2023-02-14tests/qtest/npcm7xx_pwm-test: Be less verbose unless V=2Peter Maydell1-6/+21
The npcm7xx_pwm-test produces a lot of output at V=1, which means that on our CI tests the log files exceed the gitlab 500KB limit. Suppress the messages about exactly what is being tested unless at V=2 and above. This follows the pattern we use with qom-test.

2022-05-03tests: move libqtest.h back under qtest/Marc-André Lureau1-1/+1
Since commit a2ce7dbd917 ("meson: convert tests/qtest to meson"), libqtest.h is under libqos/ directory, while libqtest.c is still in qtest/. Move back to its original location to avoid mixing with libqos/.

2021-05-14tests/qtest/npcm7xx_pwm-test.c: Avoid g_assert_true() for non-test assertionsPeter Maydell1-2/+2
In the glib API, the distinction between g_assert() and g_assert_true() is that the former is for "bug, terminate the application" and the latter is for "test check, on failure either terminate or just mark the testcase as failed". For QEMU, g_assert() is always fatal, so code can assume that if the assertion fails execution does not proceed, but this is not true of g_assert_true(). In npcm7xx_pwm-test, the pwm_index() and pwm_module_index() functions include some assertions that are just guarding against possible bugs in the test code that might lead us to out-of-bounds array accesses. These should use g_assert() because they aren't part of what the test is testing and the code does not correctly handle the case where the condition was false. This fixes some Coverity issues where Coverity knows that g_assert_true() can continue when the condition is false and complains about the possible array overrun at various callsites.

2021-03-12tests/qtest: Test PWM fan RPM using MFT in PWM testHao Wu1-6/+199
This patch adds testing of PWM fan RPMs in the existing npcm7xx pwm test. It tests whether the MFT module can measure correct fan values for a PWM fan in NPCM7XX boards.

2021-01-29hw/misc: Fix arith overflow in NPCM7XX PWM moduleHao Wu1-2/+2
Fix potential overflow problem when calculating pwm_duty. 1. Ensure p->cmr and p->cnr to be from [0,65535], according to the hardware specification. 2. Changed duty to uint32_t. However, since MAX_DUTY * (p->cmr+1) can excceed UINT32_MAX, we convert them to uint64_t in computation and converted them back to uint32_t. (duty is guaranteed to be <= MAX_DUTY so it won't overflow.)

The pwm_qom_get function didn't free "response", which caused an indirect memory leak. So use qobject_unref() to fix it.
