2022-05-11genirq: Remove WARN_ON_ONCE() in generic_handle_domain_irq()Lukas Wunner1-1/+0
Since commit 0953fb263714 ("irq: remove handle_domain_{irq,nmi}()"), generic_handle_domain_irq() warns if called outside hardirq context, even though the function calls down to handle_irq_desc(), which warns about the same, but conditionally on handle_enforce_irqctx(). The newly added warning is a false positive if the interrupt originates from any other irqchip than x86 APIC or ARM GIC/GICv3. Those are the only ones for which handle_enforce_irqctx() returns true. Per commit c16816acd086 ("genirq: Add protection against unsafe usage of generic_handle_irq()"): "In general calling generic_handle_irq() with interrupts disabled from non interrupt context is harmless. For some interrupt controllers like the x86 trainwrecks this is outright dangerous as it might corrupt state if an interrupt affinity change is pending." Examples for interrupt chips where the warning is a false positive are USB-attached GPIO controllers such as drivers/gpio/gpio-dln2.c: USB gadgets are incapable of directly signaling an interrupt because they cannot initiate a bus transaction by themselves. All communication on the bus is initiated by the host controller, which polls a gadget's Interrupt Endpoint in regular intervals. If an interrupt is pending, that information is passed up the stack in softirq context, from which a hardirq is synthesized via generic_handle_domain_irq(). Remove the warning to eliminate such false positives.

2022-05-10Merge branch 'move-siena-into-a-separate-subdirectory'Jakub Kicinski48-122/+24114
Martin Habets says: ==================== Move Siena into a separate subdirectory The Siena NICs (SFN5000 and SFN6000 series) went EOL in November 2021. Most of these adapters have been remove from our test labs, and testing has been reduced to a minimum. This patch series creates a separate kernel module for the Siena architecture, analogous to what was done for Falcon some years ago. This reduces our maintenance for the sfc.ko module, and allows us to enhance the EF10 and EF100 drivers without the risk of breaking Siena NICs. After this series further enhancements are needed to differentiate the new kernel module from sfc.ko, and the Siena code can be removed from sfc.ko. Thes will be posted as a small follow-up series. The Siena module is not built by default, but can be enabled using Kconfig option SFC_SIENA. This will create module sfc-siena.ko. Patches Patches 1-3 establish the code base for the Siena driver. Patches 4-10 ensure the allyesconfig build succeeds. Patch 11 adds the basic Siena module. I do not expect patch 1 through 3 to be reviewed, they are FYI only. No checkpatch issues were resolved as part of these, but they were fixed in the subsequent patches. Testing Various build tests were done such as allyesconfig, W=1 and sparse. The new sfc-siena.ko and sfc.ko modules were tested on a machine with both these NICs in them, and several tests were run on both drivers. ==================== Link: https://lore.kernel.org/r/165211018297.5289.9658523545298485394.stgit@palantir17.mph.net Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2022-05-10drm/amd/display: do not calculate DP2.0 SST payload when link is offWenjing Liu1-1/+2
[Why & How] There is a chance where the RX issues HPD deassert in the middle of link training, this will cause our logic to abort link training and turn off link. However our payload allocation logic needs to use current link settings to determine average time slot per MTP. This will need to use current link bandwidth as divider. This causes divide by zero error occasionally. The fix is to skip DP2.0 payload allocation logic if current link is not in 128b/132b mode.
