drm/nouveau/fbcon: fix font width not divisible by 8

2016-08-22T16:23:24Z

[ Upstream commit 28668f43b8e421634e1623f72a879812288dd06b ] The patch f045f459d925 ("drm/nouveau/fbcon: fix out-of-bounds memory accesses") tries to fix some out of memory accesses. Unfortunatelly, the patch breaks the display when using fonts with width that is not divisiable by 8. The monochrome bitmap for each character is stored in memory by lines from top to bottom. Each line is padded to a full byte. For example, for 22x11 font, each line is padded to 16 bits, so each character is consuming 44 bytes total, that is 11 32-bit words. The patch f045f459d925 changed the logic to "dsize = ALIGN(image->width * image->height, 32) >> 5", that is just 8 words - this is incorrect and it causes display corruption. This patch adds the necesary padding of lines to 8 bytes. This patch should be backported to stable kernels where f045f459d925 was backported.

drm/radeon: Poll for both connect/disconnect on analog connectors

2016-08-22T16:23:05Z

[ Upstream commit 14ff8d48f2235295dfb3117693008e367b49cdb5 ] DRM_CONNECTOR_POLL_CONNECT only enables polling for connections, not disconnections. Because of this, we end up losing hotplug polling for analog connectors once they get connected. Easy way to reproduce: - Grab a machine with a radeon GPU and a VGA port - Plug a monitor into the VGA port, wait for it to update the connector from disconnected to connected - Disconnect the monitor on VGA, a hotplug event is never sent for the removal of the connector. Originally, only using DRM_CONNECTOR_POLL_CONNECT might have been a good idea since doing VGA polling can sometimes result in having to mess with the DAC voltages to figure out whether or not there's actually something there since VGA doesn't have HPD. Doing this would have the potential of showing visible artifacts on the screen every time we ran a poll while a VGA display was connected. Luckily, radeon_vga_detect() only resorts to this sort of polling if the poll is forced, and DRM's polling helper doesn't force it's polls. Additionally, this removes some assignments to connector->polled that weren't actually doing anything.

drm/radeon: add a delay after ATPX dGPU power off

drm/radeon: fix PLL sharing on DCE6.1 (v2)

2016-07-12T12:48:17Z

[ Upstream commit e3c00d87845ab375f90fa6e10a5e72a3a5778cd3 ] On DCE6.1 PPLL2 is exclusively available to UNIPHYA, so it should not be taken into consideration when looking for an already enabled PLL to be shared with other outputs. This fixes the broken VGA port (TRAVIS DP->VGA bridge) on my Richland based laptop, where the internal display is connected to UNIPHYA through a TRAVIS DP->LVDS bridge.
