This is useful during debugging or bring-up.In this configuration, the device uses physical addresses and doesnot support scatter-gather lists, requiring physically contiguousbuffers.Implement carveout-backed allocation and integrate it into buffermanagement to support operation in physical address mode.Signed-off-by: Max Zhen <max.zhen@amd.com>Reviewed-by: Mario Limonciello (AMD) <superm1@kernel.org>Signed-off-by: Lizhi Hou <lizhi.hou@amd.com>Link: https://patch.msgid.link/20260427170949.2666601-1-lizhi.hou@amd.com List of files: /linux/drivers/accel/amdxdna/amdxdna_debugfs.c Mon, 27 Apr 2026 19:09:49 +0200 Max Zhen <max.zhen@amd.com>
