When disabling MSI/MSIX via "ibm,change-msi" RTAS call, no check was made
if MSI or MSIX is actually supported and the MSI message was reset
unconditionally. If this happened on a device which does not support MSI
(but does support MSIX, otherwise "ibm,change-msi" would not be called),
this device
Commit 58ac321135a introduced a check to ide dma processing which
constrains all requests to drive size. However, apparently, some
valid requests (like TRIM) does not fit in this constraint, and
fails in 2.1. So check the range only for reads and writes.

This test runs dummy function with coroutine by using
two enter and one yield since which is a common usage.
So we can see the cost introduced by corouting for running
one function, for example:
Run operation 2000 iterations 4.841071 s, 4131K operations/s
242ns per coroutine

Hi,
QMP command 'query-memory-devices' returns DIMM slots IDs as integers,
while 'query-acpi-ospm-status' returns them as strings. Why is this the
case? Aren't slot IDs numeric anyway?
I've looked up the ACPI specs but I can't find any specific mention of how
DIMM IDs should be represented, so wh

my aim is to add Infineon's TriCore architecture to QEMU. This series of
patches adds the target stubs, a basic testboard and a softmmu for system mode
emulation. Furthermore it adds all the 16 bit long instructions of the
architecture grouped by opcode format.

Yes...
Time is a problem, and it‘s currently running out... ;-)
I think the first step is to reason about possible approaches and how
they can be implemented in QEMU. The implementation can follow later :-)
Thank you for the hint with the drive-mirror feature.

Hi Edgar,
I was just writing a test to verify the correct behavior of the SCR AW/FW
bits and I think there is an issue.
During an SCR write an initial valid mask is set from SCR_MASK which is
defined to not include these bits. Then these bits are hard-coded into the
write value using RES1. Last

This series of patches is the result of executing the Linux Test Program

Some of the changes are not technically unique to Power, but are effectively
so. For

When the ipc system call is used to wrap a semctl system call,
the ptr argument to ipc needs to be dereferenced prior to passing
it to the semctl handler. This is because the fourth argument to
semctl is a union and not a pointer to a union.

The argument to the mlockall system call is not necessarily the same on

The semun union used in the semctl system call contains both an int (val) and
pointers. In cross-endian situations on 64 bit targets, the value passed to

field in the correct location. In order to rectify this, the other h
For those target ABIs that use the ipc system call (e.g. POWER),

to do_ipc should be declared as abit_lo
The msgsnd system call takes an argument that describes the message

The clock_nanosleep syscall is unusual in that it returns positive
numbers in error handling situations, versus returning -1 and setting
errno, or returning a negative errno value. On POWER, the kernel will
set the SO bit of CR0 to indicate failure in a syscall. QEMU has
generic handling to do th
The get_ppc64_abi is used to determine the ELF ABI (i.e. V1 or V2). This
routine is currently implemented in the linux-user/elfload.c file but
is useful in other scenarios. Move the routine to a more generally

Although not technically not required by POSIX, the writev system call will
typically write out its buffers individually. That is, if the first buffer
is written successfully, but the second buffer pointer is invalid, then
the first chuck will be written and its size is returned.
