[PATCH v2 1/4] drm/xe/vm: Validate userptr during gpu vma prefetching

by Thomas Hellström

If a userptr vma subject to prefetching was already invalidated or invalidated during the prefetch operation, the operation would repeatedly return -EAGAIN which would typically cause an infinite loop. Validate the userptr to ensure this doesn't happen. v2: - Don't fallthrough from UNMAP to PREFETCH (Matthew Brost) Fixes: 5bd24e78829a ("drm/xe/vm: Subclass userptr vmas") Fixes: 617eebb9c480 ("drm/xe: Fix array of binds") Cc: Matthew Brost <matthew.brost(a)intel.com> Cc: <stable(a)vger.kernel.org> # v6.9+ Suggested-by: Matthew Brost <matthew.brost(a)intel.com> Signed-off-by: Thomas Hellström <thomas.hellstrom(a)linux.intel.com> --- drivers/gpu/drm/xe/xe_vm.c | 11 ++++++++++- 1 file changed, 10 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/xe/xe_vm.c b/drivers/gpu/drm/xe/xe_vm.c index 996000f2424e..6fdc17be619e 100644 --- a/drivers/gpu/drm/xe/xe_vm.c +++ b/drivers/gpu/drm/xe/xe_vm.c @@ -2306,8 +2306,17 @@ static int vm_bind_ioctl_ops_parse(struct xe_vm *vm, struct drm_gpuva_ops *ops, break; } case DRM_GPUVA_OP_UNMAP: + xe_vma_ops_incr_pt_update_ops(vops, op->tile_mask); + break; case DRM_GPUVA_OP_PREFETCH: - /* FIXME: Need to skip some prefetch ops */ + vma = gpuva_to_vma(op->base.prefetch.va); + + if (xe_vma_is_userptr(vma)) { + err = xe_vma_userptr_pin_pages(to_userptr_vma(vma)); + if (err) + return err; + } + xe_vma_ops_incr_pt_update_ops(vops, op->tile_mask); break; default: -- 2.48.1

[PATCH] spi: microchip-core: prevent RX overflows when transmit size > FIFO size

by Conor Dooley

From: Conor Dooley <conor.dooley(a)microchip.com> When the size of a transfer exceeds the size of the FIFO (32 bytes), RX overflows will be generated and receive data will be corrupted and warnings will be produced. For example, here's an error generated by a transfer of 36 bytes: spi_master spi0: mchp_corespi_interrupt: RX OVERFLOW: rxlen: 4, txlen: 0 I am not entirely sure how this happens, as rxlen being 4 means that 32 of 36 bytes have been read from the RX FIFO so there should be sufficient room for 4 more bytes but timing is likely a factor as simply adding a delay in the transmit path is enough to avoid the overflows.

[PATCH 2/3] drm/xe/hmm: Don't dereference struct page pointers without notifier lock

by Thomas Hellström

The pnfs that we obtain from hmm_range_fault() point to pages that we don't have a reference on, and the guarantee that they are still in the cpu page-tables is that the notifier lock must be held and the notifier seqno is still valid. So while building the sg table and marking the pages accesses / dirty we need to hold this lock with a validated seqno. However, the lock is reclaim tainted which makes sg_alloc_table_from_pages_segment() unusable, since it internally allocates memory. Instead build the sg-table manually. For the non-iommu case this might lead to fewer coalesces, but if that's a problem it can be fixed up later in the resource cursor code. For the iommu case, the whole sg-table may still be coalesced to a single contigous device va region. This avoids marking pages that we don't own dirty and accessed, and it also avoid dereferencing struct pages that we don't own.

[PATCH v8] arm64: mm: Populate vmemmap at the page level if not section aligned

by Zhenhua Huang

On the arm64 platform with 4K base page config, SECTION_SIZE_BITS is set to 27, making one section 128M. The related page struct which vmemmap points to is 2M then. Commit c1cc1552616d ("arm64: MMU initialisation") optimizes the vmemmap to populate at the PMD section level which was suitable initially since hot plug granule is always one section(128M). However, commit ba72b4c8cf60 ("mm/sparsemem: support sub-section hotplug") introduced a 2M(SUBSECTION_SIZE) hot plug granule, which disrupted the existing arm64 assumptions. The first problem is that if start or end is not aligned to a section boundary, such as when a subsection is hot added, populating the entire section is wasteful. The next problem is if we hotplug something that spans part of 128 MiB section (subsections, let's call it memblock1), and then hotplug something that spans another part of a 128 MiB section(subsections, let's call it memblock2), and subsequently unplug memblock1, vmemmap_free() will clear the entire PMD entry which also supports memblock2 even though memblock2 is still active. Assuming hotplug/unplug sizes are guaranteed to be symmetric. Do the fix similar to x86-64: populate to pages levels if start/end is not aligned with section boundary.

[PATCH] usb: dwc3: Set SUSPENDENABLE soon after phy init

by Thinh Nguyen

After phy initialization, some phy operations can only be executed while in lower P states. Ensure GUSB3PIPECTL.SUSPENDENABLE and GUSB2PHYCFG.SUSPHY are set soon after initialization to avoid blocking phy ops. Previously the SUSPENDENABLE bits are only set after the controller initialization, which may not happen right away if there's no gadget driver or xhci driver bound. Revise this to clear SUSPENDENABLE bits only when there's mode switching (change in GCTL.PRTCAPDIR).
