The pre-retina MacBook Pro uses an LVDS panel and a gmux controller to switch the panel between its two GPUs. The panel mode in VBIOS is notoriously bogus on these machines. Use drm_get_edid_switcheroo() in lieu of drm_get_edid() on LVDS if the vga_switcheroo handler is capable of temporarily switching the panel...

Enable GPU switching on the pre-retina MacBook Pro (2008 - 2013), v5. The main obstacle on these machines is that the panel mode in VBIOS is bogus. Fortunately gmux can switch DDC independently from the display, thereby allowing the inactive GPU to probe the panel's EDID. In short, vga_switcheroo and apple-gmux are amended with ho...

This is a follow-up to the v1 posted in April: http://lists.freedesktop.org/archives/dri-devel/2015-April/081515.html Patches 1 - 17 enable GPU switching on the pre-retina MacBook Pro. These were tested successfully by multiple people and solve two tickets in Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=88861 https://bugs.freedesktop.org/show_bug.cgi?id=61115 Patches 18 - 22 are a preview of how we're tackling retina support. Those are marked experiment...

...9;s coded separately into each of the relevant drivers. As suggested by Daniel Vetter, deduplicate that code in the drivers and move it to a new vga_switcheroo helper. This yields better encapsulation of concepts and lets us add further checks in a central place. (The existing check pertains to pre-retina MacBook Pros and an additional check is expected to be needed for retinas.) One might be tempted to check deferred probing conditions in vga_switcheroo_register_client(), but this is usually called fairly late during driver load. The GPU is fully brought up and ready for switching at that point. O...

...r at acceptable rates (~80 MB/s) read and write. The problem is that I also have several clients that transfer at a very inhibited rate (~1 MB/s). These clients are W7 (x64) both physical machines and virtual. I also have mac clients that exhibit the same slow transfer rate connecting with smb://retina/share and even slower rates when connecting it NT1 protocol (cifs://retina/share). The mac clients are strange in that the performance seems to be asymmetric; transfers from the server are much slower than to the server. I've done testing on a few of these machines to see if the performance w...

The pre-retina MacBook Pro uses an LVDS panel and a gmux controller to switch the panel between its two GPUs. The panel mode in VBIOS is notoriously bogus on these machines and some models have no VBIOS at all, so the inactive GPU cannot set up its LVDS output. Extend vga_switcheroo to support switching only the...

gmux is a microcontroller built into dual GPU MacBook Pros. On pre-retina MBPs, if we're the inactive GPU, we need apple-gmux to temporarily switch DDC so that we can probe the panel's EDID. The checks for CONFIG_VGA_ARB and CONFIG_VGA_SWITCHEROO are necessary because if either of them is disabled but gmux is present, the driver would never load, even if we'...
