2015-09-11dfu: mmc: buffer file reads tooStephen Warren
When writing to files in a filesystem on MMC, dfu_mmc.c buffers up the entire file content until the end of the transaction, at which point the file is written in one go. This allows writing files larger than the USB transfer size (CONFIG_SYS_DFU_DATA_BUF_SIZE); the maximum written file size is CONFIG_SYS_DFU_MAX_FILE_SIZE (the size of the temporary buffer). The current file reading code does not do any buffering, and so limits the maximum read file size to the USB transfer size. Enhance the code to do the same kind of buffering as the write path, so the same file size limits apply. Remove the size checking code from dfu_read() since all read paths now support larger files than the USB transfer buffer.

2015-09-11dfu: don't keep freeing/reallocatingStephen Warren
DFU currently allocates buffer memory at the start of each data transfer operation and frees it at the end. Especially since memalign() is used to allocate the buffer, and various other allocations happen during the transfer, this can expose the code to heap fragmentation, which prevents the allocation from succeeding on subsequent transfers. Fix the code to allocate the buffer once when DFU mode is initialized, and free the buffer once when DFU mode is exited, to reduce the exposure to heap fragmentation. The failure mode is: // Internally to memalign(), this allocates a lot more than s to guarantee // that alignment can occur, then returns chunks of memory at the start/ // end of the allocated buffer to the heap. p = memalign(a, s); // Various other malloc()s occur here, some of which allocate the RAM // immediately before/after "p". // // DFU transfer is complete, so buffer is released. free(p); // By chance, no other malloc()/free() here, in DFU at least. // // A new DFU transfer starts, so the buffer is allocated again. // In theory this should succeed since we just free()d a buffer of the // same size. However, this fails because memalign() internally attempts // to allocate much more than "s", yet free(p) above only free()d a // little more than "s". p = memalign(a, s); Signed-off-by: Stephen Warren <swarren@nvidia.com> Acked-by: Lukasz Majewski <l.majewski@samsung.com> Tested-by: Lukasz Majewski <l.majewski@samsung.com>

2015-03-09dfu: mmc: file buffer: remove static allocationPrzemyslaw Marczak
For writing files, DFU implementation requires the file buffer with the len at least of file size. For big files it requires the same big buffer. Previously the file buffer was allocated as a static variable, so it was a part of U-Boot .bss section. For 32MiB len of buffer we have 32MiB of additional space, required for this section. The .bss needs to be cleared after the relocation. This introduces an additional boot delay at every start, but usually the dfu feature is not required at the standard boot, so the buffer should be allocated only if required. This patch removes the static allocation of this buffer, and alloc it with memalign after first call of function: - dfu_fill_entity_mmc() and the buffer is freed on dfu_free_entity() call. This was tested on Trats2. A quick test with trace. Boot time from start to main_loop() entry: - ~888ms - before this change (arch memset enabled for .bss clear) - ~464ms - after this change Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Reviewed-by: Simon Glass <sjg@chromium.org> Cc: Lukasz Majewski <l.majewski@samsung.com> Cc: Stephen Warren <swarren@nvidia.com> Cc: Pantelis Antoniou <panto@antoniou-consulting.com> Cc: Tom Rini <trini@konsulko.com> Cc: Marek Vasut <marek.vasut@gmail.com>

And the the memalign will return non null pointer for size 0. This could possibly cause data abort, so now the value of var is checked before use.

2014-09-02dfu: Provide means to find difference between dfu-util -e and -RLukasz Majewski
This commit provides distinction between DFU device detach and reset. The -R behavior is preserved with proper handling of the dfu-util's -e switch, which detach the DFU device. By running dfu-util -e; one can force device to finish the execution of dfu command on target and execute some other scripted commands. Moreover, some naming has been changed - the dfu_reset() method now is known as dfu_detach(). New name better reflects the purpose of the code. It was also necessary to increase the number of usb_gadget_handle_interrupts() calls since we also must wait for detection of the USB reset event. Example usage: 1. -e (detach) switch dfu-util -a0 -D file1.bin;dfu-util -a3 -D uImage;dfu-util -e access to u-boot prompt. 2. -R (reset) switch dfu-util -a0 -D file1.bin;dfu-util -R -a3 -D uImage target board reset Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Reviewed-by: Stephen Warren <swarren@nvidia.com> Tested-by: Stephen Warren <swarren@nvidia.com>

2014-08-09dfu: allow backend to specify a maximum buffer sizeStephen Warren
CONFIG_SYS_DFU_DATA_BUF_SIZE may be large to allow for FAT/ext layouts to transfer large files. However, this means that individual write operations will take a long time. Allow backends to specify a maximum buffer size, so that each write operation is limited to a smaller data block. This prevents the DFU protocol from timing out when e.g. writing to SPI flash. I would guess that NAND might benefit from setting this value too, but I can't test that. Signed-off-by: Stephen Warren <swarren@nvidia.com>

2014-08-09dfu: add write error handlingStephen Warren
Fix calls to dfu_write() and dfu_flush() to detect errors in the I/O itself. This could happen due to problems with the storage medium, or simply when trying to write a FAT/ext file that is larger than the buffer dfu_mmc.c maintains for this purpose. Signal the error by switching the DFU state/status. This will be picked up by the DFU client when it sends the next DFU request. Note that errors can't simply be returned from e.g. dnload_request_complete(), since that function has no way to pass errors back to the DFU client; a call to dnload_request_complete() simply means that a USB OUT completed. This error state/status needs to be cleared when the next DFU client connects. While there is a DFU_CLRSTATUS request, no DFU client seems to send this. Hence, clear this when selecting the USB alternate setting on the USB interface. Finally, dfu.c relies on a call to dfu_flush() to clear up the internal state of the write transaction. Now that errors in dfu_write() are detected, dfu_flush() may no longer be called for every transaction. Separate out the cleanup code into a new function, and call it whenever dfu_write() fails, as well as from any call to dfu_flush(). Signed-off-by: Stephen Warren <swarren@nvidia.com>
2014-08-09dfu: fix some issues with reads/uploadsStephen Warren
DFU read support appears to rely upon dfu->read_medium() updating the passed-by-reference len parameter to indicate the remaining size available for reading. dfu_read_medium_mmc() never does this, and the implementation of dfu_read_medium_nand() will only work if called just once; it hard-codes the value to the total size of the NAND device irrespective of read offset. I believe that overloading dfu->read_medium() is confusing. As such, this patch introduces a new function dfu->get_medium_size() which can be used to explicitly find out the medium size, and nothing else. dfu_read() is modified to use this function to set the initial value for dfu->r_left, rather than attempting to use the side-effects of dfu->read_medium() for this purpose. Due to this change, dfu_read() must initially set dfu->b_left to 0, since no data has been read. dfu_read_buffer_fill() must also be modified not to adjust dfu->r_left when simply copying data from dfu->i_buf_start to the upload request buffer. r_left represents the amount of data left to be read from HW. That value is not affected by the memcpy(), but only by calls to dfu->read_medium(). After this change, I can read from either a 4MB or 1.5MB chunk of a 4MB eMMC boot partion with CONFIG_SYS_DFU_DATA_BUF_SIZE==1MB. Without this change, attempting to do that would result in DFU read returning no data at all due to r_left never being set. Signed-off-by: Stephen Warren <swarren@nvidia.com>

DFU spec mentions it as a method to upgrade firmware (software stored in writable non-volatile memory). It also says other potential uses of DFU is beyond scope of the spec. Here such a beyond the scope use is being attempted - directly pumping binary images from host via USB to RAM. This facility is a developer centric one in that it gives advantage over upgrading non-volatile memory for testing new images every time during development and/or testing. Directly putting image onto RAM would speed up upgrade process. This and convenience was the initial thoughts that led to doing this, speed improvement over MMC was only 1 second though - 6 sec on RAM as opposed to 7 sec on MMC in beagle bone, perhaps enabling cache and/or optimizing DFU framework to avoid multiple copy for ram (if worth) may help, and on other platforms and other boot media like NAND maybe improvement would be higher. And for a platform that doesn't yet have proper DFU suppport for non-volatile media's, DFU to RAM can be used. Another minor advantage would be to increase life of mmc/nand as it would be less used during development/testing. usage: <image name> ram <start address> <size> eg. kernel ram 0x81000000 0x1000000 Downloading images to RAM using DFU is not something new, this is acheived in openmoko also. DFU on RAM can be used for extracting RAM contents to host using dfu upload. Perhaps this can be extended to io for squeezing out register dump through usb, if it is worth.
