Title:
qemu64 CPU model is incorrect
Status in QEMU:
New
Bug description:
At the mom
I finally understand where the problem is.
Qemu's user-mode emulation maps guest threads to native ones by spawning a new
native one
and running a forked copy of the CPUX86State in parallel with the main thread.
This works fine for pretty much every architecture but i386 where the GDT/LDT
comes
Public bug reported:
Given the following C program, qemu-i386 will surely and certainly segfault
when executing it.
The problem is only noticeable if the program is statically linked to musl's
libc and, as written
in the title, it only manifests when targeting i386.
Removing the pthread calls o
The new code in Qemu is correct, the real problem is that the code [1] is
trying to negotiate an invalid working voltage with CMD41.
The SD specification marks the first 15 bits as reserved (except for the 7th,
that's the dual-voltage flag) meaning that compliant cards will timeout as well.
If y
The error message is a rather cryptic "LLVM ERROR: 64-bit code requested on a
subtarget
that doesn't support it!" as it knows Athlon CPUs don't support the AMD64 ISA.
I will relay the tip to the people managing the VMs, I guess this problem went
unnoticed
for so long because there are not many `
Public bug reported:
At the moment the "qemu64" CPU is defined as follows:
```
.vendor = CPUID_VENDOR_AMD,
.family = 6,
.model = 6,
.stepping = 3,
```
According to Wikipedia [1] this means the CPU is defined as part of the
K7 family while the AMD64 ISA was only in
