openslx-ng/ipxe.git/src/drivers/ata, branch master Fork of ipxe; additional commands and features https://git.openslx.org/openslx-ng/ipxe.git/atom/src/drivers/ata?h=master 2007-07-29T01:31:14+00:00 Quick hack to get AoE back in to the tree, on a par with the current 2007-07-29T01:31:14+00:00 Michael Brown 2007-07-29T01:31:14+00:00 urn:sha1:43013da9bf02439b4726d8afef15f7ce97d1c469 iSCSI hack. Create and use async_block() macro; it cuts down on the visual overhead 2007-01-16T08:10:54+00:00 Michael Brown 2007-01-16T08:10:54+00:00 urn:sha1:ff8528ea9a69ca2ef6cfbed0b7a1283e165aabe6 of blocking on asynchronous operations, when that isn't an important aspect of the code. Gave asynchronous operations approximate POSIX signal semantics. This 2007-01-15T08:49:10+00:00 Michael Brown 2007-01-15T08:49:10+00:00 urn:sha1:4e20d73bb52326261f8cf49c20d6de2edea309ee will enable us to cascade async operations, which is necessary in order to properly support DNS. (For example, an HTTP request may have to redirect to a new location and will have to perform a new DNS lookup, so we can't just rely on doing the name lookup at the time of parsing the initial URL). Anything other than HTTP is probably broken right now; I'll fix the others up asap. Backing out last change; no immediate plans to make the whole block-device 2006-06-01T11:14:59+00:00 Michael Brown 2006-06-01T11:14:59+00:00 urn:sha1:1f394c2f7c81df27b39c3f76715427398625b048 layer asynchronous, so keeping the sync/async boundary within aoedev.c seems cleanest for now. ATA devices are now asynchronous. The ATA layer itself now performs the 2006-05-31T18:57:11+00:00 Michael Brown 2006-05-31T18:57:11+00:00 urn:sha1:99ef98d0bffdb9b8c67ad3892d533d33221529f0 async_wait(), though we may wish to move this higher up the stack, and consider making the block device model asynchronous. (There is only a marginal cost for synchronous devices, since they can simply call async_done() before returning; async_wait() will work seamlessly in this situation). Added generic asynchronous operations code. 2006-05-31T14:34:17+00:00 Michael Brown 2006-05-31T14:34:17+00:00 urn:sha1:68125bc44173893fb3af08085b0b6b823b60d030 Removed data_in_len and data_out_len from ata_command structure; the lengths are implied by the sector count and the presence of the data_in or data_out pointers. Changed AoE code to use subcommands by default, and made aoe_issue() nonblocking (with completion via async_wait()). Handle multi-sector reads by splitting them into subcommands. 2006-05-29T08:25:31+00:00 Michael Brown 2006-05-29T08:25:31+00:00 urn:sha1:654133889709631cb7aa9390134cada1b7067c86 Initial AoE implementation.
