| 1 | 2c52c816 | ths | Unsolved issues/bugs in the mips/mipsel backend |
|---|---|---|---|
| 2 | 2c52c816 | ths | ----------------------------------------------- |
| 3 | 2c52c816 | ths | |
| 4 | 15dcf5aa | ths | General |
| 5 | 15dcf5aa | ths | ------- |
| 6 | 2c52c816 | ths | - [ls][dw][lr] report broken (aligned) BadVAddr |
| 7 | 2c52c816 | ths | - Missing per-CPU instruction decoding, currently all implemented |
| 8 | 2c52c816 | ths | instructions are regarded as valid |
| 9 | 509b8ab2 | ths | - Applications running on top of a emulated Linux segfault sometimes |
| 10 | 509b8ab2 | ths | when the Qemu FPU emulation is disabled. This is apparently a qemu |
| 11 | 509b8ab2 | ths | bug triggered by the Linux in-kernel FPU emulator. |
| 12 | 509b8ab2 | ths | - The Timesys Linux installer shell hangs for e.g. "read foo". Likewise, |
| 13 | 509b8ab2 | ths | telnet'ting in the installer fails and hangs the telnetd. |
| 14 | 2c52c816 | ths | |
| 15 | 15dcf5aa | ths | MIPS64 |
| 16 | 15dcf5aa | ths | ------ |
| 17 | 15dcf5aa | ths | - No 64bit TLB support |
| 18 | 15dcf5aa | ths | - no 64bit wide registers for FPU |
| 19 | 15dcf5aa | ths | - 64bit mul/div handling broken |
| 20 | 15dcf5aa | ths | |
| 21 | 15dcf5aa | ths | "Generic" 4Kc system emulation |
| 22 | 15dcf5aa | ths | ------------------------------ |
| 23 | 15dcf5aa | ths | - Doesn't correspond to any real hardware. |
| 24 | 15dcf5aa | ths | |
| 25 | 509b8ab2 | ths | PICA 61 system emulation |
| 26 | 509b8ab2 | ths | ------------------------ |
| 27 | 509b8ab2 | ths | - No framebuffer support yet. |
| 28 | 509b8ab2 | ths | |
| 29 | 15dcf5aa | ths | MALTA system emulation |
| 30 | 15dcf5aa | ths | ---------------------- |
| 31 | 2c52c816 | ths | - We fake firmware support instead of doing the real thing |
| 32 | 4a109bfb | ths | - Real firmware falls over when trying to init RAM, presumably due |
| 33 | 7246bb21 | ths | to lacking system controller emulation. |
