| | * libata: use ata_exec_internal() for PMP register accessTejun Heo2007-10-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PMP registers used to be accessed with dedicated accessors ->pmp_read and ->pmp_write. During reset, those callbacks are called with the port frozen so they should be able to run without depending on interrupt delivery. To achieve this, they were implemented polling. However, as resetting the host port makes the PMP to isolate fan-out ports until SError.X is cleared, resetting fan-out ports while port is frozen doesn't buy much additional safety. This patch updates libata PMP support such that PMP registers are accessed using regular ata_exec_internal() mechanism and kills ->pmp_read/write() callbacks. The following changes are made. * PMP access helpers - sata_pmp_read_init_tf(), sata_pmp_read_val(), sata_pmp_write_init_tf() are folded into sata_pmp_read/write() which are now standalone PMP register access functions. * sata_pmp_read/write() returns err_mask instead of rc. This is consistent with other functions which issue internal commands and allows more detailed error reporting. * ahci interrupt handler is modified to ignore BAD_PMP and spurious/illegal completion IRQs while reset is in progress. These conditions are expected during reset. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

After an SRST it is undefined whether the drive has gone back to PIO0. In order to talk safely we should talk slowly and carefully until we know. Thus when we do the reset if the controller has a pio setup method we call it to flip back to PIO 0 and a known state. After the reset completes the identify will then be done at the safe speed and the drive/controller will pick suitable faster modes and reconfigure the controller to these timings. As a side effect it means we force the controller to PIO 0 as we bring it up which fixes funnies on a few systems where the BIOS firmware leaves us in an interesting choice of modes, or embedded boxes with no firmware which come up in random states. For smart controllers there is nothing to do - they know about this internally.

| | * libata: Integrate ACPI-based PATA/SATA hotplug - version 5Matthew Garrett2007-10-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Modern laptops with hotswap bays still tend to utilise a PATA interface on a SATA bridge, generally with the host controller in some legacy emulation mode rather than AHCI. This means that the existing hotplug code in libata is unable to work. The ACPI specification states that these devices can send notifications when hotswapped, which avoids the need to obtain notification from the controller. This patch uses the existing libata-acpi code and simply registers a notification in order to trigger a rescan whenever the firmware signals an event.

This prevents the need to pore through standards documents to figure out the meaning of the bits in these registers when looking at error reports. Some bits that drivers/ide decoded are not decoded here, since the bits are either command-dependent or obsolete, and properly parsing them would add too much complexity.

However, it has a PMP DMA CS errata which requires port-wide resetting if commands are outstanding to three or more devices when an error occurs on one of them. ATAPI commands often result in CHECK SENSE and it's crucial to not reset them before fetching sense data. Unfortunately, ATAPI CHECK SENSE causes a lot of problem if command is outstanding to any other device usually resulting in port-wide reset.

To support PMP, a LLDD has to supply ops->pmp_read() and pmp_write(). If non-null, ->pmp_attach and ->pmp_detach are called on PMP attach and detach, respectively. ->pmp_read/write() can be called while the port is frozen, so they must be implemented by polling. This patch supplies several helpers to ease ->pmp_read/write() implementation. Also, irq_handler and error_handler must be PMP aware. Most of PMP aware EH can be done by calling ata_pmp_do_eh() with appropriate methods. PMP EH uses separate set of reset methods and this patch implements standard prereset, hardreset and postreset methods. This patch only implements PMP support.

| | * sata_via: kill SATA_PATA_SHARING register handlingTejun Heo2007-10-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SATA_PATA_SHARING register doesn't have anything to do with the SATA part of the controller. It indicates whether an extern SATA PHY is attached to the PATA part of the controller and if so how it is wired. As the PATA part is driven by pata_via, sata_via has no reason to care about that. Also, pata_via should work fine under all configurations. This patch removes unnecessary attach failures. It seems recent via chipsets are defaulting to different values or are actually connected to SATA PHY triggering this more often.

| | | | | | | | | | | | | | | | | | | | | | | | | | | In ata_set_max_sectors(), the highest nibble in LBA28 mode was missing. This made drives sized between 8G and 128G with HPA turned on to be resized to under 8G. Fix it. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
