| * | | | x86: fix more TSC clock source calibration errorsDave Johnson2007-10-23

If a CPU gave bad results on the 1st or 2nd run but good results on the 3rd, it wouldn't do the correct thing. No idea if any such CPU exists, but the patch below handles that case by discarding the bad runs. If a bad result (too quick, or too slow) occurs on any of the 3 runs it will be discarded. Also updated some comments to explain what's going on.

On investigation, the tsc_khz variable was significantly incorrect causing xtime to run slow. After a reboot tsc_khz was correct so I did a reboot test to see how often the problem occurred: Test was done on a 2000 Mhz Xeon system. Of 689 reboots, 8 of them had unacceptable tsc_khz values (>500ppm): range of tsc_khz # of boots % of boots ---------------- ---------- ---------- < 1999750 0 0.000% 1999750 - 1999800 21 3.048% 1999800 - 1999850 166 24.128% 1999850 - 1999900 241 35.029% 1999900 - 1999950 211 30.669% 1999950 - 2000000 42 6.105% 2000000 - 2000000 0 0.000% 2000050 - 2000100 0 0.000% [...] 2000100 - 2015000 1 0.145% << BAD 2015000 - 2030000 6 0.872% << BAD 2030000 - 2045000 1 0.145% << BAD 2045000 < 0 0.000% The worst boot was 2032.577 Mhz, over 1.5% off! It appears that on rare occasions, mach_countup() is taking longer to complete than necessary. I suspect that this is caused by the CPU taking a periodic SMI interrupt right at the end of the 30ms calibration loop. This would cause the loop to delay while the SMI BIOS hander runs. The resulting TSC value is beyond what it actually should be resulting in a higher tsc_khz. The below patch makes native_calculate_cpu_khz() take the best (shortest duration, lowest khz) run of it's 3 calibration loops. If a SMI goes off causing a bad result (long duration, higher khz) it will be discarded. With the patch applied, 300 boots of the same system produce good results: range of tsc_khz # of boots % of boots ---------------- ---------- ---------- < 1999750 0 0.000% 1999750 - 1999800 30 10.000% 1999800 - 1999850 166 55.333% 1999850 - 1999900 89 29.667% 1999900 - 1999950 15 5.000% 1999950 < 0 0.000% Problem was found and tested against 2.6.18.

So ditch the generic lock bitops, and implement optimised versions for x86, which removes the mfence from __clear_bit_unlock (which is already a useful primitive for SLUB).

For recent ISPs, software during CS_UNDERRUN handling must determine if the two residuals, firmware-calculated and FCP_RSP, are different to recognize if a frame has been dropped. Update the driver to catch this condition, and clear the SS_RESIDUAL_UNDER and lscsi_status bits. This logic is consistent with what earlier firmwares did by explicitly cracking open the FCP_RSP statuses and clearing SS_RESIDUAL_UNDER.

| * | | | [SCSI] qla1280: eliminate wasted space in request and response ringJohannes Dickgreber2007-10-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | i think there is wasted space in allocated pages for request and response rings. The allocations are made with REQUEST_ENTRY_CNT + 1 and RESPONSE_ENTRY_CNT + 1, but they are set with 256 and 16. So we got more pages, which we dont use very much so eliminate them.
