@ -70,11 +70,13 @@ Determining memory
You will need to adjust the memory size to be suitable for your desired maximum
resolution, with the following formula:
``width x height x pixel size x 2 = frame bytes``
.. code::
``total bytes / 1024 / 1024 = frame megabytes``
width x height x pixel size x 2 = frame bytes
``total megabytes + 10 = total size required``
total bytes / 1024 / 1024 = frame megabytes
frame megabytes + 10 MiB = total megabytes
Where `pixel size` is 4 for 32-bit RGB (SDR) or 8 for 64-bit
(HDR :ref:`* <libvirt_determining_memory_hdr>`).

For example, for a resolution of 1920x1080 (1080p):
``1920 x 1080 x 4 x 2 = 16,588,800 bytes``
.. code::
``16,588,800 / 1024 / 1024 = 15.82 MiB``
1920 x 1080 x 4 x 2 = 16,588,800 bytes
``15.82 MiB + 10 MiB = 25.82 MiB``
16,588,800 / 1024 / 1024 = 15.82 MiB
15.82 MiB + 10 MiB = 25.82 MiB
You must round this value up to the nearest power of two, which for the
provided example is 32 MiB.
