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's DDC lines to the discrete GPU. This allows us to retrieve the EDID if the panel

...ug in i915 where the SSC status set by BIOS is preserved too late and v1 only contained a workaround, whereas v2 contains a proper fix in a separate commit. The long journey towards retina support: The pixel clock required for retina resolution is not supported by LVDS (which was used on pre-retinas), necessitating eDP instead. Problem is, the gmux register which switches the DDC lines on pre-retinas doesn't switch the AUX channel on retinas. Disassembling the OS X driver revealed that the gmux in retina MBPs gained an additional register 0x7f which gets written to when setting up the eDP...

...aniel 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. On boot the ->probe hook is potentially called dozens of times until it...

All, I have a Solaris 11.1 (x86_64) server using ZFS as the storage facility running samba version 4.1.6. I have several clients that seem to transfer files to and from the server 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

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 DDC lines. Introduce a drm_get_edid_switcheroo() helper which uses this feature.

a. Intel 2.8 Ghz Core I7 (dual core, I7-4558U) in late 2013 Macbook Pro with Retina Display b. I compiled it the same way I compiled 1.2.1: ./configure -enable-static -disable-shared CFLAGS=" -isysroot /Developer/SDKs/MacOSX10.6.sdk -mmacosx-version-min=10.6" make Am i doing something wrong?

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're the active GPU.

Daniel Vetter pointed out that vga_switcheroo_client_probe_defer() could be needed by audio clients as well. To avoid mistakes when someone adds conditions for these in the future, constrain the single existing condition to VGA clients by checking for PCI_BASE_CLASS_DISPLAY. This encompasses both PCI_CLASS_DISPLAY_VGA as well as PCI_CLASS_DISPLAY_3D, which is used by some Nvidia Optimus GPUs. Any

Buenas! Supongo que será fácil, pero se me está haciendo difícil. Tengo un documento Rmarkdown en RStudio en el que escribí lo que me pidieron, que me lo piden en formato MS Word. Markdown lo saca decentemente, pero me temo que no tan decente del todo las imágenes. Quiero que, además de salir las imágenes incrustadas en los respectivos chunks, también salve automáticamente la imágen en archivos a
