If ->dma_base is not set (== PCI BAR4 cannot be reserved) then DMA hooks shouldn't be initialized or bad things will happen. Acked-by: NSergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: NBartlomiej Zolnierkiewicz <bzolnier@gmail.com>

* Rename ide_pci_device_t.flags to ide_pci_device_t.host_flags and IDEPCI_FLAG_ISA_PORTS flag to IDE_HFLAG_ISA_PORTS. * Add IDE_HFLAG_SINGLE flag for single channel devices. * Convert core code and all IDE PCI drivers to use IDE_HFLAG_SINGLE and remove no longer needed ide_pci_device_t.channels field. v2: * Fix issues noticed by Sergei: - correct code alignment in scc_pata.c - s/IDE_HFLAG_SINGLE/~IDE_HFLAG_SINGLE/ in serverworks.c Acked-by: NSergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: NBartlomiej Zolnierkiewicz <bzolnier@gmail.com>

After reworking the code responsible for selecting the best DMA transfer mode it is now possible to add generic ide_tune_dma() helper. Convert some IDE PCI host drivers to use it (the ones left need more work). Signed-off-by: NBartlomiej Zolnierkiewicz <bzolnier@gmail.com>

Depends on the "ide: fix UDMA/MWDMA/SWDMA masks" patch. * add ide_hwif_t.udma_filter hook for filtering UDMA mask (use it in alim15x3, hpt366, siimage and serverworks drivers) * add ide_max_dma_mode() for finding best DMA mode for the device (loosely based on some older libata-core.c code) * convert ide_dma_speed() users to use ide_max_dma_mode() * make ide_rate_filter() take "ide_drive_t *drive" as an argument instead of "u8 mode" and teach it to how to use UDMA mask to do filtering * use ide_rate_filter() in hpt366 driver * remove no longer needed ide_dma_speed() and *_ratemask() * unexport eighty_ninty_three() v2: * rename ->filter_udma_mask to ->udma_filter [ Suggested by Sergei Shtylyov <sshtylyov@ru.mvista.com>. ] v3: * updated for scc_pata driver (fixes XFER_UDMA_6 filtering for user-space originated transfer mode change requests when 100MHz clock is used) Signed-off-by: NBartlomiej Zolnierkiewicz <bzolnier@gmail.com>

* add ide_set_dma() helper and make ide_hwif_t.ide_dma_check return -1 when DMA needs to be disabled (== need to call ->ide_dma_off_quietly) 0 when DMA needs to be enabled (== need to call ->ide_dma_on) 1 when DMA setting shouldn't be changed * fix IDE code to use ide_set_dma() instead if using ->ide_dma_check directly v2: * updated for scc_pata Signed-off-by: NBartlomiej Zolnierkiewicz <bzolnier@gmail.com>

* 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: NBartlomiej Zolnierkiewicz <bzolnier@gmail.com>

* atiixp: if DMA can't be used atiixp_config_drive_for_dma() should return 0, atiixp_dma_check() will tune the correct PIO mode anyway * jmicron: if DMA can't be used config_chipset_for_dma() should return 0, micron_config_drive_for_dma() will tune the correct PIO mode anyway config_jmicron_chipset_for_pio(drive, !speed) doesn't program device transfer mode for speed != 0 (only wastes some CPU cycles on ide_get_best_pio_mode() call) so remove it * triflex: if DMA can't be used triflex_config_drive_for_dma() should return 0, triflex_config_drive_xfer_rate() will tune correct PIO mode anyway Above changes also fix (theoretical) issue when ->speedproc fails to set device transfer mode (i.e. when ide_config_drive_speed() fails to program it) but one of DMA transfer modes is already enabled on the device by the BIOS. In such scenario ide_dma_enable() will incorrectly return true statement and ->ide_dma_check will try to enable DMA on the device. Signed-off-by: NBartlomiej Zolnierkiewicz <bzolnier@gmail.com>

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!
