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
|
|
- pcnet32 does not work for little endian emulation on big endian host
|
|
(probably not mips specific, but observable for mips-malta)
|
|
|
|
MIPS64
|
|
------
|
|
- No 64bit TLB support
|
|
- no 64bit wide registers for FPU
|
|
- 64bit mul/div handling broken
|
|
- DM[FT]C not implemented, M[FT]C does not cut sign extensions in all
|
|
cases.
|
|
|
|
"Generic" 4Kc system emulation
|
|
------------------------------
|
|
- Doesn't correspond to any real hardware.
|
|
|
|
MALTA system emulation
|
|
----------------------
|
|
- We fake firmware support instead of doing the real thing
|
|
- Linux 2.4/2.6 Kernels receive spurious PIIX4 interrupts, noisy on 2.4,
|
|
silent on 2.6, indicates some divergence from actual hardware.
