[opensuse-kernel] Maintenance update plan for openSUSE 13.2 kernel?
by Takashi Iwai 15 Dec '14

15 Dec '14

Hi, [maybe this had been already discussed somewhere but I couldn't find it, so...] What is the plan for (maintenance) updates of openSUSE 13.2 kernel? Will we stick with 3.16.x kernel, or will we upgrade to 3.17.x (and later one, eventually)? thanks, Takashi -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org

[opensuse-kernel] [PATCH RESEND] drm/tilcdc: Fix the error path in tilcdc_load()
by matwey.kornilov＠gmail.com 06 Nov '14

06 Nov '14

From: Ezequiel Garcia <ezequiel(a)vanguardiasur.com.ar> The current error path calls tilcdc_unload() in case of an error to release the resources. However, this is wrong because not all resources have been allocated by the time an error occurs in tilcdc_load(). To fix it, this commit adds proper labels to bail out at the different stages in the load function, and release only the resources actually allocated.

Kornilov <matwey.kornilov(a)gmail.com> --- Hi, This is to fix kernel OOPS on BeagleBone Black introduced by 3a49012224ca9016658a831a327ff6a7fe5bb4f9 (and its copies in stable trees). See https://bugzilla.kernel.org/show_bug.cgi?id=86071 for reference. Kernal 3.16.3+ and 3.17+ are affected. This commit is for stable and openSUSE-13.2 branches. It also has been sent to upstream stable, but has not been included into 3.16.7 which was the last release in 3.16.x branch. Because of this, it is needed to be applied to openSUSE-13.2 directly. diff --git a/drivers/gpu/drm/tilcdc/tilcdc_drv.c b/drivers/gpu/drm/tilcdc/tilcdc_drv.c index aea4b766..79a34cb 100644 --- a/drivers/gpu/drm/tilcdc/tilcdc_drv.c +++ b/drivers/gpu/drm/tilcdc/tilcdc_drv.c @@ -84,6 +84,7 @@ static int modeset_init(struct drm_device *dev) if ((priv->num_encoders == 0) || (priv->num_connectors == 0)) { /* oh nos! */ dev_err(dev->dev, "no encoders/connectors found\n"); + drm_mode_config_cleanup(dev); return -ENXIO; } @@ -172,33 +173,37 @@ static int tilcdc_load(struct drm_device *dev, unsigned long flags) dev->dev_private = priv; priv->wq = alloc_ordered_workqueue("tilcdc", 0); + if (!priv->wq) { + ret = -ENOMEM; + goto fail_free_priv; + } res = platform_get_resource(pdev, IORESOURCE_MEM, 0); if (!res) { dev_err(dev->dev, "failed to get memory resource\n"); ret = -EINVAL; - goto fail; + goto fail_free_wq; } priv->mmio = ioremap_nocache(res->start, resource_size(res)); if (!priv->mmio) { dev_err(dev->dev, "failed to ioremap\n"); ret = -ENOMEM; - goto fail; + goto fail_free_wq; } priv->clk = clk_get(dev->dev, "fck"); if (IS_ERR(priv->clk)) { dev_err(dev->dev, "failed to get functional clock\n"); ret = -ENODEV; - goto fail; + goto fail_iounmap; } priv->disp_clk = clk_get(dev->dev, "dpll_disp_ck"); if (IS_ERR(priv->clk)) { dev_err(dev->dev, "failed to get display clock\n"); ret = -ENODEV; - goto fail; + goto fail_put_clk; } #ifdef CONFIG_CPU_FREQ @@ -208,7 +213,7 @@ static int tilcdc_load(struct drm_device *dev, unsigned long flags) CPUFREQ_TRANSITION_NOTIFIER); if (ret) { dev_err(dev->dev, "failed to register cpufreq notifier\n"); - goto fail; + goto fail_put_disp_clk; } #endif @@ -253,13 +258,13 @@ static int tilcdc_load(struct drm_device *dev, unsigned long flags) ret = modeset_init(dev); if (ret < 0) { dev_err(dev->dev, "failed to initialize mode setting\n"); - goto fail; + goto fail_cpufreq_unregister; } ret = drm_vblank_init(dev, 1); if (ret < 0) { dev_err(dev->dev, "failed to initialize vblank\n"); - goto fail; + goto fail_mode_config_cleanup; } pm_runtime_get_sync(dev->dev); @@ -267,7 +272,7 @@ static int tilcdc_load(struct drm_device *dev, unsigned long flags) pm_runtime_put_sync(dev->dev); if (ret < 0) { dev_err(dev->dev, "failed to install IRQ handler\n"); - goto fail; + goto fail_vblank_cleanup; } platform_set_drvdata(pdev, dev); @@ -283,13 +288,48 @@ static int tilcdc_load(struct drm_device *dev, unsigned long flags) priv->fbdev = drm_fbdev_cma_init(dev, bpp, dev->mode_config.num_crtc, dev->mode_config.num_connector); + if (IS_ERR(priv->fbdev)) { + ret = PTR_ERR(priv->fbdev); + goto fail_irq_uninstall; + } drm_kms_helper_poll_init(dev); return 0; -fail: - tilcdc_unload(dev); +fail_irq_uninstall: + pm_runtime_get_sync(dev->dev); + drm_irq_uninstall(dev); + pm_runtime_put_sync(dev->dev); + +fail_vblank_cleanup: + drm_vblank_cleanup(dev); + +fail_mode_config_cleanup: + drm_mode_config_cleanup(dev); + +fail_cpufreq_unregister: + pm_runtime_disable(dev->dev); +#ifdef CONFIG_CPU_FREQ + cpufreq_unregister_notifier(&priv->freq_transition, + CPUFREQ_TRANSITION_NOTIFIER); +fail_put_disp_clk: + clk_put(priv->disp_clk); +#endif + +fail_put_clk: + clk_put(priv->clk); + +fail_iounmap: + iounmap(priv->mmio); + +fail_free_wq: + flush_workqueue(priv->wq); + destroy_workqueue(priv->wq); + +fail_free_priv: + dev->dev_private = NULL; + kfree(priv); return ret; } -- cgit v0.10.1 -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org

[opensuse-kernel] [RFC] arm64 backports for 3.16
by Alexander Graf 03 Nov '14

03 Nov '14

Hi kernel gurus, There were quite a good number of bug fixes and necessary features in post-3.16 as well as some patches that are missing upstream to make arm64 a shiny out of the box experience. I would like to shove the patches below into our openSUSE-13.2 branch. I have a properly trimmed down (and adjusted) version of the changes below based on 3.18 and an untested variant on top of 3.17. What is the strategy with 13.2 going to be? Are we going to uprev the kernel for it? Is it going to jump to 3.17, so should I push the changes here into the 13.2 branch the stable branch and the master branch? Or would master and 13.2 suffice? Also, if you think the changes below are too intrusive, please let me know. I've tried to double-check that they basically only touch arm64 specific code paths with a few shared ppc blocks. But the likelyhood for x86 breakage is low: .../devicetree/bindings/pci/xgene-pci.txt | 57 + MAINTAINERS | 8 + arch/arm/include/asm/io.h | 1 + arch/arm/include/asm/kvm_mmu.h | 25 + arch/arm/include/uapi/asm/kvm.h | 1 + arch/arm/kvm/arm.c | 23 +- arch/arm/kvm/mmu.c | 157 +- arch/arm/mach-integrator/pci_v3.c | 23 +- arch/arm64/Kconfig | 24 +- arch/arm64/boot/dts/apm-mustang.dts | 22 + arch/arm64/boot/dts/apm-storm.dtsi | 257 +- arch/arm64/crypto/Makefile | 2 +- arch/arm64/include/asm/Kbuild | 1 + arch/arm64/include/asm/io.h | 3 +- arch/arm64/include/asm/kvm_arm.h | 17 +- arch/arm64/include/asm/kvm_mmu.h | 90 + arch/arm64/include/asm/pci.h | 37 + arch/arm64/include/asm/pgtable.h | 2 + arch/arm64/include/uapi/asm/kvm.h | 1 + arch/arm64/kernel/Makefile | 1 + arch/arm64/kernel/efi-stub.c | 16 +- arch/arm64/kernel/entry-fpsimd.S | 2 +- arch/arm64/kernel/entry.S | 19 +- arch/arm64/kernel/fpsimd.c | 1 + arch/arm64/kernel/head.S | 6 +- arch/arm64/kernel/pci.c | 78 + arch/arm64/kvm/hyp-init.S | 20 +- arch/ia64/kernel/time.c | 15 - drivers/ata/ahci_xgene.c | 24 +- drivers/ata/libahci_platform.c | 12 + drivers/cpufreq/arm_big_little.c | 1 + drivers/irqchip/irq-gic.c | 24 +- drivers/net/ethernet/Kconfig | 1 + drivers/net/ethernet/Makefile | 1 + drivers/net/ethernet/amd/Makefile | 2 +- drivers/net/ethernet/amd/xgbe-a0/Makefile | 8 + drivers/net/ethernet/amd/xgbe-a0/xgbe-common.h | 1104 ++++++++ drivers/net/ethernet/amd/xgbe-a0/xgbe-dcb.c | 270 ++ drivers/net/ethernet/amd/xgbe-a0/xgbe-debugfs.c | 374 +++ drivers/net/ethernet/amd/xgbe-a0/xgbe-desc.c | 566 +++++ drivers/net/ethernet/amd/xgbe-a0/xgbe-dev.c | 2643 ++++++++++++++++++++ drivers/net/ethernet/amd/xgbe-a0/xgbe-drv.c | 1864 ++++++++++++++ drivers/net/ethernet/amd/xgbe-a0/xgbe-ethtool.c | 544 ++++ drivers/net/ethernet/amd/xgbe-a0/xgbe-main.c | 566 +++++ drivers/net/ethernet/amd/xgbe-a0/xgbe-mdio.c | 330 +++ drivers/net/ethernet/amd/xgbe-a0/xgbe-ptp.c | 285 +++ drivers/net/ethernet/amd/xgbe-a0/xgbe.h | 769 ++++++ drivers/net/ethernet/apm/Kconfig | 1 + drivers/net/ethernet/apm/Makefile | 5 + drivers/net/ethernet/apm/xgene/Kconfig | 10 + drivers/net/ethernet/apm/xgene/Makefile | 7 + .../net/ethernet/apm/xgene/xgene_enet_ethtool.c | 150 ++ drivers/net/ethernet/apm/xgene/xgene_enet_hw.c | 743 ++++++ drivers/net/ethernet/apm/xgene/xgene_enet_hw.h | 325 +++ drivers/net/ethernet/apm/xgene/xgene_enet_main.c | 1006 ++++++++ drivers/net/ethernet/apm/xgene/xgene_enet_main.h | 163 ++ drivers/net/ethernet/apm/xgene/xgene_enet_sgmac.c | 389 +++ drivers/net/ethernet/apm/xgene/xgene_enet_sgmac.h | 41 + drivers/net/ethernet/apm/xgene/xgene_enet_xgmac.c | 332 +++ drivers/net/ethernet/apm/xgene/xgene_enet_xgmac.h | 53 + drivers/net/fddi/skfp/h/skfbi.h | 5 - drivers/net/phy/Makefile | 1 + drivers/net/phy/amd-xgbe-a0-phy.c | 1445 +++++++++++ drivers/of/address.c | 154 ++ drivers/of/of_pci.c | 142 ++ drivers/pci/host/Kconfig | 10 + drivers/pci/host/Makefile | 1 + drivers/pci/host/pci-tegra.c | 10 +- drivers/pci/host/pci-xgene.c | 659 +++++ drivers/pci/host/pcie-rcar.c | 21 +- drivers/pci/pci.c | 40 + drivers/pci/probe.c | 11 +- drivers/power/reset/Kconfig | 12 +- drivers/power/reset/Makefile | 2 +- drivers/power/reset/syscon-reboot.c | 88 + drivers/power/reset/xgene-reboot.c | 103 - drivers/rtc/Kconfig | 2 +- drivers/rtc/Makefile | 4 + drivers/rtc/rtc-efi-platform.c | 31 + drivers/usb/host/Kconfig | 7 + drivers/usb/host/Makefile | 1 + drivers/usb/host/ehci-h20ahb.c | 341 +++ include/asm-generic/io.h | 2 +- include/asm-generic/pgtable.h | 4 + include/linux/irqchip/arm-gic.h | 3 + include/linux/of_address.h | 27 +- include/linux/of_pci.h | 13 + include/linux/pci.h | 27 + virt/kvm/arm/vgic.c | 18 + 89 files changed, 16404 insertions(+), 302 deletions(-) Best case would be if we could shove this into the 13.2 release kernel still, as with the state that we have not a single arm64 board would work to an extent where it's actually usable. If that's impossible, I guess we'd have to improvise with overloaded kernel packages on arm64.

I remember patch for grub posted on grub-devel recently that disables graphic handover (thus forcing kernel to start in text mode), but it looks more like a workaround.

[opensuse-kernel] Splitting kernel-docs-pdf and kernel-docs-html subpackages
by Takashi Iwai 30 Oct '14

30 Oct '14

Hi, does anyone have objection to split two more subpackages from kernel-docs package, dedicated for PDF and HTML documents, respectively? In my plan, kenrel-docs will keep man pages and some basic files like COPYING, MAINTAINERS, README, etc, for compatibility. Luckily, since openSUSE 13.2 kernel-docs package contains no PDF file (and doesn't generate HTML files), we don't care much about package split-updates. thanks, Takashi -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org

[opensuse-kernel] UEFI booting to kernel 3.17.x -- signature verification failed
by Atri Bhattacharya 29 Oct '14

29 Oct '14

Hi! I installed kernel-desktop (3.17.0) from Kernel:Stable on my UEFI laptop using openSUSE 13.2 RC, but am unable to boot into it because it complains of an invalid signature at boot* and drops me back to the grub screen. Is there a way to be able to boot into kernels installed from Kernel:Stable on UEFI systems? Thanks for any help. Best wishes. * Something along the lines of "/boot/vmzlinux-3.17.0-1.1.gc467423 has invalid signature" -- Atri Bhattacharya -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org

by Joshua Schmid 27 Oct '14

From: Oliver Neukum <oneukum(a)novell.com> The switch back is limited to ULT even on HP. The contrary finding arose by bad luck in BIOS versions for testing.
