With the previous change, it's safe to let page flips take effect anytime during a vertical blank period. This can avoid delaying a flip by a frame in some cases where we get to radeon_flip_work_func -> adev->mode_info.funcs->page_flip during a vertical blank period. Acked-by:

Now we can program a flip during a vertical blank period, if it's the one targeted by the flip (or a later one). This allows simplifying radeon_flip_work_func considerably. Acked-by:

Mostly the same as the existing page_flip hook, but takes an additional parameter specifying the target vertical blank period when the flip should take effect. v2: * Add curly braces around else statement corresponding to an if block with curly braces (Alex Deucher) * Call drm_crtc_vblank_put in the error case (Daniel Vetter) * Clarify entry point documentation comment (Daniel Vetter) Acked-by:

We align to 64KB, but when userspace aligns even more we can easily use more. Signed-off-by:

We can add the fragment params before we split the update for the page tables. That should save a few CPU cycles for larger updates. Signed-off-by:

No need to carry that forward as a separate parameter. Signed-off-by:

Well those are actually page table entry parameters. This also makes the variable names used a bit shorter. Signed-off-by:

We can actually do way more than just the 64KB we currently used as default. Signed-off-by:

This patch introduces a new macro WREG32_FIELD which is used to write to a register with a new value in a field. It's designed to replace the pattern: tmp = RREG32(mmFoo); tmp &= ~REG__FIELD_MASK; tmp |= new_value << REG__FIELD__SHIFT; WREG32(mmFoo, tmp) with: WREG32_FIELD(Foo, FIELD, new_value); Unlike WREG32_P() it understands offsets/masks and doesn't require the caller to shift the value (or mask properly). It's applied where suitable in the gfx_v8_0.c driver to start with. Signed-off-by:

For virtual display feature, as there may be multiple GPUs, for user could choose whiche GPU need to enable this feature, change the type of virtual_display from int to char*. The variable will be set like this virtual_display="xxxx:xx:xx.x;xxxx:xx:xx.x;". Signed-off-by:

For virtual display feature, initialize dce_virtual_crtc_irq_funcs, dce_virtual_pageflip_irq_funcs. As it has no dce engine, so the pageflip interrupt won't be generated, and the vsync interrupt will be generated by smu's periodic timer or software timer which will be implemented later. v2: agd: rebase on upstream Signed-off-by:

When this code was written, we didn't retry DP aux transactions on any error, which required retrying important transactions like this in individual drivers. Since that's no longer the case, retrying here is not necessary. As well, we retry any aux transaction on any error 32 times. 7 * 32 = 224, which means this loop causes us to retry grabbing the dpcd 224 times. This is definitely far more then we actually need to do. Reviewed-by:

Since it's normal for DRM to retry our aux transaction helpers multiple times in a row, up to 32 times for each attempted transaction, we're making a lot of noise that is no longer necessary now that DRM will just print the return code we give it. Reviewed-by:
