2018-06-25ahci: fix FIS I bit and PIO Setup FIS interruptPaolo Bonzini
The "I" bit in PIO Setup and D2H FISes is exclusively a device concept and the irqstatus register in the controller does not matter. The SATA spec says when it should be one; for D2H FISes in practice it is always set, while the PIO Setup FIS has several subcases that are documented in the patch. Also, the PIO Setup FIS interrupt is actually generated _after_ data has been received. Someone should probably spend some time reading the SATA specification and figuring out the more obscure fields in the PIO Setup FIS, but this is enough to fix SeaBIOS booting from ATAPI CD-ROMs over an AHCI controller.

2018-06-08ahci: move PIO Setup FIS before transfer, fix it for ATAPI commandsJohn Snow
The PIO Setup FIS is written in the PIO:Entry state, which comes before the ATA and ATAPI data transfer states. As a result, the PIO Setup FIS interrupt is now raised before DMA ends for ATAPI commands, and tests have to be adjusted. This is also hinted by the description of the command header in the AHCI specification, where the "A" bit is described as When ‘1’, indicates that a PIO setup FIS shall be sent by the device indicating a transfer for the ATAPI command. and also by the description of the ACMD (ATAPI command region): The ATAPI command must be either 12 or 16 bytes in length. The length transmitted by the HBA is determined by the PIO setup FIS that is sent by the device requesting the ATAPI command. QEMU, which conflates the "generator" and the "receiver" of the FIS into one device, always uses ATAPI_PACKET_SIZE, aka 12, for the length.

2018-02-14libqos: Track QTestState with QPCIBusEric Blake
When initializing a QPCIBus, track which QTestState the bus is associated with (so that a later patch can then explicitly use that test state for all communication on the bus, rather than blindly relying on global_qtest). Update the initialization functions to take another parameter, and update all callers to pass in state (for now, most callers get away with passing the current global_qtest as the current state, although this required fixing the order of initialization to ensure qtest_start() is called before qpci_init*() in rtl8139-test, and provided an opportunity to pass in the allocator in e1000e-test). Touch up some allocations to use g_new0() rather than g_malloc() while in the area, and simplify some code (all implementations of QOSOps provide a .init_allocator() that never fails).

2016-11-14ahci-test: test atapi read_cd with bcl, nb_sectors = 0John Snow
Commit 9ef2e93f introduced the concept of tagging ATAPI commands as NONDATA, but this introduced a regression for certain commands better described as CONDDATA. read_cd is such a command that both requires a non-zero BCL if a transfer size is set, but is perfectly content to accept a zero BCL if the transfer size is 0. This test adds a regression test for the case where BCL and nb_sectors are both 0. Flesh out the CDROM tests by: (1) Allowing the test to specify a BCL (2) Allowing the buffer comparison test to compare a 0-size buffer (3) Fix the BCL specification in libqos (It is LE, not BE) (4) Add a nice human-readable message for future SCSI command additions Signed-off-by: John Snow <jsnow@redhat.com> Reviewed-by: Kevin Wolf <kwolf@redhat.com> Message-id: 1477970211-25754-4-git-send-email-jsnow@redhat.com [Line length edit --js] Signed-off-by: John Snow <jsnow@redhat.com>
2016-10-28libqos: Change PCI accessors to take opaque BAR handleDavid Gibson
The usual use model for the libqos PCI functions is to map a specific PCI BAR using qpci_iomap() then pass the returned token into IO accessor functions. This, and the fact that iomap() returns a (void *) which actually contains a PCI space address, kind of suggests that the return value from iomap is supposed to be an opaque token. ..except that the callers expect to be able to add offsets to it. Which also assumes the compiler will support pointer arithmetic on a (void *), and treat it as working with byte offsets. To clarify this situation change iomap() and the IO accessors to take a definitely opaque BAR handle (enforced with a wrapper struct) along with an offset within the BAR. This changes both the functions and all the callers. There were a number of places that checked if iomap() returned non-NULL, and or initialized it to NULL before hand. Since iomap() already assert()s if it fails to map the BAR, these tests were mostly pointless and are removed.

2016-10-28tests: Don't assume structure of PCI IO base in ahci-testDavid Gibson
In a couple of places ahci-test makes assumptions about how the tokens returned from qpci_iomap() are formatted in ways it probably shouldn't. First in verify_state() it uses a non-NULL token to indicate that the AHCI device has been enabled (part of enabling is to iomap()). This changes it to use an explicit 'enabled' flag instead. Second, it uses the fact that the token contains a PCI address, stored when the BAR is mapped during initialization to check that the BAR has the same value after a migration. This changes it to explicitly read the BAR register before and after the migration and compare. Together, these changes will make the test more robust against changes to the internals of the libqos PCI layer.

2015-02-16libqos/ahci: add ahci command functionsJohn Snow
This patch adds the AHCICommand structure, and a set of functions to operate on the structure. ahci_command_create - Initialize and create a new AHCICommand in memory ahci_command_free - Destroy this object. ahci_command_set_buffer - Set where the guest memory DMA buffer is. ahci_command_commit - Write this command to the AHCI HBA. ahci_command_issue - Issue the committed command synchronously. ahci_command_issue_async - Issue the committed command asynchronously. ahci_command_wait - Wait for an asynchronous command to finish. ahci_command_slot - Get the number of the command slot we committed to. Helpers: size_to_prdtl - Calculate the required minimum PRDTL size from a buffer size. ahci_command_find - Given an ATA command mnemonic, look it up in the properties table to obtain info about the command. command_header_init - Initialize the command header with sane values. command_table_init - Initialize the command table with sane values.

2015-02-16libqos/ahci: Add ide cmd propertiesJohn Snow
Add a structure that defines some properties of various IDE commands. These will be used to simplify the interface to the libqos AHCI calls, lessening the redundancy of specifying and respecifying properties of commands to various helper functions.

Similar to ahci_set_command_header, add a helper that takes an in-memory representation of a command FIS and writes it to guest memory, handling endianness as-needed.
