconfig.
- Secure Monitor Call Calling Convention (SMCCC)
* Update to the latest specification from Arm (v1.2).
* Allow PSCI code to query the SMCCC version.
- Software Delegated Exception Interface (SDEI)
* Unexport a bunch of unused symbols.
* Minor fixes to handling of firmware data.
- Pointer authentication
* Add support for dumping the kernel PAC mask in vmcoreinfo so
that the stack can be unwound by tools such as kdump.
* Simplification of key initialisation during CPU bringup.
- BPF backend
* Improve immediate generation for logical and add/sub
instructions.
- vDSO
- Minor fixes to the linker flags for consistency with other
architectures and support for LLVM's unwinder.
- Clean up logic to initialise and map the vDSO into userspace.
- ACPI
- Work around for an ambiguity in the IORT specification relating
to the "num_ids" field.
- Support _DMA method for all named components rather than only
PCIe root complexes.
- Minor other IORT-related fixes.
- Miscellaneous
* Initialise debug traps early for KGDB and fix KDB cacheflushing
deadlock.
* Minor tweaks to early boot state (documentation update, set
TEXT_OFFSET to 0x0, increase alignment of PE/COFF sections).
* Refactoring and cleanup

"A sizeable pile of arm64 updates for 5.8.
Summary below, but the big two features are support for Branch Target
Identification and Clang's Shadow Call stack. The latter is currently
arm64-only, but the high-level parts are all in core code so it could
easily be adopted by other architectures pending toolchain support

Qualcomm driver updates for v5.8
This contains a large set of cleanups, bug fixes, general improvements and documentation fixes for the RPMH driver. It adds a debugfs mechanism for inspecting Command DB. Socinfo got the "soc_id" attribute defines and definitions for a various variants of MSM8939. RPMH, RPMPD and RPMHPD where made possible to build as modules, but RPMH had to be reverted due to a compilation issue when tracing is enabled. RPMHPD gained power-domains for the SM8250 voltage corners. The SCM driver gained fixes for two build warnings and the SMP2P had an unnecessary error print removed. -----BEGIN PGP SIGNATURE----- iQJPBAABCAA5FiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAl7DZcEbHGJqb3JuLmFu ZGVyc3NvbkBsaW5hcm8ub3JnAAoJEAsfOT8Nma3FEwIQAK1TrENzsRjB23fY4pEW +hN/SkfMjNPsinmyNOHCo03MQzdFIKUl40aNvaHh3foQXaSG4TW12iot9Ul5nsxn /u6dCSzl15FK7pHYj/VQPWTz2WvpANVqsm6G5tf43hBg2TnStbK1AsxgJ6aq47fp QHehMbfeKpF/gltEowv1b+H7xwNFY7eqlQ9O9umYm3hUQh3Bl5mI6PdbkazDdO1j l/vHuQKkZXRdHtD1BxGBfvhPtM4NWDbOPeWWrw8HRFM5muDPgK9mXMRGDcv+fpHq 4I3670xiTWK1Mfz9+FRBMoxLkIWT6zXILg9aNzuZMTOLoNRt3s6VNdne6uf3naND 2Nrcu7t0b+4xWGbdwwpiAFZm8C6l+R1WTCiY4iOJXDychhVvyVwOLzPdZ4i8Pzx9 a4UJDElu8xj2g++oCcjK816IdNwkA46bM7qVz4mkHRUBMkmK9AU7okBA9HQfbP64 MrKPaUljyZuy7zonpJJBBDKLDEFa9a1pI8sehU8p+MUldxYB/4f/iGC3KzyDvv4Q Uzj6AqdP5pjgIxz98YgpOPPl8pwg1c5OgblNLWoHj4yTaqUzT0ZHIRyQO/O/+3Lg HwCrSy+f3+tgzts3DhyVRmOkOXFHfflSdf4rfKtbiq435yB2dz60dt77dJ0jQuBV M9MiF+SE9oASUupPhs47kNte =tkhb -----END PGP SIGNATURE----- Merge tag 'qcom-drivers-for-5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/drivers Qualcomm driver updates for v5.8 This contains a large set of cleanups, bug fixes, general improvements and documentation fixes for the RPMH driver.
