Various hardware counters are exported via the ipath file system (since it is binary data). The old file format was very dependent on the HW offsets for these registers. Newer HCA chips can have different counters at different offsets. This patch adds a level of indirection to make the file format consistent across HCAs.

In preparation for upcoming chips that have different values for INFINIPATH_R_PORTENABLE_SHIFT, INFINIPATH_R_INTRAVAIL_SHIFT, INFINIPATH_R_TAILUPD_SHIFT, and portcfg_shift, remove the shared #defines and use device-specific variables instead.

A couple of chip bugs in the iba6110 and in the iba6120 are not in more recent chips. This first bug swaps two of the pioavail register locations. In the second bug, the chip can sometimes forget to dma the pio avail register to memory. We indicate the presence of these bugs with runtime flags and we indicate the presence of the flags by bumping the SWMINOR.

Different processors have different ordering restrictions for write combining. By taking advantage of this, we can eliminate some write barriers when writing to the send buffers. Signed-off-by: NRalph Campbell <ralph.campbell@qlogic.com> Signed-off-by: NRoland Dreier <rolandd@cisco.com>

At one time the ipath_minrev field was initialized prior to the ipath_init_iba6120_funcs call, but that is no longer the case, so the slower put_tid routine was always being used. Signed-off-by: NDave Olson <dave.olson@qlogic.com> Signed-off-by: NRoland Dreier <rolandd@cisco.com>

We are more careful to be sure that we don't lose information about changes that occurred while we were in freeze mode, when the chip will not notify us, and try to avoid false error interrupts while doing cleanup.

This centralizes the use of the abort functionality, removes the unneeded buffer cancel (abort does the same thing), sets up to ignore launch errors after abort, same as cancel. We need abort on exit from freeze mode to avoid having buffers stuck in the busy state, if a user process happened to complete the send while we were in freeze mode doing the recovery.

Define pkt rcvd 'type' in a way consistent with HW spec and chips. The hardware considers received packets of type 0 to be expected, and type 1 to be eager. The driver was calling the ipath_f_put_tid functions using a variable called 'type' set to 0 for eager and to 1 for expected packets. Worse, the iba6110 and iba6120 drivers used those values inconsistently. This was quite confusing. Now everything is consistent with the hardware.

The IPATH_RUNTIME_PBC_REWRITE and the IPATH_RUNTIME_LOOSE_DMA_ALIGN flags were not ever implemented correctly and did not turn out to be necessary. Remove the last vestiges of these flags but mark the spot with a comment to remind us to not reuse these flags in the interest of binary compatibility. The INFINIPATH_XGXS_SUPPRESS_ARMLAUNCH_ERR bit was also not found to be useful, so it was dropped in the cleanup as well.

The new LED blinking interface adds more contention for the unprotected GPIO pins that were already shared, though not commonly at the same time. We add locks to the accesses to these pins so that Read-Modify-Write is now safe. Some of these locks are added at interrupt context, so we shadow the registers which drive and inspect these pins to avoid the mmio read/writes. This mitigates the effects of the locks and hastens us through the interrupt. Add locking and always use shadows for registers controlling GPIO pins (ExtCtrl and GPIOout). The use of shadows implies doing less I/O, which can make I2C operation too fast on some platforms. An explicit udelay(1) in SCL manipulation fixes that.

When we want to find an InfiniPath HCA in a rack of nodes, it is often expeditious to blink the status LEDs via a userspace /sys file. A write-only led_override "file" is published per device. Writes to this file are interpreted as (string form) numbers, and the resulting value sent to ipath_set_led_override(). The upper eight bits are interpretted as a 4.4 fixed-point "frequency in Hertz", and the bottom two 4-bit values are alternately (D0..3, then D4..7) used by the board-specific LED-setting function to override the normal state.

Once upon a time, GPIO interrupts were rare. But then a chip bug in the waldo series forced the use of a GPIO interrupt to signal packet reception. This greatly increased the frequency of GPIO interrupts which have the gpio_mask bits set on the waldo chips. Other bits in the gpio_status register are used for I2C clock and data lines, these bits are usually on. An "unlikely" annotation leftover from the old days was improperly applied to these bits, and an unnecessary chip mmio read was being accessed in the interrupt fast path on waldo. Remove the stagnant unlikely annotation in the interrupt handler and keep a shadow copy of the gpio_mask register to avoid the slow mmio read when testing for interruptable GPIO bits.

Commit 51f65ebc ("IB/ipath - program intconfig register using new HT irq hook"), which fixed interrupts for HyperTransport HCAs, broke PCI Express HCAs, because for those HCAs, the driver uses the value of pdev->irq before pci_enable_msi() and ends up getting a totally bogus IRQ number. Fix this by using the value of pdev->irq after pci_enable_msi(). Signed-off-by: NRoland Dreier <rolandd@cisco.com>

We can sometimes trigger parity errors due to processor speculative reads to our write-combined memory (mostly seen on Woodcrest). Add a stats counter for these. Factored out the sendbuffererror buffer cancellation code so it can be used in the new handling; suppress likely subsequent error messages if within two jiffies of the cancellation.

We do a few more explicit checks for specific models, and now also support the old PathScale serial number style, or new QLogic style. This is backwards compatible with previous versions of software and hardware. That is, older software will see a plausible serial number and correct GUID when used with a new board, while newer software will correctly handle an older board.
