| * | spidernet: improve interrupt handlingIshizaki Kou2007-07-101-14/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We intend this patch to improve spidernet interrupt handling to be more strict. We had following problem and this patch solves it. -when CONFIG_DEBUG_SHIRQ=y, request_irq() calls handler(). -when spider_net_open() is called, it calls request_irq() which calls spider_net_interrupt(). -if some specific interrupt bit is set at this timing, it calls netif_rx_schedule() and spider_net_poll() is scheduled. -spider_net_open() calls netif_poll_enable() which clears the bit __LINK_STATE_RX_SCHED. -when spider_net_poll() is called, it calls netif_rx_complete() which causes BUG_ON() because __LINK_STATE_RX_SCHED is not set.

| * | 3cSOHO100-TX needs EXTRA_PREAMBLESteffen Klassert2007-07-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 3cSOHO100-TX needs a mdio_sync() before mdio_read() to read the MII transceiver registers properly. Adding EXTRA_PREAMBLE to drv_flags of the 3cSOHO100-TX will force this. This problem exists already for years (I checked back to 2.6.8). Setting duplex for the 3cSOHO100-TX was more or less a random process. Till 2.6.15 it was more likely that the diver ends up in half duplex mode, after the code change in 2.6.16 it was more likely to end up in full duplex mode. I wonder why nobody noticed this earier.

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>

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.

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 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>
| * | | libata-acpi: implement ata_acpi_associate()Tejun Heo2007-07-093-320/+54
| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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. This is way safer and simpler.
