Hi,
a better way to fix the playback glitches is to use a bigger playback
buffer on pulseaudio server side. I suggest you replace your patch with
a patch like this one:

The errors detected in this function necessarily indicate bugs in the rest
of the qemu code, rather than an external or configuration problem.
So, a simple assert() is more appropriate than any more complex error
reporting.

Currently spapr_cpu_init() is hardcoded to handle any errors as fatal.

Here is a draft qemu implementation of my proposed PAPR extension for

The implementation is partially asynchronous, handled in a special thread

This adds a new string to the hypertas property in the device tree,

This is a tentative suggested value, and would need to be standardized by

If doing big-endian linux-user mode, set both the CPSR.E and SCTLR.E0E
bits. This sets big-endian mode for data accesses in AA32 and AA64
resp.

Hi All,
This patch series adds system-mode big-endian support for ARM. It also
implements the setend instruction, and loading of BE binaries even in
LE emulation mode.
Based on Paolo's original work. I have moved all the BE32 related work
to the back of the series. Multiple parties are interested

Implement SCTLR.EE bit which controls data endianess for exceptions
and page table translations. SCTLR.EE is mirrored to the CPSR.E bit

Introduce a disas flag for setting the CPU data endianness. This allows
control of the endianness from the CPU state rather than hard-coding it

Now that CPSR.E is set correctly, prepare for when setend will be able
to change it; bswap data in and out of strex manually by comparing
SCTLR.B, CPSR.E and TARGET_WORDS_BIGENDIAN (we do not have the luxury
of using TCGMemOps).

We'll need the DisasContext in the next patch to retrieve the
desired endianness, so pass it as a whole to gen_aa32_ld*/st*.
Unfortunately we cannot let those functions call get_mem_index,
because of user-mode load/store instructions.

This matches the idiom used by get_user_data_* later in the series,
and will help when bswap_code will be replaced by SCTLR.B.

Support ARM big-endian ELF files in system-mode emulation. When loading
an elf, determine the endianness mode expected by the elf, and set the
relevant CPU state accordingly.
With this, big-endian modes are now fully supported via system-mode LE,
so there is no need to restrict the elf loading to

System emulation only has a little-endian target; BE32 mode
is implemented by adjusting the low bits of the address
for every byte and halfword load and store. 64-bit accesses
flip the low and high words.

There is a CPU data endianness test that is used to drive the
virtio_big_endian test.
Move this up to the header so it can be more generally used for endian
tests. The KVM specific cpu_syncronize_state call is left behind in the
virtio specific function.

Some CPUs are of an opposite data-endianness to other components in the
system. Sometimes elfs have the data sections layed out with this CPU
data-endianess accounting for when loaded via the CPU, byte swaps
(relative to other system components) will occur.
The leading example, is ARM's BE32 mode,
Don't set CPSR.E for BE32 linux-user mode. As linux-user mode models
BE32, using normal BE (and system mode will not), a special case is
needed for user-mode where if sctlr.b is set, the CPU identifies as BE.

bswap_code is a CPU property of sorts ("is the iside endianness the
opposite way round to TARGET_WORDS_BIGENDIAN?") but it is not the
actual CPU state involved here which is SCTLR.B (set for BE32
binaries, clear for BE8).
Replace bswap_code with SCTLR.B, and pass that to arm_
