- From: b.sander
- Subject: [PATCH] pci: IDE fix
- These are standard probing messages when using pdc202xx_old:
- pdc202xx_old 0000:00:01.0: IDE controller (0x105a:0x0d30 rev 0x02)
- PCI: Enabling device 0000:00:01.0 (0004 -> 0007)
- PCI: Fixing up device 0000:00:01.0
- 0000:00:01.0: (U)DMA Burst Bit DISABLED Primary PCI Mode Secondary PCI Mode.
- 0000:00:01.0: FORCING BURST BIT 0x00->0x01 ACTIVE
- pdc202xx_old 0000:00:01.0: 100% native mode on irq 6
- With the default MAX_HWIFS value after above we get:
- ide2: BM-DMA at 0x0400-0x0407
- ide3: BM-DMA at 0x0408-0x040f
- Probing IDE interface ide2...
- hde: CF500, CFA DISK drive
- As you can see it's ide2 + ide3 and hde.
- With this patch applied we get:
- ide0: BM-DMA at 0x0400-0x0407
- ide1: BM-DMA at 0x0408-0x040f
- Probing IDE interface ide0...
- hda: CF500, CFA DISK drive
- This fixes OpenWrt ticket #7061: https://dev.openwrt.org/ticket/7061
