linux - map specifc virtual address to a specific physical one -

-

To find a way to do this.

Can you tell us kernel version and CPU architecture / type? Generally, if the specific virtual address that you want to map to does not overlap with the kernel virtual address (such as 0xC0000000), and if the physical address that your device does not overlap with the system memory physical address range, then its You can use low-level tasks (if not, you can use mmu to collect language for installation of TLB entries during kernel booting ) The specific virtual a particular address during kernel booting to set the MMU TLB entries to map. I can provide an example based on the 2.6.10 kernel version and the Freescale PowerPC CPU, the Iio_block_mapping function for the object you want.

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge.
