* OvmfPkg/ResetVector: Set C-bit when building initial page tableBrijesh Singh2017-07-101-1/+61
| | | | | | | | | | | | | | | | | | | | | SEV guest VMs have the concept of private and shared memory. Private memory is encrypted with the guest-specific key, while shared memory may be encrypted with hypervisor key. Certain types of memory (namely instruction pages and guest page tables) are always treated as private memory by the hardware. The C-bit in PTE indicate whether the page is private or shared. The C-bit position for the PTE can be obtained from CPUID Fn8000_001F[EBX]. When SEV is active, the BIOS is encrypted by the Qemu launch sequence, we must set the C-bit when building the page table.

* OvmfPkg/ResetVector: Depend on PCD values of the page tables.Marvin Häuser2016-11-043-11/+24
| | | | | | | | | | | | | | Currently, the value of the page tables' address is hard-coded in the ResetVector. This patch replaces these values with a PCD dependency. A check for the size has been added to alert the developer to rewrite the ASM according to the new size, if it has been changed.

* OvmfPkg X64 ResetVector: Move page tables from 512KB to 8MBJordan Justen2014-01-212-10/+12
| | | | | | | | | | | | | | | | | | To help consolidate OVMF fixed memory uses, we declare this range in MEMFD and thereby move it to 8MB. We also now declare the table range in the FDF to set PCDs. This allows us to ASSERT that CR3 is set as expected in OVMF SEC. OvmfPkgIa32.fdf and OvmfPkgIa32X64.fdf are updated simply for consistency.

* OvmfPkg: Add platform specific reset vector code for X64Jordan Justen2013-09-246-0/+259
| | | | | | | | | | | | | | | | | | | | | | | KVM has a bug that prevents using page tables in the ROM if the ROM region utilizes the KVM READONLY memory feature. Therefore, we avoid using page tables stored in the ROM. Since OVMF doesn't require memory initialization, we just build page table entries in RAM at 0x80000 very early in the OVMF boot process. This address is just after the 'temp RAM' which is set up by the SEC module. Currently we only set up 4GB of page tables for OVMF's PEI, but DxeIpl will build identity mapped page tables that cover all of the available processor physical address space.
