Event Timeline
| sys/arm/arm/hypervisor-stub.S | ||
|---|---|---|
| 1 ↗ | (On Diff #26389) | You should add a license. |
| 8 ↗ | (On Diff #26389) | You should add __FBSDID("$FreeBSD$"); here, and wrap the code with #if __ARM_ARCH >= 7 |
| 17–20 ↗ | (On Diff #26389) | Can you add these (and other registers below) to sys/arm/include/sysreg.h then use the macros here. |
| 24 ↗ | (On Diff #26389) | You should add a macro to sys/arm/include/armreg.h for this. |
| sys/arm/arm/locore-v6.S | ||
| 73–75 | I think we should be passing this to initarm via the struct arm_boot_params *. Although I note we are running low on free registers. | |
| sys/conf/files.arm | ||
| 70 | You can make this optional on armv6, we don't need to build it on anything earlier than that. | |

I've applied all the recomandations from Andrew, besides the "struct arm_boot_params *" one.
| sys/arm/arm/hypervisor-stub.S | ||
|---|---|---|
| 48–51 ↗ | (On Diff #26411) | Do we need these comments now? It should be obvious what register each instruction is updating. |
| 55 ↗ | (On Diff #26411) | Can you change this comment to /* ... */ |
| 57 ↗ | (On Diff #26411) | Maybe a comment saying there is an implicit instruction barrier in the eret in the caller. |
| 58 ↗ | (On Diff #26411) | This one can be RET |

Can you check the diff you uploaded didn't replace tabs with spaces. It's not applying to my svn checkout.
