architecture: for now, we do this on the lowest layer only, therefore all requests are handled synchronously (ie. in the scheduler's thread). * Instead of using the block_io module, scsi_disk (and scsi_cd) are now exporting a device on their own, and use an I/O scheduler with an appropriate DMA resource. * There are still lots of TODOs, and it can easily panic - don't update if you intend to demo Haiku. * scsi_periph now only has an io() function that get an io_operation, instead of the previous read/write functions, moved preferred CCB size from those functions into the device registration. * Changed all scsi_periph files to C++. * scsi_cd ported, too, but untested. * Removed block_io from image - it will be removed completely soon. * Temporarily commented an ASSERT() in the ATA bus manager (in case you use it); it's sometimes triggered by the code now, and I haven't yet looked into the issue -- doesn't seem to harm, at least. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26828 a95241bf-73f2-0310-859d-f6bbb57e9c96 |
