2013-08-07drm/mgag200: Invalidate page tables when pinning a BOEgbert Eich
When a BO gets pinned the placement may get changed. If the memory is mapped into user space and user space has already accessed the mapped range the page tables are set up but now point to the wrong memory. Set bo.mdev->dev_mapping in mgag200_bo_create() to make sure that ttm_bo_unmap_virtual() called from ttm_bo_handle_move_mem() will take care of this. v2: Don't call ttm_bo_unmap_virtual() in mgag200_bo_pin(), fix comment.

The problem is, drm_mode_config_cleanup crashes because the corresponding init hasn't happend yet.

2013-06-17drm/mgag200: Hardware cursor supportChristopher Harvey
G200 cards support, at best, 16 colour palleted images for the cursor so we do a conversion in the cursor_set function, and reject cursors with more than 16 colours, or cursors with partial transparency. Xorg falls back gracefully to software cursors in this case. We can't disable/enable the cursor hardware without causing momentary corruption around the cursor. Instead, once the cursor is on we leave it on, and simulate turning the cursor off by moving it offscreen. This works well. Since we can't disable -> update -> enable the cursors, we double buffer cursor icons, then just move the base address that points to the old cursor, to the new. This also works well, but uses an extra page of memory. The cursor buffers are lazily-allocated on first cursor_set. This is to make sure they don't take priority over any framebuffers in case of limited memory. Here is a representation of how the bitmap for the cursor is mapped in G200 memory : Each line of color cursor use 6 Slices of 8 bytes. Slices 0 to 3 are used for the 4bpp bitmap, slice 4 for XOR mask and slice 5 for AND mask. Each line has the following format: // Byte 0 Byte 1 Byte 2 Byte 3 Byte 4 Byte 5 Byte 6 Byte 7 // // S0: P00-01 P02-03 P04-05 P06-07 P08-09 P10-11 P12-13 P14-15 // S1: P16-17 P18-19 P20-21 P22-23 P24-25 P26-27 P28-29 P30-31 // S2: P32-33 P34-35 P36-37 P38-39 P40-41 P42-43 P44-45 P46-47 // S3: P48-49 P50-51 P52-53 P54-55 P56-57 P58-59 P60-61 P62-63 // S4: X63-56 X55-48 X47-40 X39-32 X31-24 X23-16 X15-08 X07-00 // S5: A63-56 A55-48 A47-40 A39-32 A31-24 A23-16 A15-08 A07-00 // // S0 to S5 = Slices 0 to 5 // P00 to P63 = Bitmap - pixels 0 to 63 // X00 to X63 = always 0 - pixels 0 to 63 // A00 to A63 = transparent markers - pixels 0 to 63 // 1 means colour, 0 means transparent Signed-off-by: Christopher Harvey <charvey@matrox.com> Signed-off-by: Mathieu Larouche <mathieu.larouche@matrox.com> Acked-by: Julia Lemire <jlemire@matrox.com> Tested-by: Julia Lemire <jlemire@matrox.com> Signed-off-by: Dave Airlie <airlied@gmail.com>

The original line, WREG_DAC(MGA1064_PIX_CLK_CTL_CLK_DIS, tmp); wrote tmp into MGA1064_PIX_CLK_CTL_CLK_DIS, where MGA1064_PIX_CLK_CTL_CLK_DIS is an offset into MGA1064_PIX_CLK_CTL. Change the line to write properly into MGA1064_PIX_CLK_CTL. There were other chunks of code nearby that use the same pattern (but work correctly), so this patch updates them all to use this new (slightly more efficient) write pattern. The WREG_DAC macro was causing the DAC_INDEX register to be set to the same value twice. WREG8(DAC_DATA, foo) takes advantage of the fact that DAC_INDEX is already at the value we want.

2013-03-21drm/mgag200: Bug fix: Modified pll algorithm for EH projectJulia Lemire
While testing the mgag200 kms driver on the HP ProLiant Gen8, a bug was seen. Once the bootloader would load the selected kernel, the screen would go black. At first it was assumed that the mgag200 kms driver was hanging. But after setting up the grub serial output, it was seen that the driver was being loaded properly. After trying serval monitors, one finaly displayed the message "Frequency Out of Range". By comparing the kms pll algorithm with the previous mgag200 xorg driver pll algorithm, discrepencies were found. Once the kms pll algorithm was modified, the expected pll values were produced. This fix was tested on several monitors of varying native resolutions. Signed-off-by: Julia Lemire <jlemire@matrox.com> Cc: stable@vger.kernel.org Signed-off-by: Dave Airlie <airlied@redhat.com>
2013-03-07drm/mgag200: Bug fix: Renesas board now selects native resolution.Julia Lemire
Renesas boards were consistently defaulting to the 1024x768 resolution, regardless of the native resolution of the monitor plugged in. It was determined that the EDID of the monitor was not being read. Since the DAC is a shared line, in order to read from or write to it we must take control of the DAC clock. This can be done by setting the proper register to one. This bug fix sets the register MGA1064_GEN_IO_CTL2 to one. The DAC control line can be used to determine whether or not a new monitor has been plugged in. But since the hotplug feature is not one we will support, it has been decided to simply leave the register set to one.

2013-01-20drm: revamp framebuffer cleanup interfacesDaniel Vetter
We have two classes of framebuffer - Created by the driver (atm only for fbdev), and the driver holds onto the last reference count until destruction. - Created by userspace and associated with a given fd. These framebuffers will be reaped when their assoiciated fb is closed. Now these two cases are set up differently, the framebuffers are on different lists and hence destruction needs to clean up different things. Also, for userspace framebuffers we remove them from any current usage, whereas for internal framebuffers it is assumed that the driver has done this already. Long story short, we need two different ways to cleanup such drivers. Three functions are involved in total: - drm_framebuffer_remove: Convenience function which removes the fb from all active usage and then drops the passed-in reference. - drm_framebuffer_unregister_private: Will remove driver-private framebuffers from relevant lists and drop the corresponding references. Should be called for driver-private framebuffers before dropping the last reference (or like for a lot of the drivers where the fbdev is embedded someplace else, before doing the cleanup manually). - drm_framebuffer_cleanup: Final cleanup for both classes of fbs, should be called by the driver's ->destroy callback once the last reference is gone. This patch just rolls out the new interfaces and updates all drivers (by adding calls to drm_framebuffer_unregister_private at all the right places)- no functional changes yet. Follow-on patches will move drm core code around and update the lifetime management for framebuffers, so that we are no longer required to keep framebuffers alive by locking mode_config.mutex. I've also updated the kerneldoc already. vmwgfx seems to again be a bit special, at least I haven't figured out how the fbdev support in that driver works. It smells like it's external though. v2: The i915 driver creates another private framebuffer in the load-detect code. Adjust its cleanup code, too.

2013-01-20drm/<drivers>: Unified handling of unimplemented fb->create_handleDaniel Vetter
Some drivers don't have real ->create_handle callbacks. - cirrus/ast/mga200: Returns either 0 or -EINVAL. - udl: Didn't even bother with a callback, leading to a nice userspace-triggerable OOPS. - vmwgfx: This driver bothered with an implementation to return 0 as the handle (which is the canonical no-obj gem handle). All have in common that ->create_handle doesn't really make too much sense for them - that ioctl is used only for seamless fb takeover in the radeon/nouveau/i915 ddx drivers. So allow drivers to not implement this and return a consistent -ENODEV. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2013-01-20drm/<drivers>: reorder framebuffer init sequenceDaniel Vetter
With more fine-grained locking we can no longer rely on the big mode_config lock to prevent concurrent access to mode resources like framebuffers. Instead a framebuffer becomes accessible to other threads as soon as it is added to the relevant lookup structures. Hence it needs to be fully set up by the time drivers call drm_framebuffer_init. This patch here is the drivers part of that reorg. Nothing really fancy going on safe for three special cases. - exynos needs to be careful to properly unref all handles. - nouveau gets a resource leak fixed for free: one of the error cases didn't cleanup the framebuffer, which is now moot since the framebuffer is only registered once it is fully set up. - vmwgfx requires a slight reordering of operations, I'm hoping I didn't break anything (but it's refcount management only, so should be safe). v2: Split out exynos, since it's a bit more hairy than expected. v3: Drop bogus cirrus hunk noticed by Richard Wilbur. v4: Split out vmwgfx since there's a small change in return values.

2012-10-04Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linuxLinus Torvalds
Pull drm merge (part 1) from Dave Airlie: "So first of all my tree and uapi stuff has a conflict mess, its my fault as the nouveau stuff didn't hit -next as were trying to rebase regressions out of it before we merged. Highlights: - SH mobile modesetting driver and associated helpers - some DRM core documentation - i915 modesetting rework, haswell hdmi, haswell and vlv fixes, write combined pte writing, ilk rc6 support, - nouveau: major driver rework into a hw core driver, makes features like SLI a lot saner to implement, - psb: add eDP/DP support for Cedarview - radeon: 2 layer page tables, async VM pte updates, better PLL selection for > 2 screens, better ACPI interactions The rest is general grab bag of fixes. So why part 1? well I have the exynos pull req which came in a bit late but was waiting for me to do something they shouldn't have and it looks fairly safe, and David Howells has some more header cleanups he'd like me to pull, that seem like a good idea, but I'd like to get this merge out of the way so -next dosen't get blocked." Tons of conflicts mostly due to silly include line changes, but mostly mindless. A few other small semantic conflicts too, noted from Dave's pre-merged branch. * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (447 commits) drm/nv98/crypt: fix fuc build with latest envyas drm/nouveau/devinit: fixup various issues with subdev ctor/init ordering drm/nv41/vm: fix and enable use of "real" pciegart drm/nv44/vm: fix and enable use of "real" pciegart drm/nv04/dmaobj: fixup vm target handling in preparation for nv4x pcie drm/nouveau: store supported dma mask in vmmgr drm/nvc0/ibus: initial implementation of subdev drm/nouveau/therm: add support for fan-control modes drm/nouveau/hwmon: rename pwm0* to pmw1* to follow hwmon's rules drm/nouveau/therm: calculate the pwm divisor on nv50+ drm/nouveau/fan: rewrite the fan tachometer driver to get more precision, faster drm/nouveau/therm: move thermal-related functions to the therm subdev drm/nouveau/bios: parse the pwm divisor from the perf table drm/nouveau/therm: use the EXTDEV table to detect i2c monitoring devices drm/nouveau/therm: rework thermal table parsing drm/nouveau/gpio: expose the PWM/TOGGLE parameter found in the gpio vbios table drm/nouveau: fix pm initialization order drm/nouveau/bios: check that fixed tvdac gpio data is valid before using it drm/nouveau: log channel debug/error messages from client object rather than drm client drm/nouveau: have drm debugging macros build on top of core macros ...

2012-10-02UAPI: (Scripted) Remove redundant DRM UAPI header #inclusions from drivers/gpu/.David Howells
Remove redundant DRM UAPI header #inclusions from drivers/gpu/. Remove redundant #inclusions of core DRM UAPI headers (drm.h, drm_mode.h and drm_sarea.h). They are now #included via drmP.h and drm_crtc.h via a preceding patch. Without this patch and the patch to make include the UAPI headers from the core headers, after the UAPI split, the DRM C sources cannot find these UAPI headers because the DRM code relies on specific -I flags to make #include "..." work on headers in include/drm/ - but that does not work after the UAPI split without adding more -I flags.

2012-09-24Merge tag 'v3.6-rc7' into drm-intel-next-queuedDaniel Vetter
Manual backmerge of -rc7 to resolve a silent conflict leading to compile failure in drivers/gpu/drm/i915/intel_hdmi.c. This is due to the bugfix in -rc7: commit b98b60167279df3acac9422c3c9820d9ebbcf9fb Author: Wang Xingchao <xingchao.wang@intel.com> Date: Thu Sep 13 07:43:22 2012 +0800 drm/i915: HDMI - Clear Audio Enable bit for Hot Plug Since this code moved around a lot in -next git put that snippet at the wrong spot. I've tried to fix this by making the conflict explicit by merging a version for next with: commit 3cce574f0190dd149472059fb69267cf83d290f9 Author: Wang Xingchao <xingchao.wang@intel.com> Date: Thu Sep 13 11:19:00 2012 +0800 drm/i915: HDMI - Clear Audio Enable bit for Hot Plug unconditionally But that failed to solve the entire problem. To avoid pushing out further -nightly branch to our QA where this is broken, do the backmerge and manually add the stuff git adds to -next from the patch in -fixes. Note that this doesn't show up in git's merge diff (and hence is also not handled by git rerere), which adds to the reasons why I'd like to fix this with a verbose backmerge. The git merge diff only shows a bunch of trivial conflicts of the "code changed in lines next to each another" kind. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2012-09-05drm: use drm_compat_ioctl for 32-bit appsKeith Packard
Most of the DRM drivers appear to be missing the .compat_ioctl file operation entry necessary for 32-bit application compatibility. This patch uses drm_compat_ioctl for all drivers which don't have their own, and which are using drm_ioctl for .unlocked_ioctl. This leaves drivers/gpu/drm/psb/psb_drv.c unchanged; it has a custom .unlocked_ioctl and will presumably need a custom .compat_ioctl as well.

2012-08-23drm: remove the raw_edid field from struct drm_display_infoJani Nikula
Neither the drm core nor any of the drivers really need the raw_edid field of struct drm_display_info for anything. Instead of being useful, it creates confusion about who is responsible for freeing the memory it points to and setting the field to NULL afterwards, leading to memory leaks and dangling pointers. Remove the raw_edid field, and fix drivers as necessary.
