A channel in Hyper-V is equivalent to a device. Thus, a channel is persistent once it is presented to the guest, even if the driver managing this device is unloaded. By checking and invoking the driver specific callback function under the protection of the channel inbound_lock, we can properly deal with racing driver unloads since an unloading driver sets the callback to NULL under the protection of this inbound_lock.

The Windows team has informed us that on Windows guests on Hyper-V, they check for events before messages. They also recommended that we do the same. This patch addresses this. Signed-off-by:

If any memory allocation failed, goto alloc_status_switch leads to mutex_unlock(&context->ctx_lock) while context is NULL. The patch moves alloc_status_switch to handle error conditions in correct way. Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by:

If kzalloc failed for allocation of context, goto alloc_status_switch leads to unlock of unacquired driver_lock. The patch moves mutex_lock(&driver_lock) before allocation of context. Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by:

According to the comment, the default mode should be 800x600x8 while the index points actually to 800x600x16. Change the comment and move the definition instead of changing the current behaviour. Signed-off-by:

The code for determining the default video mode is unnecessarily duplicated in XGIfb_search_mode() and XGIfb_search_vesamode() functions. Signed-off-by:

The same default video mode should be assumed regardless if the driver is a module or not. This won't change the current behaviour, but it will simplify further changes. Signed-off-by:

Aaro Koskinen authored
When searching the video mode, some HW details needs to be known. Therefore it's not possible to do that reliably before probe(). Signed-off-by:
-
Aaro Koskinen authored
If the driver fails to get LVDS LCD data from the firmware, it falls back to using driver's hardcoded values. However, this is done too early in the probe. The selected video mode index is not yet known, and also in some cases it could be defaulting to -1 resulting in a read outside the array. Fix this by moving the array lookup after the video mode validation. Signed-off-by:
