* drm/i915/gvt: add a NULL pointer check to avoid kernel panicChuanxiao Dong2017-02-231-0/+3
| | | | | | | | | | | | | | | | Due to the request replay, context switch interrupt may come after gvt free the workload thus can cause a kernel NULL pointer kernel panic. This patch will add a simple check to avoid this for a short term. From long term, gvt workload lifecycle doesn't match with i915 request and need to find a proper way to manage this. v4: simplify the NULL pointer check. v5: add unlikely to optimize.

| | | | | | | | | | | Windows guest will notitfy GVT-g to request more resources through g2v interface, when its resources are not enough. This patch is to handle this case and let vgpu enter failsafe mode to avoid too many error messages.

| | | | | | | | | | | | | | Lots of reduntant log info will be printed out during GPU reset, including accessing untracked mmio register and fence register, variable disable_warn_untrack is added previously to handle the situation, but the accessing of fence register is ignored in the previously patch, so add it back.

* drm/i915/gvt: introduced failsafe mode into vgpuMin He2017-02-175-1/+112
| | | | | | | | | | | | | | | | | | | | New failsafe mode is introduced, when we detect guest not supporting GVT-g. In failsafe mode, we will ignore all the MMIO and cfg space read/write from guest. This patch can fix the issue that when guest kernel or graphics driver version is too low, there will be a lot of kernel traces in host. V5: rebased onto latest gvt-staging V4: changed coding style by Zhenyu and Ping's advice V3: modified coding style and error messages according to Zhenyu's comment V2: 1) implemented MMIO/GTT/WP pages read/write logic; 2) used a unified function to enter failsafe mode Signed-off-by: Min He <min.he@intel.com> Signed-off-by: Pei Zhang <pei.zhang@intel.com> Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com>

| | | | | | | | | | | | | | | | | MFN usually refers to "Machine Frame Number" in virtulization world. Currently GVT-g populates the shadow PPGTT/GGTT page table with MFN according to the translation between MFN and Guest PFN. When host IOMMU is enabled, GPU DMA transactions go through the IOMMU, GPU needs an IOVA<->MFN mapping to walk the shadow page table in host main memory. This patch will map a page in IOMMU page table before using it in shadow page table and release the map when a shadow page is going to be freed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The size computations done in the ioctl function use an integer. If userspace submits a request with req->cmd_nr or req->cmd_buf_nr set to INT_MAX, the integer computations overflow later, leading to potential (kernel) memory corruption. Prevent this issue by enforcing a limit on the number of submitted commands, so that we have enough headroom later for the size computations. Note that this change has no impact on the currently available users in userspace, like e.g. libdrm/exynos. While at it, also make a comment about the size computation more detailed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch replaces specific atomic commit function with atomic helper commit one. For this, it removes existing atomic commit function and relevant code specific to Exynos DRM and makes atomic helper commit to be used instead. Below are changes for the use of atomic helper commit: - add atomic_commit_tail callback specific to Exynos DRM . default implemention of atomic helper doesn't mesh well with runtime PM so the device driver which supports runtime PM should call drm_atomic_helper_commit_modeset_enables function prior to drm_atomic_helper_commit_planes function call. atomic_commit_tail callback implements this call ordering. - allow plane commit only in case that CRTC device is enabled. . for this, it calls atomic_helper_commit_planes function with DRM_PLANE_COMMIT_ACTIVE_ONLY flag in atomic_commit_tail callback.
