* [TCP]: Add Scalable TCP congestion control module.John Heffner2005-06-23
| | | | | | | | | | | | This patch implements Tom Kelly's Scalable TCP congestion control algorithm for the modular framework. The algorithm has some nice scaling properties, and has been used a fair bit in research, though is known to have significant fairness issues, so it's not really suitable for general purpose use.

* [TCP]: Add H-TCP congestion control module.Baruch Even2005-06-23
| | | | | | | | | | | | | | | | | | H-TCP is a congestion control algorithm developed at the Hamilton Institute, by Douglas Leith and Robert Shorten. It is extending the standard Reno algorithm with mode switching is thus a relatively simple modification. H-TCP is defined in a layered manner as it is still a research platform. The basic form includes the modification of beta according to the ratio of maxRTT to min RTT and the alpha=2*factor*(1-beta) relation, where factor is dependant on the time since last congestion. The other layers improve convergence by adding appropriate factors to alpha. The following patch implements the H-TCP algorithm in it's basic form.

* [TCP]: Add TCP Hybla congestion control module.Daniele Lacamera2005-06-23
| | | | | | | | | | | | | | | | | | | | | | TCP Hybla congestion avoidance. - "In heterogeneous networks, TCP connections that incorporate a terrestrial or satellite radio link are greatly disadvantaged with respect to entirely wired connections, because of their longer round trip times (RTTs). To cope with this problem, a new TCP proposal, the TCP Hybla, is presented and discussed in the paper[1]. It stems from an analytical evaluation of the congestion window dynamics in the TCP standard versions (Tahoe, Reno, NewReno), which suggests the necessary modifications to remove the performance dependence on RTT.[...]"[1] [1]: Carlo Caini, Rosario Firrincieli, "TCP Hybla: a TCP enhancement for heterogeneous networks", International Journal of Satellite Communications and Networking Volume 22, Issue 5 , Pages 547 - 566.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently reset and powerdown are not implemented on the Maple board, and attempting to do so will (incorrectly return). This implements the proper communication with the service processor, allowing correct reset and powerdown on the Maple board, by communicating with the service processor. If somehow it's unable to communicate with the service processor it will loop forever instead. Note that powerdown on the Maple will power down the CPUs, but not the fans or other board components due to hardware and firmware limitations.

| * [PATCH] pSeries - read irqs dynamicallyJohn Rose2005-06-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For I/O DLPAR to work properly, the kernel needs to allow for dynamic assignment of the irq field of the pci_dev structure upon dynamic bus addition. This patch moves the assignment of that field from pSeries_final_fixup() to pcibios_fixup_bus(), which enables dynamic assignment for the children of a newly added bus. Currently, pci_devs receive their irq numbers in one of two ways. The irq line is either read at boot for all pci_devs, or read by the rpaphp module at slot enable time. The latter is no longer sufficient for DLPAR addition of slots that don't qualify as PCI-hotplug capable. This solution handles the cases of boot and dynamic add.

| * [PATCH] correct printing to operator panelMike Strosaker2005-06-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch corrects the printing of progress indicators to the op panel on p/iSeries ppc64 systems. Each discrete reference code should begin with a form feed char to clear the op panel, and the first and second lines should be separated with a CR/LF sequence. Padding with spaces is not necessary. Also, capitalize the hex value printed on the first line, to be consistent with the values printed by firmware, service processor, etc. It turns out that there's an ibm,form-feed property; this patch uses it in the pSeries-specific progress routine. This patch also checks the number of rows and the specific width of each row (the second row on power5 systems can actually hold 80 characters). If the displayed text is too wide for the physical display, it can be viewed in the ASM menus, or by selecting option 14 on the op panel.

| * [PATCH] ppc64: Add driver for BPA iommuArnd Bergmann2005-06-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implementation of software load support for the BE iommu. This is very different from other iommu code on ppc64, since we only do a static mapping. The mapping is currently hardcoded but should really be read from the firmware, but they don't set up the device nodes yet. There is a single 512MB DMA window for PCI, USB and ethernet at 0x20000000 for our RAM. The Cell processor can put the I/O page table either in memory like the hashed page table (hardware load) or have the operating system write the entries into memory mapped CPU registers (software load). I use the software load mechanism because I know that all I/O page table entries for the amount of installed physical memory fit into the IO TLB cache. At the point when we get machines with more than 4GB of installed memory, we can either use hardware I/O page table access like the other platforms do or dynamically update the I/O TLB entries when a page fault occurs in the I/O subsystem. The software load can then use the macros that I have implemented for the static mapping in order to do the TLB cache updates.

| * [PATCH] ppc64: Add driver for BPA interrupt controllersArnd Bergmann2005-06-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for the integrated interrupt controller on BPA CPUs. There is one of those for each SMT thread. The mapping of interrupt numbers to HW interrupt sources is described in arch/ppc64/kernel/bpa_iic.h. This version hardcodes the 'Spider' chip as the secondary interrupt controller. That is not really generic for the architecture, but at the moment it is the only secondary PIC that exists. A little more work will be needed on this as soon as we have boards with multiple external interrupt controllers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a watchdog using the RTAS OS surveillance service. This is provided as a simpler alternative to rtasd. The added value is that it works with standard watchdog client programs and can therefore also do user space monitoring. On BPA, rtasd is not really useful because the hardware does not have much to report with event-scan. The driver should also work on other platforms that support the OS surveillance rtas calls.

| * [PATCH] ppc64: pSeries_progress -> rtas_progressArnd Bergmann2005-06-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The pSeries_progress function is called from some places in the rtas code, which may also be used by non-pSeries platforms. Though pSeries is currently the only platform type that implements display-character, the code is actually generic enough to be part of the rtas subsystem. I hit a bug here because the generic rtas code tried calling ppc_md.progress, which points to an __init function on most platforms. We could also clear the ppc_md.progress pointer when freeing the init memory to make it more explicit that ppc_md.progress must not be called after bootup.

Instead, I'm moving the code to arch/ppc64/kernel/time.c. Some of the related declarations were missing from header files, so I'm moving those as well.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current ide-cd driver reports the CDROM speed (as found in /proc/sys/dev/cdrom/info) as the current speed when loading the driver. Changing the speed of the cdrom drive (by "eject -x" for instance) doesn't update the speed reported by the kernel. Updating the info could be valuable for the user as it's the only way to know if the drive accepted the request or discarded it. It could even be used to list all the available speeds of the drive. The attached patch modifies the ide-cd driver so that after every speed change request the new speed is updated. Please note that the actual modification is very little but I had to touch quite a few lines in order to avoid to pre-declare the sub-functions.

* | [PATCH] Bug in error recovery in fs/buffer.c::__block_prepare_write()Anton Altaparmakov2005-06-23

It calls the get_block() callback with "create = 1" and if that succeeds it immediately clears buffer_new on the just allocated buffer (which has buffer_new set). The bug is that if an error occurs and get_block() returns != 0, we break from this loop and go into recovery code. This code has this comment: /* Error case: */ /* * Zero out any newly allocated blocks to avoid exposing stale * data. If BH_New is set, we know that the block was newly * allocated in the above loop. */ So the intent is obviously good in that it wants to clear just allocated and hence not zeroed buffers. However the code recognises allocated buffers by checking for buffer_new being set. Unfortunately __block_prepare_write() as discussed above already cleared buffer_new on all allocated buffers thus no buffers will be cleared during error recovery and old data will be leaked. The simplest way I can see to fix this is to make the current recovery code work by _not_ clearing buffer_new after calling get_block() in __block_prepare_write(). We cannot safely allow buffer_new buffers to "leak out" of __block_prepare_write(), thus we simply do a quick loop over the buffers clearing buffer_new on each of them if it is set just before returning "success" from __block_prepare_write().

As a side note, I found that compat_blkdev_ioctl() acquires the BKL as well, which looks like a bug.

* | [PATCH] ipcsem: remove superflous decrease variable from sys_semtimedopManfred Spraul2005-06-23
| | | | | | | | | | | | | | | | | | | | | | | | Patrick noticed that the initial scan of the semaphore operations logs decrease and increase operations seperately, but then both cases are or'ed together and decrease is never used. The attached patch removes the decrease parameter - it shrinks sys_semtimedop() by 56 bytes.

* | [PATCH] Turn off sibling call optimization w/ frame pointersMatthias Urlichs2005-06-23
| | | | | | | | | | | | | | | | | | | | | | | | Frame pointers are supposed to enable debuggers to reliably tell where a call comes from. That is defeated by GCC's sibling call optimization (aka tail recursion elimination). This patch turns this optimization off when compiling with frame pointers.

* | [PATCH] Optimize sys_times for a single thread processChristoph Lameter2005-06-23
| | | | | | | | | | | | | | | | | | | | | | | | Avoid taking the tasklist_lock in sys_times if the process is single threaded. In a NUMA system taking the tasklist_lock may cause a bouncing cacheline if multiple independent processes continually call sys_times to measure their performance.
