There is an issue with iasl on big endian machines: It cannot disassemble acpi tables taken from little endian machines, so we cannot check the expected tables.
Do not run iasl on those machines until this problem is solved by the acpica community. Signed-off-by: Marcel Apfelbaum <marce...@redhat.com> --- V2 -> V3: Addressed Michael S. Tsirkin's review: - tests don't need to re-run detection, use configure to figure out if it is an LE machine. V1 -> V2: Addressed an offline tip for a much cleaner macro line, thanks! configure | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/configure b/configure index aae617e..2c0a3b2 100755 --- a/configure +++ b/configure @@ -4656,7 +4656,10 @@ else fi echo "PYTHON=$python" >> $config_host_mak echo "CC=$cc" >> $config_host_mak -if $iasl -h > /dev/null 2>&1; then +# All known versions of iasl on BE machines are broken. +# TODO: add detection code once a non-broken version makes an appearance. +if ($iasl -h > /dev/null 2>&1) && + (lscpu | grep "Byte Order" | grep --quiet "Little Endian" ); then echo "IASL=$iasl" >> $config_host_mak fi echo "CC_I386=$cc_i386" >> $config_host_mak -- 1.8.3.1
