      [PATCH] 3/5 powerpc: Add platform functions interpreter · 5b9ca526
      Benjamin Herrenschmidt 提交于
      This is the platform function interpreter itself along with the backends
      for UniN/U3/U4, mac-io, GPIOs and i2c. It adds the ability to execute
      those do-platform-* scripts in the device-tree (at least for most
      devices for which a backend is provided). This should replace the clock
      spreading hacks properly. It might also have an impact on all sort of
      machines since some of the scripts marked "at init" will now be executed
      on boot (or some other on sleep/wakeup), those will possibly do things
      that the kernel didn't do at all, like setting some values into some i2c
      devices (changing thermal sensor calibration or conversion rate) etc...
      Thus regression testing is MUCH welcome. Also loook for errors in dmesg.
      That's also why I've left rather verbose debugging enabled in this
      version of the patch.
      
      (I do expect some Windtunnel G4s to show some errors as they have an i2c
      clock chip on the PMU bus that uses some primitives that the i2c backend
      doesn't implement yet. I really need users that have one of those
      machine to come back to me so we can get that done right, though the
      errors themselves should be harmless, I suspect the machine might not
      run at full speed).

      [PATCH] 1/5 powerpc: Rework PowerMac i2c part 1 · 730745a5
      Benjamin Herrenschmidt 提交于
      This is the first part of a rework of the PowerMac i2c code. It
      completely reworks the "low_i2c" layer. It is now more flexible,
      supports KeyWest, SMU and PMU i2c busses, and provides functions to
      match device nodes to i2c busses and adapters.
      
      This patch also extends & fix some bugs in the SMU driver related to i2c
      support and removes the clock spreading hacks from the pmac feature code
      rather than adapting them to the new API since they'll be replaced by
      the platform function code completely in patch 3/5

      [PATCH] powerpc: Experimental support for new G5 Macs (#2) · 1beb6a7d
      Benjamin Herrenschmidt 提交于
      This adds some very basic support for the new machines, including the
      Quad G5 (tested), and other new dual core based machines and iMac G5
      iSight (untested). This is still experimental !  There is no thermal
      control yet, there is no proper handing of MSIs, etc.. but it
      boots, I have all 4 cores up on my machine. Compared to the previous
      version of this patch, this one adds DART IOMMU support for the U4
      chipset and thus should work fine on setups with more than 2Gb of RAM.

      [PATCH] ppc32: Fix AGP and sleep again · 0c541b44
      Benjamin Herrenschmidt 提交于
      My previous patch that added sleep support for uninorth-agp and some AGP
      "off" stuff in radeonfb and aty128fb is breaking some configs.  More
      specifically, it has problems with rage128 setups since the DRI code for
      these in X doesn't properly re-enable AGP on wakeup or console switch
      (unlike the radeon DRM).
      
      This patch fixes the problem for pmac once for all by using a different
      approach.  The AGP driver "registers" special suspend/resume callbacks with
      some arch code that the fbdev's can later on call to suspend and resume
      AGP, making sure it's resumed back in the same state it was when suspended.
       This is platform specific for now.  It would be too complicated to try to
      do a generic implementation of this at this point due to all sort of weird
      things going on with AGP on other architectures.  We'll re-work that whole
      problem cleanly once we finally merge fbdev's and DRI.
      
      In the meantime, please apply this patch which brings back some r128 based
      laptops into working condition as far as system sleep is concerned.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
