/* These are here in an effort to more fully work around Spitfire Errata
|
||||
* #51. Essentially, if a memory barrier occurs soon after a mispredicted
|
||||
* branch, the chip can stop executing instructions until a trap occurs.
|
||||
* Therefore, if interrupts are disabled, the chip can hang forever.
|
||||
*
|
||||
* It used to be believed that the memory barrier had to be right in the
|
||||
* delay slot, but a case has been traced recently wherein the memory barrier
|
||||
* was one instruction after the branch delay slot and the chip still hung.
|
||||
* The offending sequence was the following in sym_wakeup_done() of the
|
||||
* sym53c8xx_2 driver:
|
||||
*
|
||||
* call sym_ccb_from_dsa, 0
|
||||
* movge %icc, 0, %l0
|
||||
* brz,pn %o0, .LL1303
|
||||
* mov %o0, %l2
|
||||
* membar #LoadLoad
|
||||
*
|
||||
* The branch has to be mispredicted for the bug to occur. Therefore, we put
|
||||
* the memory barrier explicitly into a "branch always, predicted taken"
|
||||
* delay slot to avoid the problem case.
