Embedding the node in the obj is more natural in the transition to VMAs which will also have embedded nodes. This change also helps transition away from put_block to remove node. Though it's quite an uncommon occurrence, it's somewhat convenient to not fail at bind time because we cannot allocate the node. Though in practice there are other allocations (like the request structure) which would probably make this point not terribly useful. Quoting Daniel: Note that the only difference between put_block and remove_node is that the former fills up the preallocation cache. Which we don't need anyway and hence is just wasted space. v2: Clean up the stolen preallocation code. Rebased on the reserve_node patches renames ggtt_ stuff to gtt_ stuff WARN_ON if the object is already bound (which doesn't mean it's in the bound list, tricky) Signed-off-by: NBen Widawsky <ben@bwidawsk.net> Signed-off-by: NDaniel Vetter <daniel.vetter@ffwll.ch>

With the getters in place from the previous patch this members serves no purpose other than saving one spare pointer chase, which will be killed in the next patch anyway. Moving to VMAs, this members adds unnecessary confusion since an object may exist at different offsets in different VMs. v2: Properly preserve the stolen offset. This code is a bit hacky but it all goes away when we embed the drm_mm_node and removes the need for the incorrect patch I submitted previously: "Use gtt_space->start for stolen reservation" Signed-off-by: NBen Widawsky <ben@bwidawsk.net> Signed-off-by: NDaniel Vetter <daniel.vetter@ffwll.ch>

Soon we want to gut a lot of our existing assumptions how many address spaces an object can live in, and in doing so, embed the drm_mm_node in the object (and later the VMA). It's possible in the future we'll want to add more getter/setter methods, but for now this is enough to enable the VMAs. v2: Reworked commit message (Ben) Added comments to the main functions (Ben) sed -i "s/i915_gem_obj_set_color/i915_gem_obj_ggtt_set_color/" drivers/gpu/drm/i915/*.[ch] sed -i "s/i915_gem_obj_bound/i915_gem_obj_ggtt_bound/" drivers/gpu/drm/i915/*.[ch] sed -i "s/i915_gem_obj_size/i915_gem_obj_ggtt_size/" drivers/gpu/drm/i915/*.[ch] sed -i "s/i915_gem_obj_offset/i915_gem_obj_ggtt_offset/" drivers/gpu/drm/i915/*.[ch] (Daniel) v3: Rebased on new reserve_node patch Changed DRM_DEBUG_KMS to actually work (will need fixing later) Signed-off-by: NBen Widawsky <ben@bwidawsk.net> Signed-off-by: NDaniel Vetter <daniel.vetter@ffwll.ch>

With the previous patch we no longer actually create a node, we simply find the correct hole and occupy it. This very well could have been squashed with the last patch, but since I already had David's review, I figured it's easiest to keep it distinct. Also update the users in i915.

For an upcoming patch where we introduce the i915 VMA, it's ideal to have the drm_mm_node as part of the VMA struct (ie. it's pre-allocated). Part of the conversion to VMAs is to kill off obj->gtt_space. Doing this will break a bunch of code, but amongst them are 2 callers of drm_mm_create_block(), both related to stolen memory. It also allows us to embed the drm_mm_node into the object currently which provides a nice transition over to the new code. v2: Reordered to do before ripping out obj->gtt_offset.

Use wait_for() instead of the open coded loop to avoid spreading the same old timeout related bugs. This changes the loop to use msleep(1) instead of udelay(10) when the Punit had not yet completed the frequency change.

Nothing outside of i915_gem_gtt.c and more specifically, the relevant gen specific init function should need to know about number of PDEs, or PTEs per PD. Exposing this will only lead to circumventing using the upcoming VM abstraction.

Lots of bangin my head against the wall^UExperiments have shown that we really need to enable the lvds port before we enable plls. Strangely that seems to include the fdi rx pll on the pch.

It's been splattered over 3 different places all doing random things. Now we have (mostly) the same sequence as i8xx/i9xx, but all called from the crtc_enable hook (through the pll->enable function): - write new dividers - enable vco and wait for stable clocks - write again for the pixel mutliplier I've left the seemingly random 200 usec delay in there, just in case. Also move the encoder->pre_pll_enable hook into the crtc_enable function, at the same spot we currently have a hack to enable the lvds port. Since that hack is now redundant, kill it. While doing this patch I've learned the hard way that we can only fire up the LVDS port if both the pch dpll _and_ the fdi rc pll are not yet enabled. Otherwise things go haywire, at least on cpt. v2: It is paramount to write the FPx divisors before we enable the the vco by writing to the DPLL registers, for otherwise the divisors won't get updated. This is in line with the i8xx/i9xx dpll. v3: To keep the nice abstraction add a ->mode_set callback to set the divisors. Also streamline the enabling/disabling code a bit by removing some cargo-cult duplication and clearing registers where possible in the ->disable hook. v4: Remove now unused local variable.
