I suspect the delay is more likely due to the workqueue than the interrupt itself. Way back when I implemented DRI1 tear-free buffer swaps for i945, I had to use a tasklet to reliably do work within the vertical blank period. -- Earthling Michel Dänzer |http://www.vmware.com Libre software enthusiast | Debian, X and DRI developer -- This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev -- ___ Dri-devel mailing list Dri-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/dri-devel

It's not enabled at the moment as nothing uses it. You can set it to fire an interrupt at a particular vline during scanout. The info needed is in the r5xx and r6xx modesetting docs and in the reg headers and code in the driver. One possible problem is that we use the vline stuff (not the interrupt, just the vline) for Xv anti-tearing stuff, so you may run into issues there.

I remove DRM_INFOs and also moved radeon_get_power_state calls from IRQ handler to line before rdev->pm.vblank_callback = true;. This didn't help. I guess you may be right with this VBLANK.

drm/radeon/kms: pm: single frame corruptions on reclocking
I applied patches from http://www.botchco.com/alex/xorg/pm/ and now engine reclocks between 110MHz and 680MHz. The problem is I see ~10 black horizontal lines for a one frame time on almost every reclock. I tried to fix this or at least understand it somehow but without success. 1) Putting 500ms delay after every reclock doesn't improve anything 2) Reclocking between 110MHz and 130MHz (instead 680MHz) doesn't improve 3) Calling atombios_crtc_set_pll after reclocking doesn't improve 4) Calling ClockSource AtomBIOS commane after reclocking doesn't improve I tested 4th as SetEngineClock seems to play mostly with 0x0180 and ClockSource seems to be the only reading that register. Effects were horrible, don't ever call this AtomBIOS cammand ;) Do you have any other ideas? -- Rafał -- This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev -- ___ Dri-devel mailing list Dri-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/dri-devel

I just had to overhaul all of our mmap stuff and since I still only have 32 bits to work with on i386, I could only steal the upper 4 bits for a globally unique map id, which limits map size to 256MB. On amd64, I stole the upper 24 bits for the map id which still allows any single map to be up to 1TB in size. robert. > Luca -- Robert Noland 2Hip Networks -- This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev -- ___ Dri-devel mailing list Dri-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/dri-devel

This patch shouldn't cause issues, however I would personally really like to see drm_handle_t used consistently and correctly. If handle were declared as drm_handle_t it would avoid a lot of casting in libdrm and would have allowed me to reliably use arbitrary handles for maps on both i386 and amd64, by defining drm_handle_t to off_t.

RFC: radeon i2c algo
The attached set of patches adds an i2c algo for radeon hardware. It transparently supports bit-banging i2c on all asics and uses the hw i2c engine on supported asics (r1xx-r5xx right now, support for newer chips can be added later). For the bit banging, it encapsulates the gpio masking that needs to be done before using the lines, so i2c_transfer can be used directly and the buses can be used for other drivers like tuners, thermal chips, etc. I used i2c-bit-algo in the radeon i2c algo, is that kosher? It seems to make more sense than dragging i2c-bit-algo into the driver. Thoughts?
