Benjamin Herrenschmidt	0b82024b01	tests/xics: Ensure no compiler optimisations in delay() ... In case it would be tempted to "read ahead" the delay function Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>	5 years ago
Benjamin Herrenschmidt	311b653d80	tests: Fix Makefile.test to not allow host includes ... xics was including the host limits.h for example Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>	5 years ago
Paul Mackerras	03f9d7a97e	tests/xics: Fix assumption that interrupts happen immediately ... Currently the test writes to the XICS and then checks that the expected interrupt has happened. This turns into a stbcix instruction followed immediately by a load from the variable that indicates whether an interrupt has happened. It is possible for it to take a few cycles for the store to reach the XICS and the interrupt request signal to come back to the core, particularly with improvements to the load/store unit and dcache. This therefore adds a delay between storing to the XICS and checking for the occurrence of an interrupt, so as to give the signals time to propagate. The delay loop does an arbitrary 10 iterations, and each iteration does two loads and one store to (cacheable) memory. Signed-off-by: Paul Mackerras <paulus@ozlabs.org>	5 years ago
Benjamin Herrenschmidt	a87b86e54f	console: Replace putstr with puts ... It makes things a bit more standard and a bit nicer to read without all those strlen(). Also console.c takes care of adding the carriage returns before the linefeeds. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>	5 years ago
Michael Neuling	0076f8bf1d	XICS test case ... Checks interrupt masking and priorities. Adds to `make test_xics` which is run in `make check` also. Signed-off-by: Michael Neuling <mikey@neuling.org>	5 years ago
