| Unsolved issues/bugs in the mips/mipsel backend |
| ----------------------------------------------- |
| |
| General |
| ------- |
| - [ls][dw][lr] report broken (aligned) BadVAddr |
| - Missing per-CPU instruction decoding, currently all implemented |
| instructions are regarded as valid |
| - Applications running on top of a emulated Linux segfault sometimes |
| when the Qemu FPU emulation is disabled. This is apparently a qemu |
| bug triggered by the Linux in-kernel FPU emulator. |
| - The Timesys Linux installer shell hangs for e.g. "read foo". Likewise, |
| telnet'ting in the installer fails and hangs the telnetd. |
| |
| MIPS64 |
| ------ |
| - No 64bit TLB support |
| - no 64bit wide registers for FPU |
| - 64bit mul/div handling broken |
| |
| "Generic" 4Kc system emulation |
| ------------------------------ |
| - Doesn't correspond to any real hardware. |
| |
| PICA 61 system emulation |
| ------------------------ |
| - No framebuffer support yet. |
| |
| MALTA system emulation |
| ---------------------- |
| - We fake firmware support instead of doing the real thing |
| - Real firmware falls over when trying to init RAM, presumably due |
| to lacking system controller emulation. |
