2019-01-24T16:13:59+00:00

Correct the persistent register offset where address and status are
stored.

EDAC, altera: Add Stratix10 peripheral support

2018-09-25T19:22:20+00:00

Add a new peripheral ECC error injection algorithm for Stratix10 and
some Arria10 peripherals. Inject a single bit error and upon readback,
it will be corrected and the SBE IRQ handler will be called.

Add regmap selection for Stratix10 or Arria10 peripheral device memory
initialization.

Add checks for both Arria10 and Stratix10 to the peripheral ECC setup.

EDAC, altera: Merge Stratix10 into the Arria10 SDRAM probe routine

2018-09-25T19:21:26+00:00

Change Stratix10 regmap to use offsets from a base to match
the Arria10 regmap and allow re-use of the Arria10 functions.
Only the regmap initialization differs (Arria10 mmio_regmap
vs Stratix10 custom regmap).

Modify the SDRAM probe function to handle Stratix10. Remove the
Stratix10 offset defines if Arria10 can be used. Remove the unused
Stratix10 probe function.

EDAC, altera: Combine Stratix10 and Arria10 probe functions

2018-09-25T19:17:38+00:00

On Stratix10, the ECC offsets are similar to the existing
Arria10 functions and this can be leveraged to simplify
the EDAC driver as follows:

1. Fold Stratix10 specifics into Arria10 structures and
functions.

2. Implement the Stratix10 System Manager register accesses
using a custom regmap to allow use with the Arria10 System
Manager regmaps.

3. Stratix10 double bit errors are implemented as SError
instead of interrupts so use a panic notifier.

EDAC, altera: Handle SDRAM Uncorrectable Errors on Stratix10

2018-05-12T10:29:41+00:00

On Stratix10, uncorrectable errors are routed to the SError exception
instead of the IRQ exceptions. In Stratix10, uncorrectable SErrors
must be treated as fatal and will cause a panic. Older Altera/Intel
parts printed out a message for UE so do that here using the notifier
framework.

Record the UE in sticky registers that retain the state through a reset.
Check these registers on probe and printout the error on startup.

EDAC, altera: Add support for Stratix10 SDRAM EDAC

2018-05-12T09:13:39+00:00

Support for Stratix10 SDRAM ECC requires the use of SMC calls to Secure
Monitor for accessing registers.

EDAC, altera: Rename device trigger to common name

2016-09-01T06:55:24+00:00

The L2 and OCRAM devices have different ecc trigger names than the other
EDAC devices (FIFO peripherals). Make them all the same and remove the
character array from the device structure.

EDAC, altera: Add Arria10 SD-MMC EDAC support

2016-08-10T12:43:14+00:00

Add Altera Arria10 SD-MMC FIFO memory EDAC support. The SD-MMC is a
dual port RAM implementation which is different than any of the other
peripherals and therefore requires additional code.
