2009-06-07pdc202xx_old: fix resetproc() methodSergei Shtylyov1-14/+5
pdc202xx_reset() calls pdc202xx_reset_host() twice, for both channels, while that function actually twiddles the single, shared software reset bit -- the net effect is a duplicated reset and horrendous 4 second delay happening not only on a channel reset but also when dma_lost_irq() and dma_clear() methods are called. Fold pdc202xx_reset_host() into pdc202xx_reset(), fix printk(), and move it before the actual reset...

2009-06-07pdc202xx_old: fix 'pdc20246_dma_ops'Sergei Shtylyov1-2/+1
Commit ac95beedf8bc97b24f9540d4da9952f07221c023 (ide: add struct ide_port_ops (take 2)) erroneously converted the driver's dma_timeout() and dma_lost_irq() methods to call the driver's resetproc() method regardless of whether it was defined for this specific controller while it hadn't been defined and hence called for PDC20246. So the dma_clear() method, the successor of dma_timeout(), shouldn't exist and the dma_lost_irq() method should be standard for PDC20246.

It is possible for ide-cd to ignore ide_error()'s return value under some circumstances. Workaround it in ide_intr() and ide_timer_expiry() by checking if there is a device/port reset pending currently.

2009-05-22ide: fix 40-wire cable detection for TSST SH-S202* ATAPI devices (v2)Bartlomiej Zolnierkiewicz1-4/+17
Since 2.6.26 we support UDMA66 on ATAPI devices requiring IVB quirk: commit 8588a2b732928b343233af9b1855705b8286bed4 ("ide: add SH-S202J to ivb_list[]") We also later added support for more such devices in: commit e97564f362a93f8c248246c19828895950341252 ("ide: More TSST drives with broken cable detection") and in: commit 3ced5c49bd2d1f2c7f769e3a54385883de63a652 ("ide: add TSSTcorp CDDVDW SH-S202H to ivb_list[]") It turns out that such devices lack cable detection altogether (which in turn results in incorrect detection of 40-wire cables by our current cable detection strategy) so always handle them by trusting host-side cable detection only. v2: Model detection fixup from Martin.

Bugfixes noted by checking the code against the controller documentation (TI document number SPRUE21): - Remove declarations for eight non-existent registers (!); and remove accesses to two of them. - Remove access to various non-existent bitfields in some of the registers which *do* exist (those fields must-be-zero). - Provide comment to replace bogus reset logic (removed above, it relied on non-existent bitfields). Resets require GPIO help; this driver doesn't currently know about that. With some minor cleanup: relocate a comment, avoid an extra lookup of the PIO timings.

2009-04-22palm_bk3710: UDMA performance fixDavid Brownell1-14/+12
Fix UDMA throughput bug: tCYC averages t2CYCTYP/2, but the code previously assumed it was the same as t2CYCTYP. (That is, it was using just one clock edge, not both.) Move the table's type declaration so it's adjacent to the table, making it more clear what those numbers mean. On one system this change increased throughput by almost 4x: UDMA/66 sometimes topped 23 MB/sec (on a drive known to do much better). On another system it was around a 10% win (UDMA/66 up to 7+ MB/sec). The difference might be caused by the ratio between memory and IDE clocks. In the system with large speedup, this was exactly 2 (as a workaround for a rev 1.1 silicon bug). The other system used a more standard ratio of 1.63 (and rev 2.1 silicon) ... clock domain synch might have some issues, they're not unheard-of.

2009-04-08ide: falconide/q40ide - Use __ide_mm_{in,out}sw() for dataGeert Uytterhoeven2-8/+19
Both of commits f94116aeec7a299640dd692128e1d22178affa8d ("ide: cleanup <asm-m68k/ide.h>") and 15a453a955f89f6545118770c669b52e925368bd ("ide: include <asm/ide.h> only when needed") break falconide: | Uniform Multi-Platform E-IDE driver | ide: Falcon IDE controller | Probing IDE interface ide0... | hda: Sarge m68k, ATA DISK drive | ide0 at 0xfff00000 on irq 15 (serialized) | ide-gd driver 1.18 | hda: max request size: 128KiB | hda: 2118816 sectors (1084 MB) w/256KiB Cache, CHS=2102/16/63 | hda:<4>hda: lost interrupt This happens because falconide relies on {in,out}sw() being redefined in <asm/ide.h>, as included by <linux/ide.h>, which is no longer the case. Use __ide_mm_{in,out}sw() from <asm/ide.h> instead, just like ide_{in,out}put_data() do. The same problem seems to exist in q40ide.

2009-04-08ide: Fix host drivers that need IRQF_SHAREDGeert Uytterhoeven1-0/+1
commit 255115fb35f80735c21a1cbe9809e9795a3af26e ("ide: allow host drivers to specify IRQ flags") added irq_flags fields to struct ide_port_info and struct ide_host. Drivers can now set ide_port_info.irq_flags = IRQF_SHARED, while init_irq() passes ide_host.irq_flags to request_irq(). Unfortunately ide_host.irq_flags is never set, causing (on ARAnyM): | Uniform Multi-Platform E-IDE driver | ide: Falcon IDE controller | Probing IDE interface ide0... | hda: Sarge m68k, ATA DISK drive | init_irq: sa = 0 | ide0: disabled, unable to get IRQ 15 | ide0: failed to initialize IDE interface | ide0: disabling port Solve this by copying ide_port_info.irq_flags to ide_host.irq_flags in ide_host_alloc(). This bug probably affects the following IDE host drivers: - buddha - delkin_cb - falconide - gayle - ide-cs - macide - q40ide - scc_pata - sgiioc4 Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
