* [PATCH] libata: move err_mask to ata_queued_cmdAlbert Lee2005-12-06
| | | | | | | | | | | | - remove err_mask from the parameter list of the complete functions - move err_mask to ata_queued_cmd - initialize qc->err_mask when needed - for each function call to ata_qc_complete(), replace the err_mask parameter with qc->err_mask.

* [PATCH] mark several libata datastructures constArjan van de Ven2005-12-01
| | | | | | | | | | | Hi, the patch below marks several libata (and libata-driver) structures const so that they end up in the .rodata segment and don't false-share cachelines with things that get dirtied often.

* [libata ahci] tone down ATAPI errorsJeff Garzik2005-11-16
| | | | | | | | | ATA devices don't generate many errors, so the preferred method is to printk() when they occur. ATAPI devices generate tons of exceptions during the normal course of operation, so this change skips logging the most common class of errors.
* [libata ahci] command completion fixes, improved debug msgsJeff Garzik2005-11-15
| | | | | | | | | - Fix a regression in command completion, which prevented the restart of the DMA engine after the device throws an error. - Pack more hardware info into the port-reset error message. - Promote "welcome to our timeout" message from debug msg to normal printk.
* [libata ahci] error handling fixesJeff Garzik2005-11-14
| | | | | | | | | | Needed to get ATAPI working. - dump hardware error bits, if hardware signals an error - only reset hardware during timeout if a command was active - call ata_qc_complete() with a fine-grained error mask. Needed so that atapi_qc_complete() can distinguish between device errors and other errors.
* [libata ahci] set port ATAPI bit correctlyJeff Garzik2005-11-12
| | | | | | Although according to the documentation this largely only affects desktop LED control, let's make sure we set the ATAPI bit when we have an ATAPI device attached to the port.
* [libata ahci, qstor] fix miscount of scatter/gather entriesJeff Garzik2005-11-12
| | | | | Don't directly reference qc->n_elem, as that might cause an off-by-one error for misaligned (padded) ATAPI transfers.

| | | | | | | Use ata_pad_{alloc,free} in two drivers, to factor out common code. Add ata_pad_{alloc,free} to two other drivers, which needed the padding but had not been updated.

| * [libata] use dev_printk() throughout driversJeff Garzik2005-10-30
| | | | | | | | | | | | A few drivers were not following the standard meme of printing out their driver name and version at module load time; this is fixed as well.

| * [libata] change ata_qc_complete() to take error mask as second argJeff Garzik2005-10-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The second argument to ata_qc_complete() was being used for two purposes: communicate the ATA Status register to the completion function, and indicate an error. On legacy PCI IDE hardware, the latter is often implicit in the former. On more modern hardware, the driver often completely emulated a Status register value, passing ATA_ERR as an indication that something went wrong. Now that previous code changes have eliminated the need to use drv_stat arg to communicate the ATA Status register value, we can convert it to a mask of possible error classes. This will lead to more flexible error handling in the future.

* [PATCH] PCI/libata INTx cleanupBrett M Russ2005-09-08

* [PATCH] libata: fix pio_mask values (take 2)Brett Russ2005-09-07
| | | | | | | | | | | | | | ata_get_mode_mask() uses bits 3 and 4 in the pio_mask to represent PIO modes 3 and 4. The value read from the drive, which reports support for PIO3 and PIO4 in bits 0 and 1, is shifted left by 3 bits and OR'd with 0x7 (which then corresponds to PIO 2-0 in libata). Thus, the drivers below need adjustments to comply with the way pio_mask is used. I changed the masks from the commented values to all support PIO4-0, since the spec mandates that PIO0-2 are supported and there's no reason not to support PIO3 IMO.

| * | [PATCH] Fix HD activity LED with ahciMartin Wilck2005-08-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch: fix wrong HD activity control by ahci driver The ahci driver 1.0 sets the SActive bit on every transaction, causing the LED to light up. The SActive bit is used only for native command queuing (NCQ) which the current driver version doesn't implement. Resetting the SActive bit is the device's responsibility (by sending a "Set Device Bits FIS" to the host adapter) but this is not required in response to non-NCQ commands, and (most) devices don't. Thus the LED stays always on. This patch fixes the LED behavior.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Jens Axboe pointed out that the iounmap() call in libata was occurring too early, and some drivers (ahci, probably others) were using ioremap'd memory after it had been unmapped. The patch should address that problem by way of improving the libata driver API: * move ->host_stop() call after all ->port_stop() calls have occurred. * create default helper function ata_host_stop(), and move iounmap() call there. * add ->host_stop_prewalk() hook, use it in sata_qstor.c (hi Mark). sata_qstor appears to require the host-stop-before-port-stop ordering that existed prior to applying the attached patch.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
