Now that atomic_check takes the global atomic state as a parameter, we don't need to go through the pointer in the CRTC state. This was done using the following coccinelle script: @ crtc_atomic_func @ identifier helpers; identifier func; @@ static struct drm_crtc_helper_funcs helpers = { ..., .atomic_check = func, ..., }; @@ identifier crtc_atomic_func.func; identifier crtc, state; @@ func(struct drm_crtc *crtc, struct drm_atomic_state *state) { ... - struct drm_crtc_state *crtc_state = drm_atomic_get_new_crtc_state(state, crtc); ... when != crtc_state - crtc_state->state + state ... } @@ struct drm_crtc_state *crtc_state; identifier crtc_atomic_func.func; identifier crtc, state; @@ func(struct drm_crtc *crtc, struct drm_atomic_state *state) { ... - crtc_state->state + state ... } Suggested-by:Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by:

dispnv50 references the crtc->state pointer in order to get the current CRTC state in its atomic_check hook, which would be the old CRTC state in the global atomic state. Use the drm_atomic_get_old_crtc_state helper to get that state to make it more obvious. Suggested-by:

Since commit 9a40401c ("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.

Pull char/misc fixes/removals from Greg KH: "Here's some small fixes for 5.10-rc2 and a big driver removal. 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. But as-is, this codebase didn't work for anyone else so no actual functionality is being removed.

Unless we want to test with THP, then we shouldn't require it to be configured by the host kernel. Unfortunately, even advising with MADV_NOHUGEPAGE does require it, so check for THP first in order to avoid madvise failing with EINVAL. Signed-off-by:

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 671ddc70 ("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). Signed-off-by:

The check for swiotlb has moved to nouveu_ttm.c, but we forgot to move the include as well. This blows up only when merged with linux-next, not sure why drm-misc-next works stand alone. Signed-off-by:

There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2].

Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. Refactor the code according to the use of a flexible-array member in struct gve_stats_report, instead of a zero-length array, and use the struct_size() helper to calculate the size for the resource allocation.
