From fc57d6c4c2848726be1361f6dee3c33e7551b857 Mon Sep 17 00:00:00 2001 From: Patrick Rudolph Date: Tue, 12 Nov 2019 16:30:14 +0100 Subject: cpu/x86/lapic: Support x86_64 and clean up code Most LAPIC registers are 32bit, and thus the use of long is valid on x86_32, however it doesn't work on x86_64. * Don't use long as it is 64bit on x86_64, which breaks interrupts in QEMU and thus SeaBIOS wouldn't time out the boot menu * Get rid of unused defines * Get rid of unused atomic xchg code Tested on QEMU Q35 with x86_64 enabled: Interrupts work again. Tested on QEMU Q35 with x86_32 enabled: Interrupts are still working. Tested on Lenovo T410 with x86_64 enabled.
