For each deficiency, the known workaround and the operating constraints, with and without the workaround, are also described. Table 2 provides a summary of the functional deficiencies. Please report any functional deficiencies not covered in this errata document to PMC-Sierra, Inc. Table 2 Section 2.1 Summary of Functional Deficiencies Discrepancy Driver Fails to report add bus parity error interrupts Workaround Yes - edit code 2.1 2.1.1 Driver fails to report add bus parity error interrupts Description When configured in ISR mode, the driver can not service the add bus parity error interrupt (API1, API2, API3 and API4 in Section/Line Block Interrupt Status register 000BH). When configured in polling mode the driver services the interrupts correctly. 2.1.2 Workaround The current implementation of the driver assumes that the add bus parity error interrupt (API1, API2, API3 and API4 in Section/Line Block Interrupt Status register 000BH) are covered by one of the master interrupt status bits within register 000BH (SPECTRA-622 Section/Line Block Interrupt Status register): CSPII or CRSII. This is incorrect and therefore code modifications must be made to the isrSpectraGetStatusIO(), isrSpectraGetStatus(), and isrSpectraPollStatus() functions located in spe_isr.c. isrSpectraGetStatusIO() should be updated by removing the following code: /* SPECTRA-622 ADD Bus Parity Interrupt Status */ addr = base + SPE_REG_ADD_BUS_PARITY_INT_STAT; val = sysSpectraRead(addr); pmask->ioApe[0] = val & SPE_BTMSK_IO_API1; pmask->ioApe[1] = val & SPE_BTMSK_IO_API2; pmask->ioApe[2] = val & SPE_BTMSK_IO_API3; pmask->ioApe[3] = val & SPE_BTMSK_IO_API4; isrSpectraPollStatus() should be updated by replacing the following code: /* clear the isv mask */ sysSpectraMemSet(pmask, 0, sizeof(sSPE_MASK)); Proprietary and Confidential to PMC-Sierra, Inc., and for its Customers' Internal Use Document ID: PMC-2000842, Issue 2 7 PM5313 SPECTRA-622 Device Driver Errata Released isrSpectraGetStatusIO (pddb, pmask); with: UINT1 * base, * addr; UINT1 val; /* clear the isv mask */ sysSpectraMemSet(pmask, 0, sizeof(sSPE_MASK)); /* SPECTRA-622 ADD Bus Parity Interrupt Status */ addr = base + SPE_REG_ADD_BUS_PARITY_INT_STAT; val = sysSpectraRead(addr); pmask->ioApe[0] = val & SPE_BTMSK_IO_API1; pmask->ioApe[1] = val & SPE_BTMSK_IO_API2; pmask->ioApe[2] = val & SPE_BTMSK_IO_API3; pmask->ioApe[3] = val & SPE_BTMSK_IO_API4; isrSpectraGetStatusIO (pddb, pmask); isrSpectraGetStatus(), should be updated by replacing the following code: baddr = pddb->baseAddr; /* read the SPECTRA-622 Section/Line Block Interrupt Status register */ with: baddr = pddb->baseAddr; /* SPECTRA-622 ADD Bus Parity Interrupt Status */ addr = baddr + SPE_REG_ADD_BUS_PARITY_INT_STAT; val = sysSpectraRead(addr); pmask->ioApe[0] = val & SPE_BTMSK_IO_API1; pmask->ioApe[1] = val & SPE_BTMSK_IO_API2; pmask->ioApe[2] = val & SPE_BTMSK_IO_API3; pmask->ioApe[3] = val & SPE_BTMSK_IO_API4; /* read the SPECTRA-622 Section/Line Block Interrupt Status register */ 2.1.3 Performance With Workaround When configured in ISR mode or polling mode, the driver services an add bus parity error interrupt (API1, API2, API3 and API4 in Section/Line Block Interrupt Status register 000BH) correctly. Proprietary and Confidential to PMC-Sierra, Inc., and for its Customers' Internal Use Document ID: PMC-2000842, Issue 2 8 PM5313 SPECTRA-622 Device Driver Errata Released 2.1.4 Performance Without Workaround When configured in ISR mode, an add bus parity error interrupt (API1, API2, API3 and API4 in Section/Line Block Interrupt Status register 000BH) the driver will not service the interrupts and will lock the system in the ISR.
