ISP1760 requires a delay of 90ns between programming the address and reading the data. Current driver solves this by a mdelay(1) which is very heavy weighted and slow. This patch applies the workaround from the ISP1760 FAQ by using two different banks for PTD and payload data and using a common wait for them. This wait is done by an additional ISP1760 access (whose timing constraints guarantee the 90ns delay). This improves speed when reading from an USB stick from: $ time dd if=/dev/sda of=/dev/zero bs=65536 count=1638 real 1m 15.43s user 0m 0.44s sys 0m 39.46s to $ time dd if=/dev/sda of=/dev/zero bs=65536 count=1638 real 0m 18.53s user 0m 0.16s sys 0m 12.97s [bigeasy@linutronix.de: fixed comment formating, moved define into header file, obey 80 char rule] Signed-off-by: NEnrico Scholz <enrico.scholz@sigma-chemnitz.de> Signed-off-by: NSebastian Siewior <bigeasy@linutronix.de> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

Update RX path handling in new serial gadget code to cope better with RX blockage: queue every RX packet until its contents can safely be passed up to the ldisc. Most of the RX path work is now done in the RX tasklet, instead of just the final "push to ldisc" step. This addresses some cases of data loss: - A longstanding serial gadget bug: when tty_insert_flip_string() didn't copy the entire buffer, the rest of the characters were dropped! Now that packet stays queued until the rest of its data is pushed to the ldisc. - Another longstanding issue: in the unlikely case that an RX transfer returns data and also reports a fault, that data is no longer discarded. - In the recently added RX throttling logic: it needs to stop pushing data into the TTY layer, instead of just not submitting new USB read requests. When the TTY is throttled long enough, backpressure will eventually make the OUT endpoint NAK. Also: an #ifdef is removed (no longer necessary); and start switching to a better convention for debug messages (prefix them with tty name).

This patch upgrades the support for the Sierra Wireless TRU-Install feature (i.e. zeroCD) to allow for future support of Linux enabled TRU-Install devices. By default all devices that do not have a Linux enabled TRU-Install device (i.e. the device does not have a Linux package on the virtual CD partition) will be switched into "modem mode." Devices that do contain a Linux package in the TRU-Install virtual CD will be allowed to enumerate as a CD-Rom so that either (a) a user can install the packaged software or (b) a user-space application (e.g. udev) can switch it to modem mode. This patch does allow for manual override by adding a usb-storage module parameter 'swi_tru_install' which can force the modem into either mode regardless of what packages it contains.

由 Alan Stern 提交于
This patch (as1119) will help to reduce the clutter of usb-storage's unusual_devs file by automatically detecting some devices that need the IGNORE_RESIDUE flag. The idea is that devices should never return a non-zero residue for an INQUIRY or a READ CAPACITY command unless they failed to transfer all the requested data. So if one of these commands transfers a standard amount of data but there is a positive residue, we know that the residue is bogus and we can set the flag.

This patch (as1114) fixes a problem that was revealed by an earlier patch (as1069b). Some broken controllers seem never to turn off their RHCS interrupt status bit, even when told to do so. As a result they generate an interrupt storm and hang the system. The patch avoids enabling RHSC interrupt requests when the RHCS status bit is already set. This should have no adverse affects on normal controllers, since they won't set the status bit until a root-hub status change actually occurs, in which case we wouldn't enable RHSC interrupt requests anyway -- we would wait until the status change had been processed and cleared.

This patch removes the auerswald USB driver from the linux kernel 2.6.26. This driver was included into the kernel mainly to connect to the ISDN framework. This was done in linux 2.4.x. For 2.6.x, due to the fragile and moving ISDN support, this connection was never realized, and the only use of this driver was for device configuration. In the age of DSL, the demand of ISDN support is getting very low. Meanwhile, with the advent of libusb, an userspace driver was done for the device configuration which works fine for linux and mac. (Thanks to the libusb developers!). The userspace driver is downloadable from the auerswald web site. So this driver is obsolete now and has to be removed.

Suresh wrote: These padlock instructions though don't use/touch SSE registers, but it behaves similar to other SSE instructions. For example, it might cause DNA faults when cr0.ts is set. While this is a spurious DNA trap, it might cause oops with the recent fpu code changes. This is the code sequence that is probably causing this problem: a) new app is getting exec'd and it is somewhere in between start_thread() and flush_old_exec() in the load_xyz_binary() b) At pont "a", task's fpu state (like TS_USEDFPU, used_math() etc) is cleared. c) Now we get an interrupt/softirq which starts using these encrypt/decrypt routines in the network stack. This generates a math fault (as cr0.ts is '1') which sets TS_USEDFPU and restores the math that is in the task's xstate. d) Return to exec code path, which does start_thread() which does free_thread_xstate() and sets xstate pointer to NULL while the TS_USEDFPU is still set. e) At the next context switch from the new exec'd task to another task, we have a scenarios where TS_USEDFPU is set but xstate pointer is null. This can cause an oops during unlazy_fpu() in __switch_to() Now: 1) This should happen with or with out pre-emption. Viro also encountered similar problem with out CONFIG_PREEMPT. 2) kernel_fpu_begin() and kernel_fpu_end() will fix this problem, because kernel_fpu_begin() will manually do a clts() and won't run in to the situation of setting TS_USEDFPU in step "c" above. 3) This was working before the fpu changes, because its a spurious math fault which doesn't corrupt any fpu/sse registers and the task's math state was always in an allocated state. With out the recent lazy fpu allocation changes, while we don't see oops, there is a possible race still present in older kernels(for example, while kernel is using kernel_fpu_begin() in some optimized clear/copy page and an interrupt/softirq happens which uses these padlock instructions generating DNA fault). This is the failing scenario that existed even before the lazy fpu allocation changes: 0. CPU's TS flag is set 1. kernel using FPU in some optimized copy routine and while doing kernel_fpu_begin() takes an interrupt just before doing clts() 2. Takes an interrupt and ipsec uses padlock instruction. And we take a DNA fault as TS flag is still set. 3. We handle the DNA fault and set TS_USEDFPU and clear cr0.ts 4. We complete the padlock routine 5. Go back to step-1, which resumes clts() in kernel_fpu_begin(), finishes the optimized copy routine and does kernel_fpu_end(). At this point, we have cr0.ts again set to '1' but the task's TS_USEFPU is stilll set and not cleared. 6. Now kernel resumes its user operation. And at the next context switch, kernel sees it has do a FP save as TS_USEDFPU is still set and then will do a unlazy_fpu() in __switch_to(). unlazy_fpu() will take a DNA fault, as cr0.ts is '1' and now, because we are in __switch_to(), math_state_restore() will get confused and will restore the next task's FP state and will save it in prev tasks's FP state. Remember, in __switch_to() we are already on the stack of the next task but take a DNA fault for the prev task. This causes the fpu leakage. Fix the padlock instruction usage by calling them inside the context of new routines irq_ts_save/restore(), which clear/restore cr0.ts manually in the interrupt context. This will not generate spurious DNA in the context of the interrupt which will fix the oops encountered and the possible FPU leakage issue.
