Temkin <temkink@xxxxxxxxxxxx> Date: Thu Apr 28 13:14:07 2016 -0400 xen/arm64: ensure that the correct SP is used for exceptions The ARMv8 architecture has a SPSel ("stack pointer selection") machine register that allows us to determine which exception level's stack pointer is loaded when an exception occurs. As we don't want to use the non-privileged SP_EL0 stack pointer -- or even assume that SP_EL0 points to a valid address in the hypervisor context-- we'll need to ensure that our EL2 code sets the SPSel to SP_ELn mode, so exceptions that trap to EL2 use the EL2 stack pointer. This corrects an issue that can manifest as a hang-on-IRQ on some arm64 cores if the firmware/bootloader has previously initialized SPSel to 0; in which case Xen's exceptions will incorrectly use an invalid SP_EL0, and will endlessly spin on the synchronous abort handler.

Prefetch does not mean that the data/instruction has to be used/executed in code flow. All PTEs that appear to be valid to MMU must contain valid physical address with proper attributes otherwise MMU table walk might cause imprecise asynchronous aborts. The way current XEN code is preparing page tables for frametable and xenheap memory can create bogus PTEs. This patch fixes the issue by clearing page table memory before populating EL2 L0/L1 PTEs. Without this patch XEN crashes on Qualcomm Technologies server chips due to asynchronous aborts. The speculative/prefetch feature explanation is scattered everywhere in ARM specification but below two sections have useful information. E2.8 Memory types and attributes (ver DDI0487A_h) G4.12.6 External abort on a translation table walk (ver DDI0487A_h) Signed-off-by: Vikram Sethi <vikrams@xxxxxxxxxxxxxx> Signed-off-by: Shanker Donthineni <shankerd@xxxxxxxxxxxxxx> Acked-by: Julien Grall <julien.grall@xxxxxxx> commit c0bb033951c7595a020025e2e765e0e5b4aa1312 Author: Julien Grall <julien.grall@xxxxxxx> Date: Wed Apr 27 12:22:53 2016 +0100 xen/arm: Force broadcast of TLB and instruction cache maintenance instructions UP guest may use TLB instructions to flush only on the local CPU. Therefore, TLB flush will not be broadcasted across all the CPUs within the same innershareable domain. When the vCPU is migrated between different CPUs, it may be rescheduled to a previous CPU where the TLB has not been flushed. The TLB may contain stale entries which will result to translate incorrectly a VA to IPA or even cause TLB conflicts. To avoid a such situation, it is possible to set HCR_EL2.FB, which will force the broadcast of TLB and instruction cache maintenance instructions. The performance impact of setting HCR_EL2.FB will depend on how often a guest makes use of local flush instructions. ARM64 Linux kernel is SMP-aware (no possibility to build only for UP). Most of the flush instructions are innershareable. The local flushes are limited to the boot (1 per CPU) and when a task is getting a new ASIC. Therefore the impact of setting HCR.FB for those guests is very limited. ARM32 Linux kernel offers the possibility to be built either for SMP or UP. The number of local flush is very limited in the former kernel whilst the latter will only issue local flushes. Therefore there will be an impact to set HCR.FB for guest kernel only built for UP. Note that the SMP kernel can run in a domain using 1 vCPU and it will still make use of innershareable flush instruction. Looking at other OSes, such as FreeBSD, they are very similar to ARM32 Linux kernel (i.e offering two configuration: SMP and UP). However, nothing prevents an SMP-aware kernel to make more often use of local flush instrutions. In the case that HCR_EL2.FB is not set, Xen would need to: * Flush all the TLBs for the VMID associated to this domain * Invalidate all the entries from the branch predictor * Invalidate all the entries from the instruction cache Those actions would only be needed when the vCPU is migrating between 2 physical CPUs. Whilst this solution would have a negative performance impact on kernels which do not heavily use local flush instructions, this may improve performance for kernels only built for UP system. For now implement the easiest solution (i.e setting HCR_EL2.FB). We can revisit it if the performance impact is too high for UP kernel.
