When compiled with clang, the following statement gets converted into a movaps instructions. mem->u[0] = 5; mem->u[1] = 6; mem->u[2] = 7; mem->u[3] = 8; Since mem is an unaligned pointer to sse_union, we get a GP when running. Let's avoid using a pointer to sse_union at all, since doing so implies that the pointer is aligned to 128 bits.

Old Intel CPUs, which do not support control protection exception, do not expect an error code for #CP, while new ones expect an error-code. Intel SDM does not say that the delivery of an error-code for #CP is conditional on anything, not even CPU support of CET. So it appears that the correct testing is just to skip the error-code delivery test for the #CP exception.

KVM knows to emulate both vmcall and vmmcall regardless of the actual architecture. Native hardware does not behave this way. Based on the availability of test-device, figure out that the test is run on non-KVM environment, and if so, run vmcall/vmmcall based on the actual architecture. Signed-off-by: -

If there are no test devices, we might be running on bare-metal or other environment, in which port 0xF4, which reports the test result, is not monitored. In such environments, print also the result of the test to the serial console. For realmode: just give a simple indication whether the test passed or failed in a similar fashion. This can allow automation tools to figure out the test is done and its result. Signed-off-by: -

Add a test to verify that KVM correctly handles the case where two or more non-leaf page table entries point at the same table gfn, but with different parent access permissions. For example, here is a shared pagetable: pgd[] pud[] pmd[] virtual address pointers /->pmd1(u--)->pte1(uw-)->page1 <- ptr1 (u--) /->pud1(uw-)--->pmd2(uw-)->pte2(uw-)->page2 <- ptr2 (uw-) pgd-| (shared pmd[] as above) \->pud2(u--)--->pmd1(u--)->pte1(uw-)->page1 <- ptr3 (u--) \->pmd2(uw-)->pte2(uw-)->page2 <- ptr4 (u--) pud1 and pud2 point to the same pmd table The test is useful when TDP is not enabled.

arm/arm64: target-efi prep This series mostly prepares kvm-unit-tests/arm for targeting EFI platforms. The actually EFI support will come in another series, but these patches are good for removing assumptions from our memory maps and about our PSCI conduit, even if we never merge EFI support.

The method can be smc in addition to hvc, and it will be when running on bare metal. Additionally, we move the invocations to assembly so we don't have to rely on compiler assumptions. We also fix the prototype of psci_invoke. function_id should be an unsigned int, not an unsigned long. Reviewed-by:

Keep as much memory layout assumptions as possible in init::start and a single setup function. This prepares us for calling setup() from different start functions which have been linked with different linker scripts. To do this, stacktop is only referenced from init::start, making freemem_start a parameter to setup(). We also split mem_init() into three parts, one that populates the mem regions per the DT, one that populates the mem regions per assumptions, and one that does the mem init. The concept of a primary region is dropped, but we add a sanity check for the absence of memory holes, because we don't know how to deal with them yet. Reviewed-by:

Rather than making too many assumptions about the memory layout in mmu code, just set up the page tables per the memory regions (which means putting all the memory layout assumptions in setup). To ensure we get the right default flags set we need to split the primary region into two regions for code and data. We still only expect the primary regions to be present, but the next patch will remove that assumption too. (Unfortunately we still have an assumption in setup_mmu. We assume the range 3G-4G is available for the virtual memory allocator. We'll need to remove that assumption as well with another patch in order to support arbitrary memory maps.) Reviewed-by:

By providing a proper ioremap function, we can just rely on devices calling it for each region they need (as they already do) instead of mapping a big assumed I/O range. We don't require the MMU to be enabled at the time of the ioremap. In that case, we add the mapping to the identity map anyway. This allows us to call setup_vm after io_init. Why don't we just call setup_vm before io_init, I hear you ask? Well, that's because tests like sieve want to start with the MMU off, later call setup_vm, and all the while have working I/O. Some unit tests are just really demanding... While at it, ensure we map the I/O regions with XN (execute never), as suggested by Alexandru Elisei. Reviewed-by:
