Jobs on some queues must be provided with a handle to a driver command buffer object, while for other queues, jobs must be provided with an address to a command buffer. Currently the distinction is done based on the queue type, which is less flexible if the same queue type behaves differently on different types of ASICs. This patch adds a new queue property for this target, which is configured per queue type per ASIC type. Signed-off-by:

Commit a753bfcf ("intel_th: Make the switch allocate its subdevices") factored out intel_th_subdevice_alloc() from intel_th_populate(), but got the error path wrong, resulting in two instances of a double put_device() on a freshly initialized, but not 'added' device. Fix this by only doing one put_device() in the error path. Signed-off-by:

On zang's Dell XPS 13 9370 after Thunderbolt NVM firmware upgrade the Thunderbolt controller did not come back as expected. Only after the system was rebooted it became available again. It is not entirely clear what happened but I suspect the new NVM firmware image authentication failed for some reason. Regardless of this the router needs to be power cycled if NVM authentication fails in order to get it fully functional again. This modifies the driver to issue a power cycle in case the NVM authentication fails immediately when dma_port_flash_update_auth() returns. We also need to call tb_switch_set_uuid() earlier to be able to fetch possible NVM authentication failure when DMA port is added. Link: https://bugzilla.kernel.org/show_bug.cgi?id=205457Reported-by:

This change also does a bit of a unification for the IRQ init code. But the actual problem is that UIO_IRQ_NONE == 0, so for the DT case where UIO_IRQ_NONE gets assigned to `uioinfo->irq`, a 2nd initialization will get triggered (for the IRQ) and this one will exit via `goto bad1`. As far as things seem to go, the only case where UIO_IRQ_NONE seems valid, is when using a device-tree. The driver has some legacy support for old platform_data structures. It looks like, for platform_data a non-existent IRQ is an invalid case (or was considered an invalid case). Which is why -ENXIO is treated only when a DT is used. Signed-off-by:

The old loop wouldn't stop when reaching `start` if `start==NULL`, instead continuing backwards to index -1 and crashing. Luckily you need to be highly privileged to map things at NULL, so it's not a big problem. Fix it by adjusting the loop so that the loop variable is always in bounds. This patch is deliberately minimal to simplify backporting, but IMO this function could use a refactor. The jump labels in the second loop body are horrible (the error gotos should be jumping to free_range instead), and both loops would look nicer if they just iterated upwards through indices. And the up_read()+mmput() shouldn't be duplicated like that. Cc: stable@vger.kernel.org Fixes: 457b9a6f ("Staging: android: add binder driver") Signed-off-by:

binder_alloc_mmap_handler() attempts to detect the use of ->mmap() on a binder_proc whose binder_alloc has already been initialized by checking whether alloc->buffer is non-zero. Before commit 88021166 ("binder: remove kernel vm_area for buffer space"), alloc->buffer was a kernel mapping address, which is always non-zero, but since that commit, it is a userspace mapping address. A sufficiently privileged user can map /dev/binder at NULL, tricking binder_alloc_mmap_handler() into assuming that the binder_proc has not been mapped yet. This leads to memory unsafety. Luckily, no context on Android has such privileges, and on a typical Linux desktop system, you need to be root to do that. Fix it by using the mapping size instead of the mapping address to distinguish the mapped case. A valid VMA can't have size zero.

binder_alloc_print_pages() iterates over alloc->pages[0..alloc->buffer_size-1] under alloc->mutex. binder_alloc_mmap_handler() writes alloc->pages and alloc->buffer_size without holding that lock, and even writes them before the last bailout point. Unfortunately we can't take the alloc->mutex in the ->mmap() handler because mmap_sem can be taken while alloc->mutex is held. So instead, we have to locklessly check whether the binder_alloc has been fully initialized with binder_alloc_get_vma(), like in binder_alloc_new_buf_locked().

Usually all the distro will load the parport low level driver as part of their initialization. But we can get into a situation where all the parallel port drivers are built as module and we unload all the modules at a later time. Then if we just do "modprobe parport" it will only load the parport module and will not load the low level driver which will actually register the ports. So, check the bus if there is any parport registered, if not, load the low level driver. We can get into the above situation with all distro but only Suse has setup the alias for "parport_lowlevel" and so it only works in Suse. Users of Debian based distro will need to load the lowlevel module manually. Signed-off-by:
