2022-09-07MIPS: octeon: Get rid of preprocessor directives around RESERVE32Alexander Sverdlin2-20/+11
Some of them were pointless because CONFIG_CAVIUM_RESERVE32 is now always defined, some were not enough (Yu Zhao reported "Failed to allocate CAVIUM_RESERVE32 memory area" error). Removing the directives allows for compiler coverage of RESERVE32 code and replacing one of [always-true] "ifdef" with a compiler conditional fixes the [cosmetic] error message.

The iommu-dma layer is now mostly encapsulated by iommu_dma_ops, with only a couple more public interfaces left pertaining to MSI integration.

2022-09-07iommu/dma: Clean up KconfigRobin Murphy1-1/+0
Although iommu-dma is a per-architecture chonce, that is currently implemented in a rather haphazard way. Selecting from the arch Kconfig was the original logical approach, but is complicated by having to manage dependencies; conversely, selecting from drivers ends up hiding the architecture dependency *too* well. Instead, let's just have it enable itself automatically when IOMMU API support is enabled for the relevant architectures. It can't get much clearer than that.

2022-09-06bpf: x86: Support in-register struct arguments in trampoline programsYonghong Song1-17/+51
In C, struct value can be passed as a function argument. For small structs, struct value may be passed in one or more registers. For trampoline based bpf programs, this would cause complication since one-to-one mapping between function argument and arch argument register is not valid any more. The latest llvm16 added bpf support to pass by values for struct up to 16 bytes ([1]). This is also true for x86_64 architecture where two registers will hold the struct value if the struct size is >8 and <= 16. This may not be true if one of struct member is 'double' type but in current linux source code we don't have such instance yet, so we assume all >8 && <= 16 struct holds two general purpose argument registers. Also change on-stack nr_args value to the number of registers holding the arguments. This will permit bpf_get_func_arg() helper to get all argument values.

2022-09-06arm64/sysreg: Add hwcap for SVE EBF16Mark Brown4-0/+4
SVE has a separate identification register indicating support for BFloat16 operations. Add a hwcap identifying support for EBF16 in this register, mirroring what we did for the non-SVE case. While there is currently an architectural requirement for BF16 support to be the same in SVE and non-SVE contexts there are separate identification registers this separate hwcap helps avoid issues if that requirement were to be relaxed in the future, we have already chosen to have a separate capability for base BF16 support.

2022-09-06arm64: dts: qcom: msm8916-samsung-serranove: Add magnetometerJakob Hauser1-0/+9
Add magnetometer Yamaha YAS537 to the DeviceTree of samsung-serranove. The YAS537 variant was recently added to the Yamaha YAS magnetometers driver [1]. In the DeviceTree of samsung-serranove for the Android kernel, there is unfortunately no information on interrupts or pinctrl [2]. In the Android kernel driver for magnetometer Yamaha YAS537, there is a device-specific matrix to correct an ellipsoid shape of the measure values into a sphere shape [3]. This could be converted and applied to a mount-matrix. However, the current state of the mainline Yamaha YAS537 driver needs post-process calibration in userspace anyway, as it lacks a formula to center the measure values around zero. The correction of the ellipsoid into a sphere can be done in the post-process calibration as well. A mount-matrix is needed nonetheless. When putting samsung-serranove flat on a table in portrait orientation heading north, the Yamaha YAS537 magnetometer axes natively point X+ to north, Y+ to east and Z+ into the ground, which corresponds to a common way to define the Earth's magnetic field coordinate system [4]. According to the IIO definition, it should be Y+ to north, X+ to east and Z+ upwards [5], which corresponds to a common device coordinate system and eases sensor fusing.

This patch adds efistub booting support, which is the standard UEFI boot protocol for LoongArch to use. We use generic efistub, which means we can pass boot information (i.e., system table, memory map, kernel command line, initrd) via a light FDT and drop a lot of non-standard code. We use a flat mapping to map the efi runtime in the kernel's address space. In efi, VA = PA; in kernel, VA = PA + PAGE_OFFSET. As a result, flat mapping is not identity mapping, SetVirtualAddressMap() is still needed for the efi runtime.

This is not something that is supported by the architecture, but was done anyway to increase compatibility with user space software, which mostly targeted x86 at the time and did not care about aligned accesses. This feature is one of the remaining impediments to being able to switch to 64-bit kernels on 64-bit capable hardware running 32-bit user space, so let's implement it for the arm64 compat layer as well. Note that the intent is to implement the exact same handling of misaligned multi-word loads and stores as the 32-bit kernel does, including what appears to be missing support for user space programs that rely on SETEND to switch to a different byte order and back. Also, like the 32-bit ARM version, we rely on the faulting address reported by the CPU to infer the memory address, instead of decoding the instruction fully to obtain this information. This implementation is taken from the 32-bit ARM tree, with all pieces removed that deal with instructions other than LDRD/STRD and LDM/STM, or that deal with alignment exceptions taken in kernel mode.

2022-09-06arm64/bti: Disable in kernel BTI when cross section thunks are brokenMark Brown1-0/+2
GCC does not insert a `bti c` instruction at the beginning of a function when it believes that all callers reach the function through a direct branch[1]. Unfortunately the logic it uses to determine this is not sufficiently robust, for example not taking account of functions being placed in different sections which may be loaded separately, so we may still see thunks being generated to these functions. If that happens, the first instruction in the callee function will result in a Branch Target Exception due to the missing landing pad. While this has currently only been observed in the case of modules having their main code loaded sufficiently far from their init section to require thunks it could potentially happen for other cases so the safest thing is to disable BTI for the kernel when building with an affected toolchain.

Commit bcbb63b80284 ("ARM: dts: dra7: Separate AM57 dtsi files") disabled usb4_tm for am5748 devices since USB4 IP is not present in this SoC. The commit log explained the difference between AM5 and DRA7 families: AM5 and DRA7 SoC families have different set of modules in them so the SoC sepecific dtsi files need to be separated. e.g. Some of the major differences between AM576 and DRA76 DRA76x AM576x USB3 x USB4 x ATL x VCP x MLB x ISS x PRU-ICSS1 x PRU-ICSS2 x Then commit 176f26bcd41a ("ARM: dts: Add support for dra762 abz package") removed usb4_tm part from am5748.dtsi and introcuded new ti-sysc errors in dmesg: ti-sysc 48940000.target-module: clock get error for fck: -2 ti-sysc: probe of 48940000.target-module failed with error -2 Fixes: 176f26bcd41a ("ARM: dts: Add support for dra762 abz package") Signed-off-by: Romain Naour <romain.naour@skf.com> Signed-off-by: Romain Naour <romain.naour@smile.fr> Message-Id: <20220823072742.351368-1-romain.naour@smile.fr> Reviewed-by: Roger Quadros <rogerq@kernel.org> Signed-off-by: Tony Lindgren <tony@atomide.com>

2022-09-06arm64: dts: imx8mm-verdin: extend pmic voltagesPhilippe Schenker1-5/+5
Currently, we limited the voltages from the PMIC very strictly. This causes an issue with one Toradex SKU that uses a consumer-grade chip that is capable of going up to 1.8GHz at 1.00V. Extend the ranges to min/max values of the SoC operating ranges (table 10) in the datasheet. Detailed explanation as follows: BUCK2: - As already described above, the SKU with the consumer-grade chip needs a voltage of at least 1.00V. 1.05V is chosen now as this is listed as the maximum. Both industrial and consumer-grade chips have an absolute maximum rating of 1.15V which makes it still safe to put 1.05V - Lower the regulator-min value to the smallest value allowed from the Quad-A53, 1.2GHz version of the SoC BUCK3: - This regulator is used for SoC input voltages VDD_GPU, VDD_VPU and VDD_DRAM. - Use the smallest value of these three inputs as the regulator-min - Use the largest value of these three inputs as the regulator-max LDO2: - This LDO is used for VDD_SNVS_0P8 SoC input voltage. As this has a single nominal input voltage just put this in the middle of 0.8V.

Currently in pas_pci_init() a reference to the root node is leaked due to a missing of_node_put(). Instead just use of_root directly. Note that converting to of_find_compatible_node(NULL, ...) would not be entirely equivalent, because that would check the compatible property of the root node, whereas using of_root skips checking the root node and start the search at the first child of the root.

2022-09-05asm-generic: Conditionally enable do_softirq_own_stack() via Kconfig.Sebastian Andrzej Siewior9-9/+12
Remove the CONFIG_PREEMPT_RT symbol from the ifdef around do_softirq_own_stack() and move it to Kconfig instead. Enable softirq stacks based on SOFTIRQ_ON_OWN_STACK which depends on HAVE_SOFTIRQ_ON_OWN_STACK and its default value is set to !PREEMPT_RT. This ensures that softirq stacks are not used on PREEMPT_RT and avoids a 'select' statement on an option which has a 'depends' statement.
