[kvm-unit-tests PATCH 1/2] arm: Change text base address for 32 bit tests when running under kvmtool

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The 32 bit tests do not have relocation support and rely on the build
system to set the text base address to 0x4001_0000, which is the memory
location where the test is placed by qemu. However, kvmtool loads a payload
at a different address, 0x8000_8000, when loading a test with --kernel.
When using --firmware, the default is 0x8000_0000, but that can be changed
with the --firmware-address comand line option.

When 32 bit tests are configured to run under kvmtool, set the text base
address to 0x8000_8000.
