In the current code, arch_has_single_step() is not defined on MIPS, that means MIPS does not support instruction single-step for user mode. Delve is a debugger for the Go programming language, the ptrace syscall PtraceSingleStep() failed [1] on MIPS and then the single step function can not work well, we can see that PtraceSingleStep() definition returns ptrace(PTRACE_SINGLESTEP) [2]. So it is necessary to support ptrace single step on MIPS. At the beginning, we try to use the Debug Single Step exception on the Loongson 3A4000 platform, but it has no effect when set CP0_DEBUG SSt bit, this is because CP0_DEBUG NoSSt bit is 1 which indicates no single-step feature available [3], so this way which is dependent on the hardware is almost impossible. With further research, we find out there exists a common way used with break instruction in arch/alpha/kernel/ptrace.c, it is workable. For the above analysis, define arch_has_single_step(), add the common function user_enable_single_step() and user_disable_single_step(), set flag TIF_SINGLESTEP for child process, use break instruction to set breakpoint. We can use the following testcase to test it: tools/testing/selftests/breakpoints/step_after_suspend_test.c $ make -C tools/testing/selftests TARGETS=breakpoints $ cd tools/testing/selftests/breakpoints Without this patch: $ ./step_after_suspend_test -n TAP version 13 1..4 # ptrace(PTRACE_SINGLESTEP) not supported on this architecture: Input/output error ok 1 # SKIP CPU 0 # ptrace(PTRACE_SINGLESTEP) not supported on this architecture: Input/output error ok 2 # SKIP CPU 1 # ptrace(PTRACE_SINGLESTEP) not supported on this architecture: Input/output error ok 3 # SKIP CPU 2 # ptrace(PTRACE_SINGLESTEP) not supported on this architecture: Input/output error ok 4 # SKIP CPU 3 # Totals: pass:0 fail:0 xfail:0 xpass:0 skip:4 error:0 With this patch: $ ./step_after_suspend_test -n TAP version 13 1..4 ok 1 CPU 0 ok 2 CPU 1 ok 3 CPU 2 ok 4 CPU 3 # Totals: pass:4 fail:0 xfail:0 xpass:0 skip:0 error:0 [1] https://github.com/go-delve/delve/blob/master/pkg/proc/native/threads_linux.go#L50 [2] https://github.com/go-delve/delve/blob/master/vendor/golang.org/x/sys/unix/syscall_linux.go#L1573 [3] http://www.t-es-t.hu/download/mips/md00047f.pdf Reported-by:

Commit ffe1f935 ("MAINTAINERS: Add Loongson-2/Loongson-3 maintainers") adds quite generic file entries for drivers/*/*loongson{2,3}* and drivers/*/*/*loongson{2,3}* to be informed on changes to all loongson{2,3} files in drivers. However, only the pattern 'drivers/*/*loongson2*' matches to one file in the repository, i.e., drivers/cpufreq/loongson2_cpufreq.c; all other patterns have no file matches. Hence, ./scripts/get_maintainer.pl --self-test=patterns complains: warning: no file matches F: drivers/*/*/*loongson2* warning: no file matches F: drivers/*/*/*loongson3* warning: no file matches F: drivers/*/*loongson3* As in the last two and half years, no further files and drivers have showed up to match those patterns, just name the one file that matches explicitly and delete the others without a match.

According to MIPS EJTAG Specification [1], a Debug Breakpoint exception occurs when an SDBBP instruction is executed, the CP0_DEBUG bit DBp indicates that a Debug Breakpoint exception occurred. When I read the original code, it looks a little confusing at first glance, just check bit DBp for SDBBP to make the code more readable, it will be much easier to understand.

This reverts commit 3751cbda. Originally the patch was created to fix the reserved-memory DT-node parsing failure on the early stages of the platform memory initialization. That happened due to the two early memory allocators utilization that time: bootmem and memblock. At first the platform-specific memory mapping array was initialized. Then the early_init_fdt_scan_reserved_mem() was called, which couldn't fully parse the "reserved-memory" DT-node since neither memblock nor bootmem allocators hadn't been initialized at that stage, so the fdt_init_reserved_mem() method failed on the memory allocation calls. Only after that the platform-specific memory mapping were used to create proper bootmem and memblock structures and let the early memory allocations work. That's why we had to call the fdt_init_reserved_mem() method one more time to retry the initialization of the features like CMA. The necessity to have that fix was disappeared after the full memblock support had been added to the MIPS kernel and all plat_mem_setup() had been fixed to add the memory regions right into the memblock memory pool. Let's revert that patch then especially after having Paul reported that the second fdt_init_reserved_mem() call causes the reserved memory pool being created twice bigger than implied.

The RTL838x/839x family of SoCs are Realtek switches with an embedded MIPS core. * RTL838x - 500MHz 4kce single core - 1Gbit ports and L2 features * RTL839x - 700MHz 34Kc single core - 1Gbit ports and L2 features These switches, depending on the exact part number, will have anywhere between 8 and 52 ports. The MIPS core is wired to a switch cpu port which has a tagging feature allowing us to make use of the DSA subsystem. The SoCs are somewhat basic in certain areas, getting better with more advanced features on newer series. The switch functionality is MMIO-mapped via a large MFD region. The SoCs have the following peripherals * ethernet * switch * uart - ns16550a * spi-flash interface * gpio * wdt * led The code was derived from various vendor SDKs based on Linux v2.6 kernels. This patchset allows us to boot RTL838x/RTL839x units with basic support. Most of the other drivers are already written and functional, and work to get them upstream is already in progress.

Reset lines with indices smaller than 8 are currently considered invalid by the rt2880-reset reset controller. The MT7621 SoC uses a number of these low reset lines. The DTS defines reset lines "hsdma", "fe", and "mcm" with respective values 5, 6, and 2. As a result of the above restriction, these resets cannot be asserted or de-asserted by the reset controller. In cases where the bootloader does not de-assert these lines, this results in e.g. the MT7621's internal switch staying in reset. Change the reset controller to only ignore the system reset, so all reset lines with index greater than 0 are considered valid. Signed-off-by:

For those leaf functions, they are likely to have no stack operations. Add is_jr_ra_ins() to determine whether jr ra has been touched before the frame_size is found. Without this patch, the get frame_size operation may be out of range and get the frame_size from the next nested function. There is no POOL32A format in uapi/asm/inst.h, so some bits here use the format of r_format instead. e.g. --------------------------------------------------------------------- | format | 31:26 | 25:21 | 20:16 | 15:6 | 5:0 | -----------------+---------+-------+-------+------------+------------ | pool32a_format | pool32a | rt | rs | jalrc | pool32axf | -----------------+---------+-------+-------+------------+------------ | r_format | opcode | rs | rt | rd:5, re:5 | func | --------------------------------------------------------------------- Signed-off-by:

Second patch fixed the situation that info->func_size is zero. However, func_size member became useless after the second commit. Without ip_end, the get frame_size operation may be out of range although KALLSYMS enabled. Thus, check func_size first. Then make ip_end be the sum of ip and a constant (512) if func_size is equal to 0. Otherwise make ip_end be the sum of ip and func_size. Signed-off-by:
