xsk: Require XDP_UMEM_TX_METADATA_LEN to actuate tx_metadata_len

2024-08-03T07:01:03Z

[ Upstream commit d5e726d9143c5624135f5dc9e4069799adeef734 ] Julian reports that commit 341ac980eab9 ("xsk: Support tx_metadata_len") can break existing use cases which don't zero-initialize xdp_umem_reg padding. Introduce new XDP_UMEM_TX_METADATA_LEN to make sure we interpret the padding as tx_metadata_len only when being explicitly asked.

m68k: amiga: Turn off Warp1260 interrupts during boot

2024-08-03T07:00:36Z

commit 1d8491d3e726984343dd8c3cdbe2f2b47cfdd928 upstream. On an Amiga 1200 equipped with a Warp1260 accelerator, an interrupt storm coming from the accelerator board causes the machine to crash in local_irq_enable() or auto_irq_enable(). Disabling interrupts for the Warp1260 in amiga_parse_bootinfo() fixes the problem.

drm/xe: Use write-back caching mode for system memory on DGFX

2024-08-03T07:00:31Z

commit 5207c393d3e7dda9aff813d6b3e2264370d241be upstream. The caching mode for buffer objects with VRAM as a possible placement was forced to write-combined, regardless of placement. However, write-combined system memory is expensive to allocate and even though it is pooled, the pool is expensive to shrink, since it involves global CPU TLB flushes. Moreover write-combined system memory from TTM is only reliably available on x86 and DGFX doesn't have an x86 restriction. So regardless of the cpu caching mode selected for a bo, internally use write-back caching mode for system memory on DGFX. Coherency is maintained, but user-space clients may perceive a difference in cpu access speeds. v2: - Update RB- and Ack tags. - Rephrase wording in xe_drm.h (Matt Roper) v3: - Really rephrase wording.

misc: fastrpc: Restrict untrusted app to attach to privileged PD

2024-07-03T14:17:53Z

Untrusted application with access to only non-secure fastrpc device node can attach to root_pd or static PDs if it can make the respective init request. This can cause problems as the untrusted application can send bad requests to root_pd or static PDs. Add changes to reject attach to privileged PDs if the request is being made using non-secure fastrpc device node.
