2020-07-14Merge branch 'bridge-mrp-Add-support-for-interconnect-ring'David S. Miller
Horatiu Vultur says: ==================== bridge: mrp: Add support for interconnect ring This patch series extends existing MRP to add support for interconnect ring. An interconnect ring is a ring that connects 2 rings. In this way is possible to connect multiple rings. Each interconnect ring is form of 4 nodes, in which 3 have the role MIC(Media Redundancy Interconnect Client) and one has the role MIM(Media Redundancy Interconnect Manager). All these nodes need to have the same ID and the ID needs to be unique between multiple interconnect rings. And 2 nodes needs to be part of one ring and the other 2 nodes needs to be part of the other ring that is connected. +---------+ | | +----------| MRM |---------------+ | | | | | +---------+ | | | | | | | +--------------+ +-----------------+ | | | | | MRC/MIC |------------------| MRC/MIM | | | | | +--------------+ +-----------------+ | | |Interconnect port |Interconnect port | | | | +--------------+ +-----------------+ | | | | | MRC/MIC |----------------- | MRC/MIC | | | | | +--------------+ +-----------------+ | | | | | +---------+ | | | | | +----------| MRM |----------------+ | | +---------+ Each node in a ring needs to have one of the following ring roles, MRM or MRC. And it can also have an interconnect role like MIM or MIC if it is part of an interconnect ring. In the figure above the MRM doesn't have any interconnect role but the MRC from the top ring have the interconnect roles MIC respectively MIM. Therefore it is not possible for a node to have only an interconnect role. There are 2 ways for interconnect ring to detect when is open or closed: 1. To use CCM frames on the interconnect port to detect when the interconnect link goes down/up. This mode is called LC-mode. 2. To send InTest frames on all 3 ports(2 ring ports and 1 interconnect port) and detect when these frames are received back. This mode is called RC-mode. This patch series adds support only for RC-mode. Where MIM sends InTest frames on all 3 ports and detects when it receives back the InTest. When it receives the InTest it means that the ring is closed so it would set the interconnect port in blocking state. If it stops receiving the InTest frames then it would set the port in forwarding state and it would send InTopo frames. These InTopo frames will be received by MRM nodes and process them. And then the MRM will send Topo frames in the rings so each client will clear its FDB. v4: - always cancel delay work if the MRP instance is deleted or interconnect role is disabled but allow only to start to send InTest frames only if the role is MIM. v3: - update 'br_mrp_set_in_role' to stop sending test if the role is disabled and don't allow to set a different interconnect port if there is already one. v2: - rearrange structures not to contain holes - stop sending MRP_InTest frames when the MRP instance is deleted ==================== Signed-off-by: David S.

2020-07-14bpfilter: Allow to build bpfilter_umh as a module without static libraryMasahiro Yamada
Originally, bpfilter_umh was linked with -static only when CONFIG_BPFILTER_UMH=y. Commit 8a2cc0505cc4 ("bpfilter: use 'userprogs' syntax to build bpfilter_umh") silently, accidentally dropped the CONFIG_BPFILTER_UMH=y test in the Makefile. Revive it in order to link it dynamically when CONFIG_BPFILTER_UMH=m. Since commit b1183b6dca3e ("bpfilter: check if $(CC) can link static libc in Kconfig"), the compiler must be capable of static linking to enable CONFIG_BPFILTER_UMH, but it requires more than needed. To loosen the compiler requirement, I changed the dependency as follows: depends on CC_CAN_LINK depends on m || CC_CAN_LINK_STATIC If CONFIG_CC_CAN_LINK_STATIC in unset, CONFIG_BPFILTER_UMH is restricted to 'm' or 'n'. In theory, CONFIG_CC_CAN_LINK is not required for CONFIG_BPFILTER_UMH=y, but I did not come up with a good way to describe it.

2020-07-14drm/i915: Recalculate FBC w/a stride when neededVille Syrjälä
Currently we're failing to recalculate the gen9 FBC w/a stride unless something more drastic than just the modifier itself has changed. This often leaves us with FBC enabled with the linear fbdev framebuffer without the w/a stride enabled. That will cause an immediate underrun and FBC will get promptly disabled. Fix the problem by checking if the w/a stride is about to change, and go through the full dance if so. This part of the FBC code is still pretty much a disaster and will need lots more work. But this should at least fix the immediate issue. v2: Deactivate FBC when the modifier changes since that will likely require resetting the w/a CFB stride Cc: stable@vger.kernel.org Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200711080336.13423-1-ville.syrjala@linux.intel.com Reviewed-by: José Roberto de Souza <jose.souza@intel.com> (cherry picked from commit 0428ab013fdd39dbfb8f4cd8ad2b60af3776c6b9) Signed-off-by: Jani Nikula <jani.nikula@intel.com>

2020-07-14drm/i915/gt: Ignore irq enabling on the virtual enginesChris Wilson
We do not use the virtual engines for interrupts (they have physical components), but we do use them to decouple the fence signaling during submission. Currently, when we submit a completed request, we try to enable the interrupt handler for the virtual engine, but we never disarm it. A quick fix is then to mark the irq as enabled, and it will then remain enabled -- and this prevents us from waking the device and never letting it sleep again.

2020-07-14irqdomain/treewide: Keep firmware node unconditionally allocatedThomas Gleixner
Quite some non OF/ACPI users of irqdomains allocate firmware nodes of type IRQCHIP_FWNODE_NAMED or IRQCHIP_FWNODE_NAMED_ID and free them right after creating the irqdomain. The only purpose of these FW nodes is to convey name information. When this was introduced the core code did not store the pointer to the node in the irqdomain. A recent change stored the firmware node pointer in irqdomain for other reasons and missed to notice that the usage sites which do the alloc_fwnode/create_domain/free_fwnode sequence are broken by this. Storing a dangling pointer is dangerous itself, but in case that the domain is destroyed later on this leads to a double free. Remove the freeing of the firmware node after creating the irqdomain from all affected call sites to cure this.
