The MSA 12 facility depends on MSA 6 for which only its

Add RDT code to Associate CLOSID with RMID / set RMID for monitoring,
write COS, and read monitoring data. This patch does not add code for
the guest to interact through these things with MSRs, only the actual
ability for the RDT device to do them.

Adjust minimum CPUID level if RDT monitoring or allocation features are
enabled to ensure that CPUID will return them.

The aim of this patch series is to emulate Intel RDT features in order
to make testing of the linux Resctrl subsystem possible with Qemu.

The changes made
From: Hendrik Wüthrich
Change config to show RDT, add minimal code to the rdt.c module to make
sure things still compile.

Implement rdmsr and wrmsr for the following MSRs:
* MSR_IA32_PQR_ASSOC
* MSR_IA32_QM_EVTSEL
* MSR_IA32_QM_CTR
* IA32_L3_QOS_Mask_n
* IA32_L2_QOS_Mask_n
* IA32_L2_QoS_Ext_BW_Thrtl_n
This allows for the guest to call RDT-internal functions to
associate an RMID with a

Just what *is* qemu's raw disk image file format?
Is it just a byte-by-byte, block-by-block copy of the hard drive, such as
can be produced by executing
cp /dev/hda imagefile
? Or does it have more structure or headers or such?
