* [PATCH] kernel-docs: fix kernel-doc format problemsRandy Dunlap2005-11-07
| | | | | | | | | | | | | | | Convert to proper kernel-doc format. Some have extra blank lines (not allowed immed. after the function name) or need blank lines (after all parameters). Function summary must be only one line. Colon (":") in a function description does weird things (causes kernel-doc to think that it's a new section head sadly).

* [PATCH] matroxfb: Set maxhipri to 0Ville Syrjälä2005-11-07
| | | | | | | | | | | | | The current init code sets hiprilvl to 0 and maxhipri to 5. According to the specs those values are illegal on both G200 and G400. It also causes distortions on the TV-out at least when CRTC2 is in YUV mode as is the case with DirectFB. This patch resets both values to 0.

* [PATCH] matroxfb: Add support for Mystique AGPVille Syrjälä2005-11-07
| | | | | | | | | | | | | | | | | | | | Add new entries for Mystique AGP with the PCI ID 0x051e. I don't actually have such boards but according to google they do exist. Curiosly X.Org doesn't recognize that PCI ID. And what's even more interesting is that Matrox's own Windows drivers don't recognize it either. After going through about a dozen different versions I did find one older driver that does list this particular ID. It is also listed in the pci.ids file. I'm not sure if non-220 AGP chips exist. I left the chip revision check intact for AGP chips nonetheless. Signed-off-by: Ville Syrjälä <syrjala@sci.fi> Signed-off-by: Petr Vandrovec <petr@vandrovec.name> Cc: "Antonino A.

* [PATCH] fbdev: fix the fb_find_nearest_mode() functionMichal Januszewski2005-11-07
| | | | | | | | | | | | | | | | | | Currently the fb_find_nearest_mode() function finds a mode with screen resolution closest to that described by the 'var' argument and with some arbitrary refresh rate (eg. in the following sequence of refresh rates: 70 60 53 85 75, 53 is selected). This patch fixes the function so that it looks for the closest mode as far as both resolution and refresh rate are concerned. The function's first argument is changed to fb_videomode so that the refresh rate can be specified by the caller, as fb_var_screeninfo doesn't have any fields that could directly hold this data.

* [PATCH] atyfb: Get initial mode timings from LCD BIOSAntonino A. Daplas2005-11-07
| | | | | | | | | | | | | | | | | | | | | | Reported by: Jean-Philippe Guérard (Bugzilla Bug 1782) "I've tried with video=atyfb:debug and video=atyfb:debug,mode:1280x600, \ nomtrr. In both case, the screen stays black, but seems divided into 4 vertical bands. Some white lines pop up randomly on each vertical band." The problem is a combination of an incorrect xclk plus lack of timing information. The adapter is attached to an LCD device that can do 1280x600 (which is not a standard resolution). The global mode database does not have an entry for it. Fortunately, the Video BIOS contains the complete timing info for this display, however, atyfb is not making use of it.

* [PATCH] fbcon/fbdev: Move softcursor out of fbdev to fbconAntonino A. Daplas2005-11-07
| | | | | | | | | | | | | | | | | | | | According to Jon Smirl, filling in the field fb_cursor with soft_cursor for drivers that do not support hardware cursors is redundant. The soft_cursor function is usable by all drivers because it is just a wrapper around fb_imageblit. And because soft_cursor is an fbcon-specific hook, the file is moved to the console directory. Thus, drivers that do not support hardware cursors can leave the fb_cursor field blank. For drivers that do, they can fill up this field with their own version. The end result is a smaller code size. And if the framebuffer console is not loaded, module/kernel size is also reduced because the soft_cursor module will also not be loaded.

It significantly improves the quality of images on the iMac G5 I have here (though the X driver doesn't yet "read" the current value and defaults to 0, so you have to add Option "FBDither" "true" to your X config file to get that, I'll try to fix X.org to "read" the default unless specified asap).

* [PATCH] ipmi: add timer threadCorey Minyard2005-11-07
| | | | | | | | | | | | | | | | | | | | | | | | | We must poll for responses to commands when interrupts aren't in use. The default poll interval is based on using a kernel timer, which varies with HZ. For character-based interfaces like KCS and SMIC though, that can be way too slow (>15 minutes to flash a new firmware with KCS, >20 seconds to retrieve the sensor list). This creates a low-priority kernel thread to poll more often. If the state machine is idle, so is the kernel thread. But if there's an active command, it polls quite rapidly. This decrease a firmware flash time from 15 minutes to 1.5 minutes, and the sensor list time to 4.5 seconds, on a Dell PowerEdge x8x system. The timer-based polling remains, to ensure some amount of responsiveness even under high user process CPU load. Checking for a stopped timer at rmmod now uses atomics and del_timer_sync() to ensure safe stoppage.

* [PATCH] ipmi: kcs error0 delayCorey Minyard2005-11-07
| | | | | | | | | | | | | | | | | | | | | BMCs can get into ERROR0 state while flashing new firmware, particularly while the BMC is erasing the next flash block, which may take a just under 2 seconds on a Dell PowerEdge 2800 (1.75 seconds typical), during which time the single-threaded firmware may not be able to process new commands. In particular, clearing OBF may not take effect immediately. We want it to delay in ERROR0 after clearing OBF a bit waiting for OBF to actually be clear before proceeding. This introduces a new return value from the LLDD's event loop, SI_SM_CALL_WITH_TICK_DELAY. This means the calling thread/timer should schedule_timeout() at least 1 tick, rather than busy-wait. This is a longer delay than SI_SM_CALL_WITH_DELAY, which is typically a 250us busy-wait.

* [PATCH] ipmi: bt restart reset fixesCorey Minyard2005-11-07
| | | | | | | | | | | | | | | | | | | | | | | | | The current BT retry/reset mechanism fails to succeed on a PowerEdge 1650, when the controller is wedged with B2H_ATN asserted at XACTION_START. If this occurs, no further commands will ever succeed unless the state of the controller is first cleared out. Furthermore, the soft reset would only occur if the first command after insmod was the one that timed out, not if a later command timed out. This patch changes the retry/reset mechanism to be as follows: Before retrying a command, clear the state of the BT controller such that the flags represent ready for a new transaction. This increases the chance of success of the restarted transaction. After 2 retries, issue a soft reset and retry one more time before giving up and reporting back a failure.

* [PATCH] ipmi: si start transaction hookCorey Minyard2005-11-07
| | | | | | | | | | | | | | | | | Some commands, on some system BMCs, don't respond at at all. This is seen on Dell PowerEdge x6xx and x7xx systems with IPMI 1.0 BT controllers when a "Get SDR" command is issued, with a length field of 0x3A, which happens to be the length of about SDR entries. If another length is passed, this command succeeds. This patch adds general infrastructure for receiving commands before they're passed down to the low-level drivers, such that they can be completed immediately, or modified, prior to being sent to ->start_transaction().

* [PATCH] ipmi: more dell fixesCorey Minyard2005-11-07
| | | | | | | | | | | | | | | | Make SMIC driver ignore EVT_AVAIL and SMS_ATN bits in flags register, as they're used by systems management interrupts, not the host OS. Make the OEM0 Data Available handler work for pre-IPMI 1.5 systems from Dell too. Without these two fixes, PowerEdge 2650 and other similar systems with SMIC may hang a process (modprobe or anything using /dev/ipmi0).

| | | | | | | | | | | | Make module_param and MODULE_PARAM_DESC agree on poweroff_powercycle name.

* [PATCH] ipmi: watchdog parms in sysfsCorey Minyard2005-11-07
| | | | | | | | | | | Modify the IPMI watchdog parameters (the ones that make sense) to be exported from sysfs. This is somewhat complicated because these parameters have side-effects that must be handled.

* [PATCH] ipmi: various si cleanupCorey Minyard2005-11-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A number of small changes for the various system interface drivers, consolidated from a number of patches from Matt Domsch. Clear B2H_ATN and drain the BMC message buffer on command timeout. This prevents further commands from failing after a timeout. Add bt_debug and smic_debug module parameters, expose them in sysfs. This lets you enable and disable debugging messages at runtime. Unsigned jiffies math in ipmi_si_intf.c causes a too-large value to be passed to ->event() after jiffies wrap-around. The BT driver had caught this, but didn't know how to fix it. Now all calls to ->event() use a sane value for time. Increase timeout for commands handed to the BT driver from 2 seconds to 5 seconds. This is necessary particularly when the previous command was a "Clear SEL", as that command completes, yet the BMC isn't really ready to handle another command yet. Silence BT debugging messages which were being printed on the console. Increase SMIC timeout form 1/10s to 2s. This is needed on Dell PowerEdge 2650 and PowerEdge 750 with ERA/O cards to allow commands to complete without timing out. Adds kcs_debug module param, to match behavior of BT and SMIC. This also prevents messages from being sent to the console unless explicitly requested.
