* ide: prefix messages from IDE PCI host drivers by driver nameBartlomiej Zolnierkiewicz2008-07-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Prefix messages from IDE PCI host drivers by driver name instead of marketed chipset name (it is still possible to exactly identify the particular chipset basing on driver messages). As a bonus this provides nice code savings for some drivers: text data bss dec hex filename 3826 112 8 3946 f6a drivers/ide/pci/amd74xx.o.before 2786 112 8 2906 b5a drivers/ide/pci/amd74xx.o.after 764 108 0 872 368 drivers/ide/pci/cs5520.o.before 680 108 0 788 314 drivers/ide/pci/cs5520.o.after 1680 112 4 1796 704 drivers/ide/pci/generic.o.before 1155 112 4 1271 4f7 drivers/ide/pci/generic.o.after 7128 792 0 7920 1ef0 drivers/ide/pci/hpt366.o.before 6984 792 0 7776 1e60 drivers/ide/pci/hpt366.o.after 2800 148 0 2948 b84 drivers/ide/pci/pdc202xx_new.o.before 2523 148 0 2671 a6f drivers/ide/pci/pdc202xx_new.o.after 2831 148 0 2979 ba3 drivers/ide/pci/pdc202xx_old.o.before 2683 148 0 2831 b0f drivers/ide/pci/pdc202xx_old.o.after 3776 112 4 3892 f34 drivers/ide/pci/piix.o.before 2804 112 4 2920 b68 drivers/ide/pci/piix.o.after 4693 116 0 4809 12c9 drivers/ide/pci/siimage.o.before 4600 116 0 4716 126c drivers/ide/pci/siimage.o.after Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

* ide: filter out "default" transfer mode values in set_xfer_rate()Bartlomiej Zolnierkiewicz2008-07-23
| | | | | | | | | | | | | | | | | | | | | | | | | | * Filter out "default" transfer mode values (0x00 - default PIO mode, 0x01 - default PIO mode w/ IORDY disabled) in write handler for obsoleted /proc/ide/hd?/settings:current_speed setting. Allowing "default" transfer mode values is a dangerous thing to do as we don't support programming controller to the "default" transfer mode and devices often use different values for the default and maximum PIO mode (i.e. PIO2 default and PIO4 maximum) so the controller will stay programmed for higher PIO mode while device will use the lower PIO mode. There is no functionality loss as by using special IOCTLs device can still be programmed to "default" transfer modes (it is only useful for debugging/testing purposes anyway). * Remove no longer needed IDE_HFLAG_ABUSE_SET_DMA_MODE host flag, it was previously used by few host drivers to program the controller to PIO0 timings for "default" transfer mode == 0x01 (although some host drivers would program invalid PIO timings instead). * Cleanup ide_set_xfer_rate() and add BUG_ON().

* ide: add ide_use_fast_pio() helper (v3)Bartlomiej Zolnierkiewicz2007-02-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * add ide_use_fast_pio() helper for use by host drivers * add DMA capability and hwif->autodma checks to ide_use_dma() - au1xxx-ide/it8213/it821x drivers didn't check for (id->capability & 1) [ for the IT8211/2 in SMART mode this check shouldn't be made but since in it821x_fixups() we set DMA bit explicitly: if(strstr(id->model, "Integrated Technology Express")) { /* In raid mode the ident block is slightly buggy We need to set the bits so that the IDE layer knows LBA28. LBA48 and DMA ar valid */ id->capability |= 3; /* LBA28, DMA */ we are better off using generic helper if we can ] - ide-cris driver didn't set ->autodma [ before the patch hwif->autodma was only checked in the chipset specific hwif->ide_dma_check implementations, for ide-cris it is cris_dma_check() function so there no behavior change here ] v2: * updated patch description (thanks to Alan Cox for the feedback) v3: * updated for scc_pata driver Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

* [PATCH] 64bit resource: fix up printks for resources in ide driversGreg Kroah-Hartman2006-06-27

* Fix up more strange byte writes to the PCI_ROM_ADDRESS config wordLinus Torvalds2005-09-13
| | | | | | | | | | | It's a dword thing, and the value we write is a dword. Doing a byte write to it is nonsensical, and writes only the low byte, which only contains the enable bit. So we enable a nonsensical address (usually zero), which causes the controller no end of problems. Trivial fix, but nasty to find. Signed-off-by: Linus Torvalds <torvalds@osdl.org>

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!
