| * | | | | [POWERPC] 83xx: Make 83xx perfmon support selectableAndy Fleming2008-03-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Not all e300 cores support the performance monitors, and the ones that don't will be confused by the mf/mtpmr instructions. This allows the support to be optional, so the 8349 can turn it off while the 8379 can turn it on. Sadly, those aren't config options, so it will be left to the defconfigs and the users to make that determination.

It was supposed to be a relatively small pool, but as demonstrated by KOSAKI Motohiro, they can grow as large as: Quicklists: 1194304 kB given how much trouble this code has caused historically, and given that Andrew objected to its introduction on x86 (years ago), the best option at this point is to remove them.

* | | | | x86: ia32 syscall restart fixRoland McGrath2008-03-11

These fields are 64 bits and for a 32-bit task they get zero-extended. The syscall restart behavior is lost, a regression from a native 32-bit kernel and from 64-bit tasks' behavior. This patch fixes the problem by doing sign-extension where it matters. For orig_ax, the only time the value should be -1 but winds up as 0x0ffffffff is via a 32-bit ptrace call. So the patch changes ptrace to sign-extend the 32-bit orig_eax value when it's stored; it doesn't change the checks on orig_ax, though it uses the new current_syscall() inline to better document the subtle importance of the used of signedness there. The ax value is stored a lot of ways and it seems hard to get them all sign-extended at their origins. So for that, we use the current_syscall_ret() to sign-extend it only for 32-bit tasks at the time of the -ERESTART* comparisons.

But this commit fixes a real bug so the real question is, why did it break the bootup? After quite some head-scratching, the following change stood out: - pci_id->bus = tu8; + pci_id->bus = val; pci_id->bus is defined as u16: struct acpi_pci_id { u16 segment; u16 bus; ... and 'tu8' changed from u8 to u32. So previously we'd unconditionally mask the return value of acpi_os_read_pci_configuration() (raw_pci_read()) to 8 bits, but now we just trust whatever comes back from the PCI access routines and only crop it to 16 bits. But if the high 8 bits of that result contains any noise then we'll write that into ACPI's PCI ID descriptor and confuse the heck out of the rest of ACPI. So lets check the PCI-BIOS code on that theory. We have this codepath for 8-bit accesses (arch/x86/pci/pcbios.c:pci_bios_read()): switch (len) { case 1: __asm__("lcall *(%%esi); cld\n\t" "jc 1f\n\t" "xor %%ah, %%ah\n" "1:" : "=c" (*value), "=a" (result) : "1" (PCIBIOS_READ_CONFIG_BYTE), "b" (bx), "D" ((long)reg), "S" (&pci_indirect)); Aha! The "=a" output constraint puts the full 32 bits of EAX into *value. But if the BIOS's routines set any of the high bits to nonzero, we'll return a value with more set in it than intended. The other, more common PCI access methods (v1 and v2 PCI reads) clear out the high bits already, for example pci_conf1_read() does: switch (len) { case 1: *value = inb(0xCFC + (reg & 3)); which explicitly converts the return byte up to 32 bits and zero-extends it. So zero-extending the result in the PCI-BIOS read routine fixes the regression on my laptop. ( It might fix some other long-standing issues we had with PCI-BIOS during the past decade ... ) Both 8-bit and 16-bit accesses were buggy.

The bug was that handing a 0 as the address of the toplevel page table being manipulated can cause the lookup code in find_pgdir() to return an uninitialized cache entry (we shadow up to 4 top level page tables for each Guest). Commit 37cc8d7f963ba2deec29c9b68716944516a3244f introduced this behaviour in the Guest, uncovering the bug. The patch which he submitted (which removed the /4 from the index calculation) simply ensured that these high-indexed entries hit the early exit path of guest_set_pmd(). But you get lots of segfaults in guest userspace as the PMDs aren't being updated. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

* | | | x86_64: make ptrace always sign-extend orig_ax to 64 bitsRoland McGrath2008-03-07

This matches what a 64-bit debugger expects when tracing a 32-bit task. This follows on my "x86_64 ia32 syscall restart fix". This didn't matter until that was fixed. The debugger ignores or zeros the high half of every register slot it sets (including the orig_rax pseudo-register) uniformly. It expects that the setting of the low 32 bits always has the same meaning as a 32-bit debugger setting those same 32 bits with native 32-bit facilities. This never arose before because the syscall restart check never matched any -ERESTART* values due to lack of sign extension. Before that fix, even 32-bit ptrace setting orig_eax to -1 failed to trigger the restart check anyway. So this was never noticed as a regression of 64-bit debuggers vs 32-bit debuggers on the same 64-bit kernel.

After debugging it, it turned out to be caused by the fact that the vesa probing now asks for VBE2 data. Disassembing the video BIOS shows that it overflows the vesa_general_info structure when VBE2 data is requested because the source addresses for the information strings which get strcpy'ed to the buffer lie outside the 32K BIOS code (and hence contain long sequences of 0xff's).

The old setup code didn't ask for VBE2 info, and the new code doesn't actually do anything with the extra information, so the fix is to simply not request it.

[ mingo@elte.hu: we encode it this way because there's no space for the 'FPU Last Instruction Opcode' (->fop) field in the legacy user_i387_ia32_struct that PTRACE_GETFPREGS/PTRACE_SETFPREGS uses. it's probably pure legacy - i'd be surprised if any user-space relied on the FPU Last Opcode in any way. But indeed we used to do it previously so the most conservative thing is to preserve that piece of information. ] Signed-off-by: Jan Beulich <jbeulich@novell.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Linux kernel currently does not clear the direction flag before calling a signal handler, whereas the x86/x86-64 ABI requires that. Linux had this behavior/bug forever, but this becomes a real problem with gcc version 4.3, which assumes that the direction flag is correctly cleared at the entry of a function. This patches changes the setup_frame() functions to clear the direction before entering the signal handler.
