I\u0027m not entirely certain of why, I susepct they often contained\ngarbage on x86 but it\u0027s hard to tell. This causes the current generic\ncode to always call pci_assign_resource() when trying to access the said\nROM from sysfs, which will try to re-assign some new address regardless\nof what the ROM BAR was already set to at boot time. This can be a\nproblem on hypervisor platforms like pSeries where we aren\u0027t supposed\nto move PCI devices around (and in fact probably can\u0027t).\n\nSecond, our code that generates the PCI tree from the OF device-tree\n(instead of doing config space probing) which we mostly use on pseries\nat the moment, didn\u0027t set the (new) flag IORESOURCE_SIZEALIGN on any\nresource. That means that any attempt at re-assigning such a resource\nwith pci_assign_resource() would fail due to resource_alignment()\nreturning 0.\n\nThis fixes this by doing these two things:\n\n - The code that calculates resource flags based on the OF device-node\nis improved to set IORESOURCE_SIZEALIGN on any valid BAR, and while at\nit also set IORESOURCE_READONLY for ROMs since we were lacking that too\n\n - We now allocate ROM resources as part of the resource tree. However\nto limit the chances of nasty conflicts due to busted firmwares, we\nonly do it on the second pass of our two-passes allocation scheme,\nso that all valid and enabled BARs get precedence.\n\nThis brings pSeries back the ability to access PCI ROMs via sysfs (and\nthus initialize various video cards from X etc...).\n\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "b173f03d7c48d3346541f26e0b29690dbadca279", "tree": "9eec335a778a6bb715feb4fd0b000fa091d02b0f", "parents": [ "951c4df5b7703137bf4eee002d98d083fbc890cc" ], "author": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Thu May 14 18:34:06 2009 +0000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Fri May 15 16:43:42 2009 +1000" }, "message": "powerpc/pseries: Really fix the oprofile CPU type on pseries\n\nMy previous pach for fixing the oprofile CPU type got somewhat mismerged\n(by my fault) when it collided with another related patch.
