  • 6169a5cfa   ARC: build: move symlink creation to arch/arc/Makefile to avoid race ... Browse Code »

    [ Upstream commit c5e6ae563c802c4d828d42e134af64004db2e58c ]

    If you run 'make uImage uImage.gz' with the parallel option, uImage.gz
    will be created by two threads simultaneously.

    This is because arch/arc/Makefile does not specify the dependency
    between uImage and uImage.gz. Hence, GNU Make assumes they can be
    built in parallel. One thread descends into arch/arc/boot/ to create
    uImage, and another to create uImage.gz.

    Please notice the same log is displayed twice in the following steps:

    $ export CROSS_COMPILE=
    $ make -s ARCH=arc defconfig
    $ make -j$(nproc) ARCH=arc uImage uImage.gz
    [ snip ]
    LD vmlinux
    SORTTAB vmlinux
    SYSMAP System.map
    OBJCOPY arch/arc/boot/vmlinux.bin
    OBJCOPY arch/arc/boot/vmlinux.bin
    GZIP arch/arc/boot/vmlinux.bin.gz
    GZIP arch/arc/boot/vmlinux.bin.gz
    UIMAGE arch/arc/boot/uImage.gz
    UIMAGE arch/arc/boot/uImage.gz

    Image Type: ARC Linux Kernel Image (gzip compressed)

    Image Type: ARC Linux Kernel Image (gzip compressed)
    Data Size: 2815455 Bytes = 2749.47 KiB = 2.69 MiB
    Load Address: 80000000
    Entry Point: 80004000

    This is a race between the two threads trying to write to the same file
    arch/arc/boot/uImage.gz. This is a potential problem that can generate
    a broken file.

    I fixed a similar problem for ARM by commit 3939f3345050 ("ARM: 8418/1:
    add boot image dependencies to not generate invalid images").

    I highly recommend to avoid such build rules that cause a race condition.

    Move the uImage rule to arch/arc/Makefile.

    Another strangeness is that arch/arc/boot/Makefile compares the
    timestamps between $(obj)/uImage and $(obj)/uImage.*:

    $(obj)/uImage: $(obj)/uImage.$(suffix-y)
    @ln -sf $(notdir $

  • 26907eb60   ARC: [plat-hsdk]: Switch ethernet phy-mode to rgmii-id ... Browse Code »

    HSDK board has Micrel KSZ9031, recent commit
    bcf3440c6dd ("net: phy: micrel: add phy-mode support for the KSZ9031 PHY")
    caused a breakdown of Ethernet.
    Using 'phy-mode = "rgmii"' is not correct because accodring RGMII
    specification it is necessary to have delay on RX (PHY to MAX)
    which is not generated in case of "rgmii".
    Using "rgmii-id" adds necessary delay and solves the issue.

    Also adding name of PHY placed on HSDK board.

    Newer version of HSDK aka HSDK-4xD (with dual issue HS48x4 CPU) wired up
    the perf interrupt, so enable that in DT.
    This is OK for old HSDK where this irq is ignored because pct irq is not

  • 1681baa71   ARC: merge HAPS-HS with nSIM-HS configs ... Browse Code »

    Starting from nSIM 2019.06 is possible to use DW UART
    instead of ARC UART. That allows us to merge
    "nsim_hs" with "haps_hs" and "nsim_hs_smp" with "haps_hs_smp"
    with minor changes which were done in previous commits.

    We eliminate nsim_hs_defconfig and nsim_hs_smp_defconfig
    and leave haps_hs_defconfig and haps_hs_smp_defconfig
    which can be used on HAPS / nSIM / ZEBU / QEMU platforms
    without additional changes in Linux kernel.

    For nSIM we should now use UART property values
    "-prop=nsim_mem-dev=uart0,kind=dwuart,base=0xf0000000"
    instead of previously used
    "-prop=nsim_mem-dev=uart0,base=0xc0fc1000"
    "use_connect" and "irq" values of UART property remains untouched.

  • ce0eff0d9   ARC: [plat-hsdk]: allow to switch between AXI DMAC port configurations ... Browse Code »

    We want to use DW AXI DMAC on HSDK board in our automated verification
    to test cache & dma kernel code changes. This is perfect candidate
    as we don't depend on any external peripherals like MMC card / USB
    storage / etc.
    To increase test coverage we want to test both options:
    * DW AXI DMAC is connected through IOC port & dma direct ops used
    * DW AXI DMAC is connected to DDR port & dma noncoherent ops used

    Introduce 'arc_hsdk_axi_dmac_coherent' global variable which can be
    modified by debugger (same way as we patch 'ioc_enable') to switch
    between these options without recompiling the kernel.
    Depend on this value we tweak memory bridge configuration and
    "dma-coherent" DTS property of DW AXI DMAC.

  • 94b8beb97   ARC: [haps] Add Virtio support ... Browse Code »

    As a preparation for QEMU usage for ARC let's add basic Virtio-MMIO
    peripherals support for the platform we're going to use.

    For now we add 5 Virtio slots in .dts and enable block and network devices
    via Virtio-MMIO.

    Note even though typically Virtio register set fits in 0x200 bytes
    we "allocate" here 0x2000 so that it matches ARC's default 8KiB page size
    and so remapping of that area is done clearly.

    We also enable DEVTMPFS automount for more convenient use
    of external root file-stystem. Before that we used to use built-in
    Initramfs which didn't automount DEVTMPFS anyways so we didn't need
    that option, while now it starts making sense.

    Just to confirm this is what we get on FPGA prototype in the bootlog:
    | TI DP83867 stmmac-0:00: attached PHY driver [TI DP83867] ...

    On real board though we have Micrel KZS9031 PHY and we even have
    CONFIG_MICREL_PHY=y set in hsdk_defconfig. That's what we see in the bootlog:

  • 5c0920897   ARC: [plat-axs*/plat-hsdk]: Allow U-Boot to pass MAC-address to the kernel ... Browse Code »

    Otherwise kernel uses random MAC which is not very conveniet.
    With that change in place use might set desired MAC in U-Boot
    with "setenv ethaddr 11:22:33:44:55:66", save environment and
    then from boot to boot the same MAC will be used by the kernel.

    One other note for this to happen it's required to pass
    board's .dtb in U-Boot's "bootm" command like that:
    ------------------->8-----------------
    bootm 0x82000000 - 0x84000000
    ------------------->8-----------------

    Here 0x82000000 is location of uImage while
    0x80000000 is location of either axs10x.dtb or hsdk.dtb
    previously loaded from SD-card, USB storage or TFTP server.
