Hi Sudeep, Cheers for sorting it out... On 28/02/18 15:48, Sudeep Holla wrote:
Currently the size of GICv2m MSI frames are listed as 4kB while the Juno TRM specifies 64kB for each of these MSI frames. Though the devices connected themself might just use the first 4kB,
s/themself/themselves/
to be consistent with the genaral practice of 64kB boundary alignment
s/genaral/general/
to all the devices, lets keep the size as 64kB. This might also help in avoiding any surprise when passing the device to a VM. This patch increase the size of each GICv2m MSI frames from 4kB to 64kB as per the specification.
