Sprinkle in some more isbs after context-changing operations, as the ARM ARM states we should. I haven't seen any problems without them, but we should do it right. Also, *actually* set the MAIR in asm_mmu_enable. We were reading, not writing... Luckily this was just spotted while adding the isbs, rather than leading to a nightmare debug session some day...

Move the spin_lock/unlock declarations to lib/x86/asm/spinlock.h, allowing lib code, e.g. lib/report.c, to use spinlocks. Signed-off-by:

This is similar to emulator.c, that does not run on 32-bit systems. This bug happens (due to kvm_mmu_page_fault's call to the emulator) during Windows 7 boot. Reported-by:

Paolo Bonzini <pbonzini@redhat.com> --- v1->v2: go through kvm_mmu_page_fault like Windows 7 does. Emulation of locked operations on MMIO does not go through the cmpxchg path, gva_to_gpa fails.

There is a failure to build on 32-bit hosts: x86/hypercall.c: In function ‘test_edge’: x86/hypercall.c:42:2: error: ‘test_rip’ undeclared (first use in this function) test_rip = 0; ^ This patch fixes this issue. Signed-off-by:

We used MMIO (xAPIC) for x2APIC. This is the same as using xAPIC in globally disabled mode, and APICv enforces this by returning 0 on APIC MMIO reads under x2APIC. Signed-off-by:

x86/unittests.cfg uses the variant with underscore. Rename tscdeadline-latency.c instead of fixing x86/unittests.cfg because we use only underscores elsewhere. Signed-off-by:

Implement asm_mmu_enable and flush_tlb_all, and then make a final change to mmu.c in order to link it into arm64. The final change is to map the code read-only. This is necessary because armv8 forces all writable code shared between EL1 and EL0 to be PXN. Signed-off-by:

This changes the layout for arm too, but that's fine. The only thing to keep in mind is that while arm64 will have a single 64k page for its stack, arm will have 16 4k pages. If the number of stack pages matters, then unit tests that want to work for both arm and arm64, may need to avoid using more than one page, even though the memory is there. Signed-off-by:

* don't assume 1G PGDIR_SIZE or L1_CACHE_BYTES pgd alignment * use page level descriptors for non-I/O memory * apply new pgd/pud/pmd/pte methods * split mmu.h to share function declarations * use more generic flag names in mmu.c Signed-off-by:

To use page level descriptors we need some pgd/pud/pmd/pte methods, and a few more flags defined. Signed-off-by:

This is the initial drop of the arm64 test framework and a first test that just checks that setup completed (a selftest). kvm isn't needed to run this test unless testing with smp > 1. Try it out with yum install gcc-aarch64-linux-gnu ./configure --cross-prefix=aarch64-linux-gnu- --arch=arm64 make QEMU=[qemu with aarch64, mach-virt, and chr-testdev] ./run_tests.sh Signed-off-by:

Files in lib/arm including "asm/someheader.h" will get lib/arm/asm/someheader.h, not lib/asm/someheader.h. So we need to use <> instead of "" in order to prepare for headers of the same name, but for a different arch. We change all '#include's of all arm files, as consistency looks better. Signed-off-by:

Separate the concepts of an 'svc', the syscall instruction present on both arm and arm64, and 'svc mode', which is arm's kernel mode, and doesn't exist on arm64. kernel mode on arm64 is modeled with exception level 1 (el1). Signed-off-by:

When $ARCH != $TEST_DIR we should look there too. This patch cheats though and makes cscope always look there, but then gets rid of the duplicates generated when $ARCH == $TEST_DIR. Signed-off-by:

So far only applied in a couple obvious places, where temporary prefixes were already used. Signed-off-by:
-
Andrew Jones authored
Add some methods to report in order to manage output prefixes. Also add strstr to string, as it was useful for implementing report_prefix_pop. Prefixes can be useful, as test code frequently has the following pattern main() { foreach(subtest) run(subtest) } But, if we want output lines to include 'subtest: ', then we need report("%s: ...", cond, subtest, ...) for each report line. With push/pop we can now just do subtest() { report_prefix_push(subtest); report(...); ... report(...); report_prefix_pop(); } Signed-off-by: -

Previously KVM ignored the mod field of MOVBE instruction, so MOVBE from register to register succeeds, although it should fail (cause a #UD exception). This test check that a #UD is indeed delivered upon such MOVBE. The test would not work if MOVBE is unsupported. Signed-off-by:Nadav Amit <namit@cs.technion.ac.il>
