2020-03-03dp8393x: Don't stop reception upon RBE interrupt assertionFinn Thain
Section 3.4.7 of the datasheet explains that, The RBE bit in the Interrupt Status register is set when the SONIC finishes using the second to last receive buffer and reads the last RRA descriptor. Actually, the SONIC is not truly out of resources, but gives the system an early warning of an impending out of resources condition. RBE does not mean actual receive buffer exhaustion, and reception should not be stopped. This is important because Linux will not check and clear the RBE interrupt until it receives another packet. But that won't happen if can_receive returns false. This bug causes the SONIC to become deaf (until reset). Fix this with a new flag to indicate actual receive buffer exhaustion.

2020-03-03dp8393x: Clear descriptor in_use field to release packetFinn Thain
When the SONIC receives a packet into the last available descriptor, it retains ownership of that descriptor for as long as necessary. Section 3.4.7 of the datasheet says, When the system appends more descriptors, the SONIC releases ownership of the descriptor after writing 0000h to the RXpkt.in_use field. The packet can now be processed by the host, so raise a PKTRX interrupt, just like the normal case.

2020-03-03dp8393x: Pad frames to word or long word boundaryFinn Thain
The existing code has a bug where the Remaining Buffer Word Count (RBWC) is calculated with a truncating division, which gives the wrong result for odd-sized packets. Section 1.4.1 of the datasheet says, Once the end of the packet has been reached, the serializer will fill out the last word (16-bit mode) or long word (32-bit mode) if the last byte did not end on a word or long word boundary respectively. The fill byte will be 0FFh. Implement buffer padding so that buffer limits are correctly enforced.

2020-03-03dp8393x: Use long-word-aligned RRA pointers in 32-bit modeFinn Thain
Section 3.4.1 of the datasheet says, The alignment of the RRA is confined to either word or long word boundaries, depending upon the data width mode. In 16-bit mode, the RRA must be aligned to a word boundary (A0 is always zero) and in 32-bit mode, the RRA is aligned to a long word boundary (A0 and A1 are always zero).

Add a bounds check to prevent a large packet from causing a buffer overflow. This is defensive programming -- I haven't actually tried sending an oversized packet or a jumbo ethernet frame.

2020-03-03dp8393x: Always use 32-bit accessesFinn Thain
The DP83932 and DP83934 have 32 data lines. The datasheet says, Data Bus: These bidirectional lines are used to transfer data on the system bus. When the SONIC is a bus master, 16-bit data is transferred on D15-D0 and 32-bit data is transferred on D31-D0. When the SONIC is accessed as a slave, register data is driven onto lines D15-D0. D31-D16 are held TRI-STATE if SONIC is in 16-bit mode. If SONIC is in 32-bit mode, they are driven, but invalid. Always use 32-bit accesses both as bus master and bus slave. Force the MSW to zero in bus master mode. This gets the Linux 'jazzsonic' driver working, and avoids the need for prior hacks to make the NetBSD 'sn' driver work.

2020-02-20Avoid address_space_rw() with a constant is_write argumentPeter Maydell
The address_space_rw() function allows either reads or writes depending on the is_write argument passed to it; this is useful when the direction of the access is determined programmatically (as for instance when handling the KVM_EXIT_MMIO exit reason). Under the hood it just calls either address_space_write() or address_space_read_full(). We also use it a lot with a constant is_write argument, though, which has two issues: * when reading "address_space_rw(..., 1)" this is less immediately clear to the reader as being a write than "address_space_write(...)" * calling address_space_rw() bypasses the optimization in address_space_read() that fast-paths reads of a fixed length This commit was produced with the included Coccinelle script scripts/coccinelle/exec_rw_const.cocci.

into staging Clean-ups: qom-ify serial and remove QDEV_PROP_PTR Hi, QDEV_PROP_PTR is marked in multiple places as "FIXME/TODO/remove me". In most cases, it can be easily replaced with QDEV_PROP_LINK when the pointer points to an Object. There are a few places where such substitution isn't possible. For those places, it seems reasonable to use a specific setter method instead, and keep the user_creatable = false. In other places, proper usage of qdev or other facilies is the solution. The serial code wasn't converted to qdev, which makes it a bit more archaic to deal with. Let's convert it first, so we can more easily embed it from other devices, and re-export some properties and drop QDEV_PROP_PTR usage. # gpg: Signature made Tue 07 Jan 2020 15:01:26 GMT # gpg: using RSA key 87A9BD933F87C606D276F62DDAE8E10975969CE5 # gpg: issuer "marcandre.lureau@redhat.com" # gpg: Good signature from "Marc-André Lureau <marcandre.lureau@redhat.com>" [full] # gpg: aka "Marc-André Lureau <marcandre.lureau@gmail.com>" [full] # Primary key fingerprint: 87A9 BD93 3F87 C606 D276 F62D DAE8 E109 7596 9CE5 * remotes/elmarco/tags/prop-ptr-pull-request: (37 commits) qdev/qom: remove some TODO limitations now that PROP_PTR is gone qdev: remove QDEV_PROP_PTR qdev: remove PROP_MEMORY_REGION omap-gpio: remove PROP_PTR omap-i2c: remove PROP_PTR omap-intc: remove PROP_PTR smbus-eeprom: remove PROP_PTR cris: improve passing PIC interrupt vector to the CPU mips/cps: fix setting saar property qdev: use g_strcmp0() instead of open-coding it leon3: use qdev gpio facilities for the PIL leon3: use qemu_irq framework instead of callback as property dp8393x: replace PROP_PTR with PROP_LINK etraxfs: remove PROP_PTR usage lance: replace PROP_PTR with PROP_LINK vmmouse: replace PROP_PTR with PROP_LINK sm501: make SerialMM a child, export chardev property mips: use sysbus_mmio_get_region() instead of internal fields mips: use sysbus_add_io() mips: baudbase is 115200 by default ...

2019-12-18qemu_log_lock/unlock now preserves the qemu_logfile handle.Robert Foley
qemu_log_lock() now returns a handle and qemu_log_unlock() receives a handle to unlock. This allows for changing the handle during logging and ensures the lock() and unlock() are for the same file. Also in target/tilegx/translate.c removed the qemu_log_lock()/unlock() calls (and the log("\n")), since the translator can longjmp out of the loop if it attempts to translate an instruction in an inaccessible page.

The Aspeed MII model has a link pointing to its associated FTGMAC100 NIC in the machine. Change the "nic" property definition so that it explicitly sets the pointer. The property isn't optional : not being able to set the link is a bug and QEMU should rather abort than exit in this case.

2019-12-02net/virtio: Fix failover error handling crash bugsMarkus Armbruster
Functions that take an Error ** parameter to pass an error to the caller expect the parameter to point to null. failover_replug_primary() violates this precondition in several places: * After qemu_opts_from_qdict() failed, *errp is no longer null. Passing it to error_setg() is wrong, and will trip the assertion in error_setv(). Messed up in commit 150ab54aa6 "net/virtio: fix re-plugging of primary device". Simply drop the error_setg(). * Passing @errp to qemu_opt_set_bool(), hotplug_handler_pre_plug(), and hotplug_handler_plug() is wrong. If one of the first two fails, *errp is no longer null. Risks tripping the same assertion. Moreover, continuing after such errors is unsafe. Messed up in commit 9711cd0dfc "net/virtio: add failover support". Fix by handling each error properly. failover_replug_primary() crashes when passed a null @errp. Also messed up in commit 9711cd0dfc. This bug can't bite as no caller actually passes null. Fix it anyway. Fixes: 9711cd0dfc3fa414f7f64935713c07134ae67971 Fixes: 150ab54aa6934583180f88a2bd540bc6fc4fbff3 Cc: Jens Freimann <jfreimann@redhat.com> Cc: Michael S.

2019-12-02net/virtio: Drop useless n->primary_dev not null checksMarkus Armbruster
virtio_net_handle_migration_primary() returns early when it can't ensure n->primary_dev is non-null. Checking it again right after that early return is redundant. Drop. If n->primary_dev is null on entering failover_replug_primary(), @pdev will become null, and pdev->partially_hotplugged will crash. Checking n->primary_dev later is useless. It can't actually be null, because its caller virtio_net_handle_migration_primary() ensures it isn't. Drop the useless check. Cc: Jens Freimann <jfreimann@redhat.com> Cc: Michael S.
