Richard Henderson f0655423ca target/openrisc: Reorg tlb lookup
While openrisc has a split i/d tlb, qemu does not.  Perform a
lookup on both i & d tlbs in parallel and put the composite
rights into qemu's tlb.  This avoids ping-ponging the qemu tlb
between EXEC and READ.

Richard Henderson 1cc9e5d896 target/openrisc: Increase the TLB size
The architecture supports 128 TLB entries.  There is no reason
not to provide all of them.  In the process we need to fix a
bug that failed to parameterize the configuration register that
tells the operating system the number of entries.

Richard Henderson b9bed1b9ab target/openrisc: Fix cpu_mmu_index
The code in cpu_mmu_index does not properly honor SR_DME.
This bug has workarounds elsewhere in that we flush the
tlb more often than necessary, on the state changes that
should be reflected in a change of mmu_index.

Fixing this means that we can respect the mmu_index that
is given to tlb_flush.

Richard Henderson fffde6695f target/openrisc: Fix tlb flushing in mtspr
The previous code was confused, avoiding the flush of the old entry
if the new entry is invalid.  We need to flush the old page if the
old entry is valid and the new page if the new entry is valid.

This bug was masked by over-flushing elsewhere.

Richard Henderson 455d45d22c target/openrisc: Merge tlb allocation into CPUOpenRISCState
There is no reason to allocate this separately.  This was probably
copied from target/mips which makes the same mistake.

While doing so, move tlb into the clear-on-reset range.  While not
all of the TLB bits are guaranteed zero on reset, all of the valid
bits are cleared, and the rest of the bits are unspecified.
Therefore clearing the whole of the TLB is correct.

Peter Maydell 0f02251a30 xtensa: Avoid calling get_page_addr_code() from helper function
The xtensa frontend calls get_page_addr_code() from its
itlb_hit_test helper function. This function is really part
of the TCG core's internals, and calling it from a target
helper makes it awkward to make changes to that core code.
It also means that we don't pass the correct retaddr to
tlb_fill(), so we won't correctly handle the case where
an exception is generated.

The helper is used for the instructions IHI, IHU and IPFL.

Change it to call cpu_ldb_code_ra() instead.

Peter Xu c73a843b4a monitor: flush qmp responses when CLOSED
Previously we clean up the queues when we got CLOSED event.  It was used
to make sure we won't send leftover replies/events of a old client to a
new client which makes perfect sense. However this will also drop the
replies/events even if the output port of the previous chardev backend
is still open, which can lead to missing of the last replies/events.
Now this patch does an extra operation to flush the response queue
before cleaning up.

In most cases, a QMP session will be based on a bidirectional channel (a
TCP port, for example, we read/write to the same socket handle), so in
port and out port of the backend chardev are fundamentally the same
port. In these cases, it does not really matter much on whether we'll
flush the response queue since flushing will fail anyway.  However there
can be cases where in & out ports of the QMP monitor's backend chardev
are separated.  Here is an example:

  cat $QMP_COMMANDS | qemu -qmp stdio ... | filter_commands

In this case, the backend is fd-typed, and it is connected to stdio
where in port is stdin and out port is stdout.  Now if we drop all the
events on the response queue then filter_command process might miss some
events that it might expect.  The thing is that, when stdin closes,
stdout might still be there alive!

In practice, I encountered SHUTDOWN event missing when running test with
iotest 087 with Out-Of-Band enabled.  Here is one of the ways that this
can happen (after "quit" command is executed and QEMU quits the main
loop):

1. [main thread] QEMU queues a SHUTDOWN event into response queue.

2. "cat" terminates (to distinguish it from the animal, I quote it).

3. [monitor iothread] QEMU's monitor iothread reads EOF from stdin.

4. [monitor iothread] QEMU's monitor iothread calls the CLOSED event
   hook for the monitor, which will destroy the response queue of the
   monitor, then the SHUTDOWN event is dropped.

5. [main thread] QEMU's main thread cleans up the monitors in
   monitor_cleanup().  When trying to flush pending responses, it sees
   nothing.  SHUTDOWN is lost forever.

Note that before the monitor iothread was introduced, step [4]/[5] could
never happen since the main loop was the only place to detect the EOF
event of stdin and run the CLOSED event hooks.  Now things can happen in
parallel in the iothread.

Peter Xu 40687eb741 monitor: rename *_pop_one to *_pop_any
The old names are confusing since both of the old functions are popping
an item from multiple queues rather than a single queue.  In that
sense, *_pop_any() suites better than *_pop_one().

Since at it, touch up the function monitor_qmp_response_pop_any() a bit
to let the callers pass in a QMPResponse struct instead of returning a
struct.  Change the return value to boolean to mark whether we have
popped a valid response instead.

Peter Maydell 13606b9951 sd: Don't trace SDRequest crc field
We don't actually implement SD command CRC checking, because
for almost all of our SD controllers the CRC generation is
done in hardware, and so modelling CRC generation and checking
would be a bit pointless. (The exception is that milkymist-memcard
makes the guest software compute the CRC.)

As a result almost all of our SD controller models don't bother
to set the SDRequest crc field, and the SD card model doesn't
check it. So the tracing of it in sdbus_do_command() provokes
Coverity warnings about use of uninitialized data.

Drop the CRC field from the trace; we can always add it back
if and when we do anything useful with the CRC.

Fixes Coverity issues 1386072, 1386074, 1386076, 1390571.
