2020-11-26drm/i915/display: Defer initial modeset until after GGTT is initialisedChris Wilson1-10/+10
Prior to sanitizing the GGTT, the only operations allowed in intel_display_init_nogem() are those to reserve the preallocated (and active) regions in the GGTT leftover from the BIOS. Trying to allocate a GGTT vma (such as intel_pin_and_fence_fb_obj during the initial modeset) may then conflict with other preallocated regions that have not yet been protected. Move the initial modesetting from the end of init_nogem to the beginning of init so that any vma pinning (either framebuffers or DSB, for example), is after the GGTT is ready to handle it. This will prevent the DSB object from being destroyed too early: [ 53.449241] BUG: KASAN: use-after-free in i915_init_ggtt+0x324/0x9e0 [i915] [ 53.449309] Read of size 8 at addr ffff88811b1e8070 by

2020-11-23drm/i915/gvt: treat intel_gvt_mpt as const in gvt codeJulian Stecklina4-4/+4
The current interface of intel_gvt_register_hypervisor() expects a non-const pointer to struct intel_gvt_mpt, even though the mediator never modifies (or should modifiy) the content of this struct. Change the function signature and relevant struct members to const to properly express the API's intent and allow instances of intel_gvt_mpt to be allocated as const. While I was here, I also made KVM's instance of this struct const to reduce the number of writable function pointers in the kernel.

2020-11-20drm/i915/dg1: Enable portsAditya Swarup1-4/+4
For DG1 we have a little of mix up wrt to DDI/port names and indexes. Bspec refers to the ports as DDIA, DDIB, DDI USBC1 and DDI USBC2 (besides the DDIA, DDIB, DDIC, DDID), but the previous naming is the most unambiguous one. This means that for any register on Display Engine we should use the index of A, B, D and E. However in some places this is not true: - VBT: uses C and D and have to be mapped to D/E - IO/Combo: uses C and D, but we already differentiate those when we created the phy vs port distinction. This additional mapping for VBT and phy are already covered in previous patches, so now we can initialize all the DDIs as A, B, D and E. v2: Squash previous patch enabling just ports A and B since most of the pumbling code is already merged now Cc: Matt Roper <matthew.d.roper@intel.com> Cc: Clinton Taylor <Clinton.A.Taylor@intel.com> Signed-off-by: Aditya Swarup <aditya.swarup@intel.com> Reviewed-by: Lucas De Marchi <lucas.demarchi@intel.com> Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20201117084836.2318234-1-lucas.demarchi@intel.com

2020-11-19drm/i915/perf: workaround register corruption in OATAILPTRLionel Landwerlin2-2/+9
After having written the entire OA buffer with reports, the HW will write again at the beginning of the OA buffer. It'll indicate it by setting the WRAP bits in the OASTATUS register. When a wrap happens and that at the end of the read vfunc we write the OASTATUS register back to clear the REPORT_LOST bit, we sometimes see that the OATAILPTR register is reset to a previous position on Gen8/9 (apparently not the case on Gen11+). This leads the next call to the read vfunc to process reports we've already read. Because we've marked those as read by clearing the reason & timestamp dwords, they're discarded and a "Skipping spurious, invalid OA report" message is emitted. The workaround to avoid this OATAILPTR value reset seems to be to set the wrap bits when writing back OASTATUS. This change has no impact on userspace, it only avoids a bunch of DRM_NOTE("Skipping spurious, invalid OA report\n") messages.
