2010-02-27Bluetooth: Convert controller hdev->type to hdev->busMarcel Holtmann15-25/+25
The hdev->type is misnamed and should be actually hdev->bus instead. So convert it now. Signed-off-by: Marcel Holtmann <[email protected]>

2010-02-27Bluetooth: Make USB device id constantMárton Németh1-1/+1
The id_table field of the struct usb_device_id is constant in <linux/usb.h> so it is worth to make bcm203x_table also constant. The semantic match that finds this kind of pattern is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ disable decl_init,const_decl_init; identifier I1, I2, x; @@ struct I1 { ... const struct I2 *x; ... }; @s@ identifier r.I1, y; identifier r.x, E; @@ struct I1 y = { .x = E, }; @c@ identifier r.I2; identifier s.E; @@ const struct I2 E[] = ... ; @depends on !c@ identifier r.I2; identifier s.E; @@ + const struct I2 E[] = ...; // </smpl> Signed-off-by: Márton Németh <[email protected]> Cc: Julia Lawall <[email protected]> Cc: [email protected] Signed-off-by: Marcel Holtmann <[email protected]>

2010-02-27MIPS: Cobalt: convert legacy port addresses to GT-64111 bus addressesBjorn Helgaas2-2/+61
The GT-64111 PCI host bridge has no address translation mechanism, so it can't generate legacy port accesses. This quirk fixes legacy device port resources to contain the bus addresses actually generated by the GT-64111. I think this is the approach Ben Herrenschmidt suggested long ago: http://marc.info/?l=linux-kernel&m=119733290624544&w=2 This allows us to remove the IORESOURCE_PCI_FIXED hack from pcibios_fixup_device_resources(), which converts bus addresses to CPU addresses. IORESOURCE_PCI_FIXED denotes resources that can't be moved; it has nothing to do with converting bus to CPU addresses.

2010-02-27MIPS: Alchemy: use 36bit addresses for PCMCIA resources.Manuel Lauss16-177/+123
On Alchemy the PCMCIA area lies at the end of the chips 36bit system bus area. Currently, addresses at the far end of the 32bit area are assumed to belong to the PCMCIA area and fixed up to the real 36bit address before being passed to ioremap(). A previous commit enabled 64 bit physical size for the resource datatype on Alchemy and this allows to use the correct 36bit addresses when registering the PCMCIA sockets. This patch removes the 32-to-36bit address fixup and registers the Alchemy demo board pcmcia socket with the correct 36bit physical addresses. Tested on DB1200, with a CF card (ide-cs driver) and a 3c589 PCMCIA ethernet card.

2010-02-27MIPS: Cobalt: Fix theoretical port aliasing issueRalf Baechle1-1/+1
Because the VIA SuperIO chip only decodes 24 bits of address space but port address space currently being configured as 32MB there is the theoretical possibility of aliases within the I/O port address range. The complicated solution is to reserve all address range that potencially could cause such aliases. But with the PCI spec limiting port allocations for devices to a maximum of 256 bytes 16MB of port address space already is way more than one would ever expect to be used so we just reduce the port space to 16MB.

2010-02-27MIPS: Crazy spinlock speed test.David Daney3-0/+149
This is just a test program for raw_spinlocks. The main reason I wrote it is to validate my spinlock changes that I sent in a previous patch. To use it enable CONFIG_DEBUG_FS and CONFIG_SPINLOCK_TEST then at run time do: # mount -t debugfs none /sys/kernel/debug/ # cat /sys/kernel/debug/mips/spin_single # cat /sys/kernel/debug/mips/spin_multi On my 600MHz octeon cn5860 (16 CPUs) I get spin_single spin_multi base 106885 247941 spinlock_patch 75194 219465 This shows that for uncontended locks the spinlock patch gives 41% improvement and for contended locks 12% improvement (1/time).

2010-02-27MIPS: Optimize spinlocks.David Daney3-81/+67
The current locking mechanism uses a ll/sc sequence to release a spinlock. This is slower than a wmb() followed by a store to unlock. The branching forward to .subsection 2 on sc failure slows down the contended case. So we get rid of that part too. Since we are now working on naturally aligned u16 values, we can get rid of a masking operation as the LHU already does the right thing. The ANDI are reversed for better scheduling on multi-issue CPUs On a 12 CPU 750MHz Octeon cn5750 this patch improves ipv4 UDP packet forwarding rates from 3.58*10^6 PPS to 3.99*10^6 PPS, or about 11%.

Change to different macros for assembler macros since the old names in powertv_setup.c were co-opted for use in asm/asm.h. This broken the build for the powertv platform.

2010-02-27Staging: Octeon: Free transmit SKBs in a timely mannerDavid Daney6-63/+142
If we wait for the once-per-second cleanup to free transmit SKBs, sockets with small transmit buffer sizes might spend most of their time blocked waiting for the cleanup. Normally we do a cleanup for each transmitted packet. We add a watchdog type timer so that we also schedule a timeout for 150uS after a packet is transmitted. The watchdog is reset for each transmitted packet, so for high packet rates, it never expires. At these high rates, the cleanups are done for each packet so the extra watchdog initiated cleanups are neither needed nor triggered.
