drm/i915/skl: Add support to load SKL CSR firmware. Display Context Save and Restore support is needed for various SKL Display C states like DC5, DC6. This implementation is added based on first version of DMC CSR program that we received from h/w team. Here we are using request_firmware based design. Finally this firmware should end up in linux-firmware tree. For SKL platform its mandatory to ensure that we load this csr program before enabling DC states like DC5/DC6. As CSR program gets reset on various conditions, we should ensure to load it during boot and in future change to be added to load this system resume sequence too. v1: Initial relese as RFC patch v2: Design change as per Daniel, Damien and Shobit's review comments request firmware method followed. v3: Some optimization and functional changes. Pulled register defines into drivers/gpu/drm/i915/i915_reg.h Used kmemdup to allocate and duplicate firmware content. Ensured to free allocated buffer. v4: Modified as per review comments from Satheesh and Daniel Removed temporary buffer. Optimized number of writes by replacing I915_WRITE with I915_WRITE64. v5: Modified as per review comemnts from Damien. - Changed name for functions and firmware. - Introduced HAS_CSR. - Reverted back previous change and used csr_buf with u8 size. - Using cpu_to_be64 for endianness change. Modified as per review comments from Imre. - Modified registers and macro names to be a bit closer to bspec terminology and the existing register naming in the driver. - Early return for non SKL platforms in intel_load_csr_program function. - Added locking around CSR program load function as it may be called concurrently during system/runtime resume. - Releasing the fw before loading the program for consistency - Handled error path during f/w load. v6: Modified as per review comments from Imre. - Corrected out_freecsr sequence. v7: Modified as per review comments from Imre. Fail loading fw if fw->size%8!=0. v8: Rebase to latest. v9: Rebase on top of -nightly (Damien) v10: Enabled support for dmc firmware ver 1.0. According to ver 1.0 in a single binary package all the firmware's that are required for different stepping's of the product will be stored. The package contains the css header, followed by the package header and the actual dmc firmwares. Package header contains the firmware/stepping mapping table and the corresponding firmware offsets to the individual binaries, within the package. Each individual program binary contains the header and the payload sections whose size is specified in the header section. This changes are done to extract the specific firmaware from the package. (Animesh) v11: Modified as per review comemnts from Imre. - Added code comment from bpec for header structure elements. - Added __packed to avoid structure padding. - Added helper functions for stepping and substepping info. - Added code comment for CSR_MAX_FW_SIZE. - Disabled BXT firmware loading, will be enabled with dmc 1.0 support. - Changed skl_stepping_info based on bspec, earlier used from config DB. - Removed duplicate call of cpu_to_be* from intel_csr_load_program function. - Used cpu_to_be32 instead of cpu_to_be64 as firmware binary in dword aligned. - Added sanity check for header length. - Added sanity check for mmio address got from firmware binary. - kmalloc done separately for dmc header and dmc firmware. (Animesh) v12: Modified as per review comemnts from Imre. - Corrected the typo error in skl stepping info structure. - Added out-of-bound access for skl_stepping_info. - Sanity check for mmio address modified. - Sanity check added for stepping and substeppig. - Modified the intel_dmc_info structure, cache only the required header info. (Animesh) v13: clarify firmware load error message. The reason for a firmware loading failure can be obscure if the driver is built-in. Provide an explanation to the user about the likely reason for the failure and how to resolve it. (Imre) v14: Suggested by Jani. - fix s/I915/CONFIG_DRM_I915/ typo - add fw_path to the firmware object instead of using a static ptr (Jani) v15: 1) Changed the firmware name as dmc_gen9.bin, everytime for a new firmware version a symbolic link with same name will help not to build kernel again. 2) Changes done as per review comments from Imre. - Error check removed for intel_csr_ucode_init. - Moved csr-specific data structure to intel_csr.h and optimization done on structure definition. - fw->data used directly for parsing the header info & memory allocation only done separately for payload. (Animesh) v16: - No need for out_regs label in i915_driver_load(), so removed it. - Changed the firmware name as skl_dmc_ver1.bin, followed naming convention <platform>_dmc_<api-version>.bin (Animesh) Issue: VIZ-2569 Signed-off-by: A.Sunil Kamath <sunil.kamath@intel.com> Signed-off-by: Damien Lespiau <damien.lespiau@intel.com> Signed-off-by: Animesh Manna <animesh.manna@intel.com> Signed-off-by: Imre Deak <imre.deak@intel.com> Reviewed-by: Imre Deak <imre.deak@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

drm/i915: Implement a framework for batch buffer pools This adds a small module for managing a pool of batch buffers. The only current use case is for the command parser, as described in the kerneldoc in the patch. The code is simple, but separating it out makes it easier to change the underlying algorithms and to extend to future use cases should they arise. The interface is simple: init to create an empty pool, fini to clean it up, get to obtain a new buffer. Note that all buffers are expected to be inactive before cleaning up the pool. Locking is currently based on the caller holding the struct_mutex. We already do that in the places where we will use the batch pool for the command parser. v2: - s/BUG_ON/WARN_ON/ for locking assertions - Remove the cap on pool size - Switch from alloc/free to init/fini v3: - Idiomatic looping structure in _fini - Correct handling of purged objects - Don't return a buffer that's too much larger than needed v4: - Rebased to latest -nightly v5: - Remove _put() function and clean up comments to match v6: - Move purged check inside the loop (danvet, from v4 1/7 feedback) v7: - Use single list instead of two. (Chris W) - s/active_list/cache_list - Squashed in debug patches (Chris W) drm/i915: Add a batch pool debugfs file It provides some useful information about the buffers in the global command parser batch pool. v2: rebase on global pool instead of per-ring pools v3: rebase drm/i915: Add batch pool details to i915_gem_objects debugfs To better account for the potentially large memory consumption of the batch pool. v8: - Keep cache in LRU order (danvet, from v6 1/5 feedback) Issue: VIZ-4719 Signed-off-by: Brad Volkin <bradley.d.volkin@intel.com> Reviewed-By: Jon Bloomfield <jon.bloomfield@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

drm/i915: preliminary context support Very basic code for context setup/destruction in the driver. Adds the file i915_gem_context.c This file implements HW context support. On gen5+ a HW context consists of an opaque GPU object which is referenced at times of context saves and restores. With RC6 enabled, the context is also referenced as the GPU enters and exists from RC6 (GPU has it's own internal power context, except on gen5). Though something like a context does exist for the media ring, the code only supports contexts for the render ring. In software, there is a distinction between contexts created by the user, and the default HW context. The default HW context is used by GPU clients that do not request setup of their own hardware context. The default context's state is never restored to help prevent programming errors. This would happen if a client ran and piggy-backed off another clients GPU state. The default context only exists to give the GPU some offset to load as the current to invoke a save of the context we actually care about. In fact, the code could likely be constructed, albeit in a more complicated fashion, to never use the default context, though that limits the driver's ability to swap out, and/or destroy other contexts. All other contexts are created as a request by the GPU client. These contexts store GPU state, and thus allow GPU clients to not re-emit state (and potentially query certain state) at any time. The kernel driver makes certain that the appropriate commands are inserted. There are 4 entry points into the contexts, init, fini, open, close. The names are self-explanatory except that init can be called during reset, and also during pm thaw/resume. As we expect our context to be preserved across these events, we do not reinitialize in this case. As Adam Jackson pointed out, The cutoff of 1MB where a HW context is considered too big is arbitrary. The reason for this is even though context sizes are increasing with every generation, they have yet to eclipse even 32k. If we somehow read back way more than that, it probably means BIOS has done something strange, or we're running on a platform that wasn't designed for this. v2: rename load/unload to init/fini (daniel) remove ILK support for get_size() (indirectly daniel) add HAS_HW_CONTEXTS macro to clarify supported platforms (daniel) added comments (Ben) Signed-off-by: Ben Widawsky <ben@bwidawsk.net>

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: Move to atomic plane helpers (v9) Switch plane handling to use the atomic plane helpers. This means that rather than provide our own implementations of .update_plane() and .disable_plane(), we expose the lower-level check/prepare/commit/cleanup entrypoints and let the DRM core implement update/disable for us using those entrypoints. The other main change that falls out of this patch is that our drm_plane's will now always have a valid plane->state that contains the relevant plane state (initial state is allocated at plane creation). The base drm_plane_state pointed to holds the requested source/dest coordinates, and the subclassed intel_plane_state holds the adjusted values that our driver actually uses. v2: - Renamed file from intel_atomic.c to intel_atomic_plane.c (Daniel) - Fix a copy/paste comment mistake (Bob) v3: - Use prepare/cleanup functions that we've already factored out - Use newly refactored pre_commit/commit/post_commit to avoid sleeping during vblank evasion v4: - Rebase to latest di-nightly requires adding an 'old_state' parameter to atomic_update; v5: - Must have botched a rebase somewhere and lost some work. Restore state 'dirty' flag to let begin/end code know which planes to run the pre_commit/post_commit hooks for. This would have actually shown up as broken in the next commit rather than this one. v6: - Squash kerneldoc patch into this one. - Previous patches have now already taken care of most of the infrastructure that used to be in this patch. All we're adding here now is some thin wrappers. v7: - Check return of intel_plane_duplicate_state() for allocation failures. v8: - Drop unused drm_plane_state -> intel_plane_state cast. (Ander) - Squash in actual transition to plane helpers. Significant refactoring earlier in the patchset has made the combined prep+transition much easier to swallow than it was in earlier iterations. (Ander) v9: - s/track_fbs/disabled_planes/ in the atomic crtc flags. The only fb's we need to update frontbuffer tracking for are those on a plane about to be disabled (since the atomic helpers never call prepare_fb() when disabling a plane), so the new name more accurately describes what we're actually tracking.

drm/i915: Introduce a PV INFO page structure for Intel GVT-g. Introduce a PV INFO structure, to facilitate the Intel GVT-g technology, which is a GPU virtualization solution with mediated pass-through. This page contains the shared information between i915 driver and the host emulator. For now, this structure utilizes an area of 4K bytes on HSW GPU's unused MMIO space. Future hardware will have the reserved window architecturally defined, and layout of the page will be added in future BSpec. The i915 driver load routine detects if it is running in a VM by reading the contents of this PV INFO page. Thereafter a flag, vgpu.active is set, and intel_vgpu_active() is used by checking this flag to conclude if GPU is virtualized with Intel GVT-g. By now, intel_vgpu_active() will return true, only when the driver is running as a guest in the Intel GVT-g enhanced environment on HSW platform. v2: take Chris' comments: - call the i915_check_vgpu() in intel_uncore_init() - sanitize i915_check_vgpu() by adding BUILD_BUG_ON() and debug info take Daniel's comments: - put the definition of PV INFO into a new header - i915_vgt_if.h other changes: - access mmio regs by readq/readw in i915_check_vgpu() v3: take Daniel's comments: - move the i915/vgt interfaces into a new i915_vgpu.c - update makefile - add kerneldoc to functions which are non-static - add a DOC: section describing some of the high-level design - update drm docbook other changes: - rename i915_vgt_if.h to i915_vgpu.h v4: take Tvrtko's comments: - fix a typo in commit message - add debug message when vgt version mismatches - rename low_gmadr/high_gmadr to mappable/non-mappable in PV INFO structure Signed-off-by: Yu Zhang <yu.c.zhang@linux.intel.com> Signed-off-by: Jike Song <jike.song@intel.com> Signed-off-by: Eddie Dong <eddie.dong@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
