Subject: [PATCH 36/78] hw/loongarch: virt: pass random seed to fdt
|
|
|
|
If the FDT contains /chosen/rng-seed, then the Linux RNG will use it to
|
|
initialize early. Set this using the usual guest random number
|
|
generation function.
|
|
|
|
This is the same procedure that's done in b91b6b5a2c ("hw/microblaze:
|
|
pass random seed to fdt"), e4b4f0b71c ("hw/riscv: virt: pass random seed
|
|
to fdt"), c6fe3e6b4c ("hw/openrisc: virt: pass random seed to fdt"),
|
|
67f7e426e5 ("hw/i386: pass RNG seed via setup_data entry"), c287941a4d
|
|
("hw/rx: pass random seed to fdt"), 5e19cc68fb ("hw/mips: boston: pass
|
|
random seed to fdt"), 6b23a67916 ("hw/nios2: virt: pass random seed to fdt")
|
|
c4b075318e ("hw/ppc: pass random seed to fdt"), and 5242876f37
|
|
("hw/arm/virt: dt: add rng-seed property").
|
|
|
|
These earlier commits later were amended to rerandomize the RNG seed on
|
|
snapshot load, but the LoongArch code somehow already does that, despite
|
|
not having this patch here, presumably due to some lucky copy and
|
|
pasting.
