06:25 <ariellea> hey, can some one help me as I feel like a bit of a newb. I cannot seem to get a working nv_uboot kernel combo working on my Chromebook Arm. I compiled up on the chromebook Linux 4.0 mainline using exynos_defconfig (I'm on debian so used make-kpkg)

06:26 <ariellea> however when ever I boot it from nv_uboot it resets, is there a prebuilt known good one that isn't the chromeos one I can use to at least get the booting part working

11:13 <Wizzup_> what chromebook?

13:57 <WarheadsSE> ^

14:22 <daniels> Wizzup_: you can't change the frequency of each core, no, only each set

14:24 <daniels> Wizzup_: apll and kpll are the functional clocks you change; see drivers/clk/samsung/clk-exynos5420.c

14:27 <daniels> which reminds me, need to re-post http://cgit.collabora.com/git/user/daniels/linux.git/commit/?h=wip/4.0.x/exynos-tegra-hwenable&id=884686c8f4f50ca90659fca2b30995d507009211

17:53 <prahal_> I do not get why size is set to coherent_dma_mask "+ 1" instead of plain coherent_dma_mask since commit 0c79c81c upstream ... It kills kitten as arch/arm/mm/dma-mapping.c checks the size for <= SIZE_MAX

17:53 <prahal_> that is arm_setup_iommu_dma_ops always exits and dma_ops are never iommu ones

17:59 <liquidAcid> prahal_, something like this? http://www.spinics.net/lists/linux-samsung-soc/msg44051.html

19:19 <prahal_> DMA_BIT_MASK(32) or 0xffffffff , yes .

19:24 <prahal_> +1 it is rejected by size check from https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=22b3c181c6c324a46f71aae806d8ddbe61d25761

19:30 <prahal_> against https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/drivers/of/device.c#n109 < coherent_dma_mask + 1 (where coherent_dma_mask equal 0xffffffff

19:32 <prahal_> there must be some rationale ... the +1 to 0xfffffff comes form the same author than the size must be below 0xfffffff

19:32 <prahal_> https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/of/device.c?id=0c79c81c779fe54e67c0ce8c1fda551ca57d8a35

20:37 <prahal_> thread at https://lkml.org/lkml/2014/12/23/344 <- I am still uneasy . Ended up relaxing the size check
