No new dmesg info when insert/eject maybe indicate the pciehp driver never received the interrupt or there is no bit set about Presence Detect Changed here. Or there is debug info like : pcie_isr: intr_loc %x at least. eSATA card SiI 3132, no XHCI, hotplug only got problem with 3.9-rc1? or both at 3.7 3.8?

What is the purpose of having PresDet+ on the Status: line and PresDet- on the Changed: line? Why isn't LinkState+ cleared on the Changed: line as well at least? Sometimes I was even thinking that maybe some broken code in hotplug changes LinkState instead of the PresDet on the Changed: line. > >> >> >> I re-plugged the card and ejected several times while the while loops >> collecting lspci and slot_status via the setpci shell command harvested >> data.

But it seems it is received - per the Status: line. What the driver does with the PresDet value on the Changed: line should not matter in this regard, right? > Or there is debug info like : > pcie_isr: intr_loc %x at least. Sorry, this does not help me. Would you please modify the setpci shell command to print more values in the while loop? Or even better, provide me with a debug patch showing whenever a value in those registers and additionally derived variables is changed (0000, 0040, 0100, 0108, 0140, 0148)? In the "Dell Vostro 3550: pci_hotplug+acpiphp require 'pcie_aspm=force' on kernel command-line for hotplug to work" thread I already reported how pciehp hotplug under same 3.9-rc1 like here works for the eSATA card: pciehp hotplug: [ 211.879397] sata_sil24 0000:11:00.0: enabling device (0100 -> 0103) coldplug+(unnoticed ejects+inserts)+rmmod sata_sil24: [ 605.818923] sata_sil24 0000:11:00.0: enabling device (0000 -> 0003) The cold-plugged eSATA card gave somewhat different output during coldboot compared to those lines when hotplug happens, so I am not able to compare the output directly. In the mentioned tar.bz2 archive you could have found yourself in dmesg_after_rmmod_and_modprobe_sata_sil24.txt file: [ 9.662550] sata_sil24 0000:11:00.0: version 1.1 [ 9.665780] scsi6 : sata_sil24 [ 9.667526] scsi7 : sata_sil24 [ 9.668028] ata7: SATA max UDMA/100 host m128@0xf6c84000 port 0xf6c80000 irq 19 [ 9.668032] ata8: SATA max UDMA/100 host m128@0xf6c84000 port 0xf6c82000 irq 19 Not much verbose on coldboot, isn't it? > > eSATA card SiI 3132, no XHCI, hotplug only got problem with 3.9-rc1? or both at 3.7 3.8? In earlier times I never fiddled xhci disabled under 3.7 nor 3.8. Second, I had to use acpiphp instead due to the breakage around 3.5. But you might compare with locks held by sata_sil24 in dmesg files in "3.7.10: acpiphp with pcie_aspm=off and eSATA card Sil 3132" thread. That could give you a clue. Maybe. ;-) Martin -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
Hi Martin, From your diff info, maybe we can analyze this problem step by step. 1、According to your diff info about first eject and first hot add, the pci device 11:00.0 Mass storage controller was removed and was added ok at pci device level; 2、The main problem is 11:00.0 Mass storage controller can not bind its driver normally, right? 3、According to diff info about first hotadd and coldplug, the mainly diff is > + Region 0: Memory at f6c84000 (64-bit, non-prefetchable) [disabled] [size=128] > + Region 2: Memory at f6c80000 (64-bit, non-prefetchable) [disabled] [size=16K] > + Region 4: I/O ports at c000 [disabled] [size=128] and MaxReadReq 4096 bytes ----> MaxReadReq 512 bytes So maybe we can try to find why the memory range was disabled after hot add. Martin, can you provide /proc/iomem info when the system bootup, after first eject and first hot-add? I suspect the driver release its MMIO successfully after first eject. Thanks! Yijing.

Here is a reasonably complete diff between a coldplugged state of the same card and after a hotplug. In dmesg pciehp complained upon its loading that Cache Line Size 64 is not supported so maybe the below difference is a direct result of that? Similarly, MaxReadReq is different and I bet the lines + Region 0: Memory at f6c84000 (64-bit, non-prefetchable) [disabled] [size=128] + Region 2: Memory at f6c80000 (64-bit, non-prefetchable) [disabled] [size=16K] + Region 4: I/O ports at c000 [disabled] [size=128] actually mean the card is left disabled. Then, I am not surprised nothing is shown upon its hotplug insert/eject in dmesg. ;-) In this particular setup I don't think we are facing a PresDet issue. Either, the value is overwritten by some other process, or the bug is somewhere else. --- lspci_loop.23:58:26 2013-03-11 23:58:26.000000000 +0100 +++ lspci_loop.23:59:10 2013-03-11 23:59:10.000000000 +0100 @@ -439,7 +439,7 @@ I/O behind bridge: 0000c000-0000dfff Memory behind bridge: f6c00000-f7cfffff Prefetchable memory behind bridge: 00000000f0000000-00000000f10fffff - Secondary status: 66MHz- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- <SERR- <PERR- + Secondary status: 66MHz- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort+ <SERR- <PERR- BridgeCtl: Parity- SERR- NoISA- VGA- MAbort- >Reset- FastB2B- PriDiscTmr- SecDiscTmr- DiscTmrStat- DiscTmrSERREn- Capabilities: [40] Express (v2) Root Port (Slot+), MSI 00 @@ -459,7 +459,7 @@ SltCtl: Enable: AttnBtn- PwrFlt- MRL- PresDet- CmdCplt- HPIrq- LinkChg- Control: AttnInd Unknown, PwrInd Unknown, Power- Interlock- SltSta: Status: AttnBtn- PowerFlt- MRL- CmdCplt- PresDet+ Interlock- - Changed: MRL- PresDet- LinkState- + Changed: MRL- PresDet- LinkState+ RootCtl: ErrCorrectable- ErrNon-Fatal- ErrFatal- PMEIntEna- CRSVisible- RootCap: CRSVisible- RootSta: PME ReqID 0000, PMEStatus- PMEPending- @@ -478,11 +478,11 @@ Status: D0 NoSoftRst- PME-Enable- DSel=0 DScale=0 PME- Kernel driver in use: pcieport 00: 86 80 1e 1c 07 00 10 00 b5 00 04 06 10 00 81 00 -10: 00 00 00 00 00 00 00 00 00 11 16 00 c0 d0 00 00 +10: 00 00 00 00 00 00 00 00 00 11 16 00 c0 d0 00 20 20: c0 f6 c0 f7 01 f0 01 f1 00 00 00 00 00 00 00 00 30: 00 00 00 00 40 00 00 00 00 00 00 00 0a 04 10 00 40: 10 80 42 01 00 80 00 00 00 00 10 00 12 3c 12 08 -50: 40 00 11 70 60 b2 3c 00 00 00 40 00 00 00 00 00 +50: 40 00 11 70 60 b2 3c 00 00 00 40 01 00 00 00 00 60: 00 00 00 00 16 00 00 00 00 00 00 00 00 00 00 00 70: 01 00 01 00 00 00 00 00 00 00 00 00 00 00 00 00 80: 05 90 00 00 00 00 00 00 00 00 00 00 00 00 00 00 @@ -799,14 +799,13 @@ 11:00.0 Mass storage controller: Silicon Image, Inc.

Hi, I cold-booted a computer with the card inserted before power-on and collected lspci output and express card slot status every second. Then I tried eject and hotplug inserts and it appearts the card is not detected, actually maybe pciehp is not even suppoosed to work in this case as the slot was occupied during boot. But let me come to it later. I noted the following on the very first eject of the so far cold-plugged card that lspci properly reports PresDet change on the Changed: line. The only time I ever saw it. ;-) However, for any following inserts and ejects the value is not updated but slot status bits are updated. I had BIOS defaults loaded and additionally, disabled MediaCardReader. The slot status bits read by setpci were changing in this path: card in slot and cold boot 0040 -> eject 0100 hotplug insert -> 0140 eject -> 0100 hotplug insert -> 0140 eject -> 0100 Sadly, although the very first eject was notified the sata_sila24 neither did "release" the device nor did it complain that it suddenly disappeared. That was so far always in dmesg output (like for example): [ 251.632928] sata_sil24 0000:11:00.0: PME# disabled [ 251.636498] sata_sil24: IRQ status == 0xffffffff, PCI fault or device removal? I re-plugged the card and ejected several times while the while loops collecting lspci and slot_status via the setpci shell command harvested data. Still, in dmesg there was nothing logged regarding card insert/eject. Eventually, I tried rmmod sata_sil24 (did NOT need 'rmmod -f') and that did log something new.

It does NOT contain the usual debug info spanning several lines and it only said: [ 2.109629] pci_hotplug: PCI Hot Plug PCI Core version: 0.5 [ 2.110225] pciehp: pcie_port_service_register = 0 [ 2.110226] pciehp: PCI Express Hot Plug Controller Driver version: 0.4 If that is intentional the driver should complain loudly. Please educate me what those "[virtual] Expansion ROM's" were in lspci above and whether those "[disabled]" memory ranges relate to that as well. If the card is not thought to be present or just not recognized ... why is that printed in lspci at all? Similarly, what can you tell me if lspci output shows only: Latency: 0 or even lacks the whole "Latency" line altoghether, is that also a disabled device? I believe in working cases there is "Latency: 0, Cache Line Size: 64 bytes" instead.
