2020-07-29mlxsw: spectrum: Use different trap group for externally routed packetsIdo Schimmel1-0/+4
Cited commit mistakenly removed the trap group for externally routed packets (e.g., via the management interface) and grouped locally routed and externally routed packet traps under the same group, thereby subjecting them to the same policer. This can result in problems, for example, when FRR is restarted and suddenly all transient traffic is trapped to the CPU because of a default route through the management interface. Locally routed packets required to re-establish a BGP connection will never reach the CPU and the routing tables will not be re-populated. Fix this by using a different trap group for externally routed packets.

git://people.freedesktop.org/~gabbayo/linux into char-misc-linus This tag contains the following fixes for 5.8-rc4/5: - Prevent user from using command WREG_BULK in PCI DMA channel. The command won't be parsed correctly by the driver and will cause unknown behavior. As the user doesn't need to use that command in that channel, its better to just prevent it completely. - Change the interface of the clock gating debugfs property from true/false to bitmask with bit per engine. This will allow the user to debug the ASIC while disabling the clock gating feature with fine-grain granularity. - Increase message-to-ASIC-CPU timeout to 4s (from 100ms/1s). The ASIC CPU might respond sometimes after a large delay due to slow external interfaces (such as temperature sensors) and that will result in a driver timeout which will lead to ASIC reset. * tag 'misc-habanalabs-fixes-2020-07-10' of git://people.freedesktop.org/~gabbayo/linux: habanalabs: set 4s timeout for message to device CPU habanalabs: set clock gating per engine habanalabs: block WREG_BULK packet on PDMA

Now that the IOMMU driver has been introduced, it prevents any access from a DMA master going through it that hasn't properly mapped the pages, and that link is set up through the iommus property.

P9 DD2 NX workbook (Table 4-36) says DMA controller uses CC=5 internally for translation fault handling. NX reserves CC=250 for OS to notify user space when NX encounters address translation failure on the request buffer. Not an issue in earlier releases as NX does not get faults on kernel addresses. This patch defines CSB_CC_FAULT_ADDRESS(250) and updates CSB.CC with this proper error code for user space.
