* libqtest: Add qtest_[v]startf()Eric Blake2017-10-201-21/+12Star
| | | | | | | | | | | | | | | | | | | | | We have several callers that were formatting the argument strings themselves; consolidate this effort by adding new convenience functions directly in libqtest, and update some call-sites that can benefit from it. Note that the new functions qtest_startf() and qtest_vstartf() behave more like qtest_init() (the caller must assign global_qtest after the fact, rather than getting it implicitly set). This helps us prepare for future patches that get rid of the global variable, by explicitly highlighting which tests still depend on it now.

* spapr: Improved placement of PCI host bridges in guest memory mapDavid Gibson2016-10-161-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the MMIO space for accessing PCI on pseries guests begins at 1 TiB in guest address space. Each PCI host bridge (PHB) has a 64 GiB chunk of address space in which it places its outbound PIO and 32-bit and 64-bit MMIO windows. This scheme as several problems: - It limits guest RAM to 1 TiB (though we have a limited fix for this now) - It limits the total MMIO window to 64 GiB. This is not always enough for some of the large nVidia GPGPU cards - Putting all the windows into a single 64 GiB area means that naturally aligning things within there will waste more address space. In addition there was a miscalculation in some of the defaults, which meant that the MMIO windows for each PHB actually slightly overran the 64 GiB region for that PHB. We got away without nasty consequences because the overrun fit within an unused area at the beginning of the next PHB's region, but it's not pretty. This patch implements a new scheme which addresses those problems, and is also closer to what bare metal hardware and pHyp guests generally use. Because some guest versions (including most current distro kernels) can't access PCI MMIO above 64 TiB, we put all the PCI windows between 32 TiB and 64 TiB. This is broken into 1 TiB chunks. The first 1 TiB contains the PIO (64 kiB) and 32-bit MMIO (2 GiB) windows for all of the PHBs. Each subsequent TiB chunk contains a naturally aligned 64-bit MMIO window for one PHB each. This reduces the number of allowed PHBs (without full manual configuration of all the windows) from 256 to 31, but this should still be plenty in practice. We also change some of the default window sizes for manually configured PHBs to saner values. Finally we adjust some tests and libqos so that it correctly uses the new default locations. Ideally it would parse the device tree given to the guest, but that's a more complex problem for another time.

* coccinelle: Remove unnecessary variables for function return valueEduardo Habkost2016-06-201-4/+1Star

| | | | | | | | | | | | | | | | | | | | This avoids each test needing to add it to suppress windows popping up. [Commit 7ceeedd016facf8d58e14a0d1417fa7225d71072 ("blockdev-test: add test case for drive_add duplicate IDs") and commit 43cd209803d6cffb1e1a028c9ff2fd0ff4fce954 ("qdev-monitor-test: add device_add leak test cases") added qtest tests without specifying -display none. As a result, "make check" now tries to use graphics (GTK or SDL). Since graphics are not used by the test and inappropriate for headless "make check" runs, add the missing -display none.
