* pcidev.c: populate IDs with pci_fill_info()Daniel Verkamp2020-10-141-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | With pciutils 3.7.0, flashrom is unable to match any PCI devices by vendor/device ID because the vendor_id and device_id fields of struct pci_dev are not filled in. Call pci_fill_info() to request these identifiers before trying to match them against the supported device list. The pciutils ChangeLog for 3.7.0 mentions that the documentation and back-end behavior for pci_fill_info() was updated; it seems that a call to pci_fill_info() was always intended to be required, but some backends (such as the sysfs one used on Linux) would fill the identifier fields even when not requested by the user. The pci_fill_info() function and the PCI_FILL_IDENT flag have been available for all versions of pciutils since at least 2.0 from 1999, so it should be safe to add without any version checks. With this change, reading/writing a nicintel_spi boot ROM is successful.

* rpci: Use pci_dev struct pointer to avoid API breaksYouness Alaoui2017-08-101-9/+15
| | | | | | | | | | | | | | | | | | | | | | The pci_dev structure is never meant to be used as is, but always as a pointer. By using the struct itself in undo_pci_write_data, we are risking data corruption, or buffer overflows if the structure size changes. This is especially apparent on my system where flashrom segfaults because I compile it with pciutils 3.3.0 and I run it on a system with pciutils 3.5.2. The struture size is different and causes a struct with the wrong size to be sent to the library, with invalid internal field values.

| | | | | | | | | | | | | | | | | | | Previously the internal programmer used its own code to initialize pcilib. This patch extracts the common code from the internal programmer and pcidev_init() into pcidev_init_common(). This fixes the non-existent PCI cleanup of the internal programmer and adds an additional safety by checking for an already existing PCI context. We got a nice shutdown function registration infrastructure, but did not use it very wisely. Instead we added shutdown functions to a myriad of programmers unnecessarily.

* Use shutdown callback mechanism to shutdown programmersDavid Hendricks2011-06-141-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch attempts to resolve some programmer shutdown ordering issues by having the programmer init functions register shutdown callbacks explicitly wherever it makes most sense. Before, assumptions were made that could lead to the internal programmer's state changing before the external programmer could be shut down properly. Now, each programmer cleans up after itself and (hopefully) performs each operation in the correct order. As a side-effect, this patch gives us a better usage model for reverse operations such as rpci_* and rmmio_*. In the long-run, this should make reversing the initialization process easier to understand, less tedious, and less error-prone. In short, this patch does the following: - Registers a shutdown callback during initialization for each programmer. - Kills the .shutdown function pointer from programmer_entry struct. Also, make most shutdown functions static. - Adds a few minor clean-ups and corrections (e.g. missing physunmap() calls).

* Split off programmer.h from flash.hCarl-Daniel Hailfinger2010-07-271-0/+1
| | | | | | | | | | | | | | | | | | | | | Programmer specific functions are of absolutely no interest to any file except those dealing with programmer specific actions (special SPI commands and the generic core). The new header structure is as follows (and yes, improvements are possible): flashchips.h flash chip IDs chipdrivers.h chip-specific read/write/... functions flash.h common header for all stuff that doesn't fit elsewhere hwaccess.h hardware access functions programmer.h programmer specific functions coreboot_tables.h header from coreboot, internal programmer only spi.h SPI command definitions Corresponding to flashrom svn r1112.

* Unify programmer parameter extractionCarl-Daniel Hailfinger2010-07-081-1/+1

* Various places in the flashrom source feature custom parameter extraction ↵Carl-Daniel Hailfinger2010-07-061-1/+4
| | | | | | | | | | | | | | | | | | | | from programmer_param This led to wildly differing syntax for programmer parameters, and it also voids pretty much every assumption you could make about programmer_param. The latter is a problem for libflashrom. Use extract_param everywhere, clean up related code and make it more foolproof. Add two instances of exit(1) where we have no option to return an error. Remove six instances of exit(1) where returning an error was possible. WARNING: This changes programmer parameter syntax for a few programmers! Corresponding to flashrom svn r1070.

* Kill global variables, constants and functions if local scope sufficesCarl-Daniel Hailfinger2010-07-031-4/+4
| | | | | | | | | | | | | | | | | | | | | | | Constify variables where possible. Initialize programmer-related variables explicitly in programmer_init to allow running programmer_init from a clean state after programmer_shutdown. Prohibit registering programmer shutdown functions before init or after shutdown. Kill some dead code. Rename global variables with namespace-polluting names. Use a previously unused locking helper function in sst49lfxxxc.c. This is needed for libflashrom. Effects on the binary size of flashrom are minimal (300 bytes shrinkage), but the data section shrinks by 4384 bytes, and that's a good thing if flashrom is operating in constrained envionments.

* PCI device BARs of all types had only bits 1:0 cleared while reading the addressCarl-Daniel Hailfinger2010-03-171-1/+17
| | | | | | | | | | | | That was correct for IO BARs, but failed to mask bit 3:2 for MEM BARs, resulting in odd offsets for prefetchable MEM BARs and for 64-bit capable MEM BARs. Mask the correct number of bits for all types of BARs and add some debug printing about BAR type. Corresponding to flashrom svn r946.

* Add initial support for flashing some NVIDIA graphics cardsUwe Hermann2009-09-301-5/+11
| | | | | | | | | | | | | | | | | | | | The new option is '-p gfxnvidia', rest of the interface is as usual. I tested a successful identify and read on a "RIVA TNT2 Model 64/Model 64 Pro" card for now, erase and write did NOT work properly so far! Please do not attempt to write/erase cards yet, unless you can recover! In addition to the NVIDIA handling code it was required to call programmer_shutdown() in a lot more places, otherwise the graphics card will be disabled in the init function, but never enabled again as the shutdown function is not called. The shutdown handling may be changed to use atexit() later. Corresponding to flashrom svn r737. Signed-off-by: Uwe Hermann <uwe@hermann-uwe.de> Acked-by: Luc Verhaegen <libv@skynet.be>
