Subject: [PATCH 50/78] target/loongarch: Add compatible support about VM
|
|
reboot
|
|
|
|
With edk2-stable202408 LoongArch UEFI bios, CSR PGD register is set only
|
|
if its value is equal to zero for boot cpu, it causes reboot issue. Since
|
|
CSR PGD register is changed with linux kernel, UEFI BIOS cannot use it.
|
|
|
|
Add workaround to clear CSR registers relative with TLB in function
|
|
loongarch_cpu_reset_hold(), so that VM can reboot with edk2-stable202408
|
|
UEFI bios.
