Revert the offending part. It broke because: a) because this part doesn't fall under the description b) the author didn't know what he was doing here c) the author didn't try to compile the existing code and see that it worked perfectly. d) the author didn't ask us what was happening e) you didn't either, and somebody there should have learned that UML is a bit different. In fact, UML is special in linking to host libc and using its includes. In particular, since host includes always define both __BIG_ENDIAN and __LITTLE_ENDIAN, ntohll() macros started thinking to be in a big-endian world; and on-disk compatibility was broken. Many thanks go to Nix for reporting the problem and correctly diagnosing an endianness problem. Btw, this patch restores the previous code, which worked; but the definitions would be uncorrect if used in kernelspace files. Next patch addresses that.

Wysocki" Date: Sun, 9 Oct 2005 21:19:40 +0200 Subject: [PATCH] x86_64: Set up safe page tables during resume The following patch makes swsusp avoid the possible temporary corruption of page translation tables during resume on x86-64. This is achieved by creating a copy of the relevant page tables that will not be modified by swsusp and can be safely used by it on resume. The problem is that during resume on x86-64 swsusp may temporarily corrupt the page tables used for the direct mapping of RAM. If that happens, a page fault occurs and cannot be handled properly, which leads to the solid hang of the affected system. This leads to the loss of the system's state from before suspend and may result in the loss of data or the corruption of filesystems, so it is a serious issue. Also, it appears to happen quite often (for me, as often as 50% of the time). The problem is related to the fact that (at least) one of the PMD entries used in the direct memory mapping (starting at PAGE_OFFSET) points to a page table the physical address of which is much greater than the physical address of the PMD entry itself. Moreover, unfortunately, the physical address of the page table before suspend (i.e. the one stored in the suspend image) happens to be different to the physical address of the corresponding page table used during resume (i.e. the one that is valid right before swsusp_arch_resume() in arch/x86_64/kernel/suspend_asm.S is executed). Thus while the image is restored, the "offending" PMD entry gets overwritten, so it does not point to the right physical address any more (i.e. there's no page table at the address pointed to by it, because it points to the address the page table has been at during suspend). Consequently, if the PMD entry is used later on, and it _is_ used in the process of copying the image pages, a page fault occurs, but it cannot be handled in the normal way and the system hangs. In principle we can call create_resume_mapping() from swsusp_arch_resume() (ie. from suspend_asm.S), but then the memory allocations in create_resume_mapping(), resume_pud_mapping(), and resume_pmd_mapping() must be made carefully so that we use _only_ NosaveFree pages in them (the other pages are overwritten by the loop in swsusp_arch_resume()). Additionally, we are in atomic context at that time, so we cannot use GFP_KERNEL. Moreover, if one of the allocations fails, we should free all of the allocated pages, so we need to trace them somehow. All of this is done in the appended patch, except that the functions populating the page tables are located in arch/x86_64/kernel/suspend.c rather than in init.c. It may be done in a more elegan way in the future, with the help of some swsusp patches that are in the works now. [AK: move some externs into headers, renamed a function] Signed-off-by: Rafael J.

Miller" Date: Mon, 10 Oct 2005 16:12:13 -0700 Subject: [SPARC64]: Fix Ultra5, Ultra60, et al. boot failures. On the boot processor, we need to do the move onto the Linux trap table a little bit differently else we'll take unhandlable faults in the firmware address space. Previously we would do the following: 1) Disable PSTATE_IE in %pstate. 2) Set %tba by hand to sparc64_ttable_tl0 3) Initialize alternate, mmu, and interrupt global trap registers. 4) Call prom_set_traptable() That doesn't work very well actually with the way we boot the kernel VM these days. It worked by luck on many systems because the firmware accesses for the prom_set_traptable() call happened to be loaded into the TLB already, something we cannot assume. So the new scheme is this: 1) Clear PSTATE_IE in %pstate and set %pil to 15 2) Call prom_set_traptable() 3) Initialize alternate, mmu, and interrupt global trap registers. and this works quite well. This sequence has been moved into a callable function in assembler named setup-trap_table(). The idea is that eventually trampoline.S can use this code as well. That isn't possible currently due to some complications, but eventually we should be able to do it. Thanks to Meelis Roos for the Ultra5 boot failure report. Signed-off-by: David S.

I have fixes for these, but am not comfortable putting them into 2.6.14 at this late date. So, this patch reverts the use of host AIO. I will resubmit the original patch, plus fixes to the driver after 2.6.14 in order to get a reasonable amount of testing before they're exposed to the general public.

However, some (rare & old) CPUs do not have such timebase and it is a bit annoying to have your stuff just crash because you are running on the wrong CPU... This exposes to userland a CPU feature bit that tells that the current processor doesn't have a standard timebase. It's negative logic so that glibc will still "just work" on older kernels (it will just be unhappy on those old CPUs but that doesn't really matter as distro tend to update glibc & kernel at the same time).

Miller" Date: Wed, 12 Oct 2005 12:22:46 -0700 Subject: [SPARC64]: Fix boot failures on SunBlade-150 The sequence to move over to the Linux trap tables from the firmware ones needs to be more air tight. It turns out that to be %100 safe we do need to be able to translate OBP mappings in our TLB miss handlers early. In order not to eat up a lot of kernel image memory with static page tables, just use the translations array in the OBP TLB miss handlers. That solves the bulk of the problem. Furthermore, to make sure the OBP TLB miss path will work even before the fixed MMU globals are loaded, explicitly load %g1 to TLB_SFSR at the beginning of the i-TLB and d-TLB miss handlers. To ease the OBP TLB miss walking of the prom_trans[] array, we sort it then delete all of the non-OBP entries in there (for example, there are entries for the kernel image itself which we're not interested in at all). We also save about 32K of kernel image size with this change. Not a bad side effect :-) There are still some reasons why trampoline.S can't use the setup_trap_table() yet. The most noteworthy are: 1) OBP boots secondary processors with non-bias'd stack for some reason. This is easily fixed by using a small bootup stack in the kernel image explicitly for this purpose. 2) Doing a firmware call via the normal C call prom_set_trap_table() goes through the whole OBP enter/exit sequence that saves and restores OBP and Linux kernel state in the MMUs. This path unfortunately does a "flush %g6" while loading up the OBP locked TLB entries for the firmware call. If we setup the %g6 in the trampoline.S code properly, that is in the PAGE_OFFSET linear mapping, but we're not on the kernel trap table yet so those addresses won't translate properly. One idea is to do a by-hand firmware call like we do in the early bootup code and elsewhere here in trampoline.S But this fails as well, as aparently the secondary processors are not booted with OBP's special locked TLB entries loaded. These are necessary for the firwmare to processes TLB misses correctly up until the point where we take over the trap table. This does need to be resolved at some point. Signed-off-by: David S.

Miller" Date: Fri, 14 Oct 2005 15:26:08 -0700 Subject: [SPARC64]: Fix powering off on SMP. Doing a "SUNW,stop-self" firmware call on the other cpus is not the correct thing to do when dropping into the firmware for a halt, reboot, or power-off. For now, just do nothing to quiet the other cpus, as the system should be quiescent enough. Later we may decide to implement smp_send_stop() like the other SMP platforms do. Based upon a report from Christopher Zimmermann. Signed-off-by: David S.
