| | | | | | | | | | | | | | | | | | The ATA_UDMAx masks are self-documenting, and far better than manually writing in the hex mask. Note that pata_it8213 mask differed from the comment. Added a FIXME there. Signed-off-by: Jeff Garzik <jeff@garzik.org>
| * [libata] AHCI: Add support for Marvell AHCI-like chips (initially 6145)Jeff Garzik2007-07-091-3/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | Add support for the SATA portion of Marvell's AHCI-compatible chips. The PATA port capability, also available via AHCI, is disabled until support is completed. NCQ and PCI MSI are disabled by default. Marvell says "we use NCQ" in their drivers but "we do not use PCI MSI." Theoretically that implies we need to fix ahci.c to work with Marvell NCQ, but one wonders why Marvell NCQ is any different from other AHCI chips. Signed-off-by: Jeff Garzik <jeff@garzik.org>

| * sata_sil24: sil24_interrupt() micro-optimisationMikael Pettersson2007-07-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sil24_interrupt() loads host->ports[i] into a local variable, validates it, and then loads the value again in the call to sil24_host_intr(). This patch replaces the second load by a reference to the local variable. This is safe since no side-effects have occurred since the initial load. It also improves readability since it makes it clear that the parameter to sil24_host_intr() is the same value which was just validated.

| * libata-acpi: implement _GTM/_STM supportTejun Heo2007-07-094-5/+171
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement _GTM/_STM support. acpi_gtm is added to ata_port which stores _GTM parameters over suspend/resume cycle. A new hook ata_acpi_on_suspend() is responsible for storing _GTM parameters during suspend. _STM is executed in ata_acpi_on_resume(). With this change, invoking _GTF is safe on IDE hierarchy and acpi_sata check before _GTF is removed. ata_acpi_gtm() and ata_acpi_stm() implementation is taken from Alan Cox's pata_acpi implementation. ata_acpi_gtm() is fixed such that the result parameter is not shifted by sizeof(union acpi_object).

| * libata: reimplement ACPI invocationTejun Heo2007-07-095-99/+140
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch reimplements ACPI invocation such that, instead of exporting ACPI details to the rest of libata, ACPI event handlers - ata_acpi_on_resume() and ata_acpi_on_devcfg() - are used. These two functions are responsible for determining whether specific ACPI method is used and when. On resume, _GTF is scheduled by setting ATA_DFLAG_ACPI_PENDING device flag. This is done this way to avoid performing the action on wrong device device (device swapping while suspended). On every ata_dev_configure(), ata_acpi_on_devcfg() is called, which performs _SDD and _GTF. _GTF is performed only after resuming and, if SATA, hardreset as the ACPI spec specifies. As _GTF may contain arbitrary commands, IDENTIFY page is re-read after _GTF taskfiles are executed. If one of ACPI methods fails, ata_acpi_on_devcfg() retries on the first failure. If it fails again on the second try, ACPI is disabled on the device. Note that successful configuration clears ACPI failed status. With all feature checks moved to the above two functions, do_drive_set_taskfiles() is trivial and thus collapsed into ata_acpi_exec_tfs(), which is now static and converted to return the number of executed taskfiles to be used by ata_acpi_on_resume(). As failures are handled properly, ata_acpi_push_id() now returns -errno on errors instead of unconditional zero.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch cleans up ata_acpi_exec_tfs() and its friends. * Rename taskfile_array to ata_acpi_gtf and make it __packed as it's used as argument to ACPI method, and use pointer to ata_acpi_gtf and number of taskfiles to represent _GTF taskfiles instead of a pointer casted into unsigned long and byte count. This makes argument re-checking in do_drive_set_taskfiles() unnecessary. * Pointer in void * not in unsigned long. * Clean up do_drive_get_GTF() error handling and make do_drive_get_GTF() return number of taskfiles on success, 0 if _GTF doesn't exist or doesn't contain valid ata. -errno on other errors. * Remove superflous check for acpi->buffer.pointer. * Update taskfile_load_raw() such that printed messages look similar to the messages printed by ata_eh_report(). * s/do_drive_get_GTF/ata_dev_get_GTF/ s/do_drive_set_taskfiles/ata_dev_set_taskfiles/ Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Add acpi_handle to ata_host and ata_port. Rename ata_device->obj_handle to ->acpi_handle and move it above such that it doesn't get cleared on reconfiguration. * Replace ACPI node association which ata_acpi_associate() which is called once during host initialization. Unlike the previous implementation, ata_acpi_associate() uses ATA_FLAG_ACPI_SATA to choose between IDE or SATA ACPI hierarchy and uses simple child look up instead of recursive walk to match the nodes.

| * | [MIPS] rbtx4938: Fix secondary PCIC and glue internal NICsAtsushi Nemoto2007-07-102-63/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Fix pci ops for secondary PCIC * Do not reserve 1MB for PCI MEM region (leave PCIBIOS_MIN_MEM zero) * Use platform_device to provide ethernet addresses for internal NICs. (background: TX49XX SoCs include PCI NIC (TC35815 compatible) connected via its internal PCI bus, but the NIC's PROM interface is not connected to SEEPROM. So we must provide its ethernet address by another way.) * Check return value of early_read_config_word() Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
