  5342. * as "scan-off". Real-life scenario for example: if a driver is being
  5343. * load-unloaded while func6,7 are down. This will cause the timer to access
  5344. * the ilt, translate to a logical address and send a request to read/write.
  5345. * Since the ilt for the function that is down is not valid, this will cause
  5346. * a translation error which is unrecoverable.
  5347. * The Workaround is intended to make sure that when this happens nothing fatal
  5348. * will occur. The workaround:
  5349. * 1. First PF driver which loads on a path will:
  5350. * a. After taking the chip out of reset, by using pretend,
  5351. * it will write "0" to the following registers of

  5353. * REG_WR(pdev, PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER, 0);
  5354. * REG_WR(pdev, CFC_REG_WEAK_ENABLE_PF,0);
  5355. * REG_WR(pdev, CFC_REG_STRONG_ENABLE_PF,0);
  5356. * And for itself it will write '1' to
  5357. * PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER to enable
  5358. * dmae-operations (writing to pram for example.)
  5359. * note: can be done for only function 6,7 but cleaner this
  5360. * way.
  5361. * b. Write zero+valid to the entire ILT.
  5362. * c. Init the first_timers_ilt_entry, last_timers_ilt_entry of
  5363. * VNIC3 (of that port). The range allocated will be the
  5364. * entire ILT. This is needed to prevent ILT range error.
  5365. * 2. Any PF driver load flow:
  5366. * a. ILT update with the physical addresses of the allocated
  5367. * logical pages.
  5368. * b. Wait 20msec. - note that this timeout is needed to make
  5369. * sure there are no requests in one of the PXP internal
  5370. * queues with "old" ILT addresses.
  5371. * c. PF enable in the PGLC.
  5372. * d. Clear the was_error of the PF in the PGLC. (could have
  5373. * occured while driver was down)
  5374. * e. PF enable in the CFC (WEAK + STRONG)
  5375. * f. Timers scan enable
  5376. * 3. PF driver unload flow:
  5377. * a. Clear the Timers scan_en.
  5378. * b. Polling for scan_on=0 for that PF.
  5379. * c. Clear the PF enable bit in the PXP.
  5380. * d. Clear the PF enable in the CFC (WEAK + STRONG)
  5381. * e. Write zero+valid to all ILT entries (The valid bit must
  5382. * stay set)
  5383. * f. If this is VNIC 3 of a port then also init
  5384. * first_timers_ilt_entry to zero and last_timers_ilt_entry
  5385. * to the last enrty in the ILT.
  5386. *
  5387. * Notes:
  5388. * Currently the PF error in the PGLC is non recoverable.
  5389. * In the future the there will be a recovery routine for this error.
  5390. * Currently attention is masked.
  5391. * Having an MCP lock on the load/unload process does not guarantee that
  5392. * there is no Timer disable during Func6/7 enable. This is because the
  5393. * Timers scan is currently being cleared by the MCP on FLR.
  5394. * Step 2.d can be done only for PF6/7 and the driver can also check if
  5395. * there is error before clearing it. But the flow above is simpler and
  5396. * more general.
  5397. * All ILT entries are written by zero+valid and not just PF6/7
  5398. * ILT entries since in the future the ILT entries allocation for
  5399. * PF-s might be dynamic.
