[Qemu-devel] [PULL 1/7] mips: Remove CONFIG_VT82C686 from non-Fulong configs

[Leon Alrae]

From: "Maciej W. Rozycki" <macro@codesourcery.com>

Fix the regression introduced with commit
47934d0aadc075b05ce2d9e8a44fa6a46edd1afa [hw: move ISA bridges and
devices to hw/isa/, configure with default-configs/], by removing
CONFIG_VT82C686 from configurations that previously did not enable it.
That southbridge is only available on Fulong platforms (CONFIG_FULONG)
that are exclusively little-endian, 64-bit MIPS.  Previously vt82c686.o
was pulled explicitly with obj-$(CONFIG_FULONG).

[Qemu-devel] [PULL 2/7] mips: Respect CP0.Status.CU1 for microMIPS FP branches

[Leon Alrae]

From: "Maciej W. Rozycki" <macro@codesourcery.com>

Make microMIPS FP branches respect CP0.Status.CU1 and trap with a
Coprocessor Unusable exception if COP1 has been disabled; also trap if
no FPU is present at all.

Standard MIPS FP instruction encodings have a more regular structure and
branches are covered with a single umbrella along other instructions.
This is not the case with the microMIPS encoding, this case has to be
taken care of explicitly here.  Code to do so has been copied from the
standard MIPS code handler for OPC_CP1, in `decode_opc'.

Problems arising from this bug will generally only show up on user
context switches in operating systems making use of lazy FP context
switches, such as Linux.  It will also more readily trigger if software
FPU emulation is used, either implicitly on a non-float CPU, or forced
on a hard-float CPU such as with the "nofpu" Linux kernel command line
argument.

The problem may have been easily missed because we have no hard-float
microMIPS CPU configuration present; in fact we have no microMIPS CPU
configuration of any kind present.

[Qemu-devel] [PULL 4/7] mips: Set the CP0.Config3.DSP and CP0.Config3.DSP2P bits

[Leon Alrae]

From: "Maciej W. Rozycki" <macro@codesourcery.com>

Set the CP0.Config3.DSP2P bit for the 74kf processor and both that bit
and the CP0.Config3.DSP bit for the artificial mips32r5-generic and
mips64dspr2 processors.  They have the DSPr2 ASE enabled in `insn_flags'
and CPUs that implement that ASE need to have both CP0.Config3.DSP and
CP0.Config3.DSP2P set or software won't detect its presence.

[Qemu-devel] [PULL 6/7] mips: Ensure PC update with MTC0 single-stepping

[Leon Alrae]

From: "Maciej W. Rozycki" <macro@codesourcery.com>

Correct the way PC is updated when single-stepping instructions, by
keeping the old PC only for the BS_EXCP (exception condition) state.

Some MTC0 (and possibly other) instructions switch to the BS_STOP state
to terminate the current translation block, so that the state transition
of the simulated CPU resulting from the CP0 operation takes effect with
the following instruction.  This happens with `mtc0 <reg>,c0_config' for
example, typically used to set KSEG0 cacheability.

While single-stepping this has a side-effect of not advancing the PC
past the instruction just executed; subsequent single-step traps will
stop at the same instruction repeatedly.  Example:

(gdb) stepi
0x80004d24 in _start ()
5: x/i $pc
=> 0x80004d24 <_start+364>:     mfc0    t1,c0_config
(gdb)
0x80004d28 in _start ()
5: x/i $pc
=> 0x80004d28 <_start+368>:     li      at,-8
(gdb)
0x80004d2c in _start ()
5: x/i $pc
=> 0x80004d2c <_start+372>:     and     t1,t1,at

PS: you might like to look at suppressing these relatively
new clang warnings:

target-mips/translate.c:1968:15: warning: no case matching constant
switch condition '16'
FOP_CONDNS(s, FMT_S, 32, gen_store_fpr32(fp0, fd))

target-mips/translate.c:1885:13: note: expanded from macro 'FOP_CONDNS'

            ^

That can wait for 2.3 though, we have plenty of other clang
warnings still and the code looks correct.
