Intel have run out of model space in Family 6 and will start using Family 19 starting with Diamond Rapids. Xen, like Linux, has model checking logic which will malfunction owing to bad assumptions about the family field.
Follow Linux's lead and combine Vendor / Family / Model into a single constant, so it is harder to mismatch family and model checks. https://gitlab.com/xen-project/hardware/xen-staging/-/pipelines/1930124712 Andrew Cooper (3): x86: Rearrange struct cpuinfo_x86 to introduce a vfm field x86/intel-family: Resync with Linux x86/vtd: Switch model check to VFM xen/arch/x86/include/asm/cpufeature.h | 45 ++++++++++-- xen/arch/x86/include/asm/intel-family.h | 96 ++++++++++++++++++++++++- xen/arch/x86/setup.c | 4 +- xen/drivers/passthrough/vtd/quirks.c | 7 +- 4 files changed, 141 insertions(+), 11 deletions(-) -- 2.39.5
