905db98a73 accel/tcg: Check for USER_ONLY definition instead of SOFTMMU one
Since we *might* have user emulation with softmmu,
replace the system emulation check by !user emulation one.

Invert some if() ladders for clarity.

bd96e10071 imx_serial: set wake bit when we receive a data byte
The Linux kernel added a flood check for RX data recently in commit
496a4471b7c3 ("serial: imx: work-around for hardware RX flood"). This
check uses the wake bit in the UART status register 2. The wake bit
indicates that the receiver detected a start bit on the RX line. If the
kernel sees a number of RX interrupts without the wake bit being set, it
treats this as spurious data and resets the UART port. imx_serial does
never set the wake bit and triggers the kernel's flood check.

This patch adds support for the wake bit. wake is set when we receive a
new character (it's not set for break events). It seems that wake is
cleared by the kernel driver, the hardware does not have to clear it
automatically after data was read.

The wake bit can be configured as an interrupt source. Support this
mechanism as well.

d2f9a79a8c hw/timer/nrf51_timer: Don't lose time when timer is queried in tight loop
The nrf51_timer has a free-running counter which we implement using
the pattern of using two fields (update_counter_ns, counter) to track
the last point at which we calculated the counter value, and the
counter value at that time.  Then we can find the current counter
value by converting the difference in wall-clock time between then
and now to a tick count that we need to add to the counter value.

Unfortunately the nrf51_timer's implementation of this has a bug
which means it loses time every time update_counter() is called.
After updating s->counter it always sets s->update_counter_ns to
'now', even though the actual point when s->counter hit the new value
will be some point in the past (half a tick, say).  In the worst case
(guest code in a tight loop reading the counter, icount mode) the
counter is continually queried less than a tick after it was last
read, so s->counter never advances but s->update_counter_ns does, and
the guest never makes forward progress.

The fix for this is to only advance update_counter_ns to the
timestamp of the last tick, not all the way to 'now'.  (This is the
pattern used in hw/misc/mps2-fpgaio.c's counter.)

22c81783c9 hw/sd/allwinner-sdhost: Don't send non-boolean IRQ line levels
QEMU allows qemu_irq lines to transfer arbitrary integers.  However
the convention is that for a simple IRQ line the values transferred
are always 0 and 1.  The A10 SD controller device instead assumes a
0-vs-non-0 convention, which happens to work with the interrupt
controller it is wired up to.

Coerce the value to boolean to follow our usual convention.

f837b468cd hw/intc/allwinner-a10-pic: Handle IRQ levels other than 0 or 1
In commit 2c5fa0778c we fixed an endianness bug in the Allwinner
A10 PIC model; however in the process we introduced a regression.
This is because the old code was robust against the incoming 'level'
argument being something other than 0 or 1, whereas the new code was
not.

In particular, the allwinner-sdhost code treats its IRQ line
as 0-vs-non-0 rather than 0-vs-1, so when the SD controller
set its IRQ line for any reason other than transmit the
interrupt controller would ignore it. The observed effect
was a guest timeout when rebooting the guest kernel.

Handle level values other than 0 or 1, to restore the old
behaviour.

Convert the instructions in the load/store exclusive (STXR,

Note that for STLR, STLLR, LDAR, LDLAR this fixes an under-decoding
in the legacy decoder where we were not checking that the RES1 bits
in the Rs and Rt2 fields were set.

The new function ldst_iss_sf() is equivalent to the existing
disas_ldst_compute_iss_sf(), but it takes the pre-decoded 'ext' field
rather than taking an undecoded two-bit opc field and extracting
'ext' from it. Once all the loads and stores have been converted
to decodetree disas_ldst_compute_iss_sf() will be unused and
can be deleted.

For the disas_ldst_single_struct() and disas_ldst_multiple_struct()

allocation tags are enabled, but didn't get it right when ATA=0:
instead of merging the tag bits into Xt, we merged them into the

243705aa6e target/arm: Fix return value from LDSMIN/LDSMAX 8/16 bit atomics
The atomic memory operations are supposed to return the old memory
data value in the destination register.  This value is not
sign-extended, even if the operation is the signed minimum or
maximum.  (In the pseudocode for the instructions the returned data
value is passed to ZeroExtend() to create the value in the register.)

We got this wrong because we were doing a 32-to-64 zero extend on the
result for 8 and 16 bit data values, rather than the correct amount
of zero extension.

Fix the bug by using ext8u and ext16u for the MO_8 and MO_16 data
sizes rather than ext32u.
