* drm/radeon: add 2-level VM pagetables support v9Dmitry Cherkasov2012-09-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PDE/PTE update code uses CP ring for memory writes. All page table entries are preallocated for now in alloc_pt(). It is made as whole because it's hard to divide it to several patches that compile and doesn't break anything being applied separately. Tested on cayman card. v2: rebased on top of "refactor set_page chipset interface v3", code cleanups v3: switched offsets calc macros to inline funcs where possible, remove pd_addr from radeon_vm, switched RADEON_BLOCK_SIZE define, to 9 (and PTE_COUNT to 1 << BLOCK_SIZE) v4 (ck): move "incr" documentation to previous patch, cleanup and document RADEON_VM_* constants, change commit message to our usual format, simplify patch allot by removing everything current not necessary, disable SI workaround. v5: (agd5f): Fix typo in tables_size calculation in radeon_vm_alloc_pt(). Second line should have been '+=' rather than '='. v6: fix npdes calculation. In scenario when pfns to be mapped overlap two PDE spans: +-----------+-------------+ | PDE span | PDE span | +-----------+----+--------+ | | +---------+ | pfns | +---------+ the following npdes calculation gives incorrect result: npdes = (nptes >> RADEON_VM_BLOCK_SIZE) + 1; For the case above picture it should give npdes = 2, but gives one. This patch corrects it by rounding last pfn up to 512 border, first - down to 512 border and then subtracting and dividing by 512. v7: Make npde calculation clearer, fix ndw calculation. v8: (agd5f): reserve enough for 2 full VM PTs, add some additional comments. v9: fix typo in npde calculation Signed-off-by: Dmitry Cherkasov <Dmitrii.Cherkasov@amd.com> Signed-off-by: Christian König <deathsimple@vodafone.de> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

* drm/radeon: work around KMS modeset limitations in PLL allocation (v2)Alex Deucher2012-09-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the current KMS API sets the mode independantly on each crtc, we may end up with resource conflicts. The PLL allocation is one of those cases. In the following example we have 3 crtcs in use driving 2 DVI connectors and 1 DP connector. On the initial kernel modeset for fbdev, the display topology ends up as follows: crtc0 -> DP-0 crtc1 -> DVI-0 crtc2 -> DVI-1 Because this is the first modeset, all of the PLLs are available as none have been assigned. So we end up with the following: crtc0 uses DCPLL crtc1 uses PPLL2 crtc2 uses PPLL1 When X starts, it assigns a different topology: crtc0 -> DVI-0 crtc1 -> DP-0 crtc2 -> DVI-1 However, since the KMS API is per crtc, we set the mode on each crtc independantly. When it comes time to set the mode on crtc0, the topology for crtc1 and crtc2 are still intact. crtc1 and crtc2 are already assigned PPLL2 and PPLL1 so when it comes time to set the mode on crtc0, crtc1 and crtc2 have not been torn down yet, so there appears to be no PLLs available. In reality, we are reconfiguring the entire display topology, however, since each crtc is handled independantly, we don't know that in the driver at each crtc mode set time. This patch checks to see if the same connector is being driven by another crtc, and if so, uses the PLL already associated with it. v2: store connector in the radeon crtc struct, simplify checking.

* drm/radeon: rework crtc pll setup to better support PPLL sharingAlex Deucher2012-09-20

* drm/radeon: allow PPLL sharing on non-DP displaysAlex Deucher2012-09-20
| | | | | | | | | | | | | | | | | | If several non-DP displays use the same pixel clock we can use the same PPLL for all of them. If all relevant displays have the same pixel clock, this allows the driver to: - use fewer PPLLs which saves power - support more than two non-DP displays on DCE4+ The current drm modesetting infrastructure doesn't really provide a good framework for validating combinations that work or won't work, so it's possible you could go from a working configuration to a non-working one by changing the mode a one of the displays. However, there this is better than what was there before. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

* drm/radeon: rework pll selection (v4)Alex Deucher2012-09-20
| | | | | | | | | | | | | | | | | | | | | For DP we can use the same PPLL for all active DP encoders. Take advantage of that to prevent cases where we may end up sharing a PPLL between DP and non-DP which won't work. Also clean up the code a bit. v2: - fix missing pll_id assignment in crtc init v3: - fix DP PPLL check - document functions - break in main encoder search loop after matching. no need to keep checking additional encoders. v4: - same as v3, but re-apply to drm-next as the corner cases are fixed properly in subsequent patches. fixes: https://bugs.freedesktop.org/show_bug.cgi?id=54471 Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
