2020-05-06HID: asus: Add report_size to struct asus_touchpad_infoHans de Goede
Add the report_size to struct asus_touchpad_info instead of calculating it. This is a preparation patch for adding support for the multi-touch touchpad found on the Medion Akoya E1239T's keyboard-dock, which uses the same custom multi-touch protocol as the Asus keyboard-docks (same chipset vendor, Integrated Technology Express / ITE). The only difference in that the Akoya E1239T keyboard-dock's input-reports have a 5 byte footer instead of a 1 byte footer, which requires the report_size to be configurable per touchpad-model.

2020-05-06HID: asus: Add hid_is_using_ll_driver(usb_hid_driver) checkHans de Goede
Add a hid_is_using_ll_driver(usb_hid_driver) check to ensure that the parent device is an usb_interface, before casting the parent device pointer to an usb_interface pointer with to_usb_interface(). Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2020-05-06HID: asus: Simplify skipping of mappings for Asus T100CHI keyboard-dockHans de Goede
Before this commit the code was trying to keep the mapping for the left mouse-button, do avoid the hidinput_has_been_populated() check in hid-input.c from triggering and causing the touchpad input_dev ro get cleaned up. But the hidinput_has_been_populated() check happens after the input_configured callback which sets up all the input bit for the touchpad, so there is no need to preserve the left button mapping.

2020-05-06HID: asus: Only set EV_REP if we are adding a mappingHans de Goede
Make asus_input_mapping() only set EV_REP if we are adding a mapping. The T100CHI bluetooth keyboard dock has a few input reports for which we do not create any mappings (these input-reports are present in the descriptors but never send). The hid-asus code relies on the HID core not creating input devices for input-reports without any mappings. But the present of the EV_REP but counts as a mapping causing 6 /dev/input/event# nodes to be created for the T100CHI bluetooth keyboard dock. This change brings the amount of created /dev/input/event# nodes / input-devices down to 4. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2020-05-04gcc-10 warnings: fix low-hanging fruitLinus Torvalds
Due to a bug-report that was compiler-dependent, I updated one of my machines to gcc-10. That shows a lot of new warnings. Happily they seem to be mostly the valid kind, but it's going to cause a round of churn for getting rid of them.. This is the really low-hanging fruit of removing a couple of zero-sized arrays in some core code. We have had a round of these patches before, and we'll have many more coming, and there is nothing special about these except that they were particularly trivial, and triggered more warnings than most.

2020-05-02vhost: vsock: kick send_pkt worker once device is startedJia He
Ning Bo reported an abnormal 2-second gap when booting Kata container [1]. The unconditional timeout was caused by VSOCK_DEFAULT_CONNECT_TIMEOUT of connecting from the client side. The vhost vsock client tries to connect an initializing virtio vsock server. The abnormal flow looks like: host-userspace vhost vsock guest vsock ============== =========== ============ connect() --------> vhost_transport_send_pkt_work() initializing | vq->private_data==NULL | will not be queued V schedule_timeout(2s) vhost_vsock_start() <--------- device ready set vq->private_data wait for 2s and failed connect() again vq->private_data!=NULL recv connecting pkt Details: 1. Host userspace sends a connect pkt, at that time, guest vsock is under initializing, hence the vhost_vsock_start has not been called. So vq->private_data==NULL, and the pkt is not been queued to send to guest 2. Then it sleeps for 2s 3. After guest vsock finishes initializing, vq->private_data is set 4. When host userspace wakes up after 2s, send connecting pkt again, everything is fine. As suggested by Stefano Garzarella, this fixes it by additional kicking the send_pkt worker in vhost_vsock_start once the virtio device is started. This makes the pending pkt sent again. After this patch, kata-runtime (with vsock enabled) boot time is reduced from 3s to 1s on a ThunderX2 arm64 server.

Fix these issues by protecting vblk->vdev with a mutex and reference counting vblk so the vd_index_ida index can be removed in all cases.

2020-05-01iommu/amd: Fix legacy interrupt remapping for x2APIC-enabled systemSuravee Suthikulpanit
Currently, system fails to boot because the legacy interrupt remapping mode does not enable 128-bit IRTE (GA), which is required for x2APIC support. Fix by using AMD_IOMMU_GUEST_IR_LEGACY_GA mode when booting with kernel option amd_iommu_intr=legacy instead. The initialization logic will check GASup and automatically fallback to using AMD_IOMMU_GUEST_IR_LEGACY if GA mode is not supported.

2020-04-30io_uring: use cond_resched() in io_ring_ctx_wait_and_kill()Xiaoguang Wang
While working on to make io_uring sqpoll mode support syscalls that need struct files_struct, I got cpu soft lockup in io_ring_ctx_wait_and_kill(), while (ctx->sqo_thread && !wq_has_sleeper(&ctx->sqo_wait)) cpu_relax(); above loop never has an chance to exit, it's because preempt isn't enabled in the kernel, and the context calling io_ring_ctx_wait_and_kill() and io_sq_thread() run in the same cpu, if io_sq_thread calls a cond_resched() yield cpu and another context enters above loop, then io_sq_thread() will always in runqueue and never exit. Use cond_resched() can fix this issue.

2020-04-30io_uring: enable poll retry for any file with ->read_iter / ->write_iterJens Axboe
We can have files like eventfd where it's perfectly fine to do poll based retry on them, right now io_file_supports_async() doesn't take that into account. Pass in data direction and check the f_op instead of just always needing an async worker. Signed-off-by: Jens Axboe <axboe@kernel.dk>
