The bios will now reserve more memory via the E820 functions. Previously we reserved: 0xfffbc000-0xfffbcfff - 4KB - KVM kernel module, EPT identity pages tables 0xfffbd000-0xfffbffff - 12KB - KVM bios, VMC TSS Pages 0xfffc0000-0xffffffff - 256KB - Max KVM bios.bin (usually top 128KB is used) Now we will reserve: 0xfeffc000-0xfeffcfff - 4KB - KVM kernel module, EPT identity pages tables 0xfeffd000-0xfeffffff - 12KB - KVM bios, VMC TSS Pages 0xff000000-0xffffffff - 16MB - Max KVM bios.bin Signed-off-by: Jordan Justen <jordan.l.justen@xxxxxxxxx> --- kvm/bios/rombios.c | 8 ++++---- 1 files changed, 4 insertions(+), 4 deletions(-) diff --git a/kvm/bios/rombios.c b/kvm/bios/rombios.c index 6186199..2d0c153 100644 --- a/kvm/bios/rombios.c +++ b/kvm/bios/rombios.c @@ -4596,14 +4596,14 @@ ASM_END case 5: /* 4 pages before the bios, 3 pages for vmx tss pages, * the other page for EPT real mode pagetable */ - set_e820_range(ES, regs.u.r16.di, 0xfffbc000L, - 0xfffc0000L, 0, 0, 2); + set_e820_range(ES, regs.u.r16.di, 0xfeffc000L, + 0xff000000L, 0, 0, 2); regs.u.r32.ebx = 6; break; case 6: - /* 256KB BIOS area at the end of 4 GB */ + /* 16MB BIOS area at the end of 4 GB */ set_e820_range(ES, regs.u.r16.di, - 0xfffc0000L, 0x00000000L ,0, 0, 2); + 0xff000000L, 0x00000000L ,0, 0, 2); if (extra_highbits_memory_size || extra_lowbits_memory_size) regs.u.r32.ebx = 7; else -- 1.6.0.4 -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
