SigniÞcant Differences

Feature Changes

This section summarizes signiÞcant feature changes between the revision of the PID7t-603e addressed by this document and the previous revision 1.0 (XPC603RRXnnnLA or XPC603RFEnnnLA where nnn is the core frequency).

This revision was for manufacturing improvements only; there are no functional differences between this revision 2.1 and the previous revision 1.0.

This revision is functionally equivalent to the PID7v-603e (Valiant) microprocessor Revision 2.1 (XPC603PFEnnnLE/ XPC603PRXnnnLE) including the following errata.

Errata

This section summarizes design defects or errors (errata) that are known to exist on this revision of the PID7t-603e. There may be additional errata that are not known or are not yet documented here which may cause the part to deviate from the functional description provided in the to the website at http://www.mot.com/SPS/PowerPC/ for the latest version of this Part Number SpeciÞcation or to your local Motorola sales ofÞce for later and/or more detailed description of the errata.

The known errata as of the date of this document are summarized below.

# Problem Description Impact Solutions

1 Snoop copyback causes dcbi to

broadcast wrong address.

2 Competition for reservation

with lwarx/stwcx may cause live-lock

3 Touch load causes incorrect

address to appear on memory bus

4 Write-thru stores followed by

dcbz followed by a snoop, all to the same cache line, may cause incoherency.

5 The broadcasting of dcbz

instructions may retry snoop accesses indeÞnately.

A snoop which causes a copyback and occurs in a one cycle window near a dcbi causes the dcbi to broadcast the address of the snoop copyback.

The problem occurs when two processors are competing on the bus for a reservation, and the bus is operating with address pipelining

A touch load (dcbt) preceded by an instruction that generates an exception causes a random address to appear on the memory bus

The sequence of write-thru stores followed by dcbz followed by a snoop, all to the same cache line, may cause incoherency.

A sequence of broadcast bcbz instructions may retry snoop accesses indeÞnately.

Only systems using both software and hardware coherency simultaneously.

System Hang Insert a bus clockÕs worth of

Systems issuing instructions which generate mmu exceptions one cycle before using a touch load instruction

The write-thru store is completed after the dcbz.

Snoop originator may timeout. Disable broadcasting of dcbz

Use software semaphores rather than rely on dcbi to invalidate cache lines shared across multiple processors.

no-ops before lwarx

Disable touch loads with NOOPTI bit in HID0.

Store zeroes rather than rely on dcbz to zero cache lines in areas of memory that are marked as write-thru and can be accessed via multiple logical addresses.

by marking the memory space being addressed by the dcbz instruction as not global in the BAT or PTE.
