HID: hyperv: Use in-place iterator API in the channel callback

2019-11-06T12:05:46+00:00

[ Upstream commit 6a297c90efa68b2864483193b8bfb0d19478600c ] Simplify the ring buffer handling with the in-place API. Also avoid the dynamic allocation and the memory leak in the channel callback function. Signed-off-by: Dexuan Cui Acked-by: Jiri Kosina Signed-off-by: Sasha Levin

Input: hyper-v - fix wakeup from suspend-to-idle

2018-12-21T13:15:12+00:00

[ Upstream commit 10f91c73cc41ceead210a905dbd196398e99c7d2 ] It makes little sense but still possible to put Hyper-V guests into suspend-to-idle state. To wake them up two wakeup sources were registered in the past: hyperv-keyboard and hid-hyperv. However, since commit eed4d47efe95 ("ACPI / sleep: Ignore spurious SCI wakeups from suspend-to-idle") pm_wakeup_event() from these devices is ignored. Switch to pm_wakeup_hard_event() API as these devices are actually the only possible way to wakeup Hyper-V guests.

use the new async probing feature for the hyperv drivers

2018-07-03T11:02:28+00:00

Recent kernels support asynchronous probing; most hyperv drivers can be probed async easily so set the required flag for this. Signed-off-by: Arjan van de Ven Signed-off-by: Stephen Hemminger Signed-off-by: K. Y. Srinivasan Signed-off-by: Greg Kroah-Hartman

HID: hyperv: pr_err() strings should end with newlines

2017-10-05T09:27:08+00:00

pr_err() messages should terminated with a new-line to avoid other messages being concatenated onto the end. Signed-off-by: Arvind Yadav Signed-off-by: Jiri Kosina

HID: hyperv: match wait_for_completion_timeout return type

2015-01-26T13:25:41+00:00

The return type of wait_for_completion_timeout is unsigned long not int. This patch fixes up the declarations only. Patch was compile tested only for x86_64_defconfig + CONFIG_X86_VSMP=y CONFIG_HYPERV=m, CONFIG_HID_HYPERV_MOUSE=m Signed-off-by: Nicholas Mc Guire Signed-off-by: K. Y.

HID: hyperv: register as a wakeup source

2014-08-04T09:20:20+00:00

With this patch, we can move the mouse to wake up the VM after the VM executes "echo freeze > /sys/power/state". This addresses part of https://bugzilla.redhat.com/show_bug.cgi?id=1086100 Signed-off-by: Dexuan Cui Signed-off-by: K. Y. Srinivasan Signed-off-by: Jiri Kosina

HID: hyperv: fix _raw_request() prototype

2014-03-29T01:40:42+00:00

The 3rd argument is pointer to the buffer, not a single __u8. This has no bad sideeffect, as the stub is not using any of its argument, but better have it correct. Signed-off-by: Jiri Kosina

HID: hyperv: Implement a stub raw_request() entry point

2014-03-29T01:35:02+00:00

commit 3c86726cfe38 ("HID: make .raw_request mandatory") made .raw_request mandatory and broke the Hyper-V mouse driver. This patch fixes the problem. Signed-off-by: K. Y. Srinivasan Reviewed-by: Benjamin Tissoires Signed-off-by: Jiri Kosina

HID: hyperv: make sure input buffer is big enough

2014-02-17T20:18:35+00:00

We need at least HID_MAX_BUFFER_SIZE (4096) bytes as input buffer. HID core depends on this as it requires every input report to be at least as big as advertised. Signed-off-by: David Herrmann Signed-off-by: K. Y. Srinivasan Signed-off-by: Jiri Kosina
