This is quick rework of the patch Uwe proposed but using Kconfig not ifdefs and user selection to sort out PATA support. Instead of ifdefs and requiring the user to select both drivers the SATA driver selects the PATA one. For neatness I've also moved the extern into the function that uses it.

'hdparm -I' doesn't work with ATAPI devices and sg_sat is not widely spread yet leaving no easy way to access ATAPI IDENTIFY data. Implement HDIO_GET_IDENTITY such that at least 'hdparm -i' works. Signed-off-by:

This I believe completes the PIIX range of support for libata This adds the table entries needed for the PIIX3, both a new PCI identifier and a new mode list. It also fixes an erroneous access to PCI configuration 0x48 on non UDMA capable chips. Signed-off-by:

This patch extends sata_promise to handle ATAPI_NODATA commands internally. However, commands destined to ATA_DFLAG_CDB_INTR devices are excluded from this and continue to be returned to libata. Concrete changes: - pdc_atapi_dma_pkt() is renamed to pdc_atapi_pkt(), and is extended to set up correct headers for NODATA packets - pdc_qc_prep() calls pdc_atapi_pkt() for ATAPI_NODATA - pdc_host_intr() handles ATAPI_NODATA - pdc_qc_issue_prot() sends ATAPI_NODATA packets via the chip's packet mechanism, except for CDB_INTR devices Tested on first- and second-generation chips, SATAPI and PATAPI, with no observable regressions.

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.

Here's a cleanup for yesterday's sata_promise ATAPI patch: - add and use a symbolic constant for the altstatus register - check return status from ata_busy_wait() - add missing newline in a warning printk() - update comment in pdc_issue_atapi_pkt_cmd() to clarify that the maybe-wait-for-INT issue cannot occur in the current driver, but may occur if the driver starts issuing ATAPI non-DMA commands as PDC packets Signed-off-by:

Driver for Initio 162x SATA controllers. ATA r/w, ATAPI r, hotplug and suspend/resume work. ATAPI w (recording, that is) broken. Feel free to fix it, but be warned, this controller is weird. Signed-off-by:

libata used two separate sets of variables to record request size and current offset for ATA and ATAPI. This is confusing and fragile. This patch replaces qc->nsect/cursect with qc->nbytes/curbytes and kills them. Also, ata_pio_sector() is updated to use bytes for qc->cursg_ofs instead of sectors. The field used to be used in bytes for ATAPI and in sectors for ATA. Signed-off-by:

There were several places where ATA ID strings are manually terminated and in some places possibly unterminated strings were passed to string functions which don't limit length like strstr(). This patch converts all of them over to ata_id_c_string(). Signed-off-by:

* Kill _OFS suffixes in ATA_ID_{SERNO|FW_REV|PROD}_OFS for consistency with other ATA_ID_* constants. * Kill ATA_SERNO_LEN * Add and use ATA_ID_SERNO_LEN, ATA_ID_FW_REV_LEN and ATA_ID_PROD_LEN. This change also makes ata_device_blacklisted() use proper length for fwrev. Signed-off-by: -

This patch adds ATAPI support to the sata_promise driver. This has been tested on both first- and second-generation chips (20378 and 20575), and with both SATAPI and PATAPI devices. CD-writing works. SATAPI DMA works on second-generation chips, but on first-generation chips SATAPI is limited to PIO due to what appears to be HW limitations. PATAPI DMA works on both first- and second-generation chips, but requires the separate PATA support patch before it can be used on TX2plus chips. The functional changes to the driver are: - remove ATA_FLAG_NO_ATAPI from PDC_COMMON_FLAGS - add ->check_atapi_dma() operation to enable DMA for bulk data transfers but force PIO for other ATAPI commands; this filter is from Promise's driver and largely matches pata_pdc207x.c - use a more restrictive ->check_atapi_dma() on first-generation chips to force SATAPI to always use PIO - add handling of ATAPI protocols to pdc_qc_prep(), pdc_host_intr(), and pdc_qc_issue_prot(): ATAPI_DMA is handled by the driver while non-DMA protocols are handed over to libata generic code - add pdc_issue_atapi_pkt_cmd() to handle the initial steps in issuing ATAPI DMA commands before sending the actual CDB; this procedure was ported from Promise's driver Signed-off-by:

This patch implements a simple way of setting up per-port flags on the SATA+PATA Promise TX2plus chips, which is a prerequisite for supporting the PATA port on those chips. It is based on the observation that ap->flags isn't really used until after ->port_start() has been invoked. So it places the "exceptional" per-port flags array in the driver's private host structure, and uses it in ->port_start() to finalise the port's flags. This patch obsoletes the #promise-sata-pata branch included in the #all branch. Signed-off-by:

Add a driver for the IT8213 which is a single channel ICH-ish PATA controller. As it is very different to the IT8211/2 it gets its own driver. There is a legacy drivers/ide driver also available and I'll post that once I get time to test it all out (probably early January). If anyone else needs the drivers/ide driver and wants to do the merge for drivers/ide (Bart ??) then I'll forward it. [akpm@osdl.org: add PCI ID, constify needed_pio[]] Signed-off-by:

remap() the region we get from mmap() to mark the fact that we are using all of the available slack space. Any slack space is used to form a simple brk region, and potentially more stack space than requested at load time. Any searches of the vma chain may well fail looking for stack (and especially arg) addresses if the remaping is not done. The simplest example is /proc/<pid>/cmdline, since the args are pretty much always at the top of the data/bss/stack region. Signed-off-by:
