2022-03-16drm/gma500: Move GEM memory management functions to gem.cThomas Zimmermann1-4/+1
Move GEM functions from gtt.c to gem.c. Adapt some names. No functional changes.

2022-03-16drm/gma500: Inline psb_gtt_restore()Thomas Zimmermann1-1/+2
Inline psb_gtt_restore() into its only caller in power.c. Perform the GTT restoration in psb_gem_mm_resume(). The restoration step is part of GEM anyway and will be moved over at some point.

2022-03-16drm/gma500: Split GTT init/resume/fini into GTT and GEM functionsThomas Zimmermann1-0/+3
The GTT init, fini and resume functions contain both, GTT and GEM, code. Split each into a separate GTT and a GEM function. The GEM code is responsible for mmap_mutex and the stolen memory area. The rest of the functionality is left in GTT functions.

2022-03-16drm/gma500: Cleanup GTT uninit and error handlingThomas Zimmermann1-1/+1
Replace psb_gtt_takedown() with finalizer function that is only called for unloading the driver. Use roll-back pattern for error handling in psb_gtt_init() and _resume(). Also fixes a bug where vmap_addr was never unmapped.

2022-03-16drm/gma500: Move GTT resume logic out of psb_gtt_init()Thomas Zimmermann1-1/+1

2022-03-16drm/gma500: Remove struct psb_gtt.sem sempahoreThomas Zimmermann1-1/+0
The semaphore at struct psb_mmu_driver.sem protects access to the MMU fields. Additional locking with struct psb_gtt.sem is unnecessary. Remove the field and related code.

2021-10-19drm/gma500: Rename struct gtt_range to struct psb_gem_objectThomas Zimmermann1-15/+0

2021-10-19drm/gma500: Rewrite GTT page insert/remove without struct gtt_rangeThomas Zimmermann1-2/+3
struct gtt_range represents a GEM object and should not be used for GTT setup. Change psb_gtt_insert() and psb_gtt_remove() to receive all necessary parameters from their caller. This also eliminates possible failure from psb_gtt_insert(). There's one exception in psb_gtt_restore(), which requires an upcast from struct resource to struct gtt_range when restoring the GTT after hibernation. A possible solution would track the GEM objects that need restoration separately from the GTT resource. Rename the functions to psb_gtt_insert_pages() and psb_gtt_remove_pages() to reflect their similarity to MMU interfaces. v3: * restore the comments about locking rules (Patrik) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Patrik Jakobsson <patrik.r.jakobsson@gmail.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211015084053.13708-10-tzimmermann@suse.de
2021-10-19drm/gma500: Set page-caching flags in GEM pin/unpinThomas Zimmermann1-1/+1
Caching of the GEM object's backing pages are unrelated to GTT management. Move the respective calls from GTT code to GEM code.

2021-10-19drm/gma500: Inline psb_gtt_{alloc,free}_range() into rsp callersThomas Zimmermann1-0/+6
psb_gtt_alloc_range() allocates struct gtt_range, create the GTT resource and performs some half-baked initialization. Inline the function into its only caller psb_gem_create(). For creating the GTT resource, introduce a new helper, psb_gtt_alloc_resource() that hides the details of the GTT. For psb_gtt_free_range(), inline the function into its only caller psb_gem_free_object(). While at it, remove the explicit invocation of drm_gem_free_mmap_offset(). The mmap offset is already released by drm_gem_object_release(). v3: * replace offset[static 1] with pointer notation (Patrik) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Patrik Jakobsson <patrik.r.jakobsson@gmail.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211015084053.13708-8-tzimmermann@suse.de

2020-11-15drm/gma500: Remove GTT roll supportPatrik Jakobsson1-3/+0
GTT roll support was used to accelerate fb panning on some machines. Unfortunately this never worked properly with multiple monitors and caused issues on others where the framebuffer wouldn't fit in stolen memory. Let's remove it!

2018-05-18drm/gma500: Move GEM BO to drm_framebufferDaniel Stone1-0/+2
Since drm_framebuffer can now store GEM objects directly, place them there rather than in our own subclass. As this makes the framebuffer create_handle and destroy functions the same as the GEM framebuffer helper, we can reuse those.

2011-12-06gma500: gtt based hardware scrolling consoleAlan Cox1-0/+3
Add support for GTT based scrolling. Instead of pushing bits around we simply use the GTT to change the mappings. This provides us with a very fast way to scroll the display providing we have enough memory to allocate on 4K line boundaries. In practice this seems to be the case except for very big displays such as HDMI, and the usual configurations are netbooks/tablets.

2011-11-16gma500: introduce the GTT and MMU handling logicAlan Cox1-0/+61
This fits alongside the GEM support to manage our resources on the card itself. It's not actually clear we need to configure the MMU at all. Further research is needed before removing it entirely. For now we suck it in (slightly abused) from the old semi-free driver. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
