2015-02-16libqos/ahci: Add ahci_clean_memJohn Snow
Clean up guest memory being used in ahci_clean_mem, to be called during ahci_shutdown. With all guest memory leaks removed, add an option to the allocator to throw an assertion if a leak occurs. This test adds some sanity to both the AHCI library and the allocator.

2015-02-16libqos/ahci: add ahci_ioJohn Snow
ahci_io is a wrapper around ahci_guest_io that takes a pointer to host memory instead, and will create a guest memory buffer and copy the data to/from as needed and as appropriate for a read/write command, such that after a read, the guest data will be in a host buffer, and for a write, the data will be transmitted to guest memory prior to the block operation. Now that we have all the syntactic sugar functions in place for AHCI, we can convert the identify test to be very, very short.

To support the PIO sanity check, a new structure is added for the PIO Setup FIS type.

Adds command header helper functions: -ahci_command_header_set -ahci_command_header_get, -ahci_command_destroy, and -ahci_cmd_pick These helpers help to quickly manage the command header information in the AHCI device. ahci_command_header_set and get will store or retrieve an AHCI command header, respectively. ahci_cmd_pick chooses the first available but least recently used command slot to allow us to cycle through the available command slots. ahci_command_destroy obliterates all information contained within a given slot's command header, and frees its associated command table, but not its DMA buffer! Lastly, the command table pointer fields (dba and dbau) are merged into a single 64bit value to make managing 64bit tests simpler.

2015-02-16qtest/ahci: Store hba_base in AHCIQStateJohn Snow
Store the HBA memory base address in the new state object, to simplify function prototypes and encourage a more functional testing style. This causes a lot of churn, but this patch is as "simplified" as I could get it to be. This patch is therefore fairly mechanical and straightforward: Any case where we pass "hba_base" has been consolidated into the AHCIQState object and we pass the one unified parameter. Any case where we reference "ahci" and "hba_state" have been modified to use "ahci->dev" for the PCIDevice and "ahci->hba_state" to get at the base memory address, accordingly. Notes: - A needless return is removed from start_ahci_device. - For ease of reviewing, this patch can be reproduced (mostly) by: # Replace (ahci, hba_base) prototypes with unified parameter 's/(QPCIDevice \*ahci, void \*\?\*hba_base/(AHCIQState *ahci/' # Replace (ahci->dev, hba_base) calls with unified parameter 's/(ahci->dev, &\?hba_base)/(ahci)/' # Replace calls to PCI config space using "ahci" with "ahci->dev" 's/qpci_config_\(read\|write\)\(.\)(ahci,/qpci_config_\1\2(ahci->dev,/' After these, the remaining differences are easy to review by hand.

2015-02-16libqos: Update QGuestAllocator to be opaqueJohn Snow
To avoid the architecture-specific implementations of the generic qtest allocator having to know about fields within the allocator, add a page_size setter method for users or arch specializations to use. The allocator will assume a default page_size for general use, but it can always be overridden. Since this was the last instance of code directly using properties of the QGuestAllocator object directly, modify the type to be opaque and move the structure inside of malloc.c. mlist_new, which was previously exported, is made static local to malloc.c, as it has no external users.

2015-02-16libqos: create libqos.cJohn Snow
The intent of this file is to serve as a misc. utilities file to be shared amongst tests that are utilizing libqos facilities. In a later patch, migration test helpers will be added to libqos.c that will allow simplified testing of migration cases where libqos is "Just Enough OS" for migrations testing. The addition of the AHCIQState structure will also allow us to eliminate global variables inside of qtests to manage allocators and test instances in a better, more functional way. libqos.c: - Add qtest_boot - Add qtest_shutdown libqos.h: - Create QOSState structure for allocator and QTestState. ahci-test.c: - Move qtest_boot and qtest_shutdown to libqos.c/h - Create AHCIQState to interface with new qtest_boot/shutdown prototypes - Modify tests slightly to use new types.

2014-09-29libqos: use microseconds instead of iterations for virtio timeoutStefan Hajnoczi
Some hosts are slow or overloaded so test execution takes a long time. Test cases use timeouts to protect against an infinite loop stalling the test forever (especially important in automated test setups). Commit 6cd14054b67774cc58a51fca6660cfa1d3c08059 ("libqos virtio: Increase ISR timeout") increased the clock_step() value in an attempt to lengthen the virtio interrupt wait timeout, but timeout failures are still occuring on the Travis automated testing platform. This is because clock_step() only affects the guest's virtual time. Virtio requests can be bottlenecked on host disk I/O latency - which cannot be improved by stepping the clock, so the fix was ineffective. This patch changes the qvirtio_wait_queue_isr() and qvirtio_wait_config_isr() timeout mechanism from loop iterations to microseconds. This way the test case can specify an absolute 30 second timeout. Number of loop iterations is not a reliable timeout mechanism since the speed depends on many factors including host performance. Tests should no longer timeout on overloaded Travis instances.

2014-09-29libqos: improve event_index test with timeoutStefan Hajnoczi
The virtio event_index feature lets the device driver tell the device how many requests to process before raising the next interrupt. virtio-blk-test.c tries to verify that the device does not raise an interrupt unnecessarily. Unfortunately the test has a race condition. It spins checking for an interrupt up to 100 times and then assumes the request has finished. On a slow host the I/O request could still be in flight and the test would fail. This patch waits for the request to complete, or until a 30-second timeout is reached. If an interrupt is raised while waiting the test fails since the device was not supposed to raise interrupts.

2014-09-08tests: Functions bus_foreach and device_find from libqos virtio APIMarc Marí
Virtio header has been changed to compile and work with a real device. Functions bus_foreach and device_find have been implemented for PCI. Virtio-blk test case now opens a fake device.

2014-08-15libqos: allow qpci_iomap to return BAR mapping sizeJohn Snow
This patch allows qpci_iomap to return the size of the BAR mapping that it created, to allow driver applications (e.g, ahci-test) to make determinations about the suitability or the mapping size, or in the specific case of AHCI, how many ports are supported by the HBA.

2014-07-15libqos: Fix PC PCI endianness glitchesAndreas Färber
The libqos implementation of io_read{b,w,l} and io_write{b,w,l} hooks was relying on qtest_mem{read,write}() respectively. With d81d410 (usb: improve ehci/uhci test) this resulted in assertion failures on ppc hosts: ERROR:tests/usb-hcd-ehci-test.c:78:ehci_port_test: assertion failed: ((value & mask) == (expect & mask)) ERROR:tests/usb-hcd-ehci-test.c:128:pci_uhci_port_2: assertion failed: (pcibus != NULL) ERROR:tests/usb-hcd-ehci-test.c:150:pci_ehci_port_2: assertion failed: (pcibus != NULL) qtest_read{b,w,l,q}() and qtest_write{b,w,l,q}() had been introduced as endian-safe replacement for qtest_mem{read,write}() in I2C in 872536b (qtest: Add MMIO support). Use them for PCI as well.
