Upstream a long-standing OpenWrt patch [0] that fixes MT7620 PCIe PLL lock check. The existing code checks the wrong register bit: PPLL_SW_SET is not defined in PPLL_CFG1 and bit 31 of PPLL_CFG1 is marked as reserved in the MT7620 Programming Guide. The correct bit to check for PLL lock is PPLL_LD (bit 23). Also reword the error message for clarity. Without this change it is unlikely that this driver ever worked with mainline kernel.

2021-03-10MIPS: Enable some missed configs in loongson3_defconfig to support bpftraceTiezhu Yang1-1/+6
bpftrace is a high-level tracing language for Linux enhanced Berkeley Packet Filter (eBPF) available in recent Linux kernels (4.x). bpftrace uses LLVM as a backend to compile scripts to BPF-bytecode and makes use of BCC for interacting with the Linux BPF system, as well as existing Linux tracing capabilities: kernel dynamic tracing (kprobes), user-level dynamic tracing (uprobes), and tracepoints. According to Linux Kernel Requirements in bpftrace/INSTALL.md [1], the kernel needs to be built with the following options: CONFIG_BPF=y CONFIG_BPF_SYSCALL=y CONFIG_BPF_JIT=y CONFIG_HAVE_EBPF_JIT=y CONFIG_BPF_EVENTS=y CONFIG_FTRACE_SYSCALLS=y CONFIG_FUNCTION_TRACER=y CONFIG_HAVE_DYNAMIC_FTRACE=y CONFIG_DYNAMIC_FTRACE=y CONFIG_HAVE_KPROBES=y CONFIG_KPROBES=y CONFIG_KPROBE_EVENTS=y CONFIG_ARCH_SUPPORTS_UPROBES=y CONFIG_UPROBES=y CONFIG_UPROBE_EVENTS=y CONFIG_DEBUG_FS=y So enable some missed configs in loongson3_defconfig to make sure the above configs are set after make loongson3_defconfig.

Many architectures duplicate similar shell scripts. This commit converts mips to use scripts/syscalltbl.sh. This also unifies syscall_table_32_o32.h and syscall_table_64_o32.h into syscall_table_o32.h. The offset parameters are unneeded here; __SYSCALL(nr, entry) is defined as 'PTR entry', so the parameter 'nr' is not used in the first place. With this commit, syscall tables and generated files are straight mapped, which makes things easier to understand. syscall_n32.tbl --> syscall_table_n32.h syscall_n64.tbl --> syscall_table_n64.h syscall_o32.tbl --> syscall_table_o32.h Then, the abi parameters are also unneeded.

2021-03-09MIPS: kernel: Reserve exception base early to prevent corruptionThomas Bogendoerfer4-5/+17
BMIPS is one of the few platforms that do change the exception base. After commit 2dcb39645441 ("memblock: do not start bottom-up allocations with kernel_end") we started seeing BMIPS boards fail to boot with the built-in FDT being corrupted. Before the cited commit, early allocations would be in the [kernel_end, RAM_END] range, but after commit they would be within [RAM_START + PAGE_SIZE, RAM_END]. The custom exception base handler that is installed by bmips_ebase_setup() done for BMIPS5000 CPUs ends-up trampling on the memory region allocated by unflatten_and_copy_device_tree() thus corrupting the FDT used by the kernel. To fix this, we need to perform an early reservation of the custom exception space. Additional we reserve the first 4k (1k for R3k) for either normal exception vector space (legacy CPUs) or special vectors like cache exceptions. Huge thanks to Serge for analysing and proposing a solution to this issue.

2021-03-08MIPS: vmlinux.lds.S: align raw appended dtb to 8 bytesBjørn Mork1-1/+5
The devicetree specification requires 8-byte alignment in memory. This is now enforced by libfdt since commit 79edff12060f ("scripts/dtc: Update to upstream version v1.6.0-51-g183df9e9c2b9") which included the upstream commit 5e735860c478 ("libfdt: Check for 8-byte address alignment in fdt_ro_probe_()"). This broke the MIPS raw appended DTBs which would be appended to the image immediately following the initramfs section. This ends with a 32bit size, resulting in a 4-byte alignment of the DTB. Fix by padding with zeroes to 8-bytes when MIPS_RAW_APPENDED_DTB is defined.
