* libata: const-ification bombing runJeff Garzik2005-10-221-1/+1
| | | | | | | Enforce access rules where appropriate. If the compiler is smart enough, this may buy us an optimization or two as a side effect.

* [PATCH] PCI/libata INTx cleanupBrett M Russ2005-09-081-16/+0
| | | | | | | | | Simple cleanup to eliminate X copies of the pci_enable_intx() function in libata. Moved ahci.c's pci_intx() to pci.c and use it throughout libata and msi.c. Signed-off-by: Brett Russ <russb@emc.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* [PATCH] libata: fix pio_mask values (take 2)Brett Russ2005-09-071-1/+1
| | | | | | | | | | | | | | 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.

* [libata ahci] minor remove/unplug path cleanupJeff Garzik2005-08-301-12/+2
| | | | | | | | Don't bother calling a hook, to call our own module, to call a helper than simply calls ionumap(). If you unroll all that convolution, you get a simple kfree()+iounmap() pair of calls.

| * | [PATCH] Fix HD activity LED with ahciMartin Wilck2005-08-231-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | | [libata] license change, other bitsJeff Garzik2005-08-281-16/+24
| |/ |/| | | | | | | | | | | | | | | | | | | - changes license of all code from OSL+GPL to plain ole GPL - except for NVIDIA, who hasn't yet responded about sata_nv - copyright holders were already contacted privately - adds info in each driver about where hardware/protocol docs may be obtained - where I have made major contributions, updated copyright dates
* | libata: release prep (bump versions, etc.)Jeff Garzik2005-08-231-0/+1

| | * libata: Fix use-after-iounmapJeff Garzik2005-05-261-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
| * | [PATCH] drivers/scsi/ahci: add #include req'd for the DMA_{64,32}BIT_MASK ↵domen@coderock.org2005-05-271-0/+1
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | constants The previous patch did not compile cleanly on all architectures so here's a fixed one which #includes <linux/dma-mapping.h>. Use the DMA_{64,32}BIT_MASK constants from dma-mapping.h when calling pci_set_dma_mask() or pci_set_consistent_dma_mask() This patch includes dma-mapping.h explicitly because it caused errors on some architectures otherwise.

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!
