| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update sata_nv to wait for the controller to indicate via the status register that it has entered the requested state when switching between ADMA mode and register mode. This issue came up recently when debugging some problems with cache flush command timeouts and while it didn't appear to fix that problem, this is something we should likely be doing in any case.

| * sata_nv: use ADMA for NODATA commandsRobert Hancock2007-02-091-7/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some problems showed up recently with cache flush commands timing out on sata_nv. Previously these commands were always handled by transitioning to legacy mode from ADMA mode first. The timeout problem was worked around already by a change to the interrupt handling code for legacy mode, but for non-data commands like these it appears we can handle them in ADMA mode, so the switch to legacy mode is not needed. This patch changes the behavior so that we use ADMA mode to submit interrupt-driven commands with ATA_PROT_NODATA protocol. In addition to avoiding the problem mentioned above entirely, this avoids the overhead of switching to legacy mode and back to ADMA mode for handling cache flushes. When handling non-DMA-mapped commands, we leave the APRD blank and clear the NV_CPB_CTL_APRD_VALID field in the CPB so the controller does not attempt to read it.

| * sata_nv: cleanup ADMA error handlingRobert Hancock2007-02-091-75/+72
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This cleans up a few issues with the error handling in sata_nv in ADMA mode to make it more consistent with other NCQ-capable drivers like ahci and sata_sil24: - When a command failed, we would effectively set AC_ERR_DEV on the queued command always. In the case of NCQ commands this prevents libata from doing a log page query to determine the details of the failed command, since it thinks we've already analyzed. Just set flags in the port ehi->err_mask, then freeze or abort and let libata figure out what went wrong. - The code handled NV_ADMA_STAT_CPBERR as a "really bad error" which caused it to set error flags on every queued command. I don't know exactly what this flag means (no docs, grr!) but from what I can guess from the standard ADMA spec, it just means that one or more of the CPBs had an error, so we just need to go through and do our normal checks in this case. - In the error_handler function the code would always dump the state of all the CPBs. This output seems redundant at this point since libata already dumps the state of all active commands on errors (and it also triggers at times when it shouldn't, like when suspending). Take this out.

This patch simplifies initialization and fixes many resource related bugs in init failure and detach path. For example, all converted drivers now handle ata_device_add() failure gracefully without excessive resource rollback code. As most resources are released automatically on driver detach, many drivers don't need or can do with much simpler ->{port|host}_stop(). In general, stop callbacks are need iff port or host needs to be given commands to shut it down. Note that freezing is enough in many cases and ports are automatically frozen before being detached.

A device driver can allocate arbirary size of devres data which is associated with a release function. On driver detach, release function is invoked on the devres data, then, devres data is freed. devreses are typed by associated release functions. Some devreses are better represented by single instance of the type while others need multiple instances sharing the same release function. Both usages are supported. devreses can be grouped using devres group such that a device driver can easily release acquired resources halfway through initialization or selectively release resources (e.g. resources for port 1 out of 4 ports). This patch adds devres core including documentation and the following managed interfaces. * alloc/free : devm_kzalloc(), devm_kzfree() * IO region : devm_request_region(), devm_release_region() * IRQ : devm_request_irq(), devm_free_irq() * DMA : dmam_alloc_coherent(), dmam_free_coherent(), dmam_declare_coherent_memory(), dmam_pool_create(), dmam_pool_destroy() * PCI : pcim_enable_device(), pcim_pin_device(), pci_is_managed() * iomap : devm_ioport_map(), devm_ioport_unmap(), devm_ioremap(), devm_ioremap_nocache(), devm_iounmap(), pcim_iomap_table(), pcim_iomap(), pcim_iounmap() Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (against libata #upstream + the ATAPI cleanup patch) reimplements sata_promise's ATAPI support to format ATAPI DMA commands as normal packets, and to issue them via the hardware's normal packet machinery. It turns out that the only reason for issuing ATAPI DMA commands via the pdc_issue_atapi_pkt_cmd() procedure was to perform two interrupt-fiddling steps for ATA_DFLAG_CDB_INTR devices. But these steps aren't needed because sata_promise sets ATA_FLAG_PIO_POLLING, which disables DMA for those devices. The remaining steps can easily be done in ATA taskfile packets. Concrete changes: - pdc_atapi_dma_pkt() is extended to program all packet setup steps, and not just contain the CDB; the sequence of steps exactly mirrors what pdc_issue_atapi_pkt_cmd() did - pdc_atapi_dma_pkt() needed more parameters: simplify it by just passing 'qc' and having it extract the data it needs - pdc_issue_atai_pkt_cmd() and its two helper procedures pdc_wait_for_drq() and pdc_wait_on_busy() are removed Tested on first- and second-generation chips, SATAPI and PATAPI, with no observable regressions.
