sdlaudio: fill remaining sample buffer with silence
Fill the remaining sample buffer with silence. To fill it with

Commit
bcf19777df: "audio/sdlaudio: Allow audio playback with

Add an out.buffer-count option to give users a chance to select

identical PWM modules. Each module contains 4 PWM entries. Each PWM has
two outputs: frequency and duty_cycle. Both are computed using inputs
from software side.
This module does not model detail pulse signals since it is expensive.
It also does not model interrupts and watchdogs that are dependant on
the detail models. The interfaces for these are left in the module so
that anyone in need for these functionalities can implement on their
own.
The user can read the duty cycle and frequency using qom-get command.

converter in NPCM7XX CLK Module(PLL, SEL or Divider). Each converter
takes one or more input clocks and converts them into one output clock.
They form a clock hierarchy in the CLK module and are responsible for
outputing clocks for various other modules in an NPCM7XX SoC.
Each converter has a function pointer called "convert" which represents
the unique logic for that converter.
The clock contains two initialization information: ConverterInitInfo and
ConverterConnectionInfo. They represent the vertices and edges in the

In commit
cd8be50e58f63413c0 we converted the A32 coprocessor
insns to decodetree. This accidentally broke XScale/iWMMXt insns,
because it moved the handling of "cp insns which are handled
by looking up the cp register in the hashtable" from after the
call to the legacy disas_xscale_insn() decode to before it,
with the result that all XScale/iWMMXt insns now UNDEF.
Update valid_cp() so that it knows that on XScale cp 0 and 1
are not standard coprocessor instructions; this will cause
the decodetree trans_ functions to ignore them, so that
execution will correctly get through to the legacy decode again.

The code that dumps the stack frame works like that:
* save current registers
* overwrite current registers (including rip/rsp) with coroutine snapshot
in the jmpbuf
* print backtrace
* restore the saved registers.
If the user has currently selected a non topmost stack frame in gdb,
the above code will still restore the selected frame registers,
but the gdb will then lose the selected frame index, which makes it impossible
to switch back to frame 0, to continue debugging the executable.
Therefore switch temporarily to the topmost frame of the stack

added significant overhead, since the fuzzer needs to map all the

There was a race condition in the first test where there was already the
"crw" output in the dmesg, but the "0.0.4711" entry has not been created
in the /sys fs yet. Fix it by waiting until it is there.
The second test has even more problems on gitlab-CI. Even after adding some
more synchronization points (that wait for some messages in the "dmesg"
output to make sure that the modules got loaded correctly), there are still
occasionally some hangs in this test when it is running in the gitlab-CI.
So far I was unable to reproduce these hangs locally on my computer, so
this issue might take a while to debug. Thus disable the 2nd test in the
gitlab-CI until the problems are better understood and fixed.

fuzz: remove IO commands iteratively
Now we use a one-time scan and remove strategy in the minimizer,
which is not suitable for timing dependent instructions.
For example, instruction A will indicate an address where the config
chunk locates, and instruction B will make the configuration active.
If we have the following instruction sequence:
...
A1
B1
A2
B2
...
A2 and B2 are the actual instructions that trigger the bug.
If we scan from top to bottom, after we remove A1, the behavior of B1
might be unknowable, including not to crash the program. But we will
successfully remove B1 later cause A2 and B2 will crash the process
anyway:
...
A1
A2
B2
...
Now one more trimming will remove A1.
In the perfect case, we would need to be able to remove A and B (or C!) at
the same time. But for now, let's just add a loop around the minimizer.
Since we only remove instructions, this iterative algorithm is converging.

fuzz: split write operand using binary approach
Currently, we split the write commands' data from the middle. If it does not
work, try to move the pivot left by one byte and retry until there is no
space.
But, this method has two flaws:
1. It may fail to trim all unnecessary bytes on the right side.
For example, there is an IO write command:
write addr uuxxxxuu
u is the unnecessary byte for the crash. Unlike ram write commands, in most
case, a split IO write won't trigger the same crash, So if we split from the
middle, we will get:
write addr uu (will be removed in next round)
write addr xxxxuu
For xxxxuu, since split it from the middle and retry to the leftmost byte
won't get the same crash, we will be stopped from removing the last two
bytes.
2. The algorithm complexity is O(n) since we move the pivot byte by byte.
To solve the first issue, we can try a symmetrical position on the right if
we fail on the left. As for the second issue, instead moving by one byte, we
can approach the boundary exponentially, achieving O(log(n)).
Give an example:
xxxxuu len=6
+
|
+
xxx,xuu 6/2=3 fail
+
+--------------+-------------+
| |
+ +
xx,xxuu 6/2^2=1 fail xxxxu,u 6-1=5 success
+ +
+------------------+----+ |
| | +-------------+ u removed
+ +
xx,xxu 5/2=2 fail xxxx,u 6-2=4 success
+
|
+-----------+ u removed
In some rare cases, this algorithm will fail to trim all unnecessary bytes:
xxxxxxxxxuxxxxxx
xxxxxxxx-xuxxxxxx Fail
xxxx-xxxxxuxxxxxx Fail
xxxxxxxxxuxx-xxxx Fail
...
I think the trade-off is worth it.

fuzz: double the IOs to remove for every loop
Instead of removing IO instructions one by one, we can try deleting multiple
instructions at once. According to the locality of reference, we double the
number of instructions to remove for the next round and recover it to one

hw/arm: sabrelite: Connect the Ethernet PHY at address 6
At present, when booting U-Boot on QEMU sabrelite, we see:
Net: Board Net Initialization Failed
No ethernet found.
U-Boot scans PHY at address 4/5/6/7 (see board_eth_init() in the
U-Boot source: board/boundary/nitrogen6x/nitrogen6x.c). On the real
board, the Ethernet PHY is at address 6. Adjust this by updating the
"fec-phy-num" property of the fsl_imx6 SoC object.
With this change, U-Boot sees the PHY but complains MAC address:
Net: using phy at 6
FEC [PRIME]
Error: FEC address not set.
This is due to U-Boot tries to read the MAC address from the fuse,
which QEMU does not have any valid content filled in. However this
does not prevent the Ethernet from working in QEMU. We just need to
set up the MAC address later in the U-Boot command shell, by:
=> setenv ethaddr 00:11:22:33:44:55

util/qemu-timer: Make timer_free() imply timer_del()
Currently timer_free() is a simple wrapper for g_free(). This means
that the timer being freed must not be currently active, as otherwise
QEMU might crash later when the active list is processed and still
has a pointer to freed memory on it. As a result almost all calls to
timer_free() are preceded by a timer_del() call, as can be seen in
the output of
git grep -B1 '\<timer_free\>'
This is unfortunate API design as it makes it easy to accidentally
misuse (by forgetting the timer_del()), and the correct use is
annoyingly verbose.
Make timer_free() imply a timer_del().

Support for running KVM on 32-bit Arm hosts was removed in commit
82bf7ae84ce739e. You can still run a 32-bit guest on a 64-bit Arm
host CPU, but because Arm KVM requires the host and guest CPU types
to match, it is not possible to run a guest that requires a Cortex-A9

target/arm: Correct store of FPSCR value via FPCXT_S
In commit
64f863baeedc8659 we implemented the v8.1M FPCXT_S register,
but we got the write behaviour wrong. On read, this register reads
bits [27:0] of FPSCR plus the CONTROL.SFPA bit. On write, it doesn't
just write back those bits -- it writes a value to the whole FPSCR,
whose upper 4 bits are zeroes.
We also incorrectly implemented the write-to-FPSCR as a simple store
to vfp.xregs; this skips the "update the softfloat flags" part of
the vfp_set_fpscr helper so the value would read back correctly but
not actually take effect.
Fix both of these things by doing a complete write to the FPSCR
using the helper function.
