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.

2021-03-10mips: syscalls: switch to generic syscalltbl.shMasahiro Yamada7-71/+17
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.

2021-03-10ARM: dts: Configure interconnect target module for omap5 sataTony Lindgren2-15/+25
We can now probe devices with device tree only configuration using ti-sysc interconnect target module driver. Let's configure the module, but keep the legacy "ti,hwmods" peroperty to avoid new boot time warnings. The legacy property will be removed in later patches together with the legacy platform data. Note that the old sysc register offset is wrong, the real offset is at 0x1100 as listed in TRM for SATA_SYSCONFIG register. Looks like we've been happily using sata on the bootloader configured sysconfig register and nobody noticed. Also the old register range for SATAMAC_wrapper registers is wrong at 7 while it should be 8. But that too seems harmless. There is also an L3 parent interconnect range that we don't seem to be using. That can be added as needed later on. Signed-off-by: Tony Lindgren <tony@atomide.com>
