2014-11-25Merge branch 'ipv6_vxlan_outer_udp_csum'David S. Miller2-5/+3
Alexander Duyck says: ==================== Fix outer UDP checksums for IPv6 VXLAN tunnels In testing against an older kernel I found a couple issues in the IPv6 VXLAN tunnel checksum logic for the outer UDP checksum. First the default transitioned from using an outer checksum to not using one. Second, sometime after that the checksum inputs were changed resulting the checksum not being correct if it were computed. These two issues prevented a ping from the newer kernel to the older one. With these two changes applied I verified I was able to send traffic over the VXLAN tunnel to a link partner on an older kernel. The boolean flip fix can be submitted for 3.17 stable as well since the patch that introduced the issue was included in that kernel. ==================== Signed-off-by: David S.

2014-11-24drm/i915: Ignore SURFLIVE and flip counter when the GPU gets resetVille Syrjälä1-0/+4
During a GPU reset we need to get pending page flip cleared out since the ring contents are gone and flip will never complete on its own. This used to work until the mmio vs. CS flip race detection came about. That piece of code is looking for a specific surface address in the SURFLIVE register, but as a flip to that address may never happen the check may never pass. So we should just skip the SURFLIVE and flip counter checks when the GPU gets reset. intel_display_handle_reset() tries to effectively complete the flip anyway by calling .update_primary_plane(). But that may not satisfy the conditions of the mmio vs. CS race detection since there's no guarantee that a modeset didn't sneak in between the GPU reset and intel_display_handle_reset(). Such a modeset will not wait for pending flips due to the ongoing GPU reset, and then the primary plane updates performed by intel_display_handle_reset() will already use the new surface address, and thus the surface address the flip is waiting for might never appear in SURFLIVE. The result is that the flip will never complete and attempts to perform further page flips will fail with -EBUSY. During the GPU reset intel_crtc_has_pending_flip() will return false regardless, so the deadlock with a modeset vs. the error work acquiring crtc->mutex was avoided. And the reset_counter check in intel_crtc_has_pending_flip() actually made this bug even less severe since it allowed normal modesets to go through even though there's a pending flip. This is a regression introduced by me here: commit 75f7f3ec600524c9544cc31695155f1a9ddbe1d9 Author: Ville Syrjälä <[email protected]> Date: Tue Apr 15 21:41:34 2014 +0300 drm/i915: Fix mmio vs. CS flip race on ILK+ Testcase: igt/kms_flip/flip-vs-panning-vs-hang Signed-off-by: Ville Syrjälä <[email protected]> Reviewed-by: Chris Wilson <[email protected]> Reviewed-by: Daniel Vetter <[email protected]> Cc: [email protected] Signed-off-by: Jani Nikula <[email protected]>

2014-11-24powerpc/pci: Remove unused force_32bit_msi quirkBenjamin Herrenschmidt2-12/+0
This is now fully replaced with the generic "no_64bit_msi" one that is set by the respective drivers directly. Signed-off-by: Benjamin Herrenschmidt <[email protected]>

2014-11-24sound/radeon: Move 64-bit MSI quirk from arch to driverBenjamin Herrenschmidt2-2/+9
A number of radeon cards have a HW limitation causing them to be unable to generate the full 64-bit of address bits for MSIs. This breaks MSIs on some platforms such as POWER machines. We used to have a powerpc specific quirk to address that on a single card, but this doesn't scale very well, this is better put under control of the drivers who know precisely what a given HW revision can do. We now have a generic quirk in the PCI code. We should set it appropriately for all radeon's from the audio driver.

2014-11-24gpu/radeon: Set flag to indicate broken 64-bit MSIBenjamin Herrenschmidt1-0/+10
Some radeon ASICs don't support all 64 address bits of MSIs despite advertising support for 64-bit MSIs in their configuration space. This breaks on systems such as IBM POWER7/8, where 64-bit MSIs can be assigned with some of the high address bits set. This makes use of the newly introduced "no_64bit_msi" flag in structure pci_dev to allow the MSI allocation code to fallback to 32-bit MSIs on those adapters.

Patch to the driver is identical to the reviewed one, I dropped the arch/powerpc hunk rewrote the subject and cset comment.
2014-11-24PCI/MSI: Add device flag indicating that 64-bit MSIs don't workBenjamin Herrenschmidt2-0/+27
This can be set by quirks/drivers to be used by the architecture code that assigns the MSI addresses. We additionally add verification in the core MSI code that the values assigned by the architecture do satisfy the limitation in order to fail gracefully if they don't (ie. the arch hasn't been updated to deal with that quirk yet).

2014-11-24ALSA: hda - Limit 40bit DMA for AMD HDMI controllersTakashi Iwai1-3/+11
AMD/ATI HDMI controller chip models, we already have a filter to lower to 32bit DMA, but the rest are supposed to be working with 64bit although the hardware doesn't really work with 63bit but only with 40 or 48bit DMA. In this patch, we take 40bit DMA for safety for the AMD/ATI controllers as the graphics drivers does.

2014-11-23uprobes, x86: Fix _TIF_UPROBE vs _TIF_NOTIFY_RESUMEAndy Lutomirski2-2/+1
x86 call do_notify_resume on paranoid returns if TIF_UPROBE is set but not on non-paranoid returns. I suspect that this is a mistake and that the code only works because int3 is paranoid. Setting _TIF_NOTIFY_RESUME in the uprobe code was probably a workaround for the x86 bug. With that bug fixed, we can remove _TIF_NOTIFY_RESUME from the uprobes code.
