Hi Sunil, You're right.
The MMC DMA destination buffer (64-bit) actually allocated in EDK2 code and passed into the EDK2-platform MMC driver. Now that you mention it, I think I can allocate another buffer (force to use 32-bit) in the MMC driver and use that buffer for tx/rx. Then, copy the content from the buffer (32-bit) to the MMC destination buffer (64-bit). In this case, there is no need to change any code in EDK2 and this "boot service memory allocation" driver is no longer needed. I will remove this driver and add the handling in DwEmmcDxe.c in Patch V2. Thank you!! =) -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
