* tg3: Fix 5761 NVRAM sizesMatt Carlson2008-05-022-13/+29
| | | | | | | | | | The 5761 NVRAM sizes assigned to the nvram_size member are half as big as they should be. This patch corrects the NVRAM sizes and replaces the hardcoded constants with preprocessor constants for readability.

* tg3: Use constant 500KHz MI clock on adapters with a CPMUMatt Carlson2008-05-022-6/+14
| | | | | | | | | | | | | | | | | | | | The MI clock is not configured correctly on adapters with the CPMU present. The tg3 driver has code which statically sets the MI clock to be a fraction of the speed at which the core clock is running. However, the CPMU can change the adapter's core clock frequency based on operating conditions. Consequently, the MI will run slow when the core's clock has been slowed down. There is a new 500KHz constant frequency clock available on adapters with a CPMU. This patch removes the static core clock scaling and configures the MI clock to use this new 500KHz clock instead. Running the MI clock at slower speeds will not directly result in data corruption, but it does challenge the PHY read and write routine timeouts.

| | | | | | | | | | | | | WARN_ON_ONCE() gives a stack trace including the full module list. Having this in the kernel dump for the timeout case in the generic netdev watchdog will help us see quicker which driver is involved. It also allows us to collect statistics and patterns in terms of which drivers have this event occuring.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have a race between fcntl() and close() that can lead to dnotify_struct inserted into inode's list *after* the last descriptor had been gone from current->files. Since that's the only point where dnotify_struct gets evicted, we are screwed - it will stick around indefinitely. Even after struct file in question is gone and freed. Worse, we can trigger send_sigio() on it at any later point, which allows to send an arbitrary signal to arbitrary process if we manage to apply enough memory pressure to get the page that used to host that struct file and fill it with the right pattern...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So Ingo finally did figure out why UML broke with this option: UML passes gcc the -fno-unit-at-a-time flag, and apparently that wreaks havoc with gcc's inlining. We could turn off -fno-unit-at-a-time for UML for gcc4+ (which is what x86 does), but there's bad blood about this whole option, and it does show that the thing is just fragile as heck. So let tempers cool, and disable the thing, and we can revisit the decision later.

The ioremap that OLPC uses is: romsig = ioremap(0xffffffc0, 16); The commit that breaks it is basically: - for (pfn = phys_addr >> PAGE_SHIFT; pfn < max_pfn_mapped && - (pfn << PAGE_SHIFT) < last_addr; pfn++) { + for (pfn = phys_addr >> PAGE_SHIFT; + (pfn << PAGE_SHIFT) < last_addr; pfn++) { + Previously, the 'pfn < max_pfn_mapped' check would've caused us to not enter the loop. Removing that check means we loop infinitely. The reason for that is because pfn is 0xfffff, and last_addr is 0xffffffcf. The remaining check that is used to exit the loop is not sufficient; when pfn<<PAGE_SHIFT is 0xfffff000, that is less than 0xffffffcf; when we increment pfn and it overflows (pfn == 0x100000), pfn<<PAGE_SHIFT ends up being 0. That, of course, is less than last_addr. In effect, pfn<<PAGE_SHIFT is never lower than last_addr. The simple fix for this is to limit the last_addr check to the PAGE_MASK; a patch is below.

J.A. Magallón reports the same. native_cpu_up: bad cpu 2 native_cpu_up: bad cpu 3 The mach-default cpu_present_to_apicid() was just returning cpu number (2, 3) instead of apicid (6, 7): looks like we now need the x86_64 code even for the i386 case. Comparing with other versions of cpu_present_to_apicid(), it seems a good idea to include an NR_CPUS test too, since cpu_present() doesn't include that; but that wasn't a problem here, and may no problem at all. Prior to that smpboot merge, my Xeon booted the two HT siblings on one physical first, then the two siblings on the other physical after - when i386, but alternated them when x86_64. Since the merge, the x86_64 sequence is unchanged, but the i386 sequence is now like x86_64. I prefer this consistency, and I prefer the new sequence: booting with maxcpus=2 then uses the independent physicals without HT sharing.

Once all the X drivers move to ioremap_wc(), we can go back to strong UC semantics for ioremap() and ioremap_nocache(). To avoid attribute aliasing issues, pci_mmap_page_range() will also use UC_MINUS for default non write-combining mapping request. Next steps: a) change all the video drivers using ioremap() or ioremap_nocache() and adding WC MTTR using mttr_add() to ioremap_wc() b) for strict usage, we can go back to strong uc semantics for ioremap() and ioremap_nocache() after some grace period for completing step-a. c) user level X server needs to use the appropriate method for setting up WC mapping (like using resourceX_wc sysfs file instead of adding MTRR for WC and using /dev/mem or resourceX under /sys) Signed-off-by: Suresh Siddha <suresh.b.siddha@intel.com> Signed-off-by: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
