* radeonfb: Whack the PCI PM register until it sticksBenjamin Herrenschmidt2009-03-22
| | | | | | | | | | | | | | | | | | This fixes a regression introduced when we switched to using the core pci_set_power_state(). The chip seems to need the state to be written over and over again until it sticks, so we do that. Note that the code is a bit blunt, without timeout, etc... but that's pretty much because I put back in there the code exactly as it used to be before the regression. I still add a call to pci_set_power_state() at the end so that ACPI gets called appropriately on x86.

| * radeonfb/aty128fb: Disable broken early resume hook for PowerBooksBenjamin Herrenschmidt2009-03-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | radeonfb and aty128fb have a special hook called by the PowerMac platform code very very early on resume from sleep to bring the screen back. This is useful for debugging wakup problems, but unfortunately, this also became a source of problems of its own. The hook is called extremely early, with interrupts still off, and the code path involved with that code nowadays rely on things like taking mutexes, GFP_KERNEL allocations, etc... In addition, the driver now relies on the PCI core to restore the standard config space before calling resume which doesn't happen with this early code path. I'm keeping the code in but commented out along with a fixup call to pci_restore_state(). The reason is that I still want to make it easy to re-enable temporarily to track wake up problems, and it's possible that I can revive it at some stage if we make sleeping things save to call in early resume using a system state. In the meantime, this should fix several reported regressions. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
* | i810: fix kernel crash fix when struct fb_var_screeninfo is suppliedSamuel CUELLA2009-03-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prevent the kernel from being crashed by a divide-by-zero operation when supplied an incorrectly filled 'struct fb_var_screeninfo' from userland. Previously i810_main.c:1005 (i810_check_params) was using the global 'yres' symbol previously defined at i810_main.c:145 as a module parameter value holder (i810_main.c:2174). If i810fb is compiled-in or if this param doesn't get a default value, this direct usage leads to a divide-by-zero at i810_main.c:1005 (i810_check_params). The patch simply replace the 'yres' global, perhaps undefined symbol usage by a given parameter structure lookup. This problem occurs with directfb, mplayer -vo fbdev, SDL library.

* fbdev/drm: fix Kconfig submenu mess in "Graphics support"Krzysztof Helt2009-02-18
| | | | | | | | | | | | | | | | | | | | | | | Submenus of the graphics support "Support for frame buffer devices" and "Direct Rendering Manager (XFree86 4.1.0 and higher DRI support)" are broken in half after latest changes for Intel 915 mode setting support. The DRM subsection is broken because one option is put outside the choice section it depends on. The frame buffers part is broken then due to circular dependency. Fix this by make Intel frame buffers depend on CONFIG_INTEL_AGP. Kconfigs are broken by d2f59357700487a8b944f4f7777d1e97cf5ea2ed ("drm/i915: select framebuffer support automatically").

The i915 driver recently added a 'depends on FB' rule to its Kconfig entry - which silently turns off DRM_I915 if someone has a working config but no CONFIG_FB selected, and upgrades to the latest upstream kernel. Norbert Preining reported this problem: Bug-Entry : http://bugzilla.kernel.org/show_bug.cgi?id=12599 Subject : dri /dev node disappeared with 2.6.29-rc1 So change it to "select FB", which auto-selects framebuffer support. This way the driver keeps working, regardless of whether FB was enabled before or not. Kconfig select's of interactive options can be problematic to dependencies and can cause build breakages - but in this case it's safe because it's a leaf entry with no dependencies of its own. ( There is some minor circular dependency fallout as FB_I810 and FB_INTEL also used 'depends on FB' constructs - update those to "select FB" too. ) Reported-by: Norbert Preining <preining@logic.at> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Dave Airlie <airlied@linux.ie>
* | radeonfb: Fix resume from D3Cold on some platformsBenjamin Herrenschmidt2009-02-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For historical reason, this driver used its own saving/restoring of the PCI config space, and used the state of it on resume as an indication as to whether it needed to re-POST the chip or not. This methods breaks with the later core changes since the core will have restored things for us. This patch fixes it by removing that custom code, using standard core methods to save/restore state, and testing for the need to re-POST by comparing the content of a few key PLL registers.

This seems to depend on a value (4) read from PLL_EXT_CNTL register, which leads to incorrect DSP config parameters to be written to the chip. This patch uses a value calculated by aty_init_pll_ct instead, as a starting point. There are questions as to whether this should be extended to other platforms or maybe made dependent on specific chip types, but in the meantime, this has been tested on various powermacs and works for them so let's commit it.

* | fbdev: c2p/atafb - Add support for Atari interleaved bitplanesGeert Uytterhoeven2009-01-12
| | | | | | | | | | | | | | The c2p() for normal bitplanes is not suitable for interleaved bitplanes with 2 bytes of interleave, causing a garbled penguin logo. Add c2p_iplan2(). Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>

* | fbdev: c2p - CleanupsGeert Uytterhoeven2009-01-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - Improve comments and naming - Convert macros to static inline functions - Remove superfluous `break' after `return' - Make sure we get a build-time error (undefined reference to 'c2p_unsupported') in case of future misuse - Replace `unsigned long' by `u32' in comp(), as that's what all callers use - Use {get,put}_unaligned_be32() in store_planar{,_masked}() - Use void * for arbitrary pointers - Use a union to represent pixels/words, to avoid casts Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>

* | fbdev: atafb - Fix 16 bpp consoleGeert Uytterhoeven2009-01-12
| | | | | | | | | | | | | | | | | | - 16 bpp must use the cfb_*() ops - 16 bpp needs to set up info->pseudo_palette[] (was fbcon_cfb16_cmap[] in 2.4.x) - Kill commented out 2.4.x fbcon remnants Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
* | fbdev: atafb - Fix line length handlingGeert Uytterhoeven2009-01-12
|/ | | | | | | | | - Make sure par->next_line is always set (this was done for Falcon only), as all the text console drawing operations need a valid par->next_line, - Make sure fix->line_length is always set, as some userspace applications need it because they don't have fallback code for the case where it's zero.
