Hey guys,
Booted 2.6.35 + my drm-next tree this morning, happened with -rc6. Now
I changed graphics cards this morning, and my 2.6.32 based enterprise
kernels are booting fine, and I haven't had much time to bisect this,
but I thought it might be interesting to you guys. I've booted my
kernel on other machines with no problems which is why I suspect its
not a drm-next issue and is a real 2.6.35 issue.
I've attached the full dmesg up to the oops + lspci -vvv from this machine.
Let me know if you want any other info, and I'll try and get some
bisecting going on in the meanwhile.
Dave.
Now I can't swear this isn't something in my drm-next tree, but
[drm] radeon kernel modesetting enabled.

As I read the code. First we will do a generic isa setup, marking the interrupt ioapic table entry edge triggered. Then we will do a pci setup for any pin we use as pci, and then we will set pin_programmed stopping us from updating the pin any more, during setup. For the common case I think we still do the right thing, even now, for these broken bios tables. There is likely an uncommon case for which something like your shared_legacy_irq deserves to be used, especially at it preserves our well tested historical behavior.

So far you have not presented a credible scenario where this would affect anything in real life except the user visible irq number. Will you please stop, think, and describe what is going on clearly and how you expect this patch to affect anything, and please stop selling this patch as the solution to all of the world's ills. You are being sloppy and wasting everyone's time. This patch definitely does not solve Dave Airlie's problem. That was clearly caused by a (ACPI being disabled compared to the test case) and a bad BIOS provided MP table with an invalid apic_id, and our attempt to lookup the ioapic and failed. This patch doesn't have much of a chance of solving the no VGA output on boot problem. It comes much much to late affect anything there. > also > for the io apic out of order system: > <6>ACPI: IOAPIC (id[0x10] address[0xfecff000] gsi_base[0]) > <6>IOAPIC[0]: apic_id 16, version 0, address 0xfecff000, GSI 0-2 > <6>ACPI: IOAPIC (id[0x0f] address[0xfec00000] gsi_base[3]) > <6>IOAPIC[1]: apic_id 15, version 0, address 0xfec00000, GSI 3-38 > <6>ACPI: IOAPIC (id[0x0e] address[0xfec01000] gsi_base[39]) > <6>IOAPIC[2]: apic_id 14, version 0, address 0xfec01000, GSI 39-74 > <6>ACPI: INT_SRC_OVR (bus 0 bus_irq 1 global_irq 4 dfl dfl) > <6>ACPI: INT_SRC_OVR (bus 0 bus_irq 0 global_irq 5 dfl dfl) > <6>ACPI: INT_SRC_OVR (bus 0 bus_irq 3 global_irq 6 dfl dfl) > <6>ACPI: INT_SRC_OVR (bus 0 bus_irq 4 global_irq 7 dfl dfl) > <6>ACPI: INT_SRC_OVR (bus 0 bus_irq 6 global_irq 9 dfl dfl) > <6>ACPI: INT_SRC_OVR (bus 0 bus_irq 7 global_irq 10 dfl dfl) > <6>ACPI: INT_SRC_OVR (bus 0 bus_irq 8 global_irq 11 low edge) > <6>ACPI: INT_SRC_OVR (bus 0 bus_irq 9 global_irq 12 dfl dfl) > <6>ACPI: INT_SRC_OVR (bus 0 bus_irq 12 global_irq 15 dfl dfl) > <6>ACPI: INT_SRC_OVR (bus 0 bus_irq 13 global_irq 16 dfl dfl) > <6>ACPI: INT_SRC_OVR (bus 0 bus_irq 14 global_irq 17 low edge) > <6>ACPI: INT_SRC_OVR (bus 0 bus_irq 15 global_irq 18 dfl dfl) > > after this patch will get > > apic0, pin0, GSI 0: irq 0+75 > apic0, pin1, GSI 1: irq 1+75 > apic0, pin2, GSI 2: irq 2 > apic1, pin0, GSI 3: irq 3+75 > apic1, pin5, GSI 8: irq 8+75 > apic1, pin10,GSI 13: irq 13+75 > apic1, pin11,GSI 14: irq 14+75 If your description of what this patch will do is correct we very definitely do not want this patch. For the previously mentioned acpi tables we want GSI17 -> apic1, pin 14 -> irq 14. Not that your description is correct, but a buggy description is an equally valid reason to reject this incarnation of the patch. > because mp_config_acpi_legacy_irqs will put apic0, pin2, irq2 in mp_irqs... > so pin_2_irq_legacy will report 2. > irq_to_gsi will still report 2. so it is right. > gsi_to_irq will report 2. > > for GSI 0, 1, 3, 8, 13, 14: still right as before. YH you have a point that a certain class of buggy firmware exists, that reports some ioapic pins as both edge triggered ISA irqs and level triggered PCI irqs, and assigning different irqs to the same ioapic pin is confusing and suboptimal. In practice I don't see that behavior affecting how we program that pin, especially since I don't expect any bios that exports that setup to actually use the ISA irq. So we should just have an unused irq number. A clean solution would be to scrub the input from the MP table before we attempt to use of it, instead of scrubbing the data as we use in code paths like pin_2_irq. Just touching pin_2_irq is certainly an incomplete solution because you have not resolved if the pins should be edge or level triggered, and what polarity we should be sampling them at. Until I see a plausible scenario where not handling buggy MP tables exactly as we have done in the past I don't see hacks like you are proposing making much sense at all.

Oh wow, I totally missed I had ACPI off on this build, I turned it off a few kernels back to test the build didn't break, and forgot to turn it back on. So clearly my mptable is just busted and we can probably move along, I'll rebuild/boot with ACPI now, and I think you can assume it works fine unless I get back to you.

LinuxBIOS should be ok, already have external devices to use pin above 15. Also your patch does cause kernel crash when acpi is disabled in virtualbox even there could be BIOS problem there. kernel before your patch does work in that conf.

The kernel should not crash obviously, so that's a bug that has to be addressed - or failing any timely resolution the original patch which introduced the regression [if it's a regression] needs to be reverted.

This looks roughly like the right approach. However I don't see what would force the ioapic entries before the intsrc entries in the table. Especially when the assumption is we are dealing with a buggy bios. > --- > arch/x86/kernel/mpparse.c | 44 +++++++++++++++++++++++++++++++++++++------- > 1 file changed, 37 insertions(+), 7 deletions(-) > > Index: linux-2.6/arch/x86/kernel/mpparse.c > =================================================================== > --- linux-2.6.orig/arch/x86/kernel/mpparse.c > +++ linux-2.6/arch/x86/kernel/mpparse.c > @@ -173,17 +173,17 @@ static int __init mp_irq_mpc_intsrc_cmp( > { > if (mp_irq->dstapic != m->dstapic) > return 1; > - if (mp_irq->type != m->type) > + if (mp_irq->dstirq != m->dstirq) > return 2; > - if (mp_irq->irqtype != m->irqtype) > + if (mp_irq->srcbus != m->srcbus) > return 3; > - if (mp_irq->irqflag != m->irqflag) > + if (mp_irq->type != m->type) > return 4; > - if (mp_irq->srcbus != m->srcbus) > + if (mp_irq->irqtype != m->irqtype) > return 5; > - if (mp_irq->srcbusirq != m->srcbusirq) > + if (mp_irq->irqflag != m->irqflag) > return 6; > - if (mp_irq->dstirq != m->dstirq) > + if (mp_irq->srcbusirq != m->srcbusirq) > return 7; > > return 0; > @@ -195,9 +195,39 @@ static void __init MP_intsrc_info(struct > > print_MP_intsrc_info(m); > > + /* > + * Assume BUS, and IOAPIC entries come first all before > + * INTSRC entries > + */ > + > + /* check if dstapic is right */ > + for (i = 0; i < nr_ioapics; i++) { > + if (mp_ioapics[idx].apicid == m->dstapic) > + break; > + } > + if (i == nr_ioapics) > + return; If we can make the algorithm two pass picking up the ioapic entries first this should be fine. > for (i = 0; i < mp_irq_entries; i++) { > - if (!mp_irq_mpc_intsrc_cmp(&mp_irqs[i], m)) > + int ret = mp_irq_mpc_intsrc_cmp(&mp_irqs[i], m); > + > + /* duplicated entries ? */ > + if (!ret) > return; > + > + /* same apic/pin, but different bus */ > + if (ret == 3) { > + /* overwrite wrong legacy one */ In practice your test of looking at mp_bus_not_pci is essentially what we do. I wonder if it could be made to be a test of polarity and edge mismatch instead. Also if we are ditching a non-duplicate intsrc we want to print a message so there is a chance of debugging things if our heuristic for fixing up broken BIOS's goes wrong, on some common configuration. > + if (test_bit(mp_irqs[i].srcbus, mp_bus_not_pci) && > + !test_bit(m->srcbus, mp_bus_not_pci)) { > + assign_to_mp_irq(m, &mp_irqs[mp_irq_entries]); That should be. > + assign_to_mp_irq(m, &mp_irqs[i]); > + return; > + } > + /* dump this legacy one */ > + if (!test_bit(mp_irqs[i].srcbus, mp_bus_not_pci) && > + test_bit(m->srcbus, mp_bus_not_pci)) > + return; > + } > } > > assign_to_mp_irq(m, &mp_irqs[mp_irq_entries]); Eric ^ permalink raw reply [flat|nested] 31+ messages in thread

No. I was thinking it would be nice if we could check the polarity and the irq trigger mode in this case. Unfortunately I don't think we have access to everything thing we need to perform that check this early. Eric ^ permalink raw reply [flat|nested] 31+ messages in thread

Which is a pretty bizarre thing to do, especially when bus 0 is pretty clearly PCI. That does sound like a buggy MP table. Eric ^ permalink raw reply [flat|nested] 31+ messages in thread

It appears we have a smoking gun: For some reason setup_IO_APIC_IRQS thinks we at least 2 io_apics, but we have only setup 1 io_apic. Since io_apics need a kmap entry accessing an apic that hasn't been setup will definitely give a page fault. It sounds like something is stomping nr_ioapics. From: 2.6.35-debuglog IOAPIC[0]: apic_id 8, version 17, address 0xfec00000, GSI 0-23 .... IOAPIC[1]: Set routing entry (0-16 -> 0x51 -> IRQ 16 Mode:1 Active:1) Can we get your System.map of the failing kernel (so we can see what is close to nr_ioapics), and could you add a print statement in arch/x86/kernel/apic/io_apic:setup_IO_APIC_irqs to print nr_ioapics? I would be surprised if drm changes could have affected this. Eric ^ permalink raw reply [flat|nested] 31+ messages in thread

I goofed reading that code. I saw setup_IO_APIC_irq and made the incorrect leap that said we came from setup_IO_APIC_irqs, when in fact we are coming from io_apic_set_pci_routing. So let's see can I figure out why we are getting a bad apic_id. For that I need to track back to pirq_enable_irq, which leads me to IO_APIC_get_PCI_irq_vector. The likely canidate is that we simply are not finding the apicid that is present in the mp_irqs entry that we decided to return. The patch below should add appropriate debugging and fix the lookup The real difference appears to be that acpi is disabled where it is not disabled in your reference kernel. Dave can you verify this fixes the oops for you? It would be nice if we didn't crash early in boot even without acpi present.
