+This directory contains sources for a kvm test suite.
+
+Tests for x86 architecture are run as kernel images for qemu that supports multiboot format.
+Tests uses an infrastructure called from the bios code. The infrastructure initialize the system/cpu's,
+switch to long-mode and calls the 'main' function of the individual test.
+Tests uses a qemu's virtual test device, named testdev, for services like printing, exiting, query memory size etc.
+See file testdev.txt for more details.
+
+To create the tests' images just type 'make' in this directory.
+Tests' images created in ./test/<ARCH>/*.flat
+
+An example of a test invocation:
+qemu-system-x86_64 -device testdev,chardev=testlog -chardev file,id=testlog,path=msr.out -kernel ./test/x86/msr.flat
+This invocation runs the msr test case. The test output is in file msr.out.
+
+
+
+Directory structure:
+.: Makefile and config files for the tests
+./test/lib: general services for the tests
+./test/lib/<ARCH>: architecture dependent services for the tests
+./test/<ARCH>: the sources of the tests and the created objects/images

+Tests in this directory and what they do:
+
+access: lots of page table related access (pte/pde) (read/write)
+apic: enable x2apic, self ipi, ioapic intr, ioapic simultaneous
+emulator: move to/from regs, cmps, push, pop, to/from cr8, smsw and lmsw
+hypercall: intel and amd hypercall insn
+msr: write to msr (only KERNEL_GS_BASE for now)
+port80: lots of out to port 80
+realmode: goes back to realmode, shld, push/pop, mov immediate, cmp immediate, add immediate,
+ io, eflags instructions (clc, cli, etc.), jcc short, jcc near, call, long jmp, xchg
+sieve: heavy memory access with no paging and with paging static and with paging vmalloc'ed
+smptest: run smp_id() on every cpu and compares return value to number
+stringio: outs forward and backward
+tsc: write to tsc(0) and write to tsc(100000000000) and read it back
+vmexit: long loops for each: cpuid, vmcall, mov_from_cr8, mov_to_cr8, inl_pmtimer, ipi, ipi+halt
