eax, ebx, ecx, edx: the values returned by the cpuid instruction for
this function/index combination
+The TSC deadline timer feature (CPUID leaf 1, ecx[24]) is always returned
+as false, since the feature depends on KVM_CREATE_IRQCHIP for local APIC
+support. Instead it is reported via
+
+ ioctl(KVM_CHECK_EXTENSION, KVM_CAP_TSC_DEADLINE_TIMER)
+
+if that returns true and you use KVM_CREATE_IRQCHIP, or if you emulate the
+feature in userspace, then you can enable the feature for KVM_SET_CPUID2.

This directory is _NOT_ for adding arbitrary new firmware images. The
place to add those is the separate linux-firmware repository:
- git://git.kernel.org/pub/scm/linux/kernel/git/dwmw2/linux-firmware.git
+ git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
That repository contains all these firmware images which have been
extracted from older drivers, as well various new firmware images which
To submit firmware to that repository, please send either a git binary
diff or preferably a git pull request to:
David Woodhouse <dwmw2@infradead.org>
+ Ben Hutchings <ben@decadent.org.uk>
Your commit should include an update to the WHENCE file clearly
identifying the licence under which the firmware is available, and
