[PATCH v2 0/2] xen/swiotlb: two fixes
From: Juergen Gross
Date: Thu Feb 13 2025 - 03:55:53 EST
Patch 1 removes an unneeded alignment requirement, which resulted in
exhausting the SWIOTLB with normal use cases.
Patch 2 allows to allocate larger continuous regions by reallocating
the frame list if needed.
Changes in V2:
- drop former patch 2 for now in order to avoid more lengthy discussion
- new patch 2
Juergen Gross (2):
xen/swiotlb: relax alignment requirements
x86/xen: allow larger contiguous memory regions in PV guests
