Hi, I am trying to take these patches, in the hope that they help with some of the test issues I am having with the kvm-only build, but they fail with: target/arm/Kconfig: does not exist in index so I guess I need the "target/arm/Kconfig" series right, how can I find that one?

KVM requires the target cpu to be at least ARMv8 architecture (support on ARMv7 has been dropped in commit 82bf7ae84ce: "target/arm: Remove KVM support for 32-bit Arm hosts"). Only enable the following ARMv4 CPUs when TCG is available: - StrongARM (SA1100/1110) - OMAP1510 (TI925T) The following machines are no more built when TCG is disabled: - cheetah Palm Tungsten|E aka. Cheetah PDA (OMAP310) - sx1 Siemens SX1 (OMAP310) V2 - sx1-v1 Siemens SX1 (OMAP310) V1 Signed-off-by: Philippe Mathieu-Daudé <f4bug@amsat.org> --- default-configs/devices/arm-softmmu.mak | 2 -- hw/arm/Kconfig | 4 ++++ target/arm/Kconfig | 4 ++++ 3 files changed, 8 insertions(+), 2 deletions(-)
