* efi: payload: rename CONFIG_EFI_BOOTUP to CONFIG_EFI_PAYLOADAhmad Fatoum2024-03-051-2/+2
| | | | | | | | | | The symbol is internal, so we don't break anything by renaming it. CONFIG_EFI_PAYLOAD is clearer in intent, as BOOTUP doesn't clearly indificate whether barebox would act as EFI payload or as EFI loader.

* tftp: implement UDP reorder cache using listsSascha Hauer2022-09-221-22/+0
| | | | | | | | The UDP reorder cache can be much easier implemented using lists. As a bonus the cache grows and shrinks on demand and no fixed size has to be configured at compile time. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* tftp: reorder tftp packetsEnrico Scholz2022-09-121-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the tftp "windowsize" option, reordering of udp datagrams becomes an issue. Depending on the network topology, this reordering occurs several times with large tftp transfers and will heavily reduce the transfer speed. This patch adds a packet cache so that datagrams can be reassembled in the correct order. Because it increases memory usage and barebox binary size, it is an Kconfig option. bloat-o-meter reports with a non-zero FS_TFTP_REORDER_CACHE_SIZE | add/remove: 3/0 grow/shrink: 4/0 up/down: 916/0 (916) | Function old new delta | tftp_handler 920 1244 +324 | tftp_put_data - 184 +184 | tftp_window_cache_remove - 124 +124 | tftp_window_cache_get_pos - 120 +120 | tftp_allocate_transfer 104 188 +84 | tftp_do_close 260 312 +52 | tftp_send 384 412 +28 | Total: Before=630104, After=631020, chg +0.15% After setting FS_TFTP_REORDER_CACHE_SIZE Kconfig option to 0, numbers are going down to | add/remove: 0/0 grow/shrink: 3/0 up/down: 152/0 (152) | Function old new delta | tftp_handler 920 1012 +92 | tftp_allocate_transfer 104 136 +32 | tftp_send 384 412 +28 | Total: Before=630104, After=630256, chg +0.02% Signed-off-by: Enrico Scholz <enrico.scholz@sigma-chemnitz.de> Link: https://lore.barebox.org/20220830073816.2694734-19-enrico.scholz@sigma-chemnitz.de Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* fs: dentry cache implementationSascha Hauer2018-07-111-0/+23
| | | | | | | | | | | | | | | | | | | | | | | This adds the Linux dentry cache implementation to barebox. Until now every filesystem driver resolves the full path to a file for itself. This leads to code duplication and is error prone since resolving paths is a complicated task. Also it can narrow down the lookup performance since barebox only knows ASCII paths and has no way of caching lookups. With this patch we get the Linux dcache implementation. The path resolving code from fs/namei.c is nearly taken as-is, minus the RCU and locking code. Dcaching is made simple as of now: We simply cache everything and never release any dentries. Although we do reference counting for inodes and dentries it is effectively not used yet. We never free anything until a fs is unmounted in which case we free everything no matter if references are taken or not. This patch also contains a wrapper in fs/legacy.c to support filesystems with the old API. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* | fs: Add pstore filesystemMarkus Pargmann2015-12-101-0/+2
|/ | | | | | | | | | | | | | | | pstore is a persistent storage filesystem used for RAMOOPS. It is used to store console logs, panics, ftrace and other information in case of a crash/panic/oops/reboot. pstore is implemented for barebox as a read-only filesystem at the moment. It may be extended later on. The idea is to provide a way to extract essential data from the last running kernel. Most of the code is copied from the kernel.

* Add automount supportSascha Hauer2012-03-181-0/+3
| | | | | | | | | | | | | | This patch adds an automount command which makes it possible to execute a script when a certain directory is first accessed. It's the commands responsibility to make this directory available (bringing devices up and mounting it). This results in automount support which makes sure that from the shell every file can be accessed without having to care for device bringup. Bringing up devices may be expensive (USB, dhcp). The automount support makes it easy for the environment to bringup devices when they are actually needed. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Add suport for tftp as a filesystemSascha Hauer2012-02-191-0/+4
| | | | | | | | | | | | | | | | | | This adds tftp filesystem support. It currently duplicates significant amounts of the tftp (command) support. This is ok since we can eventually drop the original tftp command later. tftp is not really suitable to be handled as a filesystem. It lacks support for stat, reading directories and other things. Handling it as a filesystem has one big advantage though: tftp is no special case for boot scripts and/or commands anymore which makes them simpler. This implementation has some improvements to the original tftp command. It supports blocksize negotiation which speeds up transfers if the tftp server supports it. Also we can determine the filesize to transfer if the remote end supports it. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
