Bernhard Beschow b01841fa85 accel/tcg: Inline dump_opcount_info() and remove it
dump_opcount_info() is a one-line wrapper around tcg_dump_op_count()
which is also exported. So use the latter directly.

Bernhard Beschow 7112ffd93a accel/tcg/cpu-exec: Unexport dump_drift_info()
Commit 3a841ab53f 'qapi: introduce
x-query-jit QMP command' basically moved the only function using
dump_drift_info() to cpu-exec.c. Therefore, dump_drift_info() doesn't
need to be exported any longer.

Peter Maydell 0c285e0128 hw/block/fdc-sysbus: Always mark sysbus floppy controllers as not having DMA
The sysbus floppy controllers (devices sysbus-fdc and sun-fdtwo)
don't support DMA.  The core floppy controller code expects this to
be indicated by setting FDCtrl::dma_chann to -1.  This used to be
done in the device instance_init functions sysbus_fdc_initfn() and
sun4m_fdc_initfn(), but in commit 1430759ec3 we refactored this code
and accidentally lost the setting of dma_chann.

For sysbus-fdc this has no ill effects because we were redundantly
also setting dma_chann in fdctrl_init_sysbus(), but for sun-fdtwo
this means that guests which try to enable DMA on the floppy
controller will cause QEMU to crash because FDCtrl::dma is NULL.

Set dma_chann to -1 in the common instance init, and remove the
redundant code in fdctrl_init_sysbus() that is also setting it.

There is a six-year-old FIXME comment in the jazz board code to the
effect that in theory it should support doing DMA via a custom DMA
controller.  If anybody ever chooses to fix that they can do it by
adding support for setting both FDCtrl::dma_chann and FDCtrl::dma.
(A QOM link property 'dma-controller' on the sysbus device which can
be set to an instance of IsaDmaClass is probably the way to go.)

nanoMIPS ISA support in QEMU is actively used by MediaTek and is
planned to be maintained and potentially extended by MediaTek in
future.

Un-orphan nanoMIPS ISA support in QEMU by setting a maintainer from
MediaTek and remove deprecation notes from documentation as well.

Stefan Pejic f1663114df target/mips: Add missing default cases for some nanoMIPS pools
Switch statements for the code segments that handle nanoMIPS
instruction pools P.LL, P.SC, P.SHIFT, P.LS.S1, P.LS.E0, PP.LSXS
do not have proper default case, resulting in not generating
reserved instruction exception for certain illegal opcodes.

Fix this by adding default cases for these switch statements that
trigger reserved instruction exception.

If both rs and rt are the same register, the nanoMIPS instruction
BNEC[32] rs, rt, address is equivalent to NOP (branch is not taken and
there is no delay slot). This commit provides such behavior. Without

Dragan Mladjenovic 5de4359b4f target/mips: Fix emulation of nanoMIPS BPOSGE32C instruction
There are currently two problems related to the emulation of the
instruction BPOSGE32C.

The nanoMIPS instruction BPOSGE32C belongs to DSP R3 instructions
(actually, as of now, it is the only instruction of DSP R3). The
presence of DSP R3 instructions in QEMU is indicated by the flag
MIPS_HFLAG_DSP_R3 (0x20000000). This flag is currently being properly
set in CPUMIPSState's hflags (for example, for I7200 nanoMIPS CPU).
However, it is not propagated to DisasContext's hflags, since the flag
MIPS_HFLAG_DSP_R3 is not set in MIPS_HFLAG_TMASK (while similar flags
MIPS_HFLAG_DSP_R2 and MIPS_HFLAG_DSP are set in this mask, and there
is no problem in functioning check_dsp_r2(), check_dsp()). This means
the function check_dsp_r3() currently does not work properly, and the
emulation of BPOSGE32C can not work properly as well.

Change MIPS_HFLAG_TMASK from 0x1F5807FF to 0x3F5807FF (logical OR
with 0x20000000) to fix this.

Additionally, check_cp1_enabled() is currently incorrectly called
while emulating BPOSGE32C. BPOSGE32C is in the same pool (P.BR1) as
FPU branch instruction BC1EQZC and BC1NEZC, but it not a part of FPU
(CP1) instructions, and check_cp1_enabled() should not be involved
while emulating BPOSGE32C.

Rearrange invocations of check_cp1_enabled() within P.BR1 pool
handling to affect only BC1EQZC and BC1NEZC emulation, and not
BPOSGE32C emulation.

Dragan Mladjenovic 9e4f726d4f target/mips: Fix emulation of nanoMIPS EXTRV_S.H instruction
The field rs in the instruction EXTRV_S.H rt, ac, rs is specified in
nanoMIPS documentation as opcode[20..16]. It is, however, erroneously
considered as opcode[25..21] in the current QEMU implementation. In
function gen_pool32axf_2_nanomips_insn(), the variable v0_t corresponds
to rt/opcode[25..21], and v1_t corresponds to rs/opcode[20..16]), and
v0_t is by mistake passed to the helper gen_helper_extr_s_h().

Use v1_t rather than v0_t in the invocation of gen_helper_extr_s_h()
to fix this.
