| | | | | | | | | | | | | | | | | | | | | | | Majority of host drivers using IDE PCI layer set drive->autotune, the only exceptions are: generic.c ns87415.c rz1000.c trm290.c * no ->set_pio_mode method it821x.c: * if memory allocation fails drive->autotune won't be set (but there also won't be ->set_pio_mode method in such case) piix.c: * MPIIX controller (no ->init_hwif method so also no ->set_pio_mode method) However if there is no ->set_pio_mode method there are no changes in behavior w.r.t.

Use it as an upper limit when finding the best DMA for device/host. * Rename ide_max_dma_mode() to ide_find_dma_mode() and at the same time add ide_max_dma_mode() wrapper which passes XFER_UDMA_6 as a requested mode to ide_find_dma_mode(). Also add inline ide_find_dma_mode() version for CONFIG_BLK_DEV_IDEDMA=n case. * Pass requested transfer mode from ide_find_dma_mode() to ide_get_mode_mask() to avoid false warning from eighty_ninty_three(). * Use ide_find_dma_mode() to limit the user requested transfer mode in ide_rate_filter(). Also limit the requested mode by host max PIO mode. Above changes make ide_rate_filter() to: * Clip desired transfer mode down if it is invalid (values 0x0F, 0x13-0x19 and 0x25-0x39, values > 0x46 were already clipped down, same for values 0x25-0x39 but iff UDMA was not supported by the host). * Clip desired transfer mode down if it is currently unsupported by IDE core (PIO6 and MWDMA3-4, the latter were already clipped down but iff UDMA was not supported by the host). * Clip desired transfer mode down according to the host capabilities (UDMA modes were already clipped down but MWDMA/SWDMA/PIO weren't, also ->atapi_dma flag was not respected). * Clip desired transfer mode down according to the device capabilities (except PIO modes for now which require mode work) - shouldn't be a problem since ide_set_xfer_rate() is called _after_ device has accepted given transfer mode. and also result in a number of host driver specific bugfixes: * icside - clip unsupported PIO5 mode down -

* PCI: Change all drivers to use pci_device->revisionAuke Kok2007-07-121-15/+5
| | | | | | | | | | | | | | | | | | | | Instead of all drivers reading pci config space to get the revision ID, they can now use the pci_device->revision member. This exposes some issues where drivers where reading a word or a dword for the revision number, and adding useless error-handling around the read. Some drivers even just read it for no purpose of all. In devices where the revision ID is being copied over and used in what appears to be the equivalent of hotpath, I have left the copy code and the cached copy as not to influence the driver's performance. Compile tested with make all{yes,mod}config on x86_64 and i386.

| | | | | | | | | | | | | | | | | | | | | | This patch allows users to override both host and device side cable detection with "ideX=ata66" kernel parameter. Thanks to this it should be now possible to use UDMA > 2 modes on systems (laptops mainly) which use short 40-pin cable instead of 80-pin one. Next patches add automatic detection of some systems using short cables. Changes: * Rename hwif->udma_four to hwif->cbl and make it u8. * Convert all existing users accordingly (use ATA_CBL_* defines while at it). * Add ATA_CBL_PATA40_SHORT support to ide-iops.c:eighty_ninty_three(). * Use ATA_CBL_PATA40_SHORT for "ideX=ata66" kernel parameter.

| | | | | | | | | | | | | | | | | | | Fix minor coding mistake in the HPT36x PCI clock detection code noticed by Bartlomiej Zolnierkiewicz -- it always reported 33 MHz due to the missing 'break' statements. This, however, most probably never mattered -- in fact, I was thinking of removing the 25/40 MHz cases completely since HPT36x BIOSes didn't seem to set any other value than 7 into the 'cmd_high_time' field, i.e. supported only 33 MHz PCI. Note that in the original driver there was another bug: 25 and 40 MHz cases were interchanged. Since the 'cmd_high_time' field is in units of PCI clocks, a lower clock count just *cannot* correspond to a higher frequency, i. e. it should be 5 for 25 MHz PCI and 9 for 40 MHz PCI, not the other way around.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Finally, rework the driver init. code to correctly handle all the chip variants HighPoint has created so far. This should cure the rest of the timing issues in the driver (especially, on 66 MHz PCI) caused by the HighPoint's habit of switching the base DPLL clock with every new revision of the chips... - switch to using the enumeration type to differ between the numerous chip variants, matching PCI device/revision ID with the chip type early, at the init_setup stage; - extend the hpt_info structure to hold the DPLL and PCI clock frequencies, stop duplicating it for each channel by storing the pointer in the pci_dev structure: first, at the init_setup stage, point it to a static "template" with only the chip type and its specific base DPLL frequency, the highest supported DMA mode, and the chip settings table pointer filled, then, at the init_chipset stage, allocate per-chip instance and fill it with the rest of the necessary information; - get rid of the constant thresholds in the HPT37x PCI clock detection code, switch to calculating PCI clock frequency based on the chip's base DPLL frequency; - switch to using the DPLL clock and enable UltraATA/133 mode by default on anything newer than HPT370/A; - fold PCI clock detection and DPLL setup code into init_chipset_hpt366(), unify the HPT36x/37x setup code and the speedproc handlers by joining the register setting lists into the table indexed by the clock selected; - add enablebits for all the chips to avoid touching disabled channels (though the HighPoint BIOS seem to only disable the primary one on HPT371/N); - separate the UltraDMA and MWDMA masks there to avoid changing PIO timings when setting an UltraDMA mode in hpt37x_tune_chipset(). This version has been tested on HPT370/302/371N. Thanks to Alan for the inspiration. Hopefully, his libata driver will also benefit from the work done on this "obsolete" driver...
