(He Shuang on behalf of Liu Lei) Tested-by: Lei,Liu lei.a.liu@intel.com I-G-T test result: ./pm_sseu IGT-Version: 1.9-g07be8fe (x86_64) (Linux: 4.0.0-rc3_drm-intel-nightly_c09a3b_20150310+ x86_64) Subtest full-enable: SUCCESS (0.010s) Manually test result: SSEU Device Info Available Slice Total: 1 Available Subslice Total: 3 Available Subslice Per Slice: 3 Available EU Total: 23 Available EU Per Subslice: 8 Has Slice Power Gating: no Has Subslice Power Gating: no Has EU Power Gating: yes SSEU Device Status Enabled Slice Total: 1 Enabled Subslice Total: 3 Enabled Subslice Per Slice: 3 Enabled EU Total: 24 Enabled EU Per Subslice: 8 EU are enabled in pairs. Because one EU in a pair can be fused-off, it is possible to see such case where reported EU enabled is greater than reported EU available. The IGT test allows for this discrepancy and only fails if enabled is less than available, which can only happen if unwanted power gating is applied Best wishes Liu,Lei > -----Original Message----- > From: Intel-gfx [mailto:intel-gfx-bounces@lists.freedesktop.org] On Behalf > Of jeff.mcgee@intel.com > Sent: Friday, March 13, 2015 1:52 AM > To: intel-gfx@lists.freedesktop.org > Subject: [Intel-gfx] [PATCH i-g-t 1/2 v2] lib: Add media spin > > From: Jeff McGee <jeff.mcgee@intel.com> > > The media spin utility is derived from media fill.

Because one EU in a pair can be fused-off, it is possible to see such case where reported EU enabled is greater than reported EU available. The IGT test allows for this discrepancy and only fails if enabled is less than available, which can only happen if unwanted power gating is applied > > Best wishes > Liu,Lei > >> -----Original Message----- >> From: Intel-gfx [mailto:intel-gfx-bounces@lists.freedesktop.org] On Behalf >> Of jeff.mcgee@intel.com >> Sent: Friday, March 13, 2015 1:52 AM >> To: intel-gfx@lists.freedesktop.org >> Subject: [Intel-gfx] [PATCH i-g-t 1/2 v2] lib: Add media spin >> >> From: Jeff McGee <jeff.mcgee@intel.com> >> >> The media spin utility is derived from media fill.
