It's simply that "the lighter memory stress, the bigger object retain rate". The piglit case is attached for review. According to the testing result of this case, it's working well. Also do you have plan or comment on test cases I sent out, or for those bugs I reported for this feature? <table class="bz_buglist" width="100%" cellpadding="4" cellspacing="0"> <tbody> <tr class="bz_bugitem bz_normal bz_medium bz_NEW bz_row_odd "> <td class="first-child"><a name="b26126" href="https://bugs.freedesktop.org/show_bug.cgi?id=26126">26126</a> </td> <td style="white-space: nowrap;">nor </td> <td style="white-space: nowrap;">med </td> <td style="white-space: nowrap;"><a class="moz-txt-link-abbreviated" href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a> </td> <td style="white-space: nowrap;">NEW </td> <td style="white-space: nowrap;"> </td> <td style="white-space: nowrap;">Linu </td> <td> </td> <td>[APPLE_object_purgeable] is not working with VBO </td> </tr> <tr class="bz_bugitem bz_normal bz_medium bz_NEW bz_row_even "> <td class="first-child"> <a name="b26127" href="https://bugs.freedesktop.org/show_bug.cgi?id=26127">26127</a> </td> <td style="white-space: nowrap;">nor </td> <td style="white-space: nowrap;">med </td> <td style="white-space: nowrap;"><a class="moz-txt-link-abbreviated" href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a> </td> <td style="white-space: nowrap;">NEW </td> <td style="white-space: nowrap;"> </td> <td style="white-space: nowrap;">Linu </td> <td> </td> <td>[APPLE_object_purgeable] is not working with PBO </td> </tr> <tr class="bz_bugitem bz_normal bz_medium bz_NEW bz_row_odd "> <td class="first-child"> <a name="b26128" href="https://bugs.freedesktop.org/show_bug.cgi?id=26128">26128</a> </td> <td style="white-space: nowrap;">nor </td> <td style="white-space: nowrap;">med </td> <td style="white-space: nowrap;"><a class="moz-txt-link-abbreviated" href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a> </td> <td style="white-space: nowrap;">NEW </td> <td style="white-space: nowrap;"> </td> <td style="white-space: nowrap;">Linu </td> <td> </td> <td>[APPLE_object_purgeable] Purgeable(VOLATILE) should always return VOLATILE </td> </tr> <tr class="bz_bugitem bz_normal bz_medium bz_NEW bz_row_even "> <td class="first-child"> <a name="b26129" href="https://bugs.freedesktop.org/show_bug.cgi?id=26129">26129</a> </td> <td style="white-space: nowrap;">nor </td> <td style="white-space: nowrap;">med </td> <td style="white-space: nowrap;"><a class="moz-txt-link-abbreviated" href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a> </td> <td style="white-space: nowrap;">NEW </td> <td style="white-space: nowrap;"> </td> <td style="white-space: nowrap;">Linu </td> <td> </td> <td>[APPLE_object_purgeable] error should be generated when purgeable/unpurgeable called between Begin()/End() </td> </tr> </tbody> </table> The test case for performance testing is still under design.
