Now that all ioapic registration happens in mp_register_ioapic we can move the calculation of nr_ioapic_registers there from enable_IO_APIC. The number of ioapic registers is already calucated in mp_register_ioapic so all that really needs to be done is to save the caluclated value in nr_ioapic_registers. Signed-off-by: Eric W.

Long ago MP_ioapic_info was the primary way of setting up our ioapic data structures and mp_register_ioapic was a compatibility shim for acpi code. Now the situation is reversed and and mp_register_ioapic is the primary way of setting up our ioapic data structures. Keep the setting up of ioapic data structures uniform by having mp_register_ioapic call mp_register_ioapic. This changes a few fields: - type: is now hardset to MP_IOAPIC but type had to bey MP_IOAPIC or MP_ioapic_info would not have been called. - flags: is now hard coded to MPC_APIC_USABLE. We require flags to contain at least MPC_APIC_USEBLE in MP_ioapic_info and we don't ever examine flags so dropping a few flags that might possibly exist that we have never used is harmless. - apicaddr: Unchanged - apicver: Read from the ioapic instead of using the cached hardware value in the MP table. The real hardware value will be more accurate. - apicid: Now verified to be unique and changed if it is not. If the BIOS got this right this is a noop. If the BIOS did not fixing things appears to be the better solution. This adds gsi_base and gsi_end values to our ioapics defined with the mpatable, which will make our lives simpler later since we can always assume gsi_base and gsi_end are valid.

Add the global variable gsi_end and teach mp_register_ioapic to keep it uptodate as we add more ioapics into the system. ioapics can only be added early in boot so the code that runs later can treat gsi_end as a constant. Remove the have hacks in sfi.c to second guess mp_register_ioapic by keeping t's own running total of how many gsi's have been seen, and instead use the gsi_end. Signed-off-by: Eric W.

This patches fixes the types of gsi_base and gsi_end values in struct mp_ioapic_gsi, and the gsi parameter of mp_find_ioapic and mp_find_ioapic_pin A gsi is cannonically a u32, not an int.

io_apic_redir_entries has a huge conceptual bug. It returns the maximum redirection entry not the number of redirection entries. Which simply does not match what the name of the function. This just caught me and it caught Feng Tang, and Len Brown when they wrote sfi_parse_ioapic. Modify io_apic_redir_entries to actually return the number of redirection entries, and fix the callers so that they properly handle receiving the number of the number of redirection table entries, instead of the number of redirection table entries less one. While the usage in sfi.c does not show up in this patch it is fixed by virtue of the fact that io_apic_redir_entries now has the semantics sfi_parse_ioapic most reasonably expects.

Remove the assumption that there is not an override for isa irq 0. Instead lookup the gsi and from that lookup the ioapic and pin of each isa irq indivdually. In general this should not have any behavioural affect but in perverse cases this gets all of the details correct, instead of doing something weird. Signed-off-by: Eric W.

Currently acpi_sci_ioapic_setup calls mp_override_legacy_irq with bus_irq == gsi, which is wrong if we are comming from an override Instead pass the bus_irq into acpi_sci_ioapic_setup.

Strictly speaking on x86 (where acpi is used) dev->irq must be a dual i8259 irq input aka an isa irq. Therefore we should translate that isa irq into a gsi before passing it to a function that takes a gsi. Signed-off-by: Eric W.

In perverse acpi implementations the isa irqs are not identity mapped to the first 16 gsi. Furthermore at least the extended interrupt resource capability may return gsi's and not isa irqs. So since what we get from acpi is a gsi teach acpi_get_overrride_irq to operate on a gsi instead of an isa_irq. Signed-off-by: Eric W.

Eric W. Biederman authored
There are a number of cases where the current code makes the assumption that isa irqs identity map to the first 16 acpi global system intereupts. In most instances that assumption is correct as that is the required behaviour in dual i8259 mode and the default behavior in ioapic mode. However there are some systems out there that take advantage of acpis interrupt remapping for the isa irqs to have a completely different mapping of isa_irq to gsi. Introduce acpi_isa_irq_to_gsi to perform this mapping explicitly in the code that needs it. Initially this will be just the current assumed identity mapping to ensure it's introduction does not cause regressions. Signed-off-by: Eric W.

If a rename operation is resent to the MDS following an MDS restart, the client does not get a full reply (containing the resulting metadata) back. In that case, a ceph_rename() needs to compensate by doing anything useful that fill_inode() would have, like d_move(). It also needs to invalidate the dentry (to workaround the vfs_rename_dir() bug) and clear the dir complete flag, just like fill_trace(). Signed-off-by: Sage Weil <sage@newdream.net>

The -mfix-loongson2f-jump option provided by latest CVS binutils have fixed the out-of-order issue of Loongson-2F described in chapter 15 of the Loongson2F User Manual [1, 2], but introduced some problems. The option changes all of the jump target to "addr & 0xcfffffff" through the at($1) register, but for the reboot address of Loongson 2F 0xbfc00000 this is wrong. Avoids the problem via telling the assembler to not use the $at register.

With the "Fixups of Loongson2F" patch [1] having been applied to binutils for binutils 2.20.1 we now can use it's time to enable the options provided by the patch to compile the kernel.

As documented in the Loongson 2F User Manual [2, 3], the old Loongson2F series (2F01 / 2F02) have the NOP & JUMP issues which requires workarounds in the kernel and binutils. This issue has been rectified in Loongson 2F series 2F03 so no workarounds needed. Now that the workarounds [1] adding the the -mfix-loongson2f-nop and -mfix-loongson2f-jump options have been comitted to the binutils the CVS repository), we can add the workarounds in the kernel. The workarounds have no significant side effect on the system but may decrease performance so we control them through a a new CPU_LOONGSON2F_WORKAROUNDS config option allowing the users to only enable it as necessary.
