this function would be used for drm based 2d acceleration driver to get/put dma address through gem handle. when exynos_drm_get_dma_address is called reference count of gem object would be increased not to be released by gem close and when exynos_drm_put_dma_address is called the reference count of this gem object would be decreased to be released.

with this patch, we can allocate physically continuous or non-continuous memory and also it creates scatterlist for iommu support so allocated memory region can be mapped to iommu page table using scatterlist. Signed-off-by:

Later Exynos series from Exynos4X12 support HDMI version 1.4. We will distinguish to use which version via platform data. This patch supports only default features of HDMI version 1.4(The 3D, sound and etc don't support yet) Signed-off-by:

It cannot map correctly if page fault begins from a intermediate address. [The driver prefaults the mapping, so we need to work from the correct base address not the faulting address otherwise the map appears offset by the fault offset] Signed-off-by:

On a system with one HDMI and one VGA connector the latter causes output polling to run every ten seconds. This causes full EDID re-fetch on every poll and approx. 100ms rendering stalls are experienced by full screen page-flipping applications. Optimisation is to trust HPD sense on R600+ ASICs and to skip doing these expensive probes unless HPD sense has changed.

The function radeon_cs_parser_init is only called from two places, in drivers/gpu/drm/radeon/radeon_cs.c and drivers/gpu/drm/radeon/r600_cs.c. In each case, if the call fails another function is called that frees all of the kdata and dpage information in the chunks array. So this information should not be freed in radeon_cs_parser_init as well. Signed-off-by:

This is an initial drm/kms driver for the displaylink devices. Supports fb_defio, supports KMS dumb interface supports 24bpp via conversion to 16bpp, hw can do this better. supports hot unplug using new drm core features. On an unplug, it disables connector polling, unplugs connectors from sysfs, unplugs fbdev layer (using Kay's API), drops all the USB device URBs, and call the drm core to unplug the device. This driver is based in large parts on udlfb.c so I've licensed it under GPLv2. Signed-off-by: -

Two parts to this, one is simple unplug from sysfs for the device node. The second adds an unplugged state, if we have device opens, we just set the unplugged state and return, if we have no device opens we drop the drm device. If after a lastclose we discover we are unplugged we then drop the drm device. v2: use an atomic for unplugged and wrap it for users, add checks on open + mmap + ioctl entry points. Signed-off-by: -

In order to get correct ordering at hot-unplug for userspace, we need to tear down all the sysfs bits at the correct time. This adds a helper to allow drivers to remove the sysfs nodes for all connectors. Signed-off-by: -

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.

Change drm_mode_attachmode_crtc() to take an "all or nothing" approach. If an error is returned, there are no side effects visible. Also change the function to always duplicate the mode passed in. Also change the function to not give up when it finds the first connector without and encoder. A simpler approach would be to just remove the function completely as it's unused currently.
