        PHKL_6291: PANIC
        PHKL_4979: PANIC

Path Name:  /hp-ux_patches/s700/9.X/PHKL_7664

Symptoms:
        PHKL_7664:
        VME2_USER_COPY transfers the SAME 256k bytes for data
         transfers larger than 256K.

        PHKL_6291:

        1) two process using the same A16 space can panic system
        2) vme2.h from PHKL_5725 did not contain intended fix.

        PHKL_5725:

        1) Some data tranfer errors are not reported
        2) Installation of PHKL_4979 could cause a PANIC
        3) A16 access can cause PANIC or system hang
        4) Unmmapping the same memory twice hangs system

Defect Description:
        PHKL_7664:
        Kernel data pointer was not being properly updated.

        PHKL_6291:

        1) ioctl VME2_MAP_ADDR did not advance process use count
           resulting in a panic after any vme process exits

        2) vme2.h from PHKL_5725 is incorrect

        PHKL_5725:

        1) Some data transfer errors were not reported by
           vme2_user_copy and vme_copy

        2) VME2_UNMAP_ADDR would hang system if an attempt was made
           to unmap previously unmapped memory

        3) After installing PHKL_4979 a call to vme_map_mem_to_bus2
           would panic the system.

        4) Testing vme access using the A16 address space would
           panic the system, A32 address space worked.

        PHKL_4979:
        An interrupt is left pending from when the bootrom probed
        for hardware.  When interrupts are enabled for the VME bus
        the interrupt comes through before an interrupt handler
        is ready for it.

        PHKL_4599:
        Fixes the A24/A32 direct map problem.  Fixes the EEPROM
        verify failure.  Adds fixed address support to vme_copy.
        Fixes VME powerup bus reset problem.

        PHKL_4427:
        Added 743i/748i hardware support. The handling of VME
        SYSRESET is now specified via vme_config (PHCO_4428)
        program.  Added support for the 743i/748i.

        PHKL_3396:
        Same as PHKL_3395 except VME SYSRESET is not asserted in
        vme_init PHKL_3395 is identical to PHKL_3396 with the
        single exception that the VME SYSRESET line is NOT
        asserted during vme_init.  The normal power on assertion
        will still occur, however during a reboot of a currently
        running slot 1 controller the assertion of VME SYSRESET
        when vme_init is called does NOT happen.

        PHKL_3395:
        Fixes D08 Interrupter Mask, Multiple A16 user maps,
        vme_test_and_set bus lock race condition This patch is the
        9.03 equivalent to 9.01 PHKL_3383.  It fixes a race
        condition where two processes could get a semaphore using
        vme_test_and_set becuase of a problem getting a VME bus
        lock.  It prevents a panic when two user processes map A16
        access the space.  It protects VME mapper setting calls from
        access by other processes.  It also provides for certain VME
        SCSI drivers.

                cp patch_source/PHKL_7664 .
                sh PHKL_7664

        3. Become root and run update:

                /etc/update [-r [kernel_gen_file]] -s \

        Update moves the original software to
        /system/PHKL_7664/orig.  Keep this file to recover from any
        potential problems.  You should move the .text file to
        /system/PHKL_7664 for future reference.

        To put this patch on a magnetic tape and update from the
        tape drive, use dd:
