14 hourskern/amd64: Do low-level processor configurationIan Moffett
This commit seperates low-level processor configuration into the cpu_loinit() function. This is to be called for the BSP and per AP. Signed-off-by: Ian Moffett <ian@osmora.org>
15 hourskern/amd64: mmu: Add mu_pmap_forkvas() helperIan Moffett
The mu_pmap_forkvas() function copies the current virtual address with the user porition zeroed. Signed-off-by: Ian Moffett <ian@osmora.org>
17 hourskern/amd64: mp: Sync MTRRs between APs and BSPIan Moffett
Section 11.11.8 of the Intel SDM states that all MTRRs in a multiprocessing system must be synced to prevent undefined behavior. Signed-off-by: Ian Moffett <ian@osmora.org>
