* [PATCH] EFI: keep physical table addresses in efi structureBjorn Helgaas2006-03-262-21/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | Almost all users of the table addresses from the EFI system table want physical addresses. So rather than doing the pa->va->pa conversion, just keep physical addresses in struct efi. This fixes a DMI bug: the efi structure contained the physical SMBIOS address on x86 but the virtual address on ia64, so dmi_scan_machine() used ioremap() on a virtual address on ia64. This is essentially the same as an earlier patch by Matt Tolentino: http://marc.theaimsgroup.com/?l=linux-kernel&m=112130292316281&w=2 except that this changes all table addresses, not just ACPI addresses. Matt's original patch was backed out because it caused MCAs on HP sx1000 systems. That problem is resolved by the ioremap() attribute checking added for ia64.

* [PATCH] dcdbas: convert to the new platform device interfaceDmitry Torokhov2006-03-221-22/+88
| | | | | | | | | | | | | | Do not use platform_device_register_simple() as it is going away, define dcdbas_driver and implement ->probe() and ->remove() functions so manual binding and unbinding will work with this driver. Also switch to using attribute_group when creating sysfs attributes and make sure to check and handle errors; explicitely remove attributes when detaching driver.

* [PATCH] dell_rbu: fix Bug 5854Abhay Salunke2006-01-151-22/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes http://bugzilla.kernel.org/show_bug.cgi?id=5854 Root cause: The dell_rbu driver creates entries in /sys/class/firmware/dell_rbu/ by calling request_firmware_nowait (without hotplug ) this function inturn starts a kernel thread which creates the entries in /sys/class/firmware/dell_rbu/loading , data and the thread waits on the user action to return control back to the callback fucntion of dell_rbu. The thread calls wait_on_completion which puts it in a D state until the user action happens. If there is no user action happening the load average goes up as the thread D state is taken in to account. Also after downloading the BIOS image the enrties go away momentarily but they are recreated from the callback function in dell_rbu. This causes the thread to get recreated causing the load average to permenently stay around 1. Fix: The dell_rbu also creates the entry /sys/devices/platform/dell_rbu/image_type at driver load time. The image type by default is mono if required the user can echo packet to image_type to make the BIOS update mechanism using packets. Also by echoing init in to image_type the /sys/class/firmware/dell_rbu entries can be created. The driver code was changed to not create /sys/class/firmware/dell_rbu entries during load time, and also to not create the above entries from the callback function. The entries are only created by echoing init to /sys/devices/platform/dell_rbu/image_type The user now needs to create the entries to download the image monolithic or packet. This fixes the issue since the kernel thread only is created when ever the user is ready to download the BIOS image; this minimizes the life span of the kernel thread and the load average goes back to normal.

* [PATCH] dell_rbu: Adding BIOS memory floor supportAbhay Salunke2005-11-071-26/+95
| | | | | | | | | | | | | | | | | | This patch has the changes to support the memory floor fix done in Dell BIOS. The BIOS incase of packet update mechanism would not accept packet placed in memory below a cretain address. This address is by default 128K but can change. The driver now can accept the memory floor if the user chooses to make it will try to allocate contiguous physical memory above the memory floor by allocating a set of packets till a valid memory allocation is made. All the allocates then are freed. This repeats for everty packet.

* [PATCH] dell_rbu: changes in packet update mechanismAbhay Salunke2005-10-111-81/+93
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the current dell_rbu code ver 2.0 the packet update mechanism makes the user app dump every individual packet in to the driver. This adds in efficiency as every packet update makes the /sys/class/firmware/dell_rbu/loading and data files to disappear and reappear again. Thus the user app needs to wait for the files to reappear to dump another packet. This slows down the packet update tremendously in case of large number of packets. I am submitting a new patch for dell_rbu which will change the way we do packet updates; In the new method the user app will create a new single file which has already packetized the rbu image and all the packets are now staged in this file. This driver also creates a new entry in /sys/devices/platform/dell_rbu/packet_size ; the user needs to echo the packet size here before downloading the packet file. The user should do the following: create one single file which has all the packets stacked together. echo the packet size in to /sys/devices/platform/dell_rbu/packet_size. echo 1 > /sys/class/firmware/dell_rbu/loading cat the packetfile > /sys/class/firmware/dell_rbu/data echo 0 > /sys/class/firmware/dell_rbu/loading The driver takes the file which came through /sys/class/firmware/dell_rbu/data and takes chunks of paket_size data from it and place in contiguous memory. This makes packet update process very efficient and fast. As all the packet update happens in one single operation. The user can still read back the downloaded file from /sys/devices/platform/dell_rbu/data.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | BUG fixes: The driver used to allocate memory with spinlock held which has been fixed in this patch. The driver was printing the entire buffer when it received a invalid entry in image_type. The fix is to only print a warning message and not the buffer. Usability enhancements: It is possible that due to user error the /sys/class/firmware/dell_rbu entries might be missing, this can happen if the user does the following echo 1 > /sys/class/firmware/dell_rbu/loading echo 0 > /sys/class/firmware/dell_rbu/loading This will make the entries in /sys/class/firmware/ to disappear and the only way get them back was bby unloading and loading the driver. This patch makes the user recreate these entries by echoing init in to image_type. This patch has been tested with Libsmbios and Dell OpenManage.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
