Thanks, Sasha ------------------ original commit in Linus's tree ------------------ From 71ce046327cfd3aef3f93d1c44e091395eb03f8f Mon Sep 17 00:00:00 2001 From: Zack Rusin <zack.rusin(a)broadcom.com> Date: Fri, 5 Jan 2024 08:51:05 -0500 Subject: [PATCH] drm/ttm: Make sure the mapped tt pages are decrypted when needed MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Some drivers require the mapped tt pages to be decrypted. In an ideal world this would have been handled by the dma layer, but the TTM page fault handling would have to be rewritten to able to do that. A side-effect of the TTM page fault handling is using a dma allocation per order (via ttm_pool_alloc_page) which makes it impossible to just trivially use dma_mmap_attrs. As a result ttm has to be very careful about trying to make its pgprot for the mapped tt pages match what the dma layer thinks it is. At the ttm layer it's possible to deduce the requirement to have tt pages decrypted by checking whether coherent dma allocations have been requested and the system is running with confidential computing technologies. This approach isn't ideal but keeping TTM matching DMAs expectations for the page properties is in general fragile, unfortunately proper fix would require a rewrite of TTM's page fault handling. Fixes vmwgfx with SEV enabled. v2: Explicitly include cc_platform.h v3: Use CC_ATTR_GUEST_MEM_ENCRYPT instead of CC_ATTR_MEM_ENCRYPT to limit the scope to guests and log when memory decryption is enabled.

This has caused mismatch between new dc state and the actual hardware state, because we missed odm programming. [HOW] - Detect odm change even for otg master pipe without a plane. - Update odm config before calling program pipes for pipe with planes. The commit also updates blank pattern programming when odm is changed without plane. This is because number of OPP is changed when ODM combine is changed.

If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. Thanks, Sasha ------------------ original commit in Linus's tree ------------------ From 675daf435e9f8e5a5eab140a9864dfad6668b375 Mon Sep 17 00:00:00 2001 From: Alex Williamson <alex.williamson(a)redhat.com> Date: Fri, 8 Mar 2024 16:05:27 -0700 Subject: [PATCH] vfio/platform: Create persistent IRQ handlers The vfio-platform SET_IRQS ioctl currently allows loopback triggering of an interrupt before a signaling eventfd has been configured by the user, which thereby allows a NULL pointer dereference. Rather than register the IRQ relative to a valid trigger, register all IRQs in a disabled state in the device open path. This allows mask operations on the IRQ to nest within the overall enable state governed by a valid eventfd signal. This decouples @masked, protected by the @locked spinlock from @trigger, protected via the @igate mutex. In doing so, it's guaranteed that changes to @trigger cannot race the IRQ handlers because the IRQ handler is synchronously disabled before modifying the trigger, and loopback triggering of the IRQ via ioctl is safe due to serialization with trigger changes via igate. For compatibility, request_irq() failures are maintained to be local to the SET_IRQS ioctl rather than a fatal error in the open device path. This allows, for example, a userspace driver with polling mode support to continue to work regardless of moving the request_irq() call site. This necessarily blocks all SET_IRQS access to the failed index.
