Keyboard response, mouse movements, display refreshing etc. General input/display sluggishness. Did something break IRQ handling somewhere? I need to validate if this happens with X not running also if it is i915 related somehow.

There were a lot of changes to PCI and ACPI for 3.9. Probably best to each file a bug at bugzilla.kernel.org with: Last known good kernel version -- For both good and bad kernels (preferably as attachments) -- /proc/interrupts lsusb lspci dmesg and reply back with the bugzilla #. It may be necessary to bisect this problem. Regards, Peter Hurley PS - I know it can be difficult to get those things on the bad kernel. It's easier if you boot to console. ^ permalink raw reply [flat|nested] 39+ messages in thread

That was my first thought, but unfortunately I am afraid there will be point at which I will easily make a bisection mistake, as the responsiveness of the system varies over time, so it's not really a 100% objective measure. -- Jiri Kosina SUSE Labs ^ permalink raw reply [flat|nested] 39+ messages in thread

All right. There have been only three significant changes to uhci-hcd since last summer, and two of them appear to be completely unrelated to this issue. The three commits are 3171fcabb169 USB: uhci: beautify source code 13996ca7afd5 USB: uhci: check buffer length to avoid memory overflow 0f815a0a700b USB: UHCI: fix IRQ race during initialization Reverting the first two almost certainly will not have any effect, but you may as well try it anyway. The third commit may be relevant. If you revert all three and still see the problem then it must be caused by changes outside of the USB stack. Differences in interrupt routing could be a result of changes to PCI or ACPI. Have you compared the current /proc/interrupts with versions from earlier kernels without this problem? Is occurrence of the "nobody cared" connected with any particular device? Somebody reported a similar problem not long ago (although IIRC it was for OHCI rather than UHCI) which appeared to be related to activity on the built-in webcam.

It looks like the order of probing changed. The old kernel did ehci-hcd before uhci-hcd and the new kernel did them in the opposite order. Consequently usb3-usb8 in the old kernel (the UHCI devices) are the same as usb1-usb6 in the new kernel. Likewise, usb1-usb2 in the old kernel are usb7-usb8 in the new kernel. In fact, the only major difference appears to be i801_smbus on IRQ 23.

One other thing you could try: Transplant the entire uhci-hcd driver from 3.1 (or whatever) into 3.9-rc1. It should go okay -- you may have to apply by hand the appropriate parts of commits bc677d5b6464, 90ab5ee94171, and 9ffc93f203c1. Alan Stern ^ permalink raw reply [flat|nested] 39+ messages in thread

There's one other commit I failed to find at first: 840008bb5162 (USB: UHCI: notify usbcore about port resumes). Probably not relevant, but you should check to make sure.

When I had this happen on -next, it was PCI + ACPI-related and I had to bisect it. But for me the problem was quite noticable and showed up right at login prompt.

No, I didn't. I'm afraid, though, that the fix might not be effective on some systems for a reason that's unclear at the moment. So in fact the one to check is commit 4f535093cf ("PCI: Put pci_dev in device tree as early as possible") and if the problem doesn't appear before that, we need to figure out why the fix may not be sufficient.

I agree. Commit 4f535093cf ("PCI: Put pci_dev in device tree as early as possible") is the likely culprit, and "Don't cache _PRT..." is probably an insufficient fix.

With either 4f535093cf or 181380b702 I do *not* see the problem, i.e. these commits are not the culprit and it was caused by some later change.

Look at the irq 16 line: $ cat intel-interrupts.txt CPU0 CPU1 0: 23658 22859 IO-APIC-edge timer 1: 168 177 IO-APIC-edge i8042 8: 1 0 IO-APIC-edge rtc0 9: 329 347 IO-APIC-fasteoi acpi 12: 3065 3166 IO-APIC-edge i8042 16: 49732 50269 IO-APIC-fasteoi yenta, uhci_hcd:usb6 17: 1 0 IO-APIC-fasteoi firewire_ohci, uhci_hcd:usb7 18: 0 0 IO-APIC-fasteoi mmc0, uhci_hcd:usb8 19: 216 204 IO-APIC-fasteoi ehci_hcd:usb2 20: 0 0 IO-APIC-fasteoi uhci_hcd:usb3 21: 114 103 IO-APIC-fasteoi uhci_hcd:usb4 22: 0 0 IO-APIC-fasteoi uhci_hcd:usb5 23: 9 9 IO-APIC-fasteoi i801_smbus, ehci_hcd:usb1 40: 0 0 DMAR_MSI-edge dmar2 41: 0 0 DMAR_MSI-edge dmar0 42: 0 0 DMAR_MSI-edge dmar3 43: 0 0 PCI-MSI-edge PCIe PME 44: 0 0 PCI-MSI-edge PCIe PME 45: 0 0 PCI-MSI-edge PCIe PME 46: 0 0 PCI-MSI-edge PCIe PME 47: 10023 10173 PCI-MSI-edge ahci 48: 10 8 PCI-MSI-edge mei 49: 22 30 PCI-MSI-edge eth0 50: 66 71 PCI-MSI-edge i915 51: 2508 2348 PCI-MSI-edge iwlwifi 52: 168 169 PCI-MSI-edge snd_hda_intel NMI: 17 17 Non-maskable interrupts LOC: 27988 25243 Local timer interrupts SPU: 0 0 Spurious interrupts PMI: 17 17 Performance monitoring interrupts IWI: 0 0 IRQ work interrupts RTR: 0 0 APIC ICR read retries RES: 4584 2746 Rescheduling interrupts CAL: 6178 7492 Function call interrupts TLB: 702 651 TLB shootdowns TRM: 0 0 Thermal event interrupts THR: 0 0 Threshold APIC interrupts MCE: 0 0 Machine check exceptions MCP: 1 1 Machine check polls ERR: 0 MIS: 0 $ cat ati-interrupts.txt CPU0 CPU1 0: 15488 15268 IO-APIC-edge timer 1: 182 189 IO-APIC-edge i8042 8: 1 0 IO-APIC-edge rtc0 9: 328 339 IO-APIC-fasteoi acpi 12: 2071 1997 IO-APIC-edge i8042 16: 55 47 IO-APIC-fasteoi yenta, uhci_hcd:usb4 17: 1 1 IO-APIC-fasteoi firewire_ohci, uhci_hcd:usb5 18: 0 0 IO-APIC-fasteoi uhci_hcd:usb6, mmc0 19: 219 202 IO-APIC-fasteoi ehci_hcd:usb8 20: 0 0 IO-APIC-fasteoi uhci_hcd:usb1 21: 112 104 IO-APIC-fasteoi uhci_hcd:usb2 22: 0 0 IO-APIC-fasteoi uhci_hcd:usb3 23: 10 8 IO-APIC-fasteoi i801_smbus, ehci_hcd:usb7 40: 0 0 DMAR_MSI-edge dmar1 41: 0 0 DMAR_MSI-edge dmar0 42: 0 0 DMAR_MSI-edge dmar2 43: 0 0 PCI-MSI-edge PCIe PME 44: 0 0 PCI-MSI-edge PCIe PME 45: 0 0 PCI-MSI-edge PCIe PME 46: 0 0 PCI-MSI-edge PCIe PME 47: 0 0 PCI-MSI-edge PCIe PME 48: 9733 9932 PCI-MSI-edge ahci 49: 9 9 PCI-MSI-edge mei 50: 2308 2196 PCI-MSI-edge iwlwifi 51: 15 35 PCI-MSI-edge eth0 52: 818 815 PCI-MSI-edge radeon 53: 167 167 PCI-MSI-edge snd_hda_intel NMI: 17 16 Non-maskable interrupts LOC: 18139 34223 Local timer interrupts SPU: 0 0 Spurious interrupts PMI: 17 16 Performance monitoring interrupts IWI: 0 0 IRQ work interrupts RTR: 0 0 APIC ICR read retries RES: 3788 3563 Rescheduling interrupts CAL: 6303 5894 Function call interrupts TLB: 711 711 TLB shootdowns TRM: 0 0 Thermal event interrupts THR: 0 0 Threshold APIC interrupts MCE: 0 0 Machine check exceptions MCP: 1 1 Machine check polls ERR: 0 MIS: 0 -- Hilsen Harald ^ permalink raw reply [flat|nested] 39+ messages in thread

Just a datapoint -- I have put a trivial debugging patch in place, and it reveals that "nobody cared" for irq 16 happens long after last I915_WRITE(GMBUS4 + reg_offset, 0); has been performed in gmbus_wait_hw_status(). On the other hand, if I comment out both GMBUS4 register offset writes in gmbus_wait_hw_status(), then it of course falls back to GPIO bit-banging, but the "nobody cared" for irq 16 is gone. So it seems like something gets severely confused by the I915_WRITE to GMBUS4 + reg_offset. So far this seems to have been reported solely on Lenovos as far as I can see (although a completely different types), so it might be some platform-specific quirk? Honestly, I still don't understand how all the GMBUS stuff relates to IRQ 16 at all. -- Jiri Kosina SUSE Labs ^ permalink raw reply [flat|nested] 39+ messages in thread

Yes, switching from MSI to IO-APIC-fasteoi makes the report about lost interrupts go away. My understanding from the other mail is that DAniel Vetter already has an idea what might be going wrong with IRQ acking on GM45 chipsets; hopefully this datapoint regarding MSI will fit into it. -- Jiri Kosina SUSE Labs ^ permalink raw reply [flat|nested] 39+ messages in thread

Yep, there's a big comment in the irq handler for that chipset that we have a gaping race with when using MSI interrupts. Although the comment bodly claims that the race is small enough to avoid the dreaded "nobody cared" message. Looks like gmbus is good at hitting that race - on newer chips it already brought up a similar race in handling pch interrupts. Can you please give the below patch a whirl? It removes the probably race msi race avoidance code and replaces it with the same trick Paulo used to fix pch irq handling races.

It turns out though that on many systems this leads to spurious interrupts being generated, long after the register write to disable the IRQs has been issued. Flushing of the register writes by POSTING_READ() directly after the register write doesn't work either. Disable using of GMBUS IRQs on Gen4 systems before the root cause is found and revert back to old behavior. Also be more careful about not issuing GMBUS4 register reads in gmbus_wait_hw_status() if we are not using GMBUS IRQs.

I explicitly wanted to avoid touching GMBUS4 register, as the real cause of the failure is not clear. But, as Yinghai Lu points out, the problem is most likely caused by interrupt disabling not working properly (see his very good point regarding DisINTx+ and INTx+ discrepancy), so zeroing the register out should work .... and it indeed does in my case, hence the (tested) patch below. I think it's a 3.9-rc material, and I am all open to debug this further for 3.10 so that the race is closed and gmbus irqs can be used on Gen4 platform properly.

Agreed. Using the IRQ for GMBUS is just a performance feature that can be deferred until after we determine the root cause - and hope that the failure is somehow peculiar to GMBUS.

I'd prefer if we dig into this for a bit more. I've been traveling last week and only just now recovered from the mail backlog, hence my delays in handling this. Also the "nobody cared" showing up only very late after the last gmbus transaction isn't too surprising: It only fires after 100k interrupts, and apparently the irq handler is already a bit racy, so any interrupt might push it over the edge. gmbus interrupts are apparently just help to expose the race (presuming it's indeed the msi race already docuemented in the code). -Daniel > From: Jiri Kosina <jkosina@suse.cz> > Subject: [PATCH] drm/i915: stop using GMBUS IRQs on Gen4 chips > > Commit 28c70f162 ("drm/i915: use the gmbus irq for waits") switched to > using GMBUS irqs instead of GPIO bit-banging for chipset generations 4 > and above. > > It turns out though that on many systems this leads to spurious interrupts > being generated, long after the register write to disable the IRQs has been > issued. > > Flushing of the register writes by POSTING_READ() directly after the register > write doesn't work either. > > Disable using of GMBUS IRQs on Gen4 systems before the root cause is found and > revert back to old behavior. > > Also be more careful about not issuing GMBUS4 register reads in > gmbus_wait_hw_status() if we are not using GMBUS IRQs. > > Signed-off-by: Jiri Kosina <jkosina@suse.cz> > --- > drivers/gpu/drm/i915/intel_i2c.c | 12 ++++++++++-- > 1 files changed, 10 insertions(+), 2 deletions(-) > > diff --git a/drivers/gpu/drm/i915/intel_i2c.c b/drivers/gpu/drm/i915/intel_i2c.c > index acf8aec..8638036 100644 > --- a/drivers/gpu/drm/i915/intel_i2c.c > +++ b/drivers/gpu/drm/i915/intel_i2c.c > @@ -58,12 +58,14 @@ to_intel_gmbus(struct i2c_adapter *i2c) > return container_of(i2c, struct intel_gmbus, adapter); > } > > +#define HAS_GMBUS_IRQ(dev) (INTEL_INFO(dev)->gen >= 5) > void > intel_i2c_reset(struct drm_device *dev) > { > struct drm_i915_private *dev_priv = dev->dev_private; > I915_WRITE(dev_priv->gpio_mmio_base + GMBUS0, 0); > - I915_WRITE(dev_priv->gpio_mmio_base + GMBUS4, 0); > + if (HAS_GMBUS_IRQ(dev)) > + I915_WRITE(dev_priv->gpio_mmio_base + GMBUS4, 0); > } > > static void intel_i2c_quirk_set(struct drm_i915_private *dev_priv, bool enable) > @@ -203,7 +205,6 @@ intel_gpio_setup(struct intel_gmbus *bus, u32 pin) > algo->data = bus; > } > > -#define HAS_GMBUS_IRQ(dev) (INTEL_INFO(dev)->gen >= 4) > static int > gmbus_wait_hw_status(struct drm_i915_private *dev_priv, > u32 gmbus2_status, > @@ -214,6 +215,13 @@ gmbus_wait_hw_status(struct drm_i915_private *dev_priv, > u32 gmbus2 = 0; > DEFINE_WAIT(wait); > > + if (!HAS_GMBUS_IRQ(dev_priv->dev)) { > + int ret; > + ret = wait_for((gmbus2 = I915_READ(GMBUS2 + reg_offset)) & > + (GMBUS_SATOER | gmbus2_status), > + 50); > + return ret; > + } > /* Important: The hw handles only the first bit, so set only one!
