[PULL 1/8] hw/audio/es1370: reset current sample counter

[marcandre.lureau]

From: Volker Rümelin <vr_qemu@t-online.de>

Reset the current sample counter when writing the Channel Sample
Count Register. The Linux ens1370 driver and the AROS sb128
driver expect the current sample counter counts down from sample
count to 0 after a write to the Channel Sample Count Register.
Currently the current sample counter starts from 0 after a reset
or the last count when the counter was stopped.

The current sample counter is used to raise an interrupt whenever
a complete buffer was transferred. When the counter starts with a
value lower than the reload value, the interrupt triggeres before
the buffer was completly transferred. This may lead to corrupted
audio streams.

[PULL 2/8] hw/audio/es1370: replace bit-rotted code with tracepoints

[marcandre.lureau]

From: Volker Rümelin <vr_qemu@t-online.de>

It seems that nobody has enabled the debug code of the ES1370
device for a long time. Since then, the code has bit-rotted.
Replace the bit-rotten code with tracepoints.

[PULL 3/8] hw/audio/es1370: remove unused dolog macro

[marcandre.lureau]

From: Volker Rümelin <vr_qemu@t-online.de>

The dolog macro is unused. Remove the macro and use the now unused
ES1370_VERBOSE macro to replace its inverse ES1370_SILENT macro.

can optimize away to avoid bit rot. While at it, replace strcat()

[PULL 8/8] hw/audio/es1370: trace lost interrupts

[marcandre.lureau]

From: Volker Rümelin <vr_qemu@t-online.de>

It turns out that there are drivers which assume that interrupts
can't be lost. E.g. the AROS sb128 driver is such a driver. Add
a lost interrupt tracepoint to debug this kind of issues.
