* [POWERPC] fsl: Update fsl_soc to use cell-index property of I2C nodesTimur Tabi2008-06-021-2/+8
| | | | | | | | | | | | Currently, fsl_i2c_of_init() uses the order of the I2C adapter nodes in the device tree to enumerate the I2C adapters. Instead, let's check for the cell-index property and use it if it exists. This is handy for device drivers that need to identify the I2C adapters by specific numbers. The Freescale MPC8610 ASoC V2 sound drivers are an example. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* [POWERPC] 40x/Book-E: Save/restore volatile exception registersKumar Gala2008-06-024-3/+174
| | | | | | | | | | | | | | | | | | | | | On machines with more than one exception level any system register that might be modified by the "normal" exception level needs to be saved and restored on taking a higher level exception. We already are saving and restoring ESR and DEAR. For critical level add SRR0/1. For debug level add CSRR0/1 and SRR0/1. For machine check level add DSRR0/1, CSRR0/1, and SRR0/1. On FSL Book-E parts we always save/restore the MAS registers for critical, debug, and machine check level exceptions. On 44x we always save/restore the MMUCR. Additionally, we save and restore the ksp_limit since we have to adjust it for each exception level. Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Acked-by: Paul Mackerras <paulus@samba.org>

* [POWERPC] Move to runtime allocated exception stacksKumar Gala2008-06-027-50/+85
| | | | | | | | | | | | | For the additonal exception levels (critical, debug, machine check) on 40x/book-e we were using "static" allocations of the stack in the associated head.S. Move to a runtime allocation to make the code a bit easier to read as we mimic how we handle IRQ stacks. Its also a bit easier to setup the stack with a "dummy" thread_info in C code.

| | | | | | | | | | | | | | | | | | | | This MSI driver can be used on 83xx/85xx/86xx board. In this driver, virtual interrupt host and chip were setup. There are 256 MSI interrupts in this host, Every 32 MSI interrupts cascaded to one IPIC/MPIC interrupt. The chip was treated as edge sensitive and some necessary functions were setup for this chip. Before using the MSI interrupt, PCI/PCIE device need to ask for a MSI interrupt in the 256 MSI interrupts. A 256bit bitmap show which MSI interrupt was used, reserve bit in the bitmap can be used to force the device use some designate MSI interrupt in the 256 MSI interrupts. Sometimes this is useful for testing the all the MSI interrupts. The msi-available-ranges property in the dts file was used for this purpose.

* [POWERPC] Convert remaining dts-v0 files to v1David Gibson2008-05-2917-1310/+1344
| | | | | | | | | | | | | | | | | | | | At the moment we have a mixture of left-over version 0 and new-format version 1 files in arch/powerpc/boot/dts. This is potentially confusing to people new to the dts format attempting to figure it out. So, this patch converts all the as-yet unconverted dts v0 files and converts them to v1. They're mechanically-converted, and not hand tweaked so in some cases they're not 100% in keeping with usual v1 style, but the convertor program does have some heuristics so the discrepancies aren't too bad. I have checked that this patch produces no changes to the resulting dtb binaries.

* [POWERPC] Refactor DCR codeStephen Neuendorffer2008-05-295-47/+231
| | | | | | | | | | | | | | | | | | | | | Previously, DCR support was configured at compile time to either use MMIO or native dcr instructions. Although this works for most platforms, it fails on FPGA platforms: 1) Systems may include more than one DCR bus. 2) Systems may be native DCR capable and still use memory mapped DCR interface. This patch provides runtime support based on the device trees for the case where CONFIG_PPC_DCR_MMIO and CONFIG_PPC_DCR_NATIVE are both selected. Previously, this was a poorly defined configuration, which happened to provide NATIVE support. The runtime selection is made based on the dcr-controller having a 'dcr-access-method' attribute in the device tree. If only one of the above options is selected, then the code uses #defines to select only the used code in order to avoid introducing overhead in existing usage.

The default value of retries1 is 3. So if the path mtu changes and ICMP frag needed is lost for the first 3 retransmits or if it gets delayed until 3 retransmits are done, TCP doesn't update MSS correctly and continues to retransmit the orginal message until it timesout after tcp_retries2 retransmits. I am seeing this issue even with the latest 2.6.25.4 kernel. In tcp_retransmit_timer(), when retransmits counter exceeds tcp_retries1 value, the dst cache entry of the socket is reset. At this time, if we receive an ICMP frag needed message, the dst entry gets updated with the new MTU, but the TCP sockets dst_cache entry remains NULL. So the next time when we try to retransmit after the ICMP frag needed is received, tcp_retransmit_skb() gets called. Here the cur_mss value is calculated at the start of the routine with a NULL sk_dst_cache. Instead we should call tcp_current_mss after the rebuild_header that caches the dst entry with the updated mtu. Also the rebuild_header should be called before tcp_fragment so that skb is fragmented if the mss goes down. Signed-off-by: Sridhar Samudrala <sri@us.ibm.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In ath5k_tasklet_rx, both status structures 'rxs' and 'rs' are initialized at the top of the tasklet, but not within the loop. If the loop is executed multiple times in the tasklet then the variables may see changes from previous packets. For TKIP, this results in 'Invalid Michael MIC' errors if two packets are processed in the tasklet: rxs.flag gets set to RX_DECRYPTED by mac80211 when it decrypts the first encrypted packet. The subsequent packet will have RX_DECRYPTED set upon entry to mac80211, so mac80211 will not try to decrypt it. We currently initialize all but two fields in the structures, so fix the other two.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The offset to the pt_regs area was wrong, so we weren't looking at the right location for the magic cookie. A trap frame is composed of a "struct sparc_stackf" then a "struct pt_regs", the code was using "struct reg_window" instead of "struct sparc_stackf". Signed-off-by: David S.
