video/udlfb: fix line counting in fb_write

2012-10-10T02:02:45Z

Line 0 and 1 were both written to line 0 (on the display) and all subsequent lines had an offset of -1. The result was that the last line on the display was never overwritten by writes to /dev/fbN.

mm: kill vma flag VM_RESERVED and mm->reserved_vm counter

2012-10-09T07:22:19Z

A long time ago, in v2.4, VM_RESERVED kept swapout process off VMA, currently it lost original meaning but still has some effects: | effect | alternative flags -+------------------------+--------------------------------------------- 1| account as reserved_vm | VM_IO 2| skip in core dump | VM_IO, VM_DONTDUMP 3| do not merge or expand | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP 4| do not mlock | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP This patch removes reserved_vm counter from mm_struct. Seems like nobody cares about it, it does not exported into userspace directly, it only reduces total_vm showed in proc. Thus VM_RESERVED can be replaced with VM_IO or pair VM_DONTEXPAND | VM_DONTDUMP. remap_pfn_range() and io_remap_pfn_range() set VM_IO|VM_DONTEXPAND|VM_DONTDUMP. remap_vmalloc_range() set VM_DONTEXPAND | VM_DONTDUMP.

fb_defio: add first_io callback

2012-04-29T19:35:31Z

With this optional callback the driver is notified when the first page is entered into the pagelist and a new deferred_io call is scheduled. A possible use-case for this is runtime-pm. In the first_io call pm_runtime_get() could be called, which starts an asynchronous runtime_resume of the device. In the deferred_io callback a call to pm_runtime_barrier() makes the sure, the device is resumed by then and a pm_runtime_put() may put the device back to sleep. Also, some SoCs may use the runtime-pm system to determine if they are able to enter deeper idle states. Therefore it is necessary to keep the use-count from the first written page until the conclusion of the screen update, to prevent the system from going to sleep before completing the pending update. Two users of defio were using kmalloc to allocate the structure. These allocations are changed to kzalloc, to prevent uninitialised .first_io members in those drivers.

USB: udlfb.c: remove err() usage

2012-04-25T19:37:49Z

err() was a very old USB-specific macro that I thought had gone away. This patch removes it from being used in the driver and uses dev_err() instead. CC: Bernie Thompson CC: Florian Tobias Schandinat Signed-off-by: Greg Kroah-Hartman

udlfb: remove sysfs framebuffer device with USB .disconnect()

2012-03-15T13:35:22Z

The USB graphics card driver delays the unregistering of the framebuffer device to a workqueue, which breaks the userspace visible remove uevent sequence. Recent userspace tools started to support USB graphics card hotplug out-of-the-box and rely on proper events sent by the kernel. The framebuffer device is a direct child of the USB interface which is removed immediately after the USB .disconnect() callback. But the fb device in /sys stays around until its final cleanup, at a time where all the parent devices have been removed already. To work around that, we remove the sysfs fb device directly in the USB .disconnect() callback and leave only the cleanup of the internal fb data to the delayed work. Before: add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb) add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb) add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/graphics/fb0 (graphics) remove /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb) remove /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb) remove /2-1.2:1.0/graphics/fb0 (graphics) After: add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb) add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb) add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/graphics/fb1 (graphics) remove /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/graphics/fb1 (graphics) remove /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb) remove /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb) Cc: stable@vger.kernel.org Tested-by: Bernie Thompson Acked-by: Bernie Thompson Signed-off-by: Kay Sievers Signed-off-by: Florian Tobias Schandinat

Some user scenarios need to prioritize performance over maxiumum resolution. Also, some devices may have bad vendor descriptors, and this allows the user to set a pixel limit that matches their specific device to avoid blank screens on higher resolution monitors. 700000 minimum for DL-115, 2360000 maximum for DL-195 Signed-off-by: Ben Collins Signed-off-by: Bernie Thompson
