X has been failing to start on my quad G5 powermac since commit 1fd0f525 ("powerpc: Fix domain numbers in /proc on 64-bit") went in. The reason is that the change allows X to see the PCI-PCI bridge above the video card (previously it was obscured by the fact that there were two "00" directories in /proc/bus/pci), and the pciconfig_iobase system call on the bridge is failing because of a hack that we have to return information about the AGP bus when X asks about bus 0. This machine doesn't have an AGP bus (it has PCI Express) and so the pciconfig_iobase call is returning -1, which ultimately causes X to fail to start. This fixes it by checking that we have an AGP bridge before redirecting the pciconfig_iobase call to return information about the AGP bus. With this, X starts successfully both on a quad G5 with PCI Express and on an older dual G5 with AGP. Signed-off-by:

The current code for providing processor cache information in sysfs has the following deficiencies: - several complex functions that are hard to understand - implicit recursion (cache_desc_release -> kobject_put -> cache_desc_release) - explicit recursion (create_cache_index_info) - use of two per-cpu arrays when one would suffice - duplication of work on systems where CPUs share cache Also, when I looked at implementing support for a shared_cpu_map attribute, it was pretty much impossible to handle hotplug without checking every single online CPU's cache_desc list and fixing things up... not that this is a hot path, but it would have introduced O(n^2)-ish behavior during boot. Addressing this involved rethinking the core data structures used, which didn't lend itself to an incremental approach. This implementation maintains a "forest" (potentially more than one tree) of cache objects which reflects the system's cache topology. Cache objects are instantiated as needed as CPUs come online. A per-cpu array is used mainly for sysfs-related bookkeeping; the objects in the array just point to the appropriate points in the forest. This maintains compatibility with the existing code and includes some enhancements: - Implement the shared_cpu_map attribute, which is essential for enabling userspace to discover the system's overall cache topology. - Use cache-block-size properties if cache-line-size is not available. I chose to place this implementation in a new file since it would have roughly doubled the size of sysfs.c, which is already kind of messy. Signed-off-by:

This patch makes the default install script (arch/powerpc/boot/install.sh) copy the bootable image files into the install directory. Before this patch only the vmlinux image file was copied. This patch makes the default 'make install' command useful for embedded development when $(INSTALL_PATH) is set in the environment. As a side effect, this patch changes the calling convention of the install.sh script. Instead of a single 5th parameter, the script is now passed a list of all the target images stored in the $(image-y) Makefile variable. This should be backwards compatible with existing install scripts since it just adds additional arguments and does not change existing ones. Signed-off-by:

Both users of careful_allocation() immediately memset() the result. So, just do it in one place. Also give careful_allocation() a 'z' prefix to bring it in line with kzmalloc() and friends. Signed-off-by:

Dave Hansen authored
Since we memset() the result in both of the uses here, just make careful_alloc() return a virtual address. Also, add a separate variable to store the physial address that comes back from the lmb_alloc() functions. This makes it less likely that someone will screw it up forgetting to convert before returning since the vaddr is always in a void* and the paddr is always in an unsigned long. I admit this is arbitrary since one of its users needs a paddr and one a vaddr, but it does remove a good number of casts. Signed-off-by:

If we fail a bootmem allocation, the bootmem code itself panics. No need to redo it here. Also change the wording of the other panic. We don't strictly have to allocate memory on the specified node. It is just a hint and that node may not even *have* any memory on it. In that case we can and do fall back to other nodes. Signed-off-by:

There's a problem on some embedded platforms when we re-assign everything on PCI, such as 44x. The generic code tries to avoid assigning devices to addresses overlapping the low legacy addresses such as VGA hard decoded areas using constants that are unfortunately no good for us, as they don't take into account the address translation we do to access PCI busses. Thus we end up allocating things like IO BARs to 0, which is technically legal, but will shadow hard decoded ports for use by things like VGA cards. This works around it by attempting to reserve legacy regions before we try to assign addresses. NOTE: This may have nasty side effects in cases I haven't tested yet: - We try to use FW mappings (ie. powermac) and the FW has allocated a conflicting address over those legacy regions. This will typically happen. I would expect the new code to just fail with an informative message without harm but I haven't had a chance to test that scenario yet. - A device with fixed BARs overlapping those legacy addresses such as an IDE controller in legacy mode is in the system. I don't know for sure yet what will happen there, I have to test :-) Ideally, we should change PCIBIOS_MIN_IO/MIN_MEM accross the board to take a bus pointer so they can provide appropriate per-bus translated values to the generic code but that's a more invasive patch. I will do that in the future, but in the meantime, this fixes the problem locally Signed-off-by: -

This patch updates the MAINTAINERS entries for the media drivers. We are doing a few changes during 2009 to improve patch handling for drivers/media stuff. Currently, v4l-dvb-maintainer list at linuxtv.org were used to to be v4l/dvb driver maintainers ML, in order to keep track of patch merge requests and to receive bug fixes. This list allows posting for everybody, but, in order to avoid spam, the user subscribe/unsubscribe at the ML is moderated. Other development discussions and end-user forums happened on two separated ML (one for V4L and another for DVB). At the beginning of 2009, we've created linux-media@vger.kernel.org, meaning to be the main upstream development mailing list for drivers/media, including V4L and DVB core and drivers. The choice for vger.kernel.org were due to the fact that most of upstream lists are there. Also, its anti-spam filtering rules are better than what we currently have at linuxtv.org. For now, both video4linux-list and linux-dvb ML will remain active, but more focused on end users. It is expected that those lists will gradually be replaced also by linux-media@vger.kernel.org. This patch reflect those changes at linux MAINTAINERS file. Since the development and bug fix discussions will now happen at linux-media@vger.kernel.org, this patch does the following changes - replaces v4l-dvb-maintainer ML for the new linux-media@vger.kernel.org; - replaces video4linux ML for the new linux-media@vger.kernel.org; While here, it also: - Fixes the existing -git tree entries for drivers/media (since the repository name changed); - Adds the missing drivers/media -git tree entry on a few maintainers entries that don't point to a tree.

As Randy Dunlap <randy.dunlap@oracle.com> reported, cx88 has some compilation issues: drivers/built-in.o: In function `cx88_call_i2c_clients': (.text+0x20af17): undefined reference to `videobuf_dvb_get_frontend' drivers/built-in.o: In function `cx8802_probe': cx88-mpeg.c:(.devinit.text+0x268c4): undefined reference to `videobuf_dvb_alloc_frontend' cx88-mpeg.c:(.devinit.text+0x268ea): undefined reference to `videobuf_dvb_dealloc_frontends' With those configs: CONFIG_VIDEO_CX88=y CONFIG_VIDEO_CX88_BLACKBIRD=y CONFIG_VIDEO_CX88_DVB=m CONFIG_DVB_CORE=m After carefully examining the code, with the current code, several cx88 drivers (cx8800, cx8802, cx88_dvb and cx88_blackbird) should be compiled as a module, if one of them is marked as such. Just fixing Kconfig could create a very complex set of rules. Also, this hides a problem with the current approach where the dvb functionality weren't confined inside dvb module. What happens is that: - cx88-i2c (part of cx8800) has some special rules if DVB; - cx88-mpeg (cx8802 module) has also part of DVB init code; - cx88-dvb has the rest of the dvb code; - cx88-blackbird can be used with cx88-mpeg, having cx88-dvb or not. So, instead of doing some tricks at Kconfig and wait for a next breakage, this patch moves the dvb code inside cx88-i2c and cx88-mpeg into cx88-dvb. Another problem is that cx8802 were being compiled, even without cx88-dvb and cx88-blackbird modules. While on this code, let's fix also a reported problem: http://www.linuxtv.org/pipermail/linux-dvb/2009-January/031225.html A solution for the issue were proposed here: http://www.mail-archive.com/linux-media@vger.kernel.org/msg00021.html Thanks to Randy, Andy, Gregoire and Thomas for helping us to detect and solve the issues.
