      drm/radeon/kms/pm: rework power management · ce8f5370
      Alex Deucher authored
      - Separate dynpm and profile based power management methods.  You can select the pm method
        by echoing the selected method ("dynpm" or "profile") to power_method in sysfs.
      - Expose basic 4 profile in profile method
        "default" - default clocks
        "auto" - select between low and high based on ac/dc state
        "low" - DC, low power mode
        "high" - AC, performance mode
        The current base profile is "default", but it should switched to "auto" once we've tested
        on more systems.  Switching the state is a matter of echoing the requested profile to
        power_profile in sysfs.  The lowest power states are selected automatically when dpms turns
        the monitors off in all states but default.
      - Remove dynamic fence-based reclocking for the moment.  We can revisit this later once we
        have basic pm in.
      - Move pm init/fini to modesetting path.  pm is tightly coupled with display state.  Make sure
        display side is initialized before pm.
      - Add pm suspend/resume functions to make sure pm state is properly reinitialized on resume.
      - Remove dynpm module option.  It's now selectable via sysfs.

      drm/radeon/kms/pm: add additional asic callbacks · 49e02b73
      Alex Deucher authored
      - pm_misc() - handles voltage, pcie lanes, and other non
      clock related power mode settings.  Currently disabled.
      Needs further debugging
      - pm_prepare() - disables crtc mem requests right now.
      All memory clients need to be disabled when changing
      memory clocks.  This function can be expanded to include
      disabling fb access as well.
      - pm_finish() - enable active memory clients.

      drm/radeon/kms: add support for gui idle interrupts (v4) · 2031f77c
      Alex Deucher authored
      Useful for certain power management operations.  You
      need to wait for the GUI engine (2D, 3D, CP, etc.) to be
      idle before changing clocks or adjusting engine parameters.
      (v2) Fix gui idle enable on pre-r6xx asics
      (v3) The gui idle interrrupt status bit is permanently asserted
      on pre-r6xx chips, but the interrrupt is still generated.
      workaround it in the driver.
      (v4) Add support for evergreen

      drm/radeon/kms: fence cleanup + more reliable GPU lockup detection V4 · 225758d8
      Jerome Glisse authored
      This patch cleanup the fence code, it drops the timeout field of
      fence as the time to complete each IB is unpredictable and shouldn't
      be bound.
      The fence cleanup lead to GPU lockup detection improvement, this
      patch introduce a callback, allowing to do asic specific test for
      lockup detection. In this patch the CP is use as a first indicator
      of GPU lockup. If CP doesn't make progress during 1second we assume
      we are facing a GPU lockup.
      To avoid overhead of testing GPU lockup frequently due to fence
      taking time to be signaled we query the lockup callback every
      500msec. There is plenty code comment explaining the design & choise
      inside the code.
      This have been tested mostly on R3XX/R5XX hw, in normal running
      destkop (compiz firefox, quake3 running) the lockup callback wasn't
      call once (1 hour session). Also tested with forcing GPU lockup and
      lockup was reported after the 1s CP activity timeout.
      V2 switch to 500ms timeout so GPU lockup get call at least 2 times
         in less than 2sec.
      V3 store last jiffies in fence struct so on ERESTART, EBUSY we keep
         track of how long we already wait for a given fence
      V4 make sure we got up to date cp read pointer so we don't have
         false positive

      include cleanup: Update gfp.h and slab.h includes to prepare for breaking... · 5a0e3ad6
      Tejun Heo authored
      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.
      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
      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
      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
      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.

      drm/radeon/kms: simplify memory controller setup V2 · d594e46a
      Jerome Glisse authored
      Get rid of _location and use _start/_end also simplify the
      computation of vram_start|end & gtt_start|end. For R1XX-R2XX
      we place VRAM at the same address of PCI aperture, those GPU
      shouldn't have much memory and seems to behave better when
      setup that way. For R3XX and newer we place VRAM at 0. For
      R6XX-R7XX AGP we place VRAM before or after AGP aperture this
      might limit to limit the VRAM size but it's very unlikely.
      For IGP we don't change the VRAM placement.
      Tested on (compiz,quake3,suspend/resume):
      RPB: resume previously broken
      V2 correct commit message to reflect more accurately the bug
      and move VRAM placement to 0 for most of the GPU to avoid
      limiting VRAM.
