Good idea.
The ESCC device looks like it's written as a sysbus device. I think the
Ultra 5 has no devices on the root sabre bus. The serial controller is
behind the ebus (essentially isa). I'm guessing I would need to write a
wrapper device around the memory io functions so that it can be used

CET SHSTK/IBT MSRs can be saved/restored with XSAVES/XRSTORS, but
currently the related feature words are not supported, so add the
new entries. XSAVES/RSTORS always use compacted storage format, which
means the supervisor states' offsets are always 0, ignore them while
calculating stardard format
Currently XSAVES dependent features are not supported in CPUID enumeration,
update CPUID(0xD,n>=1) to enable it.
CET XSAVES related enumeration includes:
CPUID(0xD,1):ECX[bit 11]: user mode CET state, controls bit 11 in XSS.
CPUID(0xD,1):ECX[bit 12]: supervisor mode CET state, controls bit 12 in
Control-flow Enforcement Technology (CET) provides protection against
return/jump-oriented programming (ROP/JOP). It includes two
sub-features: Shadow Stack(SHSTK) and Indirect Branch Tracking(IBT).
This patchset is to enable CET related CPUID report, XSAVES/XRSTORS
support and MSR access etc.
CET feature SHSTK and IBT are enumerated via CPUID(EAX=0x7,0):ECX[bit 7]
and EDX[bit 20] respectively. Two CET bits (bit 11 and 12) are defined in
MSR_IA32_XSS to support XSAVES/XRSTORS. CPUID(EAX=0xd, 1):ECX[bit 11] and
ECX[bit 12] correspond to CET states in user and supervisor mode
You can advance 'parts' to track the current path fragment.
The 'index' parameter is unneeded.

Hello, I've been recently working on my own little branch of QEMU

crash in GLXSwapBuffers(); with a SIGILL. I investigated this for about
2 weeks, manually trying to trace the call stack, only to find that

This is not a bug so much as a feature request.
It would be great if there was a pure-software emulation of the x2APIC

Probably not, but there may be a workaround. The closest cpu to Octeon
that is supported in QEMU is "MIPS64R2-generic".
Please try using switch -cpu MIPS64R2-generic in your QEMU command line.
Also, I think you should use qemu-mipsn32 rather than qemu-mips or qemu-
mips64.

I am sorry I haven't dealt with this bug for quite a while. KDE 5 is not
properly working on my distro, and I wanted to test it when it
stabilises.
If qemu dislikes long-standing bugs, this bug can be closed, and I'll
open a new one when I have time to test it on the new KDE.
