* drm/radeon/kms/vm: fix possible bug in radeon_vm_bo_rmv()Sebastian Biemueller2012-02-291-1/+1
| | | | | | | | | | | | The bo is removed from the list at the top of radeon_vm_bo_rmv(), but then the list is used in radeon_vm_bo_update_pte() to look up the vm. remove the bo_list entry at the end of the function instead.

* | drm/i915: Remove use of the autoreported ringbuffer HEAD positionChris Wilson2012-02-271-13/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a revert of 6aa56062eaba67adfb247cded244fd877329588d. This was originally introduced to workaround reads of the ringbuffer registers returning 0 on SandyBridge causing hangs due to ringbuffer overflow. The root cause here was reads through the GT powerwell require the forcewake dance, something we only learnt of later. Now it appears that reading the reported head position from the HWS is returning garbage, leading once again to hangs. For example, on q35 the autoreported head reports: [ 217.975608] head now 00010000, actual 00010000 [ 436.725613] head now 00200000, actual 00200000 [ 462.956033] head now 00210000, actual 00210010 [ 485.501409] head now 00400000, actual 00400020 [ 508.064280] head now 00410000, actual 00410000 [ 530.576078] head now 00600000, actual 00600020 [ 553.273489] head now 00610000, actual 00610018 which appears reasonably sane. In contrast, if we look at snb: [ 141.970680] head now 00e10000, actual 00008238 [ 141.974062] head now 02734000, actual 000083c8 [ 141.974425] head now 00e10000, actual 00008488 [ 141.980374] head now 032b5000, actual 000088b8 [ 141.980885] head now 03271000, actual 00008950 [ 142.040628] head now 02101000, actual 00008b40 [ 142.180173] head now 02734000, actual 00009050 [ 142.181090] head now 00000000, actual 00000ae0 [ 142.183737] head now 02734000, actual 00009050 In addition, the automatic reporting of the head position is scheduled to be defeatured in the future. It has no more utility, remove it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With base on latest findings, RC6p seems to be respondible for RC6-related issues on Sandy Bridge platform. To work-around those issues, the previous solution was to completely disable RC6 on Sandy Bridge for the past few releases, even if plain RC6 was not giving any issues. What this patch does is preventing RC6p from being enabled on Sandy Bridge even if users enable RC6 via a kernel parameter. So it won't change the defaults in any way, but will ensure that if users do enable RC6 manually it won't break their machines by enabling this extra state. Proper fix for this (enabling specific RC6 states according to the GPU generation) were proposed for the -next kernel, but we are too late in the release process now to pick such changes.

This patch only supports 18bpp and 24bpp modes, which means that 10bpc modes will be computed incorrectly. Fixing that will require more extensive changes, and so must be addressed separately from this bugfix. intel_dp_link_required is called from intel_dp_mode_valid and intel_dp_mode_fixup. * intel_dp_mode_valid is called to list supported modes; in this case, the current crtc values cannot be relevant as the modes in question may never be selected. Thus, using intel_crtc->bpp is never right. * intel_dp_mode_fixup is called during mode setting, but it is run well before ironlake_crtc_mode_set is called to set intel_crtc->bpp, so using intel_crtc-bpp in this path can only ever get a stale value.

This should fix the issue reported by Alfonso Fiore where booting with only a HDMI cable connected to his TV failed to display anything. The issue is that the bios set up things for 1080i and used the pannel fitter to scale up the lower progressive resolutions. We failed to clear the interlace bit in the PIPEACONF register, resulting in havoc.

* | drm/radeon/kms/blit: fix blit copy for very large buffersIlija Hadzic2012-02-021-10/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Evergreen and NI blit copy was broken if the buffer maps to a rectangle whose one dimension is 16384 (max dimension allowed by these chips). In the mainline kernel, the problem is exposed only when buffers are very large (1G), but it's still a problem. The problem could be exposed for smaller buffers if anyone modifies the algorithm for rectangle construction in r600_blit_create_rect() (the reason why someone would modify that algorithm is to tune the performance of buffer moves). The root cause was in i2f() function which only operated on range between 0 and 16383. Fix this by extending the range of i2f() function to 0 to 32767. While at it improve the function so that the range can be easily extended in the future (if it becomes necessary), cleanup lines over 80 characters, and replace in-line comments with one strategic comment that explains the crux of the function. Credits to michel@daenzer.net for pointing out the root cause of the bug. v2: Fix I2F_MAX_INPUT constant definition goof and warn only once if input argument is out of range. Edit the comment a little bit to avoid some linguistic confusion and make it look better in general.

* | drm/radeon: Set DESKTOP_HEIGHT register to the framebuffer (not mode) height.Michel Dänzer2012-02-011-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The value of this register is transferred to the V_COUNTER register at the beginning of vertical blank. V_COUNTER is the reference for VLINE waits and goes from VIEWPORT_Y_START to VIEWPORT_Y_START+VIEWPORT_HEIGHT during scanout, so if VIEWPORT_Y_START is not 0, V_COUNTER actually went backwards at the beginning of vertical blank, and VLINE waits excluding the whole scanout area could never finish (possibly only if VIEWPORT_Y_START is larger than the length of vertical blank in scanlines). Setting DESKTOP_HEIGHT to the framebuffer height should prevent this for any kind of VLINE wait. Fixes https://bugs.freedesktop.org/show_bug.cgi?id=45329 .
