https://gitlab.freedesktop.org/drm/msm into drm-next A bit smaller this time around.. there are still a couple uabi additions for vulkan waiting in the wings, but I punted on them this cycle due to running low on time. (They should be easy enough to rebase, and if it is a problem for anyone I can push a next+uabi branch so that tu work can proceed.) The bigger change is refactoring dpu resource manager and moving dpu to use atomic global state. Other than that, it is mostly cleanups and fixes.

git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM DT and driver fixes from Arnd Bergmann: "For the devicetree files, there are a total of 20 patches, almost entirely for 32-bit machines: - The Allwinner/sun9i r40 SoC dtsi file contains a number of issues, both for correctness and for style that are addressed in separate patches. This causes most of the changed lines of the DT updates this time. - More Allwinner updates fixing the identification of the security system on sun8i/A33, a recent regression of the A83t ethernet, and a few board specific issues on the TBS-A711 macine. - Several bug fixes for OMAP dts files, most notably fixing the timings for the NAND flash on the Nokia N900 that regressed a while ago after the move to configuring them from DT. Some other OMAPs now set the correct dma limits on the L3 bus, and a regression fix addresses lost Ethernet on dm814x - One incorrect setting in the newly added Raspberry Pi Zero W that may cause issues with the SD card controller. - A missing property on the bcm2835 firmware node caused incorrect DMA settings. - An old bug on the oxnas platform causing spurious interrupts is finally addressed. - A regression on the Exynos Midas board broke the OLED panel power supply. - The i.MX6 phycore SoM specified the wrong voltage for the SoC, this is now set to the values from the datasheet. - Some 64-bit machines use a deprecated string to identify the PSCI firmware. There are also several small code fixes addressing mostly serious issues: - Fix the sunxi rsb bus access to no longer return incorrect data when mixing 8 and 16 bit I/O. - Fix a suspend/resume regression on the OMAP2+ lcdc from a missing quirk in the ti-sysc driver - Fix a NULL pointer access from a race in the fsl dpio driver - Fix a v5.5 regression in the exynos-chipid driver that caused an invalid error code probing the device on non-exynos platforms - Fix an out-of-bounds access in the AMD TEE driver" * tag 'arm-soc-fixes-5.6' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (24 commits) soc: samsung: chipid: Fix return value on non-Exynos platforms arm64: dts: Fix leftover entry-methods for PSCI ARM: dts: exynos: Fix regulator node aliasing on Midas-based boards ARM: dts: oxnas: Fix clear-mask property ARM: dts: bcm283x: Fix vc4's firmware bus DMA limitations ARM: dts: omap5: Add bus_dma_limit for L3 bus ARM: dts: omap4-droid4: Fix lost touchscreen interrupts ARM: dts: dra7: Add bus_dma_limit for L3 bus ARM: bcm2835-rpi-zero-w: Add missing pinctrl name ARM: dts: sun8i: a33: add the new SS compatible dt-bindings: crypto: add new compatible for A33 SS ARM: dts: sun8i: r40: Move SPI device nodes based on address order ARM: dts: sun8i: r40: Fix register base address for SPI2 and SPI3 ARM: dts: sun8i: r40: Move AHCI device node based on address order ARM: dts: imx6: phycore-som: fix arm and soc minimum voltage soc: fsl: dpio: register dpio irq handlers after dpio create tee: amdtee: out of bounds read in find_session() ARM: dts: N900: fix onenand timings bus: ti-sysc: Fix quirk flags for lcdc on am335x ARM: dts: Fix dm814x Ethernet by changing to use rgmii-id mode ...

2020-03-25zonfs: Fix handling of read-only zonesDamien Le Moal1-5/+13
The write pointer of zones in the read-only consition is defined as invalid by the SCSI ZBC and ATA ZAC specifications. It is thus not possible to determine the correct size of a read-only zone file on mount. Fix this by handling read-only zones in the same manner as offline zones by disabling all accesses to the zone (read and write) and initializing the inode size of the read-only zone to 0). For zones found to be in the read-only condition at runtime, only disable write access to the zone and keep the size of the zone file to its last updated value to allow the user to recover previously written data. Also fix zonefs documentation file to reflect this change. Signed-off-by: Damien Le Moal <damien.lemoal@wdc.com> Reviewed-by: Johannes Thumshirn <johannes.thumshirn@wdc.com>

2020-03-20KVM: SVM: document KVM_MEM_ENCRYPT_OP, let userspace detect if SEV is availablePaolo Bonzini1-0/+25
Userspace has no way to query if SEV has been disabled with the sev module parameter of kvm-amd.ko. Actually it has one, but it is a hack: do ioctl(KVM_MEM_ENCRYPT_OP, NULL) and check if it returns EFAULT. Make it a little nicer by returning zero for SEV enabled and NULL argument, and while at it document the ioctl arguments.

2020-03-17modpost: move the namespace field in Module.symvers lastJessica Yu1-2/+2
In order to preserve backwards compatability with kmod tools, we have to move the namespace field in Module.symvers last, as the depmod -e -E option looks at the first three fields in Module.symvers to check symbol versions (and it's expected they stay in the original order of crc, symbol, module). In addition, update an ancient comment above read_dump() in modpost that suggested that the export type field in Module.symvers was optional. I suspect that there were historical reasons behind that comment that are no longer accurate. We have been unconditionally printing the export type since 2.6.18 (commit bd5cbcedf44), which is over a decade ago now. Fix up read_dump() to treat each field as non-optional. I suspect the original read_dump() code treated the export field as optional in order to support pre <= 2.6.18 Module.symvers (which did not have the export type field). Note that although symbol namespaces are optional, the field will not be omitted from Module.symvers if a symbol does not have a namespace. In this case, the field will simply be empty and the next delimiter or end of line will follow.

several iterations of ->atomic_open() calling conventions ago, we used to need fput() if ->atomic_open() failed at some point after successful finish_open(). Now (since 2016) it's not needed - struct file carries enough state to make fput() work regardless of the point in struct file lifecycle and discarding it on failure exits in open() got unified. Unfortunately, I'd missed the fact that we had an instance of ->atomic_open() (cifs one) that used to need that fput(), as well as the stale comment in finish_open() demanding such late failure handling. Trivially fixed... Fixes: fe9ec8291fca "do_last(): take fput() on error after opening to out:" Cc: stable@kernel.org # v4.7+ Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2020-03-06dt-bindings: net: FMan erratum A050385Madalin Bucur1-0/+7
FMAN DMA read or writes under heavy traffic load may cause FMAN internal resource leak; thus stopping further packet processing. The FMAN internal queue can overflow when FMAN splits single read or write transactions into multiple smaller transactions such that more than 17 AXI transactions are in flight from FMAN to interconnect. When the FMAN internal queue overflows, it can stall further packet processing. The issue can occur with any one of the following three conditions: 1. FMAN AXI transaction crosses 4K address boundary (Errata A010022) 2. FMAN DMA address for an AXI transaction is not 16 byte aligned, i.e. the last 4 bits of an address are non-zero 3. Scatter Gather (SG) frames have more than one SG buffer in the SG list and any one of the buffers, except the last buffer in the SG list has data size that is not a multiple of 16 bytes, i.e., other than 16, 32, 48, 64, etc. With any one of the above three conditions present, there is likelihood of stalled FMAN packet processing, especially under stress with multiple ports injecting line-rate traffic. To avoid situations that stall FMAN packet processing, all of the above three conditions must be avoided; therefore, configure the system with the following rules: 1. Frame buffers must not span a 4KB address boundary, unless the frame start address is 256 byte aligned 2. All FMAN DMA start addresses (for example, BMAN buffer address, FD[address] + FD[offset]) are 16B aligned 3. SG table and buffer addresses are 16B aligned and the size of SG buffers are multiple of 16 bytes, except for the last SG buffer that can be of any size. Additional workaround notes: - Address alignment of 64 bytes is recommended for maximally efficient system bus transactions (although 16 byte alignment is sufficient to avoid the stall condition) - To support frame sizes that are larger than 4K bytes, there are two options: 1. Large single buffer frames that span a 4KB page boundary can be converted into SG frames to avoid transaction splits at the 4KB boundary, 2. Align the large single buffer to 256B address boundaries, ensure that the frame address plus offset is 256B aligned. - If software generated SG frames have buffers that are unaligned and with random non-multiple of 16 byte lengths, before transmitting such frames via FMAN, frames will need to be copied into a new single buffer or multiple buffer SG frame that is compliant with the three rules listed above.
