| * | [efi] Centralise definition of efi_cpu_nap() | Michael Brown | 2024-09-13 | 1 | -57/+0 |
| | | | | | | | | | | Define a cpu_halt() function which is architecture-specific but platform-independent, and merge the multiple architecture-specific implementations of the EFI cpu_nap() function into a single central efi_cpu_nap() that uses cpu_halt() if applicable.

| * | [efi] Fix hang during ExitBootServices() | Ross Lagerwall | 2024-01-31 | 1 | -1/+5 |
| | | | | | | | | | | | | | | | | When ExitBootServices() invokes efi_shutdown_hook(), there may be nothing to generate an interrupt since the timer is disabled in the first step of ExitBootServices(). Additionally, for VMs OVMF masks everything from the PIC (except the timer) by default. This means that calling cpu_nap() may hang indefinitely. This was seen in practice in netfront_reset() when running in a VM on XenServer. Fix this by skipping the halt if an EFI shutdown is in progress.
