So I did some experiments only focusing on read operation for now

Note: Also changing DMA_FROM_DEVICE to DMA_BIDIRECTIONAL in
pci_endpoint_test_read() resulted same behaviour for both 1 & 2.
3: After making sure -s was aligned to 128 bytes memset and crc32_le
in pci_epf_test_write() didnt hit above issues,
and now when I compared the crc value of both the buffers this
matched on endpoint!
4: Now focusing more in rootdevice, I added memset(buf, 0xDF,
reg->size); in pci_epf_test_write() function
and was dumping the contents of buffer in pci_endpoint_test_read()
with below function:
static void print_buffer(struct device *dev, void *buff_addr, size_t size)
{
size_t i;
u64 *addr = buff_addr;
for(i = 0; i < size; i += sizeof(addr))
dev_err(dev, "buf[%zu] : %llx\n", i, *addr);
dev_err(dev, "\n\n\n\n");
}
Below is the dump from pci_endpoint_test_read() of one passing case
and other no-passing case:
The contents of buffer match as expected, but the crc32_le is
differrent and I am clue-less why is this
being caused when using non-coherent memory.
