Basically, now: 1. max_bus_speed is used to set the device to gen2 speeds 2. on power there's no longer a conflict between the pseries call and other architectures, because the overwrite is done via a ppc_md hook 3. radeon is using bus->max_bus_speed instead of drm_pcie_get_speed_cap_mask for gen2 capability detection The first patch consists of some architecture changes, such as adding a hook on powerpc for pci_root_bridge_prepare, so that pseries will initialize it to a function, while all other architectures get a NULL pointer. So that whenever whenever pci_create_root_bus is called, we'll get max_bus_speed properly setup from OpenFirmware. The second patch consists of simple radeon changes not to call drm_get_pcie_speed_cap_mask anymore. I assume that on x86 machines, the max_bus_speed property will be properly set already. </blockquote><div> The radeon changes are : Reviewed-by: Jerome Glisse <<a href="mailto:jglisse@redhat.com">jglisse@redhat.com</a>> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Lucas Kannebley Tavares (2): ppc64: perform proper max_bus_speed detection radeon: use max_bus_speed to activate gen2 speeds arch/powerpc/include/asm/machdep.h | 2 + arch/powerpc/kernel/pci-common.c | 8 +++++ arch/powerpc/platforms/pseries/pci.c | 51 ++++++++++++++++++++++++++++++++ arch/powerpc/platforms/pseries/setup.c | 4 ++ drivers/gpu/drm/radeon/evergreen.c | 9 +---- drivers/gpu/drm/radeon/r600.c | 8 +---- drivers/gpu/drm/radeon/rv770.c | 8 +---- 7 files changed, 69 insertions(+), 21 deletions(-) -- 1.7.4.4 _______________________________________________ dri-devel mailing list <a href="mailto:dri-devel@lists.freedesktop.org">dri-devel@lists.freedesktop.org</a> <a href="http://lists.freedesktop.org/mailman/listinfo/dri-devel" target="_blank">http://lists.freedesktop.org/mailman/listinfo/dri-devel</a> </blockquote></div>
