      drm: don't drop handle reference on unload · dab8dcfa
      Dave Airlie 提交于
      since the handle references are all tied to a file_priv, and when it disappears
      all the handle refs go with it.
      
      The fbcon ones we'd only notice on unload, but the nouveau notifier one
      would would happen on reboot.

      drm/gem: handlecount isn't really a kref so don't make it one. · 29d08b3e
      Dave Airlie 提交于
      There were lots of places being inconsistent since handle count
      looked like a kref but it really wasn't.
      
      Fix this my just making handle count an atomic on the object,
      and have it increase the normal object kref.
      
      Now i915/radeon/nouveau drivers can drop the normal reference on
      userspace object creation, and have the handle hold it.
      
      This patch fixes a memory leak or corruption on unload, because
      the driver had no way of knowing if a handle had been actually
      added for this object, and the fbcon object needed to know this
      to clean itself up properly.

      drm/kms/fb: use slow work mechanism for normal hotplug also. · 4abe3520
      Dave Airlie 提交于
      a) slow work is always used now for any fbcon hotplug, as its not
         a fast task and is more suited to being ran under slow work.
      
      b) attempt to not do any fbdev changes when X is running as we'll
         just mess it up. This hooks set_par to hopefully do the changes
         once X hands control to fbdev.
      
      This also adds the nouveau/intel hotplug support.

      drm/fb: fix fbdev object model + cleanup properly. · 38651674
      Dave Airlie 提交于
      The fbdev layer in the kms code should act like a consumer of the kms services and avoid having relying on information being store in the kms core structures in order for it to work.
      
      This patch
      
      a) removes the info pointer/psuedo palette from the core drm_framebuffer structure and moves it to the fbdev helper layer, it also removes the core drm keeping a list of kernel kms fbdevs.
      b) migrated all the fb helper functions out of the crtc helper file into the fb helper file.
      c) pushed the fb probing/hotplug control into the driver
      d) makes the surface sizes into a structure for ease of passing
      This changes the intel/radeon/nouveau drivers to use the new helper.

      include cleanup: Update gfp.h and slab.h includes to prepare for breaking... · 5a0e3ad6
      Tejun Heo 提交于
      include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
      
      percpu.h is included by sched.h and module.h and thus ends up being
      included when building most .c files.  percpu.h includes slab.h which
      in turn includes gfp.h making everything defined by the two files
      universally available and complicating inclusion dependencies.
      
      percpu.h -> slab.h dependency is about to be removed.  Prepare for
      this change by updating users of gfp and slab facilities include those
      headers directly instead of assuming availability.  As this conversion
      needs to touch large number of source files, the following script is
      used as the basis of conversion.
      
        http://userweb.kernel.org/~tj/misc/slabh-sweep.py
      
      The script does the followings.
      
      * Scan files for gfp and slab usages and update includes such that
        only the necessary includes are there.  ie. if only gfp is used,
        gfp.h, if slab is used, slab.h.
      
      * When the script inserts a new include, it looks at the include
        blocks and try to put the new include such that its order conforms
        to its surrounding.  It's put in the include block which contains
        core kernel includes, in the same order that the rest are ordered -
        alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
        doesn't seem to be any matching order.
      
      * If the script can't find a place to put a new include (mostly
        because the file doesn't have fitting include block), it prints out
        an error message indicating which .h file needs to be added to the
        file.
      
      The conversion was done in the following steps.
      
      1. The initial automatic conversion of all .c files updated slightly
         over 4000 files, deleting around 700 includes and adding ~480 gfp.h
         and ~3000 slab.h inclusions.  The script emitted errors for ~400
         files.
      
      2. Each error was manually checked.  Some didn't need the inclusion,
         some needed manual addition while adding it to implementation .h or
         embedding .c file was more appropriate for others.  This step added
         inclusions to around 150 files.
      
      3. The script was run again and the output was compared to the edits
         from #2 to make sure no file was left behind.
      
      4. Several build tests were done and a couple of problems were fixed.
         e.g. lib/decompress_*.c used malloc/free() wrappers around slab
         APIs requiring slab.h to be added manually.
      
      5. The script was run on all .h files but without automatically
         editing them as sprinkling gfp.h and slab.h inclusions around .h
         files could easily lead to inclusion dependency hell.  Most gfp.h
         inclusion directives were ignored as stuff from gfp.h was usually
         wildly available and often used in preprocessor macros.  Each
         slab.h inclusion directive was examined and added manually as
         necessary.
      
      6. percpu.h was updated not to include slab.h.
      
      7. Build test were done on the following configurations and failures
         were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
         distributed build env didn't work with gcov compiles) and a few
         more options had to be turned off depending on archs to make things
         build (like ipr on powerpc/64 which failed due to missing writeq).
      
         * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
         * powerpc and powerpc64 SMP allmodconfig
         * sparc and sparc64 SMP allmodconfig
         * ia64 SMP allmodconfig
         * s390 SMP allmodconfig
         * alpha SMP allmodconfig
         * um on x86_64 SMP allmodconfig
      
      8. percpu.h modifications were reverted so that it could be applied as
         a separate patch and serve as bisection point.
      
      Given the fact that I had only a couple of failures from tests on step
      6, I'm fairly confident about the coverage of this conversion patch.
      If there is a breakage, it's likely to be something in one of the arch
      headers which should be easily discoverable easily on most builds of
      the specific arch.

      vga_switcheroo: initial implementation (v15) · 6a9ee8af
      Dave Airlie 提交于
      Many new laptops now come with 2 gpus, one to be used for low power
      modes and one for gaming/on-ac applications. These GPUs are typically
      wired to the laptop panel and VGA ports via a multiplexer unit which
      is controlled via ACPI methods.
      
      4 combinations of systems typically exist - with 2 ACPI methods.
      Intel/ATI - Lenovo W500/T500 - use ATPX ACPI method
      ATI/ATI - some ASUS - use ATPX ACPI Method
      Intel/Nvidia - - use _DSM ACPI method
      Nvidia/Nvidia -  - use _DSM ACPI method.
      
      TODO:
      This patch adds support for the ATPX method and initial bits
      for the _DSM methods that need to written by someone with
      access to the hardware.
      Add a proper non-debugfs interface - need to get some proper
      testing first.
      
      v2: add power up/down support for both devices
      on W500 puts i915/radeon into D3 and cuts power to radeon.
      
      v3: redo probing methods, no DMI list, drm devices call to
      register with switcheroo, it tries to find an ATPX method on
      any device and once there is two devices + ATPX it inits the
      switcher.
      
      v4: ATPX msg handling using buffers - should work on more machines
      
      v5: rearchitect after more mjg59 discussion - move ATPX handling to
          radeon driver.
      
      v6: add file headers + initial nouveau bits (to be filled out).
      
      v7: merge delayed switcher code.
      
      v8: avoid suspend/resume of gpu that is off
      
      v9: rearchitect - mjg59 is always right. - move all ATPX code to
      radeon, should allow simpler DSM also proper ATRM handling
      
      v10: add ATRM support for radeon BIOS, add mutex to lock vgasr_priv
      
      v11: fix bug in resuming Intel for 2nd time.
      
      v12: start fixing up nvidia code blindly.
      
      v13: blindly guess at finishing nvidia code
      
      v14: remove radeon audio hacks - fix up intel resume more like upstream
      
      v15: clean up printks + remove unnecessary igd/dis pointers
      
      mount debugfs
      
      /sys/kernel/debug/vgaswitcheroo/switch - should exist if ATPX detected
       + 2 cards.
      
      DIS - immediate change to discrete
      IGD - immediate change to IGD
      DDIS - delayed change to discrete
      DIGD - delayed change to IGD
      ON - turn on not in use
      OFF - turn off not in use
      
      Tested on W500 (Intel/ATI) and T500 (Intel/ATI)

      drm/nouveau: Add DRM driver for NVIDIA GPUs · 6ee73861
      Ben Skeggs 提交于
      This adds a drm/kms staging non-API stable driver for GPUs from NVIDIA.
      
      This driver is a KMS-based driver and requires a compatible nouveau
      userspace libdrm and nouveau X.org driver.
      
      This driver requires firmware files not available in this kernel tree,
      interested parties can find them via the nouveau project git archive.
      
      This driver is reverse engineered, and is in no way supported by nVidia.
      
      Support for nearly the complete range of nvidia hw from nv04->g80 (nv50)
      is available, and the kms driver should support driving nearly all
      output types (displayport is under development still) along with supporting
      suspend/resume.
      
      This work is all from the upstream nouveau project found at
      nouveau.freedesktop.org.
