2017-08-15xen: fix bio vec mergingRoger Pau Monne1-2/+1
The current test for bio vec merging is not fully accurate and can be tricked into merging bios when certain grant combinations are used. The result of these malicious bio merges is a bio that extends past the memory page used by any of the originating bios. Take into account the following scenario, where a guest creates two grant references that point to the same mfn, ie: grant 1 -> mfn A, grant 2 -> mfn A. These references are then used in a PV block request, and mapped by the backend domain, thus obtaining two different pfns that point to the same mfn, pfn B -> mfn A, pfn C -> mfn A. If those grants happen to be used in two consecutive sectors of a disk IO operation becoming two different bios in the backend domain, the checks in xen_biovec_phys_mergeable will succeed, because bfn1 == bfn2 (they both point to the same mfn). However due to the bio merging, the backend domain will end up with a bio that expands past mfn A into mfn A + 1. Fix this by making sure the check in xen_biovec_phys_mergeable takes into account the offset and the length of the bio, this basically replicates whats done in __BIOVEC_PHYS_MERGEABLE using mfns (bus addresses). While there also remove the usage of __BIOVEC_PHYS_MERGEABLE, since that's already checked by the callers of xen_biovec_phys_mergeable. CC: stable@vger.kernel.org Reported-by: "Jan H.

2017-08-14PCI: Disable Relaxed Ordering for some Intel processorsdingtianhong1-0/+62
According to the Intel spec section 3.9.1 said: 3.9.1 Optimizing PCIe Performance for Accesses Toward Coherent Memory and Toward MMIO Regions (P2P) In order to maximize performance for PCIe devices in the processors listed in Table 3-6 below, the soft- ware should determine whether the accesses are toward coherent memory (system memory) or toward MMIO regions (P2P access to other devices). If the access is toward MMIO region, then software can command HW to set the RO bit in the TLP header, as this would allow hardware to achieve maximum throughput for these types of accesses. For accesses toward coherent memory, software can command HW to clear the RO bit in the TLP header (no RO), as this would allow hardware to achieve maximum throughput for these types of accesses.

2017-08-14PCI: Disable PCIe Relaxed Ordering if unsupporteddingtianhong2-0/+54
When bit4 is set in the PCIe Device Control register, it indicates whether the device is permitted to use relaxed ordering. On some platforms using relaxed ordering can have performance issues or due to erratum can cause data-corruption. In such cases devices must avoid using relaxed ordering. The patch adds a new flag PCI_DEV_FLAGS_NO_RELAXED_ORDERING to indicate that Relaxed Ordering (RO) attribute should not be used for Transaction Layer Packets (TLP) targeted towards these affected root complexes. This patch checks if there is any node in the hierarchy that indicates that using relaxed ordering is not safe. In such cases the patch turns off the relaxed ordering by clearing the capability for this device.

2017-08-14drm/i915: Avoid the gpu reset vs. modeset deadlockDaniel Vetter1-0/+7
... using the biggest hammer we have. This is essentially a weaponized version of the timeout-based wedging Chris added in commit 36703e79a982c8ce5a8e43833291f2719e92d0d1 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Thu Jun 22 11:56:25 2017 +0100 drm/i915: Break modeset deadlocks on reset Because defense-in-depth is good it's good to still have both. Also note that with the locking change we can now restrict this a lot (old gpus and special testing only), so this doesn't kill the TDR benefits on at least anything remotely modern. And futuremore with a few tricks it should be possible to make a much more educated guess about whether an atomic commit is stuck waiting on the gpu (atomic_t counting the pending i915_sw_fence used by the atomic modeset code should do it), so we can improve this. But for now just start with something that is guaranteed to recover faster, for much better CI througput. This defacto reverts TDR on these platforms, but there's not really a single commit to specify as the sole offender. v2: Add a debug message to explain what's going on. We can't DRM_ERROR because that spams CI. And the timeout based fallback still prints a DRM_ERROR, in case something goes wrong. v3: Fix comment layout (Michel) Fixes: 4680816be336 ("drm/i915: Wait first for submission, before waiting for request completion") Fixes: 221fe7994554 ("drm/i915: Perform a direct reset of the GPU from the waiter") Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Mika Kuoppala <mika.kuoppala@intel.com> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> (v2) Cc: Michel Thierry <michel.thierry@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> (v2) Reviewed-by: Michel Thierry <michel.thierry@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20170808080828.23650-1-daniel.vetter@ffwll.ch (cherry picked from commit 97154ec242c14f646a3ab3b4da8f838d197f300d) Signed-off-by: Jani Nikula <jani.nikula@intel.com>
2017-08-14drm/i915: Suppress switch_mm emission between the same aliasing_ppgttChris Wilson1-7/+8
When switching between contexts using the aliasing_ppgtt, the VM is shared. We don't need to reload the PD registers unless they are dirty. Martin Peres reported an issue that looks like corruption between Haswell context switches, bisecting to commit f9326be5f1d3 ("drm/i915: Rearrange switch_context to load the aliasing ppgtt on first use"). Switching between the same mm (the aliasing_ppgtt is used for all contexts in this case) should be a nop, but appears to trigger some side-effects in the context switch. However, as we know the switch is redundant in this case, we can skip it and continue to ignore the issue until somebody feels strong enough to investigate full-ppgtt on gen7 again! Except.. Martin was using full-ppgtt which is not supported as it doesn't work correctly yet. So whilst the bisect did yield valuable information about the failures, the fix should not have any user impact under default settings, with the exception of a slightly lower throughput on xcs as the VM would always be reloaded. v2: Also remember to set the legacy_active_context following the switch on xcs (commit e8a9c58fcd9a ("drm/i915: Unify active context tracking between legacy/execlists/guc")) Fixes: f9326be5f1d3 ("drm/i915: Rearrange switch_context to load the aliasing ppgtt on first use") Fixes: e8a9c58fcd9a ("drm/i915: Unify active context tracking between legacy/execlists/guc") Reported-by: Martin Peres <martin.peres@linux.intel.com> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Martin Peres <martin.peres@linux.intel.com> Reviewed-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20170812152724.6883-1-chris@chris-wilson.co.uk (cherry picked from commit 12124bea5b82dc1e917304aed703c27292270051) Signed-off-by: Jani Nikula <jani.nikula@intel.com>

2017-08-14drm/i915: Perform an invalidate prior to executing golden renderstateChris Wilson1-0/+4
As we may have just bound the renderstate into the GGTT for execution, we need to ensure that the GTT TLB are also flushed. On snb-gt2, this would cause a random GPU hang at the start of a new context (e.g. boot) and on snb-gt1, it was causing the renderstate batch to take ~10s. It was the GPU hang that revealed the truth, as the CS gleefully executed beyond the end of the golden renderstate batch, a good indicator for a GTT TLB miss.

2017-08-14gpio: reject invalid gpio before getting gpio_descMasami Hiramatsu1-2/+8
Check user-given gpio number and reject it before calling gpio_to_desc() because gpio_to_desc() is for kernel driver and it expects given gpio number is valid (means 0 to 511). If given number is invalid, gpio_to_desc() calls WARN() and dump registers and stack for debug. This means user can easily kick WARN() just by writing invalid gpio number (e.g. 512) to /sys/class/gpio/export.

2017-08-13bonding: ratelimit failed speed/duplex update warningAndreas Born1-3/+4
bond_miimon_commit() handles the UP transition for each slave of a bond in the case of MII. It is triggered 10 times per second for the default MII Polling interval of 100ms. For device drivers that do not implement __ethtool_get_link_ksettings() the call to bond_update_speed_duplex() fails persistently while the MII status could remain UP. That is, in this and other cases where the speed/duplex update keeps failing over a longer period of time while the MII state is UP, a warning is printed every MII polling interval. To address these excessive warnings net_ratelimit() should be used. Printing a warning once would not be sufficient since the call to bond_update_speed_duplex() could recover to succeed and fail again later. In that case there would be no new indication what went wrong.
