| 2024-04-23 | Implementation of riscv_hwprobe syscall from Linux (#325) | Wojciech Muła | 1 | -0/+51 | |
| See: https://www.kernel.org/doc/html/latest/arch/riscv/hwprobe.html | |||||
| 2024-03-22 | Implement syscall readlinkat and readv (#318) | mylai-mtk | 1 | -0/+87 | |
| * Implement syscall readlinkat * Implement syscall readv by read syscalls Since pk lacks kernel-space dynamic memory management, we implement readv with normal read syscalls rather than forwarding it to spike | |||||
| 2022-04-30 | Fix a file leak in function `at_kfd` (#276) | MaxXing | 1 | -1/+3 | |
| 2022-04-11 | Handle unimplemented syscalls gracefully | Andrew Waterman | 1 | -11/+1 | |
| We previously kernel-panicked because that made it more obvious when a syscall implementation was missing. These days, it's more common that the C library will do something sensible in response to returning -ENOSYS. Favor that approach to avoid frustrating users. | |||||
| 2022-04-08 | Stub out sysinfo syscall | Andrew Waterman | 1 | -0/+1 | |
| 2022-01-09 | fix file leak | Andrew Waterman | 1 | -1/+1 | |
| Eliminate excess reference count when associating fd with file. Fixes #258 | |||||
| 2021-08-27 | pk: correct the handling of SYS_getcwd (#250) | Saleem Abdulrasool | 1 | -1/+1 | |
| `SYS_getcwd` is different from `getcwd` in that the return value is < 0 on failure otherwise it is the length of the string. The proxy kernel was treating 0 as success and all other values as error. As a result, we would never return a valid value for `getcwd`. The following program now executes properly with the Proxy Kernel: ```c #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <linux/limits.h> int main(int argc, char **argv) { unsigned char buffer[PATH_MAX + 1] = {0}; if (getcwd(buffer, PATH_MAX)) printf("cwd: %s\n", buffer); return EXIT_SUCCESS; } ``` | |||||
| 2021-03-25 | pk: support >2 GiB of user memory for RV64 | Andrew Waterman | 1 | -0/+2 | |
| Previously, the pk would always run from virtual address MEM_START. Instead, remap it into the negative virtual addresses, allowing user processes to expand beyond MEM_START. | |||||
| 2021-03-25 | Add some missing syscall stubs | Andrew Waterman | 1 | -0/+8 | |
| 2021-03-25 | pk: only access user memory through explicit accessors | Andrew Waterman | 1 | -57/+177 | |
| Enforced with sstatus.SUM. | |||||
| 2021-03-25 | Add `statx` syscall (#234) | huaixv | 1 | -0/+20 | |
| 2020-11-29 | Remove use of copy_stat() from sys_fstat and sys_lstat (#228) | Marcus Comstedt | 1 | -2/+4 | |
| 2020-11-17 | Remove use of copy_stat() from sys_fstatat | Marcus Comstedt | 1 | -1/+1 | |
| The system call should return the stat struct in kernel format, not libc format. | |||||
| 2020-03-16 | Fix CPI calcualtion for -s option (#192) | davidmetz | 1 | -1/+1 | |
| This attempt at rounding leads to wrong results, for example: 314689951 cycles 314690101 instructions 0.90 CPI With my change results in: 314689951 cycles 314690101 instructions 0.99 CPI I think this was supposed to be part of rounding behaviour but it doesn't work if only the final digit does it and there is no carry... Instead I changed it to truncate after the second digit | |||||
| 2019-10-22 | Implement dup3 syscall (#162) | Luís Marques | 1 | -0/+16 | |
| 2019-10-22 | Make performance counters always 64 bits wide (#178) | Luís Marques | 1 | -12/+13 | |
| This prevents the counters from easily overflowing for a 32-bit pk. | |||||
| 2019-02-28 | Stub out madvise syscall (#145) | Luís Marques | 1 | -0/+1 | |
| 2019-01-04 | Implement clock_gettime syscall (#139) | Luís Marques | 1 | -1/+10 | |
| 2018-02-01 | Bump the Linux version PK claims to support | Andrew Waterman | 1 | -1/+1 | |
| This makes it more compatible with recent glibc. | |||||

| 2016-02-19 | Remove incorrect code supporting ELF32 on RV64 and vice-versa | Andrew Waterman | 1 | -34/+12 | |
| This is technically possible by running an RV32 supervisor on an RV64 machine, but the M-mode and S-mode code would need to be compiled and linked separately. | |||||
