| 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. Also gdb inside the emulated |
| system does not work. Both problems are caused by insufficient |
| handling of self-modifying code. |
| - Floating point exception emulation is incomplete. |
| |
| MIPS64 |
| ------ |
| - No 64bit TLB support |
| - 64bit FPU not fully implemented |
| - 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. |
