[PATCH v2] mtd: spi-nor: Check for zero erase size in spi_nor_find_best_erase_type()

by Alexander A Sverdlin

From: Alexander Sverdlin <alexander.sverdlin(a)nokia.com> Erase can be zeroed in spi_nor_parse_4bait() or spi_nor_init_non_uniform_erase_map(). In practice it happened with mt25qu256a, which supports 4K, 32K, 64K erases with 3b address commands, but only 4K and 64K erase with 4b address commands.

[PATCH] virt: acrn: obtain pa from VMA with PFNMAP flag

by Yonghua Huang

acrn_vm_ram_map can't pin the user pages with VM_PFNMAP flag by calling get_user_pages_fast(), the PA(physical pages) may be mapped by kernel driver and set PFNMAP flag. This patch fixes logic to setup EPT mapping for PFN mapped RAM region by checking the memory attribute before adding EPT mapping for them.

[PATCH AUTOSEL 5.15 01/41] spi: spi-cadence: Fix SPI CS gets toggling sporadically

by Sasha Levin

From: Sai Krishna Potthuri <lakshmi.sai.krishna.potthuri(a)xilinx.com> [ Upstream commit 21b511ddee09a78909035ec47a6a594349fe3296 ] As part of unprepare_transfer_hardware, SPI controller will be disabled which will indirectly deassert the CS line. This will create a problem in some of the devices where message will be transferred with cs_change flag set(CS should not be deasserted). As per SPI controller implementation, if SPI controller is disabled then all output enables are inactive and all pins are set to input mode which means CS will go to default state high(deassert). This leads to an issue when core explicitly ask not to deassert the CS (cs_change = 1). This patch fix the above issue by checking the Slave select status bits from configuration register before disabling the SPI.

[PATCH v5] topology: make core_mask include at least cluster_siblings

by Darren Hart

Ampere Altra defines CPU clusters in the ACPI PPTT. They share a Snoop Control Unit, but have no shared CPU-side last level cache. cpu_coregroup_mask() will return a cpumask with weight 1, while cpu_clustergroup_mask() will return a cpumask with weight 2. As a result, build_sched_domain() will BUG() once per CPU with: BUG: arch topology borken the CLS domain not a subset of the MC domain The MC level cpumask is then extended to that of the CLS child, and is later removed entirely as redundant. This sched domain topology is an improvement over previous topologies, or those built without SCHED_CLUSTER, particularly for certain latency sensitive workloads. With the current scheduler model and heuristics, this is a desirable default topology for Ampere Altra and Altra Max system. Rather than create a custom sched domains topology structure and introduce new logic in arch/arm64 to detect these systems, update the core_mask so coregroup is never a subset of clustergroup, extending it to cluster_siblings if necessary. Only do this if CONFIG_SCHED_CLUSTER is enabled to avoid also changing the topology (MC) when CONFIG_SCHED_CLUSTER is disabled. This has the added benefit over a custom topology of working for both symmetric and asymmetric topologies. It does not address systems where the CLUSTER topology is above a populated MC topology, but these are not considered today and can be addressed separately if and when they appear. The final sched domain topology for a 2 socket Ampere Altra system is unchanged with or without CONFIG_SCHED_CLUSTER, and the BUG is avoided: For CPU0: CONFIG_SCHED_CLUSTER=y CLS [0-1] DIE [0-79] NUMA [0-159] CONFIG_SCHED_CLUSTER is not set DIE [0-79] NUMA [0-159] Signed-off-by: Darren Hart <darren(a)os.amperecomputing.com> Suggested-by: Barry Song <song.bao.hua(a)hisilicon.com> Reviewed-by: Barry Song <song.bao.hua(a)hisilicon.com> Acked-by: Sudeep Holla <sudeep.holla(a)arm.com> Reviewed-by: Dietmar Eggemann <dietmar.eggemann(a)arm.com> Cc: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> Cc: "Rafael J.

Consequently when the device driver tries to access 06:08.0 according to its designated address range it pokes at an unassigned I/O location, likely subtractively decoded by the southbridge and forwarded to ISA, causing the driver to become confused and bail out: uhci_hcd 0000:06:08.0: host system error, PCI problems? uhci_hcd 0000:06:08.0: host controller process error, something bad happened! uhci_hcd 0000:06:08.0: host controller halted, very bad! uhci_hcd 0000:06:08.0: HCRESET not completed yet! uhci_hcd 0000:06:08.0: HC died; cleaning up if good luck happens or if bad luck does, an infinite flood of messages: uhci_hcd 0000:06:08.0: host system error, PCI problems? uhci_hcd 0000:06:08.0: host controller process error, something bad happened! uhci_hcd 0000:06:08.0: host system error, PCI problems? uhci_hcd 0000:06:08.0: host controller process error, something bad happened! uhci_hcd 0000:06:08.0: host system error, PCI problems? uhci_hcd 0000:06:08.0: host controller process error, something bad happened! [...] making the system virtually unusuable. This is because we have code to deal with a situation from PR #16263, where broken ACPI firmware reports the wrong address range for the host bridge's decoding window and trying to adjust to the window causes more breakage than leaving the BIOS assignments intact. This may work for a device directly on the root bus decoded by the host bridge only, but for a device behind one or more PCI-to-PCI (or CardBus) bridges those bridges' forwarding windows have been standardised and need to be respected, or leaving whatever has been there in a downstream device's BAR will have no effect as cycles for the addresses recorded there will have no chance to appear on the bus the device has been immediately attached to. Make sure then for a device behind a PCI-to-PCI bridge that any firmware assignment is within the bridge's relevant forwarding window or do not restore the assignment, fixing the system concerned as follows: pci_bus 0000:00: max bus depth: 4 pci_try_num: 5 [...] pci 0000:06:08.0: BAR 4: no space for [io size 0x0020] pci 0000:06:08.0: BAR 4: failed to assign [io 0xfce0-0xfcff] pci 0000:06:08.1: BAR 4: no space for [io size 0x0020] pci 0000:06:08.1: BAR 4: failed to assign [io 0xfce0-0xfcff] [...] pci_bus 0000:00: No. 2 try to assign unassigned res [...] pci 0000:06:08.0: BAR 4: no space for [io size 0x0020] pci 0000:06:08.0: BAR 4: failed to assign [io 0xfce0-0xfcff] pci 0000:06:08.1: BAR 4: no space for [io size 0x0020] pci 0000:06:08.1: BAR 4: failed to assign [io 0xfce0-0xfcff] [...] pci_bus 0000:00: No. 3 try to assign unassigned res [...] pci 0000:06:08.0: BAR 4: assigned [io 0x2000-0x201f] pci 0000:06:08.1: BAR 4: assigned [io 0x2020-0x203f] and making device 06:08.0 work correctly.

[PATCH v3] dmaengine: mxs: fix driver registering

by Dario Binacchi

Driver registration fails on SOC imx8mn as its supplier, the clock control module, is not ready. Since platform_driver_probe(), as reported by its description, is incompatible with deferred probing, we have to use platform_driver_register().

[PATCH] drm/i915/glk: ECS Liva Q2 needs GLK HDMI port timing quirk

by Jani Nikula

From: Diego Santa Cruz <Diego.SantaCruz(a)spinetix.com> The quirk added in upstream commit 90c3e2198777 ("drm/i915/glk: Add Quirk for GLK NUC HDMI port issues.") is also required on the ECS Liva Q2. Note: Would be nicer to figure out the extra delay required for the retimer without quirks, however don't know how to check for that.

The patch below does not apply to the 5.15-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ From 1dd498e5e26ad71e3e9130daf72cfb6a693fee03 Mon Sep 17 00:00:00 2001 From: James Morse <james.morse(a)arm.com> Date: Thu, 27 Jan 2022 12:20:52 +0000 Subject: [PATCH] KVM: arm64: Workaround Cortex-A510's single-step and PAC trap errata Cortex-A510's erratum #2077057 causes SPSR_EL2 to be corrupted when single-stepping authenticated ERET instructions. A single step is expected, but a pointer authentication trap is taken instead. The erratum causes SPSR_EL1 to be copied to SPSR_EL2, which could allow EL1 to cause a return to EL2 with a guest controlled ELR_EL2. Because the conditions require an ERET into active-not-pending state, this is only a problem for the EL2 when EL2 is stepping EL1. In this case the previous SPSR_EL2 value is preserved in struct kvm_vcpu, and can be restored.
