Specifically, if we're using systemd-logind the fd remains open when we disable/enable the device, allowing events to queue up on the fd. These events are then replayed once the device is re-opened. This is not the case when VT-switching, in that case logind closes the fd for us.

Though the server has a couple of hacks to route events correctly, mixed devices still experience bugs like [1]. Instead of advertising the device as a single mixed device, split the device into two X devices, one with only a pointer/touch component, one with only a keyboard component. This ensures that the device is effectively attached to both the VCP and the VCK, something the XI2 protocol doesn't really allow. This patch drops the keyboard capability on a mixed device, duplicates the input options and attributes and queues a NewInputDeviceRequest call. The new device only has the keyboard capability but is otherwise unchanged. The wacom driver has used this approach for years. The WorkProc is necessary to avoid inconsistent state, the server doesn't handle a NewInputDeviceRequest during PreInit well. The approach: During pre-init we create a struct xf86libinput_device with the libinput_device and a unique ID. The child device has that ID added to the options and will look for the other device during its pre-init. The two devices then share the xf86libinput_device struct. We only have a single epollfd for all devices and the server calls read_input on the first device in the list with the epollfd as pInfo->fd. That shared struct is used as the userdata on the libinput_device we get back from the event, and each device is in the xorg_list device_list of that shared struct. We loop through those to find the ones with the right capabilities and post the event through that device. Since devices can be enabled and disabled independently, the rest of the code makes sure that we only ever add the device to libinput when the first shared device is enabled, and remove it accordingly. The server uses pInfo->major/minor to detect if another device is using the same path for a logind-controlled fd. If so, it reuses that device's pInfo->fd and sets the "fd" option to that value. That pInfo->fd is the libinput epollfd though, not the actual device fd. This doesn't matter for us, since we manage the fds largely ourselves and the pInfo->fd we use is the epollfd anyway. On unplug however, the udev code triggers a device removal for all devices, including the duplicated ones. When we disable device, we restore the pInfo->fd from the "fd" option so that the server can request logind to close the fd. That only works if the "fd" option is correct, otherwise the server asks logind to close the epollfd and everyone is unhappy.

CARD32 product[2]; int rc; commit 83dfd31ec8ec2596648c33059fffb93b19691fae Author: Peter Hutterer <peter.hutte...@who-t.net> Date: Fri Nov 20 10:51:38 2015 +1000 Revert "Split mixed pointer/keyboard devices into two separate X devices" When using logind, this causes the server to hang when a split device is unplugged. The reason is mostly in the server, when open the device by requesting the logind fd, the server loops through the device list to check if any other device has the same major/minor (see systemd_logind_take_fd()) and returns the pInfo->fd for that device instead of requesting the fd again from logind. For libinput devices, the pInfo->fd is the epollfd, not the actual device, so our second device gets the epollfd assigned. When the devices are removed, we keep the device fd open and release the epollfd through logind. This reverts commit c943739a2bfd4c380db0b21bc35b73deb7496c8a. diff --git a/src/xf86libinput.c b/src/xf86libinput.c index 430fc9a..bc6e677 100644 --- a/src/xf86libinput.c +++ b/src/xf86libinput.c @@ -77,17 +77,9 @@ struct xf86libinput_driver { static struct xf86libinput_driver driver_context; -struct xf86libinput_device { - int refcount; - int enabled_count; - uint32_t id; - struct libinput_device *device; - struct xorg_list device_list; -}; - struct xf86libinput { - InputInfoPtr pInfo; char *path; + struct libinput_device *device; uint32_t capabilities; struct { @@ -130,9 +122,6 @@ struct xf86libinput { } options; struct draglock draglock; - - struct xf86libinput_device *shared_device; - struct xorg_list shared_device_link; }; static inline int @@ -175,112 +164,6 @@ btn_xorg2linux(unsigned int b) return button; } -static inline InputInfoPtr -xf86libinput_get_parent(InputInfoPtr pInfo) -{ - InputInfoPtr parent; - int parent_id; - - parent_id = xf86CheckIntOption(pInfo->options, "_libinput/shared-device", -1); - if (parent_id == -1) - return NULL; - - nt_list_for_each_entry(parent, xf86FirstLocalDevice(), next) { - int id = xf86CheckIntOption(parent->options, - "_libinput/shared-device", - -1); - if (id == parent_id) - return parent; - } - - return NULL; -} - -static inline struct xf86libinput_device* -xf86libinput_shared_create(struct libinput_device *device) -{ - static uint32_t next_shared_device_id; - struct xf86libinput_device *shared_device; - - shared_device = calloc(1, sizeof(*shared_device)); - if (!shared_device) - return NULL; - - shared_device->device = device; - shared_device->refcount = 1; - shared_device->id = ++next_shared_device_id; - xorg_list_init(&shared_device->device_list); - - return shared_device; -} - -static inline struct xf86libinput_device* -xf86libinput_shared_ref(struct xf86libinput_device *shared_device) -{ - shared_device->refcount++;
