* PCMCIA / PM: Avoid noirq suspend aborts during suspend-to-idleRafael J. Wysocki2018-02-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a problem with PCMCIA system resume callbacks with respect to suspend-to-idle in which the ->suspend_noirq() callback may be invoked after the ->resume_noirq() one without resuming the system entirely in some cases. This doesn't work for PCMCIA because of the lack of symmetry between its system suspend and system resume "noirq" callbacks. The system resume handling in PCMCIA is split between socket_early_resume() and socket_late_resume() which are called in different phases of system resume and both need to run for socket_suspend() (invoked by the system suspend "noirq" callback) to work. Specifically, socket_suspend() returns an error when called after socket_early_resume() without socket_late_resume(), so if the suspend-to-idle core detects a spurious wakeup event and attempts to put the system back to sleep, that is aborted by the error coming from socket_suspend(). Avoid that by using a new socket state flag, SOCKET_IN_RESUME, to indicate that socket_early_resume() has already run for the socket in which case socket_suspend() will do minimum handling and return 0. This change has been tested on my venerable Toshiba Portege R500 (which is where the problem has been discovered in the first place), but admittedly I have no PCMCIA cards to test along with the socket itself.

* pcmcia: convert pcmcia_request_configuration to pcmcia_enable_deviceDominik Brodowski2010-09-291-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | pcmcia_enable_device() now replaces pcmcia_request_configuration(). Instead of config_req_t, all necessary flags are either passed as a parameter to pcmcia_enable_device(), or (in rare circumstances) set in struct pcmcia_device -> flags. With the last remaining user of include/pcmcia/cs.h gone, remove all references.

* pcmcia: simplify IntTypeDominik Brodowski2010-09-291-1/+0
| | | | | | | | | | | | | | | | | | | | | | IntType was only set to INT_MEMORY (driver pcmciamtd) or INT_MEMORY_AND_IO (all other drivers). As this flags seems to relate to ioport access, make it conditional to the driver having requested IO port access. There are two drivers which do not request IO ports, but did set INT_MEMORY_AND_IO: ray_cs and b43. For those, we consistently only set INT_MEMORY in future.

* pcmcia: Change window_handle_t logic to unsigned longMagnus Damm2009-11-281-2/+2
| | | | | | | | | | | | | | | | | | | | | | | Logic changes based on top of the other patches: This set of patches changed window_handle_t from being a pointer to an unsigned long. The unsigned long is now a simple index into socket->win[]. Going from a pointer to unsigned long should leave the user space interface unchanged unless I'm mistaken. This change results in code that is less error prone and a user space interface which is much cleaner and safer. A nice side effect is that we are also are able to remove all members except one from window_t. [ linux@dominikbrodowski.net: Update to 2.6.31. Also, a plain "index" to socket->win[] does not work, as several codepaths rely on "window_handle_t" being non-zero if used. Therefore, set the window_handle_t to the socket->win[] index + 1. ] CC: netdev@vger.kernel.org Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>

* pcmcia: add new CIS access helpersDominik Brodowski2009-11-081-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | As a replacement to pcmcia_get_{first,next}_tuple() and pcmcia_get_tuple_data(), three new -- and easier to use -- functions are added: - pcmcia_get_tuple() to get the very first CIS entry of one type. - pcmcia_loop_tuple() to loop over all CIS entries of one type. - pcmcia_get_mac_from_cis() to read out the hardware MAC address from CISTPL_FUNCE. Only a handful of drivers need these functions anyway, as most CIS access is already handled by pcmcia_loop_config(), which now shares the same backed (pccard_loop_tuple()) with pcmcia_loop_tuple().

| | | | | | | | | | | | | | | | | pccard_read_tuple(), which is only used by the PCMCIA core, should handle TUPLE_RETURN_COMMON more sensibly: If a specific function (which may be 0) is requested, set tuple.Attributes = 0 as was done in all PCMCIA drivers. If, however, BIND_FN_ALL is requested, return the "common" tuple. As to the callers of pccard_read_tuple(): - All calls to pcmcia_validate_cis() had set the "function" parameter to BIND_FN_ALL. Therefore, remove the "function" parameter and make the parameter to pccard_read_tuple explicit. - Calls to CISTPL_VERS_1 and CISTPL_MANFID now set BIND_FN_ALL.
