* pxafb: Add support for other palette formatsHans J. Koch2007-10-164-16/+68
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for the other three palette formats possible with the PXA LCD controller. This is required on boards where an LCD is connected with all its 18 bits. With this patch, it's possible to use an 8-bit mode with 18-bit palette entries. This used to be possible in 2.4 kernels but disappeared in 2.6. With current kernels, you can only get wrong colours out of an LCD connected this way. Users can choose the palette format by doing something like this in their board definition: static struct pxafb_mach_info my_fb_info = { [...] .lccr3 = LCCR3_OutEnH | LCCR3_PixFlEdg | LCCR3_PDFOR_3, .lccr4 = LCCR4_PAL_FOR_2, [...] }; Signed-off-by: Hans J.

* uvesafb: the driver coreMichal Januszewski2007-10-165-1/+2279
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | uvesafb is an enhanced version of vesafb. It uses a userspace helper (v86d) to execute calls to the x86 Video BIOS functions. The driver is not limited to any specific arch and whether it works on a given arch or not depends on that arch being supported by the userspace daemon. It has been tested on x86_32 and x86_64. A single BIOS call is represented by an instance of the uvesafb_ktask structure. This structure contains a buffer, a completion struct and a uvesafb_task substructure, containing the values of the x86 registers, a flags field and a field indicating the length of the buffer. Whenever a BIOS call is made in the driver, uvesafb_exec() builds a message using the uvesafb_task substructure and the contents of the buffer. This message is then assigned a random ack number and sent to the userspace daemon using the connector interface. The message's sequence number is used as an index for the uvfb_tasks array, which provides a mapping from the messages coming from userspace to the in-kernel uvesafb_ktask structs. The userspace daemon performs the requested operation and sends a reply in the form of a uvesafb_task struct and, optionally, a buffer. The seq and ack numbers in the reply should be exactly the same as those in the request. Each message from userspace is processed by uvesafb_cn_callback() and after passing a few sanity checks leads to the completion of a BIOS call request.

* rtc: fix readback from /sys/class/rtc/rtc?/wakealarmMark Lord2007-10-161-1/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix readback of RTC alarms on platforms which return -1 in non-hardware-supported RTC alarm fields. To fill in the missing (-1) values, we grab an RTC timestamp along with the RTC alarm value, and use the timestamp fields to populate the missing alarm fields. To counter field-wrap races (since the timestamp and alarm are not read together atomically), we read the RTC timestamp both before and after reading the RTC alarm value, and then check for wrapped fields --> if any have wrapped, we know we have a possible inconsistency, so we loop and reread the timestamp and alarm again. Wrapped fields in the RTC timestamps are an issue because rtc-cmos.c, for example, also gets/uses an RTC timestamp internally while fetching the RTC alarm. If our timestamp here wasn't the same (minutes and higher) as what was used internally there, then we might end up populating the -1 fields with inconsistent values. This fixes readbacks from /sys/class/rtc/rtc?/wakealarm, as well as other code paths which call rtc_read_alarm().

* eCryptfs: make open, truncate, and setattr use persistent fileMichael Halcrow2007-10-163-121/+44
| | | | | | | | | | | Rather than open a new lower file for every eCryptfs file that is opened, truncated, or setattr'd, instead use the existing lower persistent file for the eCryptfs inode. Change truncate to use read_write.c functions. Change ecryptfs_getxattr() to use the common ecryptfs_getxattr_lower() function.

| | | | | | | | | | | | Update the metadata read/write functions and grow_file() to use the read_write.c routines. Do not open another lower file; use the persistent lower file instead. Provide a separate function for crypto.c::ecryptfs_read_xattr_region() to get to the lower xattr without having to go through the eCryptfs getxattr.

* eCryptfs: read_write.c routinesMichael Halcrow2007-10-164-2/+379
| | | | | | | | | | | | | | | | | Add a set of functions through which all I/O to lower files is consolidated. This patch adds a new inode_info reference to a persistent lower file for each eCryptfs inode; another patch later in this series will set that up. This persistent lower file is what the read_write.c functions use to call vfs_read() and vfs_write() on the lower filesystem, so even when reads and writes come in through aops->readpage and aops->writepage, we can satisfy them without resorting to direct access to the lower inode's address space. Several function declarations are going to be changing with this patchset. For now, in order to keep from breaking the build, I am putting dummy parameters in for those functions.
