[Intel-gfx] [PATCH] drm/i915/uc: use io memcpy functions for device memory copy

2022-04-06 Thread Balasubramani Vivekanandan
When copying RSA use io memcpy functions if the destination address contains a GPU local memory address. Considering even the source address can be on local memory, a bounce buffer is used to copy from io to io. The intention of this patch is to make i915 portable outside x86 mainly on ARM64. Sign
