Subject: [PATCH] Allow setting up to 8 bytes with the generic loader mainline
inclusion commit f42483d776bce29a9925ed61cc10eb27a5b2446c category: bugfix
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
---------------------------------------------------------------
The documentation for the generic loader says that "the maximum size of
the data is 8 bytes". However, attempts to set data-len=8 trigger the
following assertion failure:
../hw/core/generic-loader.c:59: generic_loader_reset: Assertion `s->data_len < sizeof(s->data)' failed.
The type of s->data is uint64_t (i.e. 8 bytes long), so I believe this
assert should use <= instead of <.
Fixes: e481a1f63c93 ("generic-loader: Add a generic loader")
