Coverity notes that the code at the end of the loop in bmdma_prepare_buf() is unreachable. This is because in commit 9fbf0fa81fca8f527 ("ide: remove hardcoded 2GiB transactional limit") we removed the only codepath in the loop which could "break" out of it, but didn't notice that this meant we should also remove the code at the end of the loop.

2023-11-21ide/pci: introduce pci_ide_update_mode() functionMark Cave-Ayland1-0/+84
This function reads the value of the PCI_CLASS_PROG register for PCI IDE controllers and configures the PCI BARs and/or IDE ioports accordingly. In the case where we switch to legacy mode, the PCI BARs are set to return zero (as suggested in the "PCI IDE Controller" specification), the legacy IDE ioports are enabled, and the PCI interrupt pin cleared to indicate legacy IRQ routing. Conversely when we switch to native mode, the legacy IDE ioports are disabled and the PCI interrupt pin set to indicate native IRQ routing. The contents of the PCI BARs are unspecified, but this is not an issue since if a PCI IDE controller has been switched to native mode then its BARs will need to be programmed.

2016-04-12ide: don't lose pending dma statePavel Butsykin1-0/+4
If the migration occurs after the IDE DMA has been set up but before it has been initiated, the state gets lost upon save/restore. Specifically, ->dma_cb callback gets cleared, so, when the guest eventually starts bus mastering, the DMA never completes, causing the guest to time out the operation. OTOH all the infrastructure is already in place to restart the DMA if the migration happens while the DMA is in progress. So reuse that infrastructure, by setting bus->error_status based on ->dma_cmd in pre_save if ->dma_cb callback is already set but DMAING is clear. This will indicate the need for restart and make sure ->dma_cb is restored in ide_restart_bh(); howeover since DMAING is clear the state upon restore will be exactly "ready for DMA" as before the save.

Not that you can request a >2GiB transaction, but that's why checking for it makes no sense anymore. With the newer 'limit' parameter to prepare_buf, we no longer need a static limit. The maximum limit is still 2GiB, but the limit parameter is set to the current transaction size, which cannot surpass 32MiB (512 * 65536). If the PRDT surpasses the transactional size, then, we'll just carry out the normative underflow handling pathways instead of needing an extra, strange pathway that worries about hitting some logistical cap for the largest sglist we can support -- we'll never even attempt to build one that big anymore.

2015-07-04ide: add limit to .prepare_buf()John Snow1-5/+16
prepare_buf should not always grab as many descriptors as it can, sometimes it should self-limit. For example, an NCQ transfer of 1 sector with a PRDT that describes 4GiB of data should not copy 4GiB of data, it should just transfer that first 512 bytes. PIO is not affected, because the dma_buf_rw dma helpers already have a byte limit built-in to them, but DMA/NCQ will exhaust the entire list regardless of requested size. AHCI 1.3 specifies in section 6.1.6 Command List Underflow that NCQ is not required to detect underflow conditions. Non-NCQ pathways signal underflow by writing to the PRDBC field, which will already occur by writing the actual transferred byte count to the PRDBC, signaling the underflow. Our NCQ pathways aren't required to detect underflow, but since our DMA backend uses the size of the PRDT to determine the size of the transer, if our PRDT is bigger than the transaction (the underflow condition) it doesn't cost us anything to detect it and truncate the PRDT. This is a recoverable error and is not signaled to the guest, in either NCQ or normal DMA cases. For BMDMA, the existing pathways should see no guest-visible difference, but any bytes described in the overage will no longer be transferred before indicating to the guest that there was an underflow.

2015-03-10ide: move restart callback to common codePaolo Bonzini1-79/+0
With BMDMA specific excised from the restart functions, create a HBA-agnostic restart callback to be shared between the different HBAs. Change the callback registered with the vmstate_change handler to always point to ide_restart_cb instead of relying on the IDEDMAOps.restart_cb() member.

2015-02-06atapi migration: Throw recoverable error to avoid recoveryDr. David Alan Gilbert1-0/+11
(With the previous atapi_dma flag recovery) If migration happens between the ATAPI command being written and the bmdma being started, the DMA is dropped. Eventually the guest times out and recovers, but that can take many seconds. (This is rare, on a pingpong reading the CD continuously I hit this about ~1/30-1/50 migrates) I don't think we've got enough state to be able to recover safely at this point, so I throw a 'medium error, no seek complete' that I'm assuming guests will try and recover from an apparently dirty CD. OK, it's a hack, the real solution is probably to push a lot of ATAPI state into the migration stream, but this is a fix that works with no stream changes. Tested only on Linux (both RHEL5 (pre-libata) and RHEL7).
