2020-11-05drm/kmb: Add support for KeemBay DisplayAnitha Chrisanthus5-0/+1493
This is a basic KMS atomic modesetting display driver for KeemBay family of SOCs. Driver has no 2D or 3D graphics. It calls into the ADV bridge driver at the connector level. Single CRTC with LCD controller->mipi DSI->ADV bridge Only 1080p resolution and single plane is supported at this time. v2: moved extern to .h, removed license text use drm_dev_init, upclassed dev_private, removed HAVE_IRQ.(Sam) v3: Squashed all 59 commits to one v4: review changes from Sam Ravnborg renamed dev_p to kmb moved clocks under kmb_clock, consolidated clk initializations use drmm functions use DRM_GEM_CMA_DRIVER_OPS_VMAP v5: corrected spellings v6: corrected checkpatch warnings v7: review changes Sam Ravnborg and Thomas Zimmerman removed kmb_crtc.h kmb_crtc_cleanup (Thomas) renamed mode_set, kmb_load, inlined unload (Thomas) moved remaining logging to drm_*(Thomas) re-orged driver initialization (Thomas) moved plane_status to drm_private (Sam) removed unnecessary logs and defines and ifdef codes (Sam) call helper_check in plane_atomic_check (Sam) renamed set to get for bpp and format functions(Sam) use drm helper functions for reset, duplicate/destroy state instead of kmb functions (Sam) removed kmb_priv from kmb_plane and removed kmb_plane_state (Sam) v8: get clk_pll0 from display node in dt v9: moved csc_coef_lcd to plane.c (Daniel Vetter) call drm_atomic_helper_shutdown in remove (Daniel V) use drm_crtc_handle_vblank (Daniel V) renamed kmb_dsi_hw_init to kmb_dsi_mode_set (Daniel V) complimentary changes to device tree changes (Rob) v10: call drm_crtc_arm_vblank_event in atomic_flush (Daniel V) moved global vars to kmb_private and added locks (Daniel V) changes in driver to accommodate changes in DT to separate DSI entries (Sam R) review changes to separate mipi DSI (Sam R) v11: review changes to separate msscam (Neil A,Sam R) v12: fixed warnings Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Anitha Chrisanthus <anitha.chrisanthus@intel.com> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Cc: Sam Ravnborg <sam@ravnborg.org> Cc: Thomas Zimmermann <tzimmermann@suse.de> Cc: Daniel Vetter <daniel@ffwll.ch> Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/1604538931-26726-6-git-send-email-anitha.chrisanthus@intel.com

2020-11-02drm: Remove SCATTERLIST_MAX_SEGMENTJason Gunthorpe5-12/+5
Since commit 9a40401cfa13 ("lib/scatterlist: Do not limit max_segment to PAGE_ALIGNED values") the max_segment input to sg_alloc_table_from_pages() does not have to be any special value. The new algorithm will always create something less than what the user provides. Thus eliminate this confusing constant. - vmwgfx should use the HW capability, not mix in the OS page size for calling dma_set_max_seg_size() - i915 uses i915_sg_segment_size() both for sg_alloc_table_from_pages and for some open coded sgl construction. This doesn't change the value since rounddown(size, UINT_MAX) == SCATTERLIST_MAX_SEGMENT - drm_prime_pages_to_sg uses it as a default if max_segment is zero, UINT_MAX is fine to use directly.

It seems that a recent commit broke the nouveau compilation when swiotlb is disabled (which is the case on our ARM defconfig for example). Daniel says """ Since the proper fix is maybe stuck in the usual "drm abuses swiotlb internals" bikeshed, maybe best if we push a fix to including limits.h in nouveau and call it done? """ So let's go down the simplest path to fix our build, and goes back to it later if needed.

The fixes are for some reported issues in the interconnect and coresight drivers, nothing major. The "big" driver removal is the MIC drivers have been asked to be removed as the hardware never shipped and Intel no longer wants to maintain something that no one can use. This is welcomed by many as the DMA usage of these drivers was "interesting" and the security people were starting to question some issues that were starting to be found in the codebase. Note, one of the subsystems for this driver, the "VOP" code, will probably come back in future kernel versions as it was looking to potentially solve some PCIe virtualization issues that a number of other vendors were wanting to solve.

It was noticed that evmcs_sanitize_exec_ctrls() is not being executed nowadays despite the code checking 'enable_evmcs' static key looking correct. Turns out, static key magic doesn't work in '__init' section (and it is unclear when things changed) but setup_vmcs_config() is called only once per CPU so we don't really need it to. Switch to checking 'enlightened_vmcs' instead, it is supposed to be in sync with 'enable_evmcs'. Opportunistically make evmcs_sanitize_exec_ctrls '__init' and drop unneeded extra newline from it.

Add a regression test for commit 671ddc700fd0 ("KVM: nVMX: Don't leak L1 MMIO regions to L2"). First, check to see that an L2 guest can be launched with a valid APIC-access address that is backed by a page of L1 physical memory. Next, set the APIC-access address to a (valid) L1 physical address that is not backed by memory. KVM can't handle this situation, so resuming L2 should result in a KVM exit for internal error (emulation).
