Message-ID: <64bb37e0912250122n4e0e1842q88c0dad7e99ec6a7@mail.gmail.com> Date: Fri, 25 Dec 2009 10:22:17 +0100 From: Torsten Kaiser <just.for.lkml@...glemail.com> To: linux-kernel@...r.kernel.org Cc: Jeff Garzik <jgarzik@...ox.com>, linux-ide@...r.kernel.org Subject: MSI broken in libata? As reported in http://lkml.org/lkml/2009/12/19/82 the new MSI support for sata_sil24 does not work for me. This is still the same with 2.6.33-rc2. Why I think, this might be a problem within libata: * other drivers can use MSI successful on my system (tg3, radeon, hda-intel) * happens both in sata_sil24 and sata_nv * the count in /proc/interrupts increases for the MSIs assigned to sata_sil24/sata_nv, so interrupt delivery seems to work * only writing seems to fail These are the changes in /proc/interrupts: Normal boot, without additional cmdline options: - 4: 0 0 96 174 IO-APIC-edge serial - 19: 18058 2 3 4738 IO-APIC-fasteoi sata_sil24, bttv0, Bt87x audio - 21: 0 0 0 0 IO-APIC-fasteoi sata_nv - 22: 0 0 0 0 IO-APIC-fasteoi sata_nv - 23: 872 357 4 1514 IO-APIC-fasteoi sata_nv, ohci_hcd:usb2 - 29: 4 405 0 140 PCI-MSI-edge HDA Intel - 30: 0 0 0 3 PCI-MSI-edge eth0 - 31: 3354 0 0 38 PCI-MSI-edge eth1 Boot with sata_nv.msi=1 and sata_sil24.msi=1, only booted into a rescue shell, thats why serial and eth0+1 are missing: + 19: 0 0 0 1 IO-APIC-fasteoi bttv0, Bt87x audio + 23: 0 0 5 13 IO-APIC-fasteoi ohci_hcd:usb2 + 29: 0 0 0 73 PCI-MSI-edge sata_sil24 + 30: 0 0 0 2590 PCI-MSI-edge sata_nv + 31: 0 0 0 0 PCI-MSI-edge sata_nv + 32: 0 0 0 0 PCI-MSI-edge sata_nv + 33: 0 0 0 89 PCI-MSI-edge HDA Intel Attached is the output from lspci -vv from a normal boot and from a boot with MSI enabled for both libata drivers. The errors messages from libata and other information about my system can be found in http://lkml.org/lkml/2009/12/19/82 ,or just ask if you need to know something else. Here are the differences from the lspci-outputs: lspci-vv-rc2.txt: complete, normal boot lspci-vv-rc2.msi.txt: init=/bin/sash, MSI for sata_sil24+sata_nv, network cards not initialised --- lspci-vv-rc2.txt 2009-12-25 00:11:19.992078760 +0100 +++ lspci-vv-rc2.msi.txt 2009-12-25 00:04:26.713756803 +0100 @@ -1,631 +1,586 @@ 00:04.0 IDE interface: nVidia Corporation MCP55 IDE (rev a1) (prog-if 8a [Master SecP PriP]) Subsystem: ASUSTeK Computer Inc.
