* [PATCH] ppc64: remove decr_overclockAnton Blanchard2005-06-023-57/+24
| | | | | | | | | | | | | Now that we have HZ=1000 there is much less of a need for decr_overclock. Remove it. Leave spread_lpevents but move it into iSeries_setup.c. We should look at making event spreading the default some day.

* [PATCH] ppc64: cleanup iseries runlight supportAnton Blanchard2005-06-027-36/+33
| | | | | | | | | | | | | | | | | | The iseries has a bar graph on the front panel that shows how busy it is. The operating system sets and clears a bit in the CTRL register to control it. Instead of going to the complexity of using a thread info bit, just set and clear it in the idle loop. Also create two helper functions, ppc64_runlatch_on and ppc64_runlatch_off. Finally don't use the short form of the SPR defines.

* [PATCH] ext3: fix list scanning in __cleanup_transactionJan Kara2005-06-021-1/+0
| | | | | | | | | | | | | | | | | | | | Fix a bug in list scanning that can cause us to skip the last buffer on the checkpoint list (and hence fail to do any progress under some rather unfavorable conditions). The problem is we first do jh=next_jh and then test } while (jh!=last_jh); Hence we skip the last buffer on the list (if it was not the only buffer on the list). As we already do jh=next_jh; in the beginning of the loop we are safe to just remove the assignment in the end. It can happen that 'jh' will be freed at the point we test jh != last_jh but that does not matter as we never *dereference* the pointer.

* [PATCH] ext3: fix log_do_checkpoint() assertion failureJan Kara2005-06-021-1/+3
| | | | | | | | | | | | | | Fix possible false assertion failure in log_do_checkpoint(). We might fail to detect that we actually made a progress when cleaning up the checkpoint lists if we don't retry after writing something to disk. The patch was confirmed to fix observed assertion failures for several users. When we flushed some buffers we need to retry scanning the list. Otherwise we can fail to detect our progress.

| | | | | | | | | | | prom_init(), the trampoline code that "talks" to Open Firmware during early boot, has various issues with managing OF result codes. Some of my recent fixups in fact made the problem worse on some platforms. This patch reworks it all. Tested on g5, Maple, POWER3 and POWER5.

While this seems to work most of the time, there's an ugly deadlock: syscall context is interrupted by the timer interrupt. When the timer interrupt leaves, the timer softirq get's scheduled and calls tcp_delack_timer() and alike. They themselves do bh_lock_sock(sk), which is already held from somewhere else -> boom.

Next, the context allocator is broken. It is highly likely that contexts get used multiple times for different dma mappings, which confuses the strbuf flushing code and makes it run inefficiently.

(As noted by folk whose boards weren't stuck on 2.6.9 kernels...) * Cope with various system-specific issues: - Some configurations (e.g. a CF-card uses this chip) have iospace addresses for the two registers, rather than memory mapped ones. - Some configurations do interesting things with IRQs; maybe the line is shared, or it doesn't support level triggering. - Not all boards can drive the chip reset line in software. * Address a potential race during unlinking. * Tweak probe/remove section info to handle the case where this segment of a platform bus is hotpluggable (e.g. CF card). (The basic problem is that CONFIG_HOTPLUG is global, which is wrong since not all busses can hotplug even on hotplug-friendly systems...) Also export the driver, so that the CF driver can depend on it. Also removed some annoying end-of-line whitespace.

It seems on recent chipset revisions the HSTS_DONE is set only for block transfers, so we must detect the end of ordinary transaction other way. Also due to missing and mask, setting other transfer modes was not possible. Moreover the continous byte mode transfer uses DAT0 for command rather than CMD command. All those changes were tested with help of Chunhao Huang from Winbond. I'm willing to maintain the driver. Second patch adds me as maintainer if this is neccessary.

Changes include: - cpci_enable_device and its recursive calling of pci_enable_device on new devices removed. - Use list_rwsem to avoid slot status change races between disable_slot and check_slots. - Fixed oopsing in cpci_hp_unregister_bus caused by calling list_del on a slot after calling pci_hp_deregister. - Removed kfree calls in cleanup_slots since release_slot will have done it already. - Reworked init_slots a bit to fix latch and adapter file updating on subsequent calls to cpci_hp_start. - Improved sanity checking in cpci_hp_register_controller. - Now shut things down correctly in cpci_hotplug_exit. - Switch to pci_get_slot instead of deprecated pci_find_slot. - A bunch of CodingStyle fixes.

It does the following things: - Workaround an issue in some Apple device-trees where a property may exist with the same name as a child node of the parent. We now simply "drop" the property instead of creating duplicate entries in /proc with random result... - Do not try to chop off the "@0" at the end of a node name whose unit address is 0. This is not useful, inconsistent, and the code was buggy and didn't always work anyway. - Do not create symlinks for the short name and unit address parts of a node. These were never really used, bloated the memory footprint of the device-tree with useless struct proc_dir_entry and their matching dentry and inode cache bloat. This results in smaller code, smaller memory footprint, and a more accurate view of the tree presented to userland.

The optimal frequency being the lowest frequency which provides enough power to not trigger the upscaling policy.
