agp/intel: Fix a memory leak on module initialisation failure

2020-08-21T08:53:00Z

[ Upstream commit b975abbd382fe442713a4c233549abb90e57c22b ] In intel_gtt_setup_scratch_page(), pointer "page" is not released if pci_dma_mapping_error() return an error, leading to a memory leak on module initialisation failure. Simply fix this issue by freeing "page" before return.

agp/intel: Flush all chipset writes after updating the GGTT

2018-03-22T08:23:29Z

[ Upstream commit 8516673a996870ea0ceb337ee4f83c33c5ec3111 ] Before accessing the GGTT we must flush the PTE writes and make them visible to the chipset, or else the indirect access may end up in the wrong page. In commit 3497971a71d8 ("agp/intel: Flush chipset writes after updating a single PTE"), we noticed corruption of the uploads for pwrite and for capturing GPU error states, but it was presumed that the explicit calls to intel_gtt_chipset_flush() were sufficient for the execbuffer path. However, we have not been flushing the chipset between the PTE writes and access via the GTT itself. For simplicity, do the flush after any PTE update rather than try and batch the flushes on a just-in-time basis.

Merge tag 'drm-intel-fixes-2015-07-15' into drm-intel-next-queued

2015-07-15T14:36:50Z

Backmerge fixes since it's getting out of hand again with the massive split due to atomic between -next and 4.2-rc. All the bugfixes in 4.2-rc are addressed already (by converting more towards atomic instead of minimal duct-tape) so just always pick the version in next for the conflicts in modeset code. All the other conflicts are just adjacent lines changed.

agp/intel: Fix typo in needs_ilk_vtd_wa()

2015-06-29T11:26:09Z

In needs_ilk_vtd_wa(), we pass in the GPU device but compared it against the ids for the mobile GPU and the mobile host bridge. That latter is impossible and so likely was just a typo for the desktop GPU device id (which is also buggy).
