From ab1e39e20b19b7b84b07d34314a28a8e3fe44287 Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Mon, 21 May 2007 14:52:49 +0100 Subject: [PATCH] pata_hpt366: Enable bits are unreliable so don't use them Various people had problems with both old and new IDE when hpt366 enable bits started getting honoured. It turns out they are not reliable so don't rely on them Signed-off-by: Alan Cox Signed-off-by: Jeff Garzik --- drivers/ata/pata_hpt366.c | 28 +--------------------------- 1 file changed, 1 insertion(+), 27 deletions(-) diff --git a/drivers/ata/pata_hpt366.c b/drivers/ata/pata_hpt366.c index c6c8a8bb06d08..0c9cb60907117 100644 --- a/drivers/ata/pata_hpt366.c +++ b/drivers/ata/pata_hpt366.c @@ -220,32 +220,6 @@ static int hpt36x_cable_detect(struct ata_port *ap) return ATA_CBL_PATA80; } -static int hpt36x_pre_reset(struct ata_port *ap, unsigned long deadline) -{ - static const struct pci_bits hpt36x_enable_bits[] = { - { 0x50, 1, 0x04, 0x04 }, - { 0x54, 1, 0x04, 0x04 } - }; - struct pci_dev *pdev = to_pci_dev(ap->host->dev); - - if (!pci_test_config_bits(pdev, &hpt36x_enable_bits[ap->port_no])) - return -ENOENT; - - return ata_std_prereset(ap, deadline); -} - -/** - * hpt36x_error_handler - reset the hpt36x bus - * @ap: ATA port to reset - * - * Perform the reset handling for the 366/368 - */ - -static void hpt36x_error_handler(struct ata_port *ap) -{ - ata_bmdma_drive_eh(ap, hpt36x_pre_reset, ata_std_softreset, NULL, ata_std_postreset); -} - /** * hpt366_set_piomode - PIO setup * @ap: ATA interface @@ -351,7 +325,7 @@ static struct ata_port_operations hpt366_port_ops = { .freeze = ata_bmdma_freeze, .thaw = ata_bmdma_thaw, - .error_handler = hpt36x_error_handler, + .error_handler = ata_bmdma_error_handler, .post_internal_cmd = ata_bmdma_post_internal_cmd, .cable_detect = hpt36x_cable_detect, -- 2.39.5
