| * | x86, SGI UV: hardcode the TLB flush interrupt system vectorCliff Wickman2008-08-201-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The UV TLB shootdown mechanism needs a system interrupt vector. Its vector had been hardcoded as 200, but needs to moved to the reserved system vector range so that it does not collide with some device vector. This is still temporary until dynamic system IRQ allocation is provided. But it will be needed when real UV hardware becomes available and runs 2.6.27.

The reason is this commit: > commit f25f64ed5bd3c2932493681bdfdb483ea707da0a > Author: Juergen Beisert <juergen@kreuzholzen.de> > Date: Sun Jul 22 11:12:38 2007 +0200 > > x86: Replace NSC/Cyrix specific chipset access macros by inlined functions. this commit activated a macro which was dormant before due to (buggy) macro side-effects. I've looked through various datasheets and found that the GXm and GXLV Geode processors don't have an incrementor. Remove the incrementor setup entirely. As the incrementor value differs according to clock speed and we would hope that the BIOS configures it correctly, it is probably the right solution.

Fortunately this function is only used by ext4. The function uses ffs which does not work analog to ffz. The result of ffs has an offset of 1 which is not taken into account. To fix this use the low level __ffs_word function directly instead of the ill defined ffs. In addition the patch improves find_next_zero_bit and ext2_find_next_zero_bit by passing the bit offset into __ffz_word instead of adding it after the function call returned.

This fixes it by avoiding the vio_cmo_bus_remove call on platforms that don't implement CMO. cpu 0x0: Vector: 300 (Data Access) at [c00000000e13b3d0] pc: c000000000020d34: .vio_cmo_bus_remove+0xc0/0x1f4 lr: c000000000020ca4: .vio_cmo_bus_remove+0x30/0x1f4 sp: c00000000e13b650 msr: 8000000000009032 dar: 0 dsisr: 40000000 current = 0xc00000000e0566c0 paca = 0xc0000000006f9b80 pid = 2428, comm = modprobe enter ? for help [c00000000e13b6e0] c000000000021d94 .vio_bus_probe+0x2f8/0x33c [c00000000e13b7a0] c00000000029fc88 .driver_probe_device+0x13c/0x200 [c00000000e13b830] c00000000029fdac .__driver_attach+0x60/0xa4 [c00000000e13b8c0] c00000000029f050 .bus_for_each_dev+0x80/0xd8 [c00000000e13b980] c00000000029f9ec .driver_attach+0x28/0x40 [c00000000e13ba00] c00000000029f630 .bus_add_driver+0xd4/0x284 [c00000000e13baa0] c0000000002a01bc .driver_register+0xc4/0x198 [c00000000e13bb50] c00000000002168c .vio_register_driver+0x40/0x5c [c00000000e13bbe0] d0000000003b3f1c .ibmvfc_module_init+0x70/0x109c [ibmvfc] [c00000000e13bc70] c0000000000acf08 .sys_init_module+0x184c/0x1a10 [c00000000e13be30] c000000000008748 syscall_exit+0x0/0x40 Signed-off-by: Brian King <brking@linux.vnet.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

This is a user-visible regression which breaks the userspace eHCA support, since the eHCA userspace driver relies on the name attribute to check for valid adapters. This fixes it by providing the "name" attribute in the generic OF device code instead. Tested on POWER.

Currently, there is a possible reference-after-free in the spusched code - contexts may be freed after we have released their state_mutex in spusched_tick and find_victim. This change takes a reference to the context before releasing the mutex, so that the context doesn't get destroyed. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>

While this is correct for isolated contexts, there's no need to enforce the npc restriction on non-isolated NOSCHED contexts. This means that NOSCHED contexts can only ever run with an entry point of 0x0. This change to spu_run_init allows setting of the npc (and, while we're at it, the privcntl) for non-isolated NOSCHED contexts. This allows us to run NOSCHED contexts from any entry point.

Nevertheless it's possible for Linux to be more resolent about this situation (and similar situations) and work around this bug, by cross-checking the mmconf range against the e820 table and ACPI resources. Change the mconf bus range from [0,0xff] to to [0, 0x3f] to match range [0xf0000000, 0xf4000000) in e820 tables.
