| | | | | | | | | | On IGP if you pass option agpmode=-1 you would overwrite the set_page function callback with improper function which endup in non functioning hw.

* drm/radeon/kms: fix LVDS setup on r4xxAlex Deucher2009-12-023-4/+11
| | | | | | | | | | | | | R4xx mobility chips use atombios, which does not store the LVDS_GEN_CNTL parameter setup like combios. Rather, it's configured in LVDSEncoderControl. As such, LVDS_GEN_CNTL is set wrong when on resume. Call LVDSEncoderControl to set it properly.

* drm/radeon/kms: deal with connectors sourced to the same encoderAlex Deucher2009-12-021-0/+33
| | | | | | | | | | | | | | | Some systems have multiple connectors connected to the same encoder; e.g., DVI and HDMI connected to the same encoder with the same ddc line. Since we expose connectors as xrandr outputs, randr treats them separately which results in it trying to source the same encoder to different crtcs. If we have an HDMI and DVI-D port on the same encoder, pick the one to be considered connected based on the edid (HDMI if edid indicates HDMI, DVI otherwise).

| | | | | | | | | | | | | | | | Keep requested scaler type in radeon_encoder and the actual scaler type used in radeon_crtc. This prevents us from enabling the scaler when it's not required (i.e., the requested mode is the native mode). Also, always set the adjusted mode equal to the native mode for lvds.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the framebuffer driver does not publish detailed timing information for the current video mode, the correct value for the pixclock field is zero, not -1. Since pixclock is actually unsigned, the value -1 would be interpreted as 4294967295 picoseconds (i.e., about 4 milliseconds) by register_framebuffer() and userspace programs.

* | drm: make sure page protections are updated after changing vm_flagsJeremy Fitzhardinge2009-11-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some architectures compute ->vm_page_prot depending on ->vm_flags, so we need to update the protections after adjusting the flags. AFAIK this only affects running X under Xen; without this patch you get lots of coloured blobs on the screen, or maybe a complete lockup. Or anything really. But that still depends on lots of out-of-tree stuff, so I don't think there are any consequences for anyone else. But it is wrong in principle.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | unused_nodes modification needs to be protected by unused_lock spinlock. Here is an example of an usage where there is no such protection without this patch. Process 1: 1-drm_mm_pre_get(this function modify unused_nodes list) 2-spin_lock(spinlock protecting mm struct) 3-drm_mm_put_block(this function might modify unused_nodes list but doesn't protect modification with unused_lock) 4-spin_unlock(spinlock protecting mm struct) Process2: 1-drm_mm_pre_get(this function modify unused_nodes list) At this point Process1 & Process2 might both be doing modification to unused_nodes list.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes RH bugzilla #527874. On resume the atom posting wasn't working, however vbe posting was going fine, after 2 weeks over irc, and 8 hrs with the hardware, I tracked it down to the memory device table and it access the MC registers via IIO, it appears the rv515 atom iio table might not be fully functional, so adding a readback before doing a write either provides enough delay to make things resume correctly.
