Eric suggested that unless we have evidence that the new work-around fixes bugs on SNB, that we should continue to use the HWSTAM work-around on that chip and use the RC6 voodoo on IVB, thus not potentially causing regressions on SNB. For back-porting to older kernels, that's obviously the right plan. I think it's also the right plan for newer kernels, but I'd love to hear alternate views on the matter. =2D-=20 keith.packard@intel.com --=-=-= Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIVAwUBTwtjjzYtFsjWk68qAQjKuQ/9EXA+bdPeLhSOFXpR0Gj8Jte93o6ckz3v RJ1tDa+jHWfiZ3CDt86R6H/2Mr4Z5TxV3CtFm/8+XvjQ2W5yPNvHgOod8efJ+pkc z9cheXJfg3Xu3sJi/i5/Ot65DxVrKiQGXo2FHq8ZWVSrTkXPhmUNPzwV3rTTSv3S RUBdOF8oLH1trCDtuXGKvxC0wJjhJlxuvxsVO1Th3MZK0P8nMWEB+DTtpaFCsUJ/ dlgppNcBEHZ8G7YSPRy3SxTfDf45ZXwFPG16Rbp3uq+Z4R3lJDsYAZF6s53VD61o +bPUQLFtCofrwYOn23Qy1J+o+JtMajMrZYuxeJEBwVYA8WIlmULd59kLcmW1GN0V iTdmU6zKtoS91uWCS32VKK7m8kqmSeMlT8ldJYf6SVOhyMZ5DpyGKKatRv9dfKV8 gAalnrVYPfmA4vTUaAgDit3RXcf0uzcoMJ3bv/pWnwTjz+sOeWRO9d6KL16Yhxdx xP3ZG2f8EtezXLoHQC/PnVS1ydav0ODjqP/LisH1QcXVQ0ePx5Fpyvb5YuTrUeBu DblSek18BoomqF/JAJ/9I/LTeULzdUqGyLD5ndccMnanBm/Xe88NI4PATlOrJmvV tYtosrfzl8IGqqfe3vfku++C8Mwi77njYDipQ4jNQGeXSOgn93gs0W62YvYM9OY2 eJtIIS31Z18= =Rf5u -----END PGP SIGNATURE----- --=-=-=-- --===============1734663618== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx --===============1734663618==--
