| * [PATCH] ppc64: Fix booting on latest G5 modelsBenjamin Herrenschmidt2005-05-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The latest speedbumped Apple G5 models have a "bug" in the Open Firmware device tree that lacks the proper interrupt routing information for the northbridge i2c controller. Apple's driver silently falls back into a sub-optimal "polled" mode (heh, maybe they didn't even notice the bug because of that :), our driver didn't properly check and crashes :( This patch fixes our driver to not crash, and adds code to the prom_init() OF trampoline code that detects the "bug" and adds the missing information back for this chipset revision. This fixes booting and thermal control on these models. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
| * [PATCH] fix for __generic_file_aio_read() to return 0 on EOFSuparna Bhattacharya2005-05-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I came across the following problem while running ltp-aiodio testcases from ltp-full-20050405 on linux-2.6.12-rc3-mm3. I tried running the tests with EXT3 as well as JFS filesystems. One or two fsx-linux testcases were hung after some time. These testcases were hanging at wait_for_all_aios(). Debugging shows that there were some iocbs which were not getting completed eventhough the last retry for those returned -EIOCBQUEUED. Also all such pending iocbs represented READ operation. Further debugging revealed that all such iocbs hit EOF in the DIO layer. To be more precise, the "pos" from which they were trying to read was greater than the "size" of the file. So the generic_file_direct_IO returned 0. This happens rarely as there is already a check in __generic_file_aio_read(), for whether "pos" < "size" before calling direct IO routine. >size = i_size_read(inode); >if (pos < size) { > retval = generic_file_direct_IO(READ, iocb, > iov, pos, nr_segs); But for READ, we are taking the inode->i_sem only in the DIO layer. So it is possible that some other process can change the size of the file before we take the i_sem. In such a case ( when "pos" > "size"), the __generic_file_aio_read() would return -EIOCBQUEUED even though there were no I/O requests submitted by the DIO layer. This would cause the AIO layer to expect aio_complete() for THE iocb, which doesnot happen. And thus the test hangs forever, waiting for an I/O completion, where there are no requests submitted at all. The following patch makes __generic_file_aio_read() return 0 (instead of returning -EIOCBQUEUED), on getting 0 from generic_file_direct_IO(), so that the AIO layer does the aio_complete(). Testing: I have tested the patch on a SMP machine(with 2 Pentium 4 (HT)) running linux-2.6.12-rc3-mm3. I ran the ltp-aiodio testcases and none of the fsx-linux tests hung. Also the aio-stress tests ran without any problem.

This fixes it by using "preempt_enable_no_resched()" instead of the "preempt_enable()", and thus avoids the useless preempt_check_resched() just before re-enabling bottom halves.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new period/dt setting routines don't get the coupling of these parameters correct.

Currently it's rather fancifully refcounted in the queuecommand callback. This patch moves allocation and destroy to their correct places in slave_alloc/slave_destory. Now we can guarantee that everywhere a device is requested, it's actually been allocated, so don't check for this anymore. Additionally, the per device busy timer was the only source of potential use after free. It's been deleted because Linux does the correct thing with busy returns, so there's no need to implement a separate timer in the driver. Finally, implement code that forces all the device parameters to zero (i.e. async and narrow) in the slave alloc, inform the spi class of the bios recorded maximums and wait until slave configure before trying anything more adventurous.

The root cause is the sub 32bit process fails to restart the syscall after it is interrupted by a signal. The syscall number of sys_restart_syscall in table sys_call_table is __NR_restart_syscall (219) while it's __NR_ia32_restart_syscall (0) in ia32_sys_call_table. When regs->rax==(unsigned long)-ERESTART_RESTARTBLOCK, function do_signal doesn't distinguish if the process is 64bit or 32bit, and always sets restart syscall number as __NR_restart_syscall (219).

Since the hotplug code is holding a spinlock at this point, we cannot take the cpuset semaphore, cpuset_sem, as would seem to be required either to update the tasks cpuset, or to scan up the nested cpuset chain, looking for the nearest cpuset ancestor that still has some CPUs that are online. So we just punt and blast the tasks cpus_allowed with all bits allowed. This reverts these lines of code to what they were before the cpuset patch. And it updates the cpuset Doc file, to match. The one known alternative to this that seems to work came from Dinakar Guniguntala, and required the hotplug code to take the cpuset_sem semaphore much earlier in its processing. So far as we know, the increased locking entanglement between cpusets and hot plug of this alternative approach is not worth doing in this case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If you tried to open a packet device first in read-only mode and then a second time in read-write mode, the second open succeeded even though the device was not correctly set up for writing. If you then tried to write data to the device, the writes would fail with I/O errors. This patch prevents that problem by making the second open fail with -EBUSY.

| * | [SPARC64]: Fix bad performance side effect of strbuf timeout changes.David S. Miller2005-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The recent change to add a timeout to strbuf flushing had a negative performance impact. The udelay()'s are too long, and they were done in the wrong order wrt. the register read checks. Fix both, and things are happy again. There are more possible improvements in this area. In fact, PCI streaming buffer flushing seems to be part of the bottleneck in network receive performance on my SunBlade1000 box. Signed-off-by: David S. Miller <davem@davemloft.net>
