Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hi all, I'm not subscribed to the list so please CC me on replies/thread this might produce, thanks. I recently bought a new PC with ATI IXP chipset for sound, video, ide. sound is working correctly but IDE was really slow (no dma) until I recompiled my Fedora core 3 kernel, changing include/linux/pci_ids.h to have my chipset recognized as a ati_ixp one. here is the result of lspci on the computer: 00:00.0 Host bridge: ATI Technologies Inc: Unknown device 7833 00:01.0 PCI bridge: ATI Technologies Inc: Unknown device 7838 00:13.0 USB Controller: ATI Technologies Inc: Unknown device 4367 (rev 01) 00:13.1 USB Controller: ATI Technologies Inc: Unknown device 4368 (rev 01) 00:13.2 USB Controller: ATI Technologies Inc: Unknown device 4365 (rev 01) 00:14.0 SMBus: ATI Technologies Inc: Unknown device 4363 (rev 03) 00:14.1 IDE interface: ATI Technologies Inc: Unknown device 4369 (rev 01) 00:14.3 ISA bridge: ATI Technologies Inc: Unknown device 436c (rev 01) 00:14.4 PCI bridge: ATI Technologies Inc: Unknown device 4362 (rev 01) 00:14.5 Multimedia audio controller: ATI Technologies Inc: Unknown device 4361 (rev 03) 01:05.0 VGA compatible controller: ATI Technologies Inc Radeon 9100 PRO IGP 02:06.0 Communication controller: Conexant HSF 56k HSFi Modem (rev 01) 02:0b.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10) To have the chipset recognized, I just changed the line: /* ATI IXP Chipset */ #define PCI_DEVICE_ID_ATI_IXP_IDE 0x4349 with this one: #define PCI_DEVICE_ID_ATI_IXP_IDE 0x4369 after that, dmesg says kernel recognized the chip and DMA is working, hdparm -t changed from 8MB/s to 47MB/s, nice ! messaged during boot (dmesg): Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2 ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx ATIIXP: IDE controller at PCI slot 0000:00:14.1 ACPI: PCI interrupt 0000:00:14.1[A] -> GSI 10 (level, low) -> IRQ 10 ATIIXP: chipset revision 1 ATIIXP: not 100% native mode: will probe irqs later ide0: BM-DMA at 0xf000-0xf007, BIOS settings: hda:DMA, hdb:pio ide1: BM-DMA at 0xf008-0xf00f, BIOS settings: hdc:DMA, hdd:DMA Probing IDE interface ide0... hda: ST380011A, ATA DISK drive Using cfq io scheduler ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 Probing IDE interface ide1... hdc: HL-DT-ST DVDRAM GSA-4082B, ATAPI CD/DVD-ROM drive hdd: DVD-ROM BDV316E, ATAPI CD/DVD-ROM drive ide1 at 0x170-0x177,0x376 on irq 15 I guess this could be taken care of in a future release of the kernel, or maybe you need more documentation from Ati on what have changed between these 2 releases of the chip ? I am volunteering to test the patches that might be produced to make this hardware function correctly, if needed ... Regards, Pascal Lengard
