2016-09-21md: changes for MD_STILL_CLOSED flagGuoqing Jiang
When stop clustered raid while it is pending on resync, MD_STILL_CLOSED flag could be cleared since udev rule is triggered to open the mddev. So obviously array can't be stopped soon and returns EBUSY. mdadm -Ss md-raid-arrays.rules set MD_STILL_CLOSED md_open() ... ... ... clear MD_STILL_CLOSED do_md_stop We make below changes to resolve this issue: 1. rename MD_STILL_CLOSED to MD_CLOSING since it is set when stop array and it means we are stopping array. 2. let md_open returns early if CLOSING is set, so no other threads will open array if one thread is trying to close it. 3. no need to clear CLOSING bit in md_open because 1 has ensure the bit is cleared, then we also don't need to test CLOSING bit in do_md_stop.

2016-09-21i2c-eg20t: fix race between i2c init and interrupt enableYadi.hu
the eg20t driver call request_irq() function before the pch_base_address, base address of i2c controller's register, is assigned an effective value. there is one possible scenario that an interrupt which isn't inside eg20t arrives immediately after request_irq() is executed when i2c controller shares an interrupt number with others. since the interrupt handler pch_i2c_handler() has already active as shared action, it will be called and read its own register to determine if this interrupt is from itself. At that moment, since base address of i2c registers is not remapped in kernel space yet,so the INT handler will access an illegal address and then a error occurs.

2016-09-21Input: serio - add hangup supportHans Verkuil
The Pulse-Eight USB CEC adapter is a usb device that shows up as a ttyACM0 device. It requires that you run inputattach in order to communicate with it via serio. This all works well, but it would be nice to have a udev rule to automatically start inputattach. That too works OK, but the problem comes when the USB device is unplugged: the tty hangup is never handled by the serio framework so the inputattach utility never exits and you have to kill it manually. By adding this hangup callback the inputattach utility now properly exits as soon as the USB device is unplugged. The udev rule I used on my Debian sid system is: SUBSYSTEM=="tty", KERNEL=="ttyACM[0-9]*", ATTRS{idVendor}=="2548", ATTRS{idProduct}=="1002", ACTION=="add", TAG+="systemd", ENV{SYSTEMD_WANTS}+="pulse8-cec-inputattach@%k.service" And /etc/systemd/system/pulse8-cec-inputattach@.service is as follows: =============================================================== [Unit] Description=inputattach for pulse8-cec device on %I [Service] Type=simple ExecStart=/usr/local/bin/inputattach --pulse8-cec /dev/%I KillMode=process =============================================================== Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Tested-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

2016-09-21lightnvm: expose device geometry through sysfsSimon A. F. Lund
For a host to access an Open-Channel SSD, it has to know its geometry, so that it writes and reads at the appropriate device bounds. Currently, the geometry information is kept within the kernel, and not exported to user-space for consumption. This patch exposes the configuration through sysfs and enables user-space libraries, such as liblightnvm, to use the sysfs implementation to get the geometry of an Open-Channel SSD. The sysfs entries are stored within the device hierarchy, and can be found using the "lightnvm" device type. An example configuration looks like this: /sys/class/nvme/ └── nvme0n1 ├── capabilities: 3 ├── device_mode: 1 ├── erase_max: 1000000 ├── erase_typ: 1000000 ├── flash_media_type: 0 ├── media_capabilities: 0x00000001 ├── media_type: 0 ├── multiplane: 0x00010101 ├── num_blocks: 1022 ├── num_channels: 1 ├── num_luns: 4 ├── num_pages: 64 ├── num_planes: 1 ├── page_size: 4096 ├── prog_max: 100000 ├── prog_typ: 100000 ├── read_max: 10000 ├── read_typ: 10000 ├── sector_oob_size: 0 ├── sector_size: 4096 ├── media_manager: gennvm ├── ppa_format: 0x380830082808001010102008 ├── vendor_opcode: 0 ├── max_phys_secs: 64 └── version: 1 Signed-off-by: Simon A.

2016-09-21lightnvm: control life of nvm_dev in driverMatias Bjørling
LightNVM compatible device drivers does not have a method to expose LightNVM specific sysfs entries. To enable LightNVM sysfs entries to be exposed, lightnvm device drivers require a struct device to attach it to. To allow both the actual device driver and lightnvm sysfs entries to coexist, the device driver tracks the lifetime of the nvm_dev structure. This patch refactors NVMe and null_blk to handle the lifetime of struct nvm_dev, which eliminates the need for struct gendisk when a lightnvm compatible device is provided.

2016-09-21null_blk: refactor to support non-gendisk devicesMatias Bjørling
With LightNVM enabled devices, the gendisk structure is not exposed to the user. This hides the device driver specific sysfs entries, and prevents binding of LightNVM geometry information to the device.

2016-09-21nvme: refactor namespaces to support non-gendisk devicesMatias Bjørling
With LightNVM enabled namespaces, the gendisk structure is not exposed to the user. This prevents LightNVM users from accessing the NVMe device driver specific sysfs entries, and LightNVM namespace geometry. Refactor the revalidation process, so that a namespace, instead of a gendisk, is revalidated. This later allows patches to wire up the sysfs entries up to a non-gendisk namespace.

2016-09-21drm/rockchip: Kill vop_plane_stateTomasz Figa

2016-09-21drm/rockchip: Always signal event in next vblank after cfg_doneTomasz Figa
This patch makes the driver send the pending vblank event in next vblank following the commit, relying on vblank signalling improvements done in previous patches. This gives us vblank events that always represent the real moment of changes hitting on the screen (which was the case only for complete FB changes before) and lets us remove the manual window update check. Signed-off-by: Tomasz Figa <tfiga@chromium.org>
2016-09-21drm/rockchip: Do not enable vblank without eventTomasz Figa
Originally we needed to enable vblank for any atomic commit to kick the PSR machine, but that was changed and we no longer need to do so from a vblank interrupt. Let's return to original behavior of enabling vblank only if it is really necessary. This essentially reverts commit 5b6804034ae9 ("drm/rockchip: Enable vblank without event"). Signed-off-by: Tomasz Figa <tfiga@chromium.org>
2016-09-21drm/rockchip: Replace custom wait_for_vblanks with helperTomasz Figa
Currently the driver uses a custom function to wait for flip to complete after an atomic commit. It was needed before because of two problems: - there is no hardware vblank counter, so the original helper would have a race condition with the vblank interrupt, - the driver didn't support unreferencing cursor framebuffers asynchronously to the commit, which was what the helper expected. Since both problems have been solved by previous patches, we can now make the driver use the generic helper and remove custom waiting code. Signed-off-by: Tomasz Figa <tfiga@chromium.org>
2016-09-21drm/rockchip: Unreference framebuffers from flip workTomasz Figa
Currently the driver waits for vblank and then unreferences old framebuffers from atomic commit code path. This is however breaking the legacy cursor API, which requires the updates to be fully asynchronous. Instead of just adding a special case for cursor, we can have actually smaller amount of code to unreference any changed framebuffer from a flip work. Signed-off-by: Tomasz Figa <tfiga@chromium.org>
2016-09-21drm/rockchip: Avoid race with vblank count incrementTomasz Figa
Since VOP does not have a hardware vblank count register, the ongoing commit might be racing with a requested vblank interrupt, which would increment the software vblank counter before the changes being committed actually happen. To avoid this, we can extend .atomic_flush(), so after it sets cfg_done bit, it polls the vblank interrupt bit until it's inactive to make sure that any old vblank interrupt gets to the handler and then uses synchronize_irq(vop->irq) to make sure the handler finishes running. The polling case should happen very rarely, but even if, the total wait time should be relatively low and in practice almost equal to the vop hardirq handler running time.

2016-09-21drm/rockchip: Get rid of some unnecessary codeTomasz Figa

2016-09-21drm/rockchip: Clear interrupt status bits before enablingTomasz Figa
The enable register only masks the raw status bits to signal CPU interrupt only for enabled interrupts. The status bits are activated regardless of the enable register. This means that we might have an old interrupt event queued, which we are not interested in. To avoid getting a spurious interrupt signalled, we have to clear the old bit before we update the enable register. Signed-off-by: Tomasz Figa <tfiga@chromium.org>

2016-09-21net: can: ifi: Configure transmitter delayMarek Vasut
Configure the transmitter delay register at +0x1c to correctly handle the CAN FD bitrate switch (BRS). This moves the SSP (secondary sample point) to a proper offset, so that the TDC mechanism works and won't generate error frames on the CAN link.
