* ide: Fix pointer arithmetic in hpt3xx driver code (3rd try)Masoud Sharbiani2008-09-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | git commit 74811f355f4f69a187fa74892dcf2a684b84ce99 causes crash at module load (or boot) time on my machine with a hpt374 controller. The reason for this is that for initializing second controller which sets (hwif->dev == host->dev[1]) to true (1), adds 1 to a void ptr, which advances it by one byte instead of advancing it by sizeof(hpt_info) bytes. Because of this, all initialization functions get corrupted data in info variable which causes a crash at boot time. This patch fixes that and makes my machine boot again. The card itself is a HPT374 raid conroller: Here is the lspci -v output: 03:06.0 RAID bus controller: HighPoint Technologies, Inc. HPT374 (rev 07) Subsystem: HighPoint Technologies, Inc.

PHY events may trigger HSM_ST_ERR with other error codes and, with or without it, there just isn't much reason to do WARN_ON() on it.

Previously, broken hardreset could go unnoticed as it wasn't used during probing but when something goes wrong or after hotplug the problem will surface and bite hard. OSDL bug 11195 reports that sata_nv generic flavor falls into this category. Hardreset itself succeeds but PHY stays offline after hardreset. I tried longer debounce timing but the result was the same. http://bugzilla.kernel.org/show_bug.cgi?id=11195 So, it seems we'll have to drop hardreset from the generic flavor.

Jeff added the Marvell device identifiers to the ahci driver without making the AHCI driver handle the PATA port. This means a lot of users can't use current kernels and in most distro cases can't even install. This has been going on since March 2008 for the 6121 Marvell, and late 2007 for the 6145!!! This was all pointed out at the time and repeatedly ignored. Bugs assigned to Jeff about this are ignored also. To quote Jeff in email > "Just switch the order of 'ahci' and 'pata_marvell' in > /etc/modprobe.conf, then use Fedora's tools regenerate the initrd. > See? It's not rocket science, and the current configuration can be > easily made to work for Fedora users." (Which isn't trivial, isn't end user, shouldn't be needed, and as it usually breaks at install time is in fact impossible) To quote Jeff in August 2007 > " mv-ahci-pata > Marvell 6121/6141 PATA support. Needs fixing in the 'PATA controller > command' area before it is usable, and can go upstream." Only he add the ids anyway later and caused regressions, adding a further id in March causing more regresions. The actual fix for the moment is very simple. If the user has included the pata_marvell driver let it drive the ports. If they've only selected for SATA support give them the AHCI driver which will run the port a fraction faster. Allow the user to control this decision via ahci.marvell_enable as a module parameter so that distributions can ship 'it works' defaults and smarter users (or config tools) can then flip it over it desired.

This results in less pointer hopping when many fingers are on the trackpad. In addition, a finger counting method based on pressure information from all fingers is introduced. Together with a pressure hysteresis window, this yields a more stable counting of the number of fingers on the trackpad.

To fix this issue, expand the check for monotonicity by doing ten consecutive tests instead of one.

On those chipsets, we need to read out the timer value at least three times to get a correct result, for every once in a while (i.e. within a 3 ns window every 69.8 ns) the read returns a bogus result. During normal operation we work around this issue, but during initialization reading a bogus value may lead to -EINVAL even though the hardware is usable.

The problem appears to be that if the adapter is put into D3_hot during ->shutdown(), it cannot be brought back into D0 after kexec (ref. http://marc.info/?l=linux-kernel&m=121900062814967&w=4). Therefore, only put forcedeth into D3 during ->shutdown() if the system is to be powered off. Signed-off-by: Rafael J.

Without this patch only dte irqs are used which may lead to overruns and cases of missing stop and extra bytes being read on the i2c bus. Use of wait irqs forces the hardware to pause and wait until the cpu is ready. Polling is also reworked in this patch to fix ms delay issues.

A future patch will allow for one aerial input to supply both tuners. With the current code, an aerial must be plugged into each antannae input in order for both tuners to function.

Here's a fix. Also change strncpy to strlcpy, as the former is error-prone (and was indeed incorrectly used.)
