drm/i915: Kconfig option to disable the legacy fbdev support Boots Just Fine (tm)! The only glitch seems to be that at least on Fedora the boot splash gets confused and doesn't display much at all. And since there's no ugly console flickering anymore in between, the flicker while switching between X servers (VT support is still enabled) is even more jarring. Also, I'm unsure whether we don't need to somehow kick out vgacon, now that nothing else gets in the way. But stuff seems to work, so I don't care. Also everything still works as well with VGA_CONSOLE=n Also the #ifdef mess needs a bit of a cleanup, follow-up patches will do just that. To keep the Kconfig tidy, extract all the i915 options into its own file. v2: - Rebase on top of the preliminary hw support option and the intel_drv.h cleanup. - Shut up warnings in i915_debugfs.c v3: Use the right CONFIG variable, spotted by Chon Ming.

drm/i915: Make AGP support optional We only depend on the intel-gtt module for GTT frobbign on older gens. The intel_agp module is optional, except for UMS and some old XvMC userland on gen3. So make AGP support optional. As before, we will fail the i915 init for UMS and gen3 KMS the same as before if intel_agp isn't around. intel-gtt.c is left with a somewhat ugly ifdef mess, but I'm going to save that for a later cleaning. At least my gen2 still works with the patch and CONFIG_AGP=n. v2: Make i915 depend on X86 and PCI, and intel-gtt depend on PCI Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

drm/i915: Introduce mapping of user pages into video memory (userptr) ioctl By exporting the ability to map user address and inserting PTEs representing their backing pages into the GTT, we can exploit UMA in order to utilize normal application data as a texture source or even as a render target (depending upon the capabilities of the chipset). This has a number of uses, with zero-copy downloads to the GPU and efficient readback making the intermixed streaming of CPU and GPU operations fairly efficient. This ability has many widespread implications from faster rendering of client-side software rasterisers (chromium), mitigation of stalls due to read back (firefox) and to faster pipelining of texture data (such as pixel buffer objects in GL or data blobs in CL). v2: Compile with CONFIG_MMU_NOTIFIER v3: We can sleep while performing invalidate-range, which we can utilise to drop our page references prior to the kernel manipulating the vma (for either discard or cloning) and so protect normal users. v4: Only run the invalidate notifier if the range intercepts the bo. v5: Prevent userspace from attempting to GTT mmap non-page aligned buffers v6: Recheck after reacquire mutex for lost mmu. v7: Fix implicit padding of ioctl struct by rounding to next 64bit boundary. v8: Fix rebasing error after forwarding porting the back port. v9: Limit the userptr to page aligned entries. We now expect userspace to handle all the offset-in-page adjustments itself. v10: Prevent vma from being copied across fork to avoid issues with cow. v11: Drop vma behaviour changes -- locking is nigh on impossible. Use a worker to load user pages to avoid lock inversions. v12: Use get_task_mm()/mmput() for correct refcounting of mm. v13: Use a worker to release the mmu_notifier to avoid lock inversion v14: Decouple mmu_notifier from struct_mutex using a custom mmu_notifer with its own locking and tree of objects for each mm/mmu_notifier. v15: Prevent overlapping userptr objects, and invalidate all objects within the mmu_notifier range v16: Fix a typo for iterating over multiple objects in the range and rearrange error path to destroy the mmu_notifier locklessly. Also close a race between invalidate_range and the get_pages_worker. v17: Close a race between get_pages_worker/invalidate_range and fresh allocations of the same userptr range - and notice that struct_mutex was presumed to be held when during creation it wasn't. v18: Sigh. Fix the refactor of st_set_pages() to allocate enough memory for the struct sg_table and to clear it before reporting an error. v19: Always error out on read-only userptr requests as we don't have the hardware infrastructure to support them at the moment. v20: Refuse to implement read-only support until we have the required infrastructure - but reserve the bit in flags for future use. v21: use_mm() is not required for get_user_pages(). It is only meant to be used to fix up the kernel thread's current->mm for use with copy_user(). v22: Use sg_alloc_table_from_pages for that chunky feeling v23: Export a function for sanity checking dma-buf rather than encode userptr details elsewhere, and clean up comments based on suggestions by Bradley.

drm/i915/dsi: switch to drm_panel interface Replace intel_dsi_device and intel_dsi_dev_ops with drm_panel and drm_panel_funcs. They are adequate for what we have now, and if we end up needing more than this we should improve drm_panel. This will keep us better aligned with the drm core infrastructure. The panel driver initialization changes a bit.

drm/i915/dsi: add drm mipi dsi host support Add basic support for using the drm mipi dsi framework for DSI. We don't use device tree which is pretty much required by mipi_dsi_host_register and friends, and we don't have the kind of device model the functions expect either. So we cheat and use it as a library to abstract what we need: a nice, clean interface for DSI transfers. This means we will have to be careful with what functions we call, as the driver model devices in mipi_dsi_host and mipi_dsi_device will *not* be initialized.

Choose this option if you have a system that has "Intel Graphics
Media Accelerator" or "HD Graphics" integrated graphics,
including 830M, 845G, 852GM, 855GM, 865G, 915G, 945G, 965G,
G35, G41, G43, G45 chipsets and Celeron, Pentium, Core i3,
Core i5, Core i7 as well as Atom CPUs with integrated graphics.
If M is selected, the module will be called i915. AGP support
is required for this driver to work. This driver is used by
the Intel driver in X.org 6.8 and XFree86 4.4 and above. It
replaces the older i830 module that supported a subset of the
hardware in older X.org releases.
Note that the older i810/i815 chipsets require the use of the
i810 driver instead, and the Atom z5xx series has an entirely
different implementation.

drm/i915: Deprecated UMS support It's been 5 years since kms support was merged and roughly 4 years since UMS support was ripped out from userspace drivers. Thus far it's not been a big burden to keep the ums paths alive, and we've made some good progress in better separating it from the kms code by sprinkling DRIVER_MODESET checks all over the place. But now that the drm demidlayering is within reach this changes. I want to make the driver loading code more robust using devres.c and other cool tricks. But that doesn't work with ums due to the shadow-attach trick. Which means we either a) need to split out a complete ums codebase like radeon has b) kill it for good. The 2nd option is obviously much less work than the first, so I think it's time to test the waters and see how many people out there still use ums. I've decided that silently failing to initialize the driver (and not e.g. failing to load the module) is the right thing. That way we should only get reports from users that actually care about some ums features (like accelerated gl or support for secondary outputs). Everyone else will just fall back to the vesa X driver. For developers there's a small info level dmesg output. The plan is to drop this Kconfig option after 3.16 (so gives us 2 full releases) and then start killing code for real 2-3 releases afterwards. That should be more than enough time for users to pipe up. Of course if anyone does we need to revisit this plan and maybe go with option a) above. Also enable the KMS support by default in Kconfig and polish the help texts a bit. v2: Add the missing hunk of actual code changes. Oops.
