Since a4c2735f35 (cpu: move Qemu[Thread|Cond] setup into common code,
2024-05-30) these fields are now allocated at cpu_common_initfn(). So
let's make sure we also free them at cpu_common_finalize().
Furthermore, the code also frees these on round robin, but we

The musb_reset function was causing a memory leak by not properly freeing
the memory associated with USBPacket instances before reinitializing them.
This commit addresses the memory leak by adding calls to usb_packet_cleanup
for each USBPacket instance before reinitializing them with
This commit handles invalid address accesses gracefully in both read and write
functions. Instead of asserting and aborting, it logs an error message and
returns
a neutral value for read operations and does nothing for write operations.

This patch addresses a potential out-of-bounds memory access issue in the
tcx_blit_writel function. It adds bounds checking to ensure that memory
accesses do not exceed the allocated VRAM size. If an out-of-bounds access
is detected, an error is logged using qemu_log_mask.

Hi All,
I am trying to enable vhost user input with xen hypervisor on i.MX95, using qemu
vhost-user-input. But meet " Invalid vring_addr message ". My xen domu cfg:
'-chardev', 'socket,path=/tmp/input.sock,id=mouse0',
'-device', 'vhost-user-input-pci,chardev=mouse0',
Anyone knows what missing?
Updated many VSX instructions to use tcg_gen_qemu_ld/st_i128, instead of using
tcg_gen_qemu_ld/st_i64 consecutively.
Introduced functions {get,set}_vsr_full to facilitate the above & for future
use.

Updated instructions {l, st}vx to use tcg_gen_qemu_ld/st_i128,
instead of using 64 bits loads/stores in succession.
Introduced functions {get, set}_avr_full in vmx-impl.c.inc to
facilitate the above, and potential future usage.

Updating a bunch of VMX and VSX storage access instructions to use
tcg_gen_qemu_ld/st_i128 instead of using tcg_gen_qemu_ld/st_i64 in
succession; as suggested by Richard, in my decodetree patches.
Plus some minor clean-ups to facilitate the above in case of VMX insns.
Change log:
v2 : Applied
Those functions are used to ld/st data to and from Altivec registers,
in 64 bits chunks, and are only used in vmx-impl.c.inc file,
hence the clean-up movement.
