This is a fix just due to being too much of a type-A person. I noticed the issue while reading over the function, and decided to fix it, even though it's unlikely to be a problem ever because top is read-mostly (like written once, then only read, type of mostly). Signed-off-by:

It's pretty safe to not even bother checking for NULL when using malloc and friends, but if we do check, then fail hard. Signed-off-by:

We recently modified how mmu_enabled works in order to speed spinlocks up (see c33efcf3 and b141dbac). Unfortunately c33efcf3 was a bit hasty in removing mmu_set_enabled. I had forgotten one of the reasons I introduced it was because secondaries don't go through mmu_enable(), they go straight to asm_mmu_enable from secondary_entry. This patch brings it back, albeit renamed to mmu_mark_enabled to match mmu_mark_disabled. The patch also moves mmu_mark_disabled from psci code to smp code, as psci code shouldn't need to care about mmu stuff, and because we now have a nice balance in the smp code - we mark the mmu disabled for the secondary before we kick it, and then mark it enabled on the init. Finally, a bit unrelated, I've added a lengthy comment to __mmu_enabled in order to warn about what can't be called from there. We need to be cautious there because mmu_enabled() gets scattered around easily, being in basic functions, and thus there's risk of recursion. Signed-off-by:

make install wasn't very useful without also installing scripts for the qemu command lines. I suspect 'make install' was never used. Installing standalone tests could be useful though, so let's do that instead. Signed-off-by:

This is a pretty ugly bash script, wrapped around a couple ugly bash scripts, and it generates an ugly sh script. But, it gets the job done. What's the job? Take a unit test and generate a standalone script that can be run on any appropriate system with an appropriate qemu. This makes distributing single, pre-compiled, unit tests easy, even through email, which can be useful for getting test results from a variety of users, or even for deploying the unit test as utility (if it works that way) in a distribution. "Packaging" works like shar, but doesn't use shar, as it's better to avoid the dependency. Can be used to create just one unit test, or all of them ('make standalone'). The standalone test(s) are placed in ./tests. Signed-off-by: -

Test resampling of level interrupts after EOI, by leaving the IRQ line set in the ISR. One tests does reset the IRQ line after a while, the other uses masking instead in the ISR. Signed-off-by: -

Keeping the selector that was loaded from the 32-bit GDT is okay, because only code segment descriptors differ between 32- and 64-bit mode. In fact the same is true for %ss as well, so let's just remove the whole segment loading from load_tss. Thanks to Bandan Das for debugging. Reported-by:

kvm-unit-tests was keeping DS/ES/FS/GS loaded with the segment descriptors provided by the multiboot boot loader (which are 32-bit), and instead loading SS with 0. The vmx.flat test failed because KVM did not like doing writes into such an SS. Load again the segment registers after entering 64-bit mode, for both the BSP and the APs. Signed-off-by:

spinlock torture tests made it clear that checking mmu_enabled() every time we call spin_lock is a bad idea. As most tests will want the MMU enabled the entire time, then we can inline a light weight "nobody disabled the mmu" check, and bail out early. Adding a light weight inlined check vs. a compile-time flag suggested by Paolo. Signed-off-by:

The mmu is enabled automatically for all cpus, they must disable it themselves if they don't want it on. Switch from managing a cpumask of enabled cpus to one of disabled cpus. This allows us to remove the mmu_set_enabled call from secondary_cinit, and the function all together. Signed-off-by:

Allow unit test cpus to disable the MMU. Why not? We want the test framework to be as flexible as possible. Callers will have to deal with the cache coherency fallout... Cache flush support is still forthcoming to the framework though. Signed-off-by:

It shouldn't be necessary to use a barrier on the way into spin_lock. We'll be focused on a single address until we get it (exclusively) set, and then we'll do a barrier on the way out. Also, it does make sense to do a barrier on the way in to spin_unlock, i.e. ensure what we did in the critical section is ordered wrt to what we do outside it, before we announce that we're outside.

GCC 5.0.0 enables raw strings by default and they have higher priority than macros, thus R"[...]" is interpreted incorrectly: lib/x86/isr.c:112:30: error: invalid character ')' in raw string delimiter lib/x86/isr.c:112:8: error: stray ‘R’ in program lib/x86/isr.c:112:26: error: expected ‘:’ or ‘)’ before string constant "orl $0x200, (%%"R"sp)\n\t" Fix it by putting a space between macro R and a string literal.
