2019-03-19drm/amdgpu: Set VM_L2_CNTL.PDE_FAULT_CLASSIFICATION to 0Yong Zhao
This is recommended by HW designers. Previously when it was set to 1, the PDE walk error in VM fault will be treated as PERMISSION_OR_INVALID_PAGE_FAULT rather than usually expected OTHER_FAULT. As a result, the retry control in VM_CONTEXT*_CNTL will change accordingly. The above behavior is kind of abnormal. Furthermore, the PDE_FAULT_CLASSIFICATION == 1 feature was targeted for very old ASICs and it never made it way to production. Therefore, we should set it to 0.

2019-03-19drm/amdgpu: replace get_user_pages with HMM mirror helpersPhilip Yang
Use HMM helper function hmm_vma_fault() to get physical pages backing userptr and start CPU page table update track of those pages. Then use hmm_vma_range_done() to check if those pages are updated before amdgpu_cs_submit for gfx or before user queues are resumed for kfd. If userptr pages are updated, for gfx, amdgpu_cs_ioctl will restart from scratch, for kfd, restore worker is rescheduled to retry. HMM simplify the CPU page table concurrent update check, so remove guptasklock, mmu_invalidations, last_set_pages fields from amdgpu_ttm_tt struct. HMM does not pin the page (increase page ref count), so remove related operations like release_pages(), put_page(), mark_page_dirty().

2019-03-19scsi: core: Avoid that a kernel warning appears during system resumeBart Van Assche
Since scsi_device_quiesce() skips SCSI devices that have another state than RUNNING, OFFLINE or TRANSPORT_OFFLINE, scsi_device_resume() should not complain about SCSI devices that have been skipped. Hence this patch. This patch avoids that the following warning appears during resume: WARNING: CPU: 3 PID: 1039 at blk_clear_pm_only+0x2a/0x30 CPU: 3 PID: 1039 Comm: kworker/u8:49 Not tainted 5.0.0+ #1 Hardware name: LENOVO 4180F42/4180F42, BIOS 83ET75WW (1.45 ) 05/10/2013 Workqueue: events_unbound async_run_entry_fn RIP: 0010:blk_clear_pm_only+0x2a/0x30 Call Trace: ? scsi_device_resume+0x28/0x50 ? scsi_dev_type_resume+0x2b/0x80 ? async_run_entry_fn+0x2c/0xd0 ? process_one_work+0x1f0/0x3f0 ? worker_thread+0x28/0x3c0 ? process_one_work+0x3f0/0x3f0 ? kthread+0x10c/0x130 ? __kthread_create_on_node+0x150/0x150 ? ret_from_fork+0x1f/0x30 Cc: Christoph Hellwig <hch@lst.de> Cc: Hannes Reinecke <hare@suse.com> Cc: Ming Lei <ming.lei@redhat.com> Cc: Johannes Thumshirn <jthumshirn@suse.de> Cc: Oleksandr Natalenko <oleksandr@natalenko.name> Cc: Martin Steigerwald <martin@lichtvoll.de> Cc: <stable@vger.kernel.org> Reported-by: Jisheng Zhang <Jisheng.Zhang@synaptics.com> Tested-by: Jisheng Zhang <Jisheng.Zhang@synaptics.com> Fixes: 3a0a529971ec ("block, scsi: Make SCSI quiesce and resume work reliably") # v4.15 Signed-off-by: Bart Van Assche <bvanassche@acm.org> Signed-off-by: Martin K.
