The testcase itself is a few months old, and at least on my testing here it seemed to have worked recently ... (In reply to comment #3) > Is this a regression? The testcase itself is a few months old, and at least > on my testing here it seemed to have worked recently ... Test on commit 16b23af8d4f95c09d2bb650e85ecf8ed9e7c18d0, it works well. Ok, let's shrug this off as a fluke then. Please reopen if it shows up again. For verification please run the test a few times in a loop to make sure. Bisect shows: e9fea5747d2b3dbff47a8790c1cc4d7af80051d6 is the first bad commit commit e9fea5747d2b3dbff47a8790c1cc4d7af80051d6 Author: Naresh Kumar Kachhi <naresh.kumar.kachhi@intel.com> Date: Wed Mar 12 16:39:41 2014 +0530 drm/i915: wait for rings to become idle once disabled make sure we wait for rings to become idle once they are disabled. In case of timeout print an error message Signed-off-by: Naresh Kumar Kachhi <naresh.kumar.kachhi@intel.com> [danvet: Frob patch as suggested by Chris.] Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> First bad commit for what? The error message? (In reply to comment #7) > First bad commit for what? The error message? It's for printing error message, the error existed earlier. It looks like this error is earlier than e9fea5747d2b3dbff47a8790c1cc4d7af80051d6. I try to apply this patch on earlier commit and try to find any good commit, but patch fails. patching file drivers/gpu/drm/i915/i915_reg.h Hunk #1 FAILED at 748. Hunk #2 FAILED at 824. 2 out of 2 hunks FAILED -- saving rejects to file drivers/gpu/drm/i915/i915_reg.h.rej patching file drivers/gpu/drm/i915/intel_ringbuffer.c Hunk #1 FAILED at 444. 1 out of 1 hunk FAILED -- saving rejects to file drivers/gpu/drm/i915/intel_ringbuffer.c.rej patching file drivers/gpu/drm/i915/intel_ringbuffer.h Hunk #1 succeeded at 35 with fuzz 2 (offset 2 lines). So I am not sure it is regression. Closed after more than one year of inactivity. Feel free to reopen if needed. Thanks |
