loader: biosdisk interface should be able to cope with 4k sectors Authored by tsoome on Jun 13 2017, 12:24 PM. Tags None Referenced Files
Details The 4kn support in current bios specific biosdisk.c is broken, as the code This work is building the support for custom size sectors, we still do assume For reference, see also: As the GELI is moved above biosdisk "layer", the GELI should just work Need system(s) with 4kn disks - at this time, we only can test data disks because earlier stages only do support 512B sector size too. 512B sector disks are tested.

Event TimelineComment Actions As for the first round I essentially did move the bounce buffer usage from bd_io to strategy; the current geli does assume it is still in bd_io. But I think that is not too hard to work out. The another thing is that for 4kn, we actually do the same LBA/buffer adjustments, so I *think*, it probably is good idea to merge the current geli code in bd_read with the strategy bits, so the LBA/buffer manipulations would get done if it is either 4kn *or* GELI. So we wont duplicate that code. Hm, and I think that should pretty much cover it - of course the geli case would need to use the temporary buffer for decryption - but thats what we use anyhow. Hm, i think that would pretty much cover it. Hm, I wonder if we can make the bd_open() and geli taste a bit more generic too, so we could just use the "normal" strategy for probing...
