| To be done |
| ---------- |
| |
| - See http://scst.sourceforge.net/contributing.html |
| |
| - Add choosing default number of threads for BLOCKIO based on "rotational" |
| sysfs attribute of the device. |
| |
| - Remove cmd->data_len |
| |
| - Reimplement VDISK handler with usage of async. read/write operations |
| (in order to avoid unnecessary context switches) and direct access to |
| the page cache (in order to avoid data copy between it and internal |
| buffers). Requires modifications of the kernel. |
| |
| - Dynamic I/O flow control, when the device queue depth on the target |
| will be dynamically decreased/increased based on how slow/fast the |
| backstorage speed comparing to the target link for current IO |
| pattern. |
| |
| - Fix in-kernel O_DIRECT mode. |
| |
| - Close integration with Linux initiator SCSI mid-level, including |
| queue types (simple, ordered, etc.) and local initiators (sd, st, sg, |
| etc.) support. Requires modifications of the kernel. |
| |
| - Improve task management and Unit Attention conditions handling |
| using ACA in order to make them always reliable. Honoring NACA, QErr, |
| TST, UA_INTLCK_CTRL bits. Requires deep modifications of the kernel. |
| |
| - Better handle of devices DMA restrictions, where needed. |
| |
| - Small ToDo's spread all over the code. |
| |
| - Additional ability for target drivers to ask for command's retry also |
| after xmit_response() and rdy_to_xfer() returned (for example, if a |
| command was successfully sent to the target card, but later it was |
| returned by the card with BUSY completion status). |
| |
| - Advanced SCSI commands support: COPY, EXTENDED COPY, third party |
| RESERVE, etc. |
