Cover letter [PATCH 0/3] libata PIO fixes (revised)
Jeff,
The PIO fixes revised according to the previous reviews.
1/3 pio1.diff:
- Modify the "if conditions" in __atapi_pio_bytes() to be more robust.
2/3 pio2.diff:
- Add ATA_FLAG_IO_32BIT to libata.h for hosts with 32-bit data register.
- Modify ata_mmio_data_xfer() and ata_pio_data_xfer() to handle buffer with length not aligned to 32-bit boundary.
3/3 pio3.diff:
- Modify __atapi_pio_bytes() to handle the case when device returns/needs extra data.
(Patch diff'ed against 2.6.13-rc4 tree, 02459eaab98a6a57717bc0cacede148fc76af881)
Tested ok on x86 with Promise PDC20275 and LG DVD-Multi drive.
For your review and advice, thanks.
Albert
