Message-Id: <1387845593-10050-1-git-send-email-sboyd@codeaurora.org> Date: Mon, 23 Dec 2013 16:39:44 -0800 From: Stephen Boyd <sboyd@...eaurora.org> To: linux-arm-kernel@...ts.infradead.org Cc: David Brown <davidb@...eaurora.org>, Rohit Vaswani <rvaswani@...eaurora.org>, linux-kernel@...r.kernel.org, linux-arm-msm@...r.kernel.org, Kumar Gala <galak@...eaurora.org>, devicetree@...r.kernel.org, Mark Rutland <mark.rutland@....com>, Arnd Bergmann <arnd@...db.de>, Russell King <linux@....linux.org.uk> Subject: [PATCH v2 0/9] CPU enable method based SMP/hotplug + MSM conversion This is a rework of patches sent a months back by Rohit[1]. The goal of these patches is to add support for SMP and (basic) hotplug on MSM based SoCs. To get there, we add support for a generic way to hook in SMP/hotplug support code based on DT. To show how it's used, we convert the MSM8660 SMP support code over to the new method. After that we add support for the rest of the upstream MSM SoCs (note these patches are piled high on top of Rohit's patches to add 8074 support to MSM[2] and my follow ups[3,4], but this should only matter to the MSM maintainers). This is one of the last items of code that still requires us to have a mach directory and a machine descriptor. We should be able to move the hotplug/smp code out of mach directories if this approach is accepted. Changes since v1: * Added pointers from cpu nodes to saw and acc nodes * Squashed nr_cpus removal into reorganization patch * Reworked bindings/documentation * Rebased onto v3.13-rc4 [1] https://lkml.org/lkml/2013/8/1/770 [2] https://lkml.org/lkml/2013/10/17/520 [3] https://lkml.org/lkml/2013/10/18/406 [4] http://lkml.org/lkml/2013/10/28/501 Rohit Vaswani (6): devicetree: bindings: Document Krait/Scorpion cpus and enable-method ARM: msm: Remove pen_release usage ARM: msm: Re-organize platsmp to make it extensible ARM: msm: Add SMP support for KPSSv1 ARM: msm: Add SMP support for KPSSv2 ARM: dts: msm: Add nodes necessary for SMP boot Stephen Boyd (3): devicetree: bindings: Document qcom,kpss-acc devicetree: bindings: Document qcom,saw2 node ARM: Introduce CPU_METHOD_OF_DECLARE() for cpu hotplug/smp Documentation/devicetree/bindings/arm/cpus.txt | 25 +- .../devicetree/bindings/arm/msm/qcom,kpss-acc.txt | 30 ++ .../devicetree/bindings/arm/msm/qcom,saw2.txt | 35 ++ arch/arm/boot/dts/qcom-msm8660-surf.dts | 24 ++ arch/arm/boot/dts/qcom-msm8960-cdp.dts | 52 +++ arch/arm/boot/dts/qcom-msm8974.dtsi | 69 ++++ arch/arm/include/asm/smp.h | 9 + arch/arm/kernel/devtree.c | 40 +++ arch/arm/mach-msm/Makefile | 2 +- arch/arm/mach-msm/board-dt.c | 14 - arch/arm/mach-msm/common.h | 1 - arch/arm/mach-msm/headsmp.S | 39 --- arch/arm/mach-msm/hotplug.c | 31 +- arch/arm/mach-msm/platsmp.c | 371 ++++++++++++++++----- arch/arm/mach-msm/scm-boot.h | 8 +- include/asm-generic/vmlinux.lds.h | 10 + 16 files changed, 595 insertions(+), 165 deletions(-) create mode 100644 Documentation/devicetree/bindings/arm/msm/qcom,kpss-acc.txt create mode 100644 Documentation/devicetree/bindings/arm/msm/qcom,saw2.txt delete mode 100644 arch/arm/mach-msm/headsmp.S -- The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum, hosted by The Linux Foundation -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
