SPI regression seen on ARM am335x in kernel 6.12.8 and 6.6.71

by Lars Pedersen

Hi. We have discovered an SPI regression when upgrading from 6.1.99 to a newer LTS version. Same error on kernel 6.6.71 and 6.12.8. I think we have identified the problem down to the reference clock calculation that seems to end up to zero in the spi-omap2-mcspi driver. Also we think it relates to commit 4c6ac5446d060f0bf435ccc8bc3aa7b7b5f718ad, where OMAP2_MCSPI_MAX_FREQ is used as fallback on error. In our case it seems to hit the else case. Snippets for device tree, spi-omap2-mcspi driver and kernel divide by zero error log with dynamic debug enabled. /Lars Pedersen diff --git a/drivers/spi/spi-omap2-mcspi.c b/drivers/spi/spi-omap2-mcspi.c index 67441b2cd603..8fedfc7db1fa 100644 --- a/drivers/spi/spi-omap2-mcspi.c +++ b/drivers/spi/spi-omap2-mcspi.c @@ -1559,12 +1559,13 @@ static int omap2_mcspi_probe(struct platform_device *pdev) dev_err(&pdev->dev, "Cannot request IRQ"); goto free_ctlr; } - + dev_dbg(&pdev->dev, "DEBUG_EXTRA pre calc\n"); mcspi->ref_clk = devm_clk_get_optional_enabled(&pdev->dev, NULL); if (IS_ERR(mcspi->ref_clk)) mcspi->ref_clk_hz = OMAP2_MCSPI_MAX_FREQ; else mcspi->ref_clk_hz = clk_get_rate(mcspi->ref_clk); + dev_dbg(&pdev->dev, "DEBUG_EXTRA: ref_clk_hz %d\n", mcspi->ref_clk_hz); ctlr->max_speed_hz = mcspi->ref_clk_hz; ctlr->min_speed_hz = mcspi->ref_clk_hz >> 15; ---8<--- /dts-v1/; #include "am33xx.dtsi" #include <dt-bindings/interrupt-controller/irq.h> ... &spi0 { status = "okay"; pinctrl-names = "default"; pinctrl-0 = <&spi0_pins_default>; ti,spi-num-cs = <1>; flash@0 { compatible = "jedec,spi-nor"; reg = <0>; spi-tx-bus-width = <1>; spi-rx-bus-width = <1>; spi-max-frequency = <10000000>; partitions { compatible = "fixed-partitions"; #address-cells = <1>; #size-cells = <1>; partition@0 { reg = <0x0 0x1f00000>; label = "radio-program"; }; partition@1f00000 { reg = <0x1f00000 0xe0000>; label = "linux-data"; read-only; }; partition@1fe0000 { reg = <0x1fe0000 0x10000>; label = "radio-config"; read-only; }; partition@1ff0000 { reg = <0x1ff0000 0x10000>; label = "baseband-config"; read-only; }; }; }; }; ---8<--- Jan 16 11:30:53 ptxdist kernel: omap2_mcspi 48030000.spi: DEBUG_EXTRA pre calc Jan 16 11:30:54 ptxdist kernel: omap2_mcspi 48030000.spi: DEBUG_EXTRA: ref_clk_hz 0 Jan 16 11:30:54 ptxdist kernel: omap2_mcspi 48030000.spi: registered host spi0 Jan 16 11:30:54 ptxdist kernel: Division by zero in kernel.

[PATCH] net/ncsi: wait for the last response to Deselect Package before configuring channel

by Paul Fertser

The NCSI state machine as it's currently implemented assumes that transition to the next logical state is performed either explicitly by calling `schedule_work(&ndp->work)` to re-queue itself or implicitly after processing the predefined (ndp->pending_req_num) number of replies. Thus to avoid the configuration FSM from advancing prematurely and getting out of sync with the process it's essential to not skip waiting for a reply. This patch makes the code wait for reception of the Deselect Package response for the last package probed before proceeding to channel configuration. Thanks go to Potin Lai and Cosmo Chou for the initial investigation and testing.

[PATCH v2] drm/i915: Fix page cleanup on DMA remap failure

by Brian Geffon

When converting to folios the cleanup path of shmem_get_pages() was missed. When a DMA remap fails and the max segment size is greater than PAGE_SIZE it will attempt to retry the remap with a PAGE_SIZEd segment size. The cleanup code isn't properly using the folio apis and as a result isn't handling compound pages correctly. v1 -> v2: (Ville) Fixed locations where we were not clearing mapping unevictable.
