patch "USB: leds: fix regression in usbport led trigger" added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled USB: leds: fix regression in usbport led trigger to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From 91f7d2e89868fcac0e750a28230fdb1ad4512137 Mon Sep 17 00:00:00 2001 From: Christian Lamparter <chunkeey(a)gmail.com> Date: Fri, 11 Jan 2019 17:29:45 +0100 Subject: USB: leds: fix regression in usbport led trigger The patch "usb: simplify usbport trigger" together with "leds: triggers: add device attribute support" caused an regression for the usbport trigger. it will no longer enumerate any active usb hub ports under the "ports" directory in the sysfs class directory, if the usb host drivers are fully initialized before the usbport trigger was loaded. The reason is that the usbport driver tries to register the sysfs entries during the activate() callback. And this will fail with -2 / ENOENT because the patch "leds: triggers: add device attribute support" made it so that the sysfs "ports" group was only being added after the activate() callback succeeded. This version of the patch reverts parts of the "usb: simplify usbport trigger" patch and restores usbport trigger's functionality.

[PATCH] genirq/affinity: Assign default affinity to pre/post vectors

by Huacai Chen

Generally, irq_create_affinity_masks() assign default affinity to pre/ post vectors correctly. However, it ignore the case that there are only pre/post vectors (when nvecs == affd->pre_vectors + affd->post_vectors) and return NULL. This case usually happens when nvecs = 1 (e.g. in nvme driver when MSI-X is unavailable and fallback to MSI) and will trigger the warning in pci_irq_get_affinity(). This patch fix the corner case.

[PATCH v2] media: vimc: Add vimc-streamer for stream control

by Lucas A. M. Magalhaes

Add a linear pipeline logic for the stream control. It's created by walking backwards on the entity graph. When the stream starts it will simply loop through the pipeline calling the respective process_frame function of each entity. Fixes: f2fe89061d797 ("vimc: Virtual Media Controller core, capture and sensor") Cc: stable(a)vger.kernel.org # for v4.20 Signed-off-by: Lucas A. M. Magalhães <lucmaga(a)gmail.com> --- The actual approach for streaming frames on vimc uses a recursive logic[1]. This algorithm may cause problems as the stack usage increases a with the topology. For the actual topology almost 1Kb of stack is used if compiled with KASAN on a 64bit architecture. However the topology is fixed and hard-coded on vimc-core[2]. So it's a controlled situation if used as is. [1] The stream starts on vim-sensor's thread https://git.linuxtv.org/media_tree.git/tree/drivers/media/platform/vimc/vim… It proceeds calling successively vimc_propagate_frame https://git.linuxtv.org/media_tree.git/tree/drivers/media/platform/vimc/vim… Then processes_frame on the next entity https://git.linuxtv.org/media_tree.git/tree/drivers/media/platform/vimc/vim… https://git.linuxtv.org/media_tree.git/tree/drivers/media/platform/vimc/vim… This goes until the loop ends on a vimc-capture device https://git.linuxtv.org/media_tree.git/tree/drivers/media/platform/vimc/vim… [2]https://git.linuxtv.org/media_tree.git/tree/drivers/media/platform/vimc/v… drivers/media/platform/vimc/Makefile | 3 +- drivers/media/platform/vimc/vimc-capture.c | 18 +- drivers/media/platform/vimc/vimc-common.c | 35 ---- drivers/media/platform/vimc/vimc-common.h | 15 +- drivers/media/platform/vimc/vimc-debayer.c | 26 +-- drivers/media/platform/vimc/vimc-scaler.c | 28 +-- drivers/media/platform/vimc/vimc-sensor.c | 56 ++---- drivers/media/platform/vimc/vimc-streamer.c | 197 ++++++++++++++++++++ drivers/media/platform/vimc/vimc-streamer.h | 38 ++++ 9 files changed, 269 insertions(+), 147 deletions(-) create mode 100644 drivers/media/platform/vimc/vimc-streamer.c create mode 100644 drivers/media/platform/vimc/vimc-streamer.h diff --git a/drivers/media/platform/vimc/Makefile b/drivers/media/platform/vimc/Makefile index 4b2e3de7856e..c4fc8e7d365a 100644 --- a/drivers/media/platform/vimc/Makefile +++ b/drivers/media/platform/vimc/Makefile @@ -5,6 +5,7 @@ vimc_common-objs := vimc-common.o vimc_debayer-objs := vimc-debayer.o vimc_scaler-objs := vimc-scaler.o vimc_sensor-objs := vimc-sensor.o +vimc_streamer-objs := vimc-streamer.o obj-$(CONFIG_VIDEO_VIMC) += vimc.o vimc_capture.o vimc_common.o vimc-debayer.o \ - vimc_scaler.o vimc_sensor.o + vimc_scaler.o vimc_sensor.o vimc_streamer.o diff --git a/drivers/media/platform/vimc/vimc-capture.c b/drivers/media/platform/vimc/vimc-capture.c index 3f7e9ed56633..80d7515ec420 100644 --- a/drivers/media/platform/vimc/vimc-capture.c +++ b/drivers/media/platform/vimc/vimc-capture.c @@ -24,6 +24,7 @@ #include <media/videobuf2-vmalloc.h> #include "vimc-common.h" +#include "vimc-streamer.h" #define VIMC_CAP_DRV_NAME "vimc-capture" @@ -44,7 +45,7 @@ struct vimc_cap_device { spinlock_t qlock;

[PATCH v2] media: imx-csi: Input connections to CSI should be optional

by Steve Longerbeam

Some imx platforms do not have fwnode connections to all CSI input ports, and should not be treated as an error. This includes the imx6q SabreAuto, which has no connections to ipu1_csi1 and ipu2_csi0. Return -ENOTCONN in imx_csi_parse_endpoint() so that v4l2-fwnode endpoint parsing will not treat an unconnected CSI input port as an error.

[PATCH] kbuild: mark prepare0 as PHONY to fix external module build

by Masahiro Yamada

Commit c3ff2a5193fa ("powerpc/32: add stack protector support") caused kernel panic on PowerPC if an external module is used with CONFIG_STACKPROTECTOR because the 'prepare' target was not executed for the external module build. Commit e07db28eea38 ("kbuild: fix single target build for external module") turned it into a build error because the 'prepare' target is now executed but the 'prepare0' target is missing for the external module build. External module on arm/arm64 with CONFIG_STACKPROTECTOR_PER_TASK is also broken in the same way. Move 'PHONY += prepare0' to the common place. Make is fine with missing rule for phony targets. I minimize the change so it can be easily backported to 4.20.x To fix v4.20 for external modules of PowerPC, please backport e07db28eea38 ("kbuild: fix single target build for external module"), and then this commit.

[PATCH] dmaengine: usb-dmac: Make DMAC system sleep callbacks explicit

by Yoshihiro Shimoda

From: Phuong Nguyen <phuong.nguyen.xw(a)renesas.com> This commit fixes the issue that USB-DMAC hangs silently after system resumes on R-Car Gen3 hence renesas_usbhs will not work correctly when using USB-DMAC for bulk transfer e.g. ethernet or serial gadgets. The issue can be reproduced by these steps: 1. modprobe g_serial 2. Suspend and resume system. 3. connect a usb cable to host side 4. Transfer data from Host to Target 5. cat /dev/ttyGS0 (Target side) 6. echo "test" > /dev/ttyACM0 (Host side) The 'cat' will not result anything. However, system still can work normally. Currently, USB-DMAC driver does not have system sleep callbacks hence this driver relies on the PM core to force runtime suspend/resume to suspend and reinitialize USB-DMAC during system resume. After the commit 17218e0092f8 ("PM / genpd: Stop/start devices without pm_runtime_force_suspend/resume()"), PM core will not force runtime suspend/resume anymore so this issue happens. To solve this, make system suspend resume explicit by using pm_runtime_force_{suspend,resume}() as the system sleep callbacks. SET_NOIRQ_SYSTEM_SLEEP_PM_OPS()is used to make sure USB-DMAC suspended after and initialized before renesas_usbhs."

[PATCH] Input: olpc_apsp - assign priv->dev earlier

The dev field needs to be set when serio_register_port() is called, because the open callback may use it (in the error handling path).
