* EDAC, skx: Let EDAC core show the decoded result for debugfsQiuxu Zhuo2018-11-161-46/+48
| | | | | | | | | | | | | | | | | | | | Current debugfs shows the decoded result in its own print format which is inconvenient for analysis/statistics. Use skx_mce_check_error() instead of skx_decode() for debugfs, then the decoded result is showed via EDAC core in a more readable format like "CPU_SrcID#[0-9]_MC#[0-9]_Chan#[0-9]_DIMM#[0-9]". Print a warning the first time this interface is used so the administrator can see the console log that error(s) have been faked.

| | | | | | | | | | | | | | | | | | Some debug/error strings in hex formatting do not have the '0x' prefix. Prepend hex formatting with '0x' for them, but with one exception: "Couldn't enable %04x:%04x", instead of putting '0x' in this line, add the word 'device'.

* EDAC, skx: Fix randconfig builds in a better wayLuck, Tony2018-11-071-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | It was previously noted that Kconfig complained about unmet dependencies when trying to configure skx_edac together with CONFIG_ACPI=n. First fix for this checked for ACPI when doing select ACPI_ADXL but this required stub functions for the case where ACPI wasn't selected. It also allowed building a driver that didn't actually work for a system that has non-volatile DIMMs. Arnd Bergmann pointed out that the right fix is to make EDAC_SKX "depend on ACPI".

This contains a firmware "ioctl" interface that was a little controversial at first, but the version we merged solved that by not exposing arbitrary firmware calls to user space. - The Amlogic Meson platform gains a "canvas" driver that is used for video processing and shared between different high-level drivers. The rest is more of the usual, mostly related to SoC specific power management support and core drivers in drivers/soc: - Several Renesas SoCs (RZ/G1N, RZ/G2M, R-Car V3M, RZ/A2M) gain new features related to power and reset control. - The Mediatek mt8183 and mt6765 SoC platforms gain support for their respective power management chips. - A new driver for NXP i.MX8, which need a firmware interface for power management. - The SCPI firmware interface now contains support estimating power usage of performance states - The NVIDIA Tegra "pmc" driver gains a few new features, in particular a pinctrl interface for configuring the pads. - Lots of small changes for Qualcomm, in particular the "smem" device driver. - Some cleanups for the TI OMAP series related to their sysc controller.

New helpers for parsing DT cpu nodes and conversions to use the helpers. printk conversions to %pOFn for printing DT node names. Most went thru subystem trees, so this is the remainder. - Fixes to DT child node lookups to actually be restricted to child nodes instead of treewide. - Refactoring of dtb targets out of arch code. This makes the support more uniform and enables building all dtbs on c6x, microblaze, and powerpc. - Various DT binding updates for Renesas r8a7744 SoC - Vendor prefixes for Facebook, OLPC - Restructuring of some ARM binding docs moving some peripheral bindings out of board/SoC binding files - New "secure-chosen" binding for secure world settings on ARM - Dual licensing of 2 DT IRQ binding headers" * tag 'devicetree-for-4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: (78 commits) ARM: dt: relicense two DT binding IRQ headers power: supply: twl4030-charger: fix OF sibling-node lookup NFC: nfcmrvl_uart: fix OF child-node lookup net: stmmac: dwmac-sun8i: fix OF child-node lookup net: bcmgenet: fix OF child-node lookup drm/msm: fix OF child-node lookup drm/mediatek: fix OF sibling-node lookup of: Add missing exports of node name compare functions dt-bindings: Add OLPC vendor prefix dt-bindings: misc: bk4: Add device tree binding for Liebherr's BK4 SPI bus dt-bindings: thermal: samsung: Add SPDX license identifier dt-bindings: clock: samsung: Add SPDX license identifiers dt-bindings: timer: ostm: Add R7S9210 support dt-bindings: phy: rcar-gen2: Add r8a7744 support dt-bindings: can: rcar_can: Add r8a7744 support dt-bindings: timer: renesas, cmt: Document r8a7744 CMT support dt-bindings: watchdog: renesas-wdt: Document r8a7744 support dt-bindings: thermal: rcar: Add device tree support for r8a7744 Documentation: dt: Add binding for /secure-chosen/stdout-path dt-bindings: arm: zte: Move sysctrl bindings to their own doc ...

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use the for_each_of_cpu_node iterator to iterate over cpu nodes. This has the side effect of defaulting to iterating using "cpu" node names in preference to the deprecated (for FDT) device_type == "cpu". The error messages are removed in the process as it's not the driver's job to be checking cpu nodes. Any problems with cpu nodes should be noticed by the architecture code.

The compiler complains about one of the conversions: drivers/edac/altera_edac.c: In function 'altr_init_a10_ecc_block': drivers/edac/altera_edac.c:1053:10: error: cast to pointer from integer of \ different size [-Werror=int-to-pointer-cast] base = (void __iomem *)res.start; ^ drivers/edac/altera_edac.c: In function 'altr_edac_a10_probe': drivers/edac/altera_edac.c:2062:10: error: cast to pointer from integer of \ different size [-Werror=int-to-pointer-cast] base = (void __iomem *)res.start; Using a static checker probably also notices the __iomem cast. Solving this properly isn't trivial, but simply casting to a 'uintptr_t' instead of 'void __iomem *' makes it less wrong and should avoid the warnings.

| * | EDAC, sb_edac: Fix reporting for patrol scrubber errorsQiuxu Zhuo2018-09-111-6/+110
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sb_edac sometimes reports the wrong DIMM for a memory error found by the patrol scrubber. That is because the hardware provides only a 4KB page-aligned address for the error case. This means that the EDAC driver will point at the DIMM matching offset 0x0 in the 4KB page, but because of interleaving across channels and ranks, the actual DIMM involved may be different if the error is on some other cache line within the page. Therefore, reconstruct the socket/iMC/channel information from the "mce" structure passed to the EDAC driver. The DIMM cannot be determined, so pass "dimm=-1" to the EDAC core. It will report that all the DIMMs on that channel may be affected.

| * | EDAC, sb_edac: Return early on ADDRV bit and address type testQiuxu Zhuo2018-09-111-33/+35

EDAC drivers should check: 1) Is this a memory error? [bit 7 in status register] 2) Is there a valid address? [bit 58 in status register] 3) Is the address a system address? [bitfield 8:6 in misc register] The sb_edac driver performed test "1" twice. Waited far too long to perform check "2". Didn't do check "3" at all. Fix it by moving the test for valid address from sbridge_mce_output_error() into sbridge_mce_check_error() and add a test for the type immediately after. Delete the redundant check for the type of the error from sbridge_mce_output_error().
